Frequently Asked Questions

Mechanical Fuel Injection:

Q:  Can I use a Mechanical Fuel injection system on the street?
A:  Mechanical Fuel injection is not recommended for street applications. There is no partial throttle.

When I purchase an Injector Hat, will I have to set it up myself?
A:  All Hat assemblies purchased from Good Vibrations are setup and calibrated per application and will include a base line setup and additional pills for the end user to fine tune with.

Q: How do I prime my Fuel Injection System?
A: You can prime your system manually by squirting High Octane gasoline into the injector hat through the butterflies or you can go with an onboard priming system that utilizes an electric pump that can be activated from inside the cockpit.

Q: My barrel valve is leaking what should I do?
A:  Most leaks can be easily fixed with an O-ring kit. However, if there is damage to the barrel valve or its components then you may have to replace it depending on where the damage is located.   

Q: What can I do to keep my shutoff valve from vibrating closed during a pass?
A: The over-center spring bracket is designed to keep the shutoff valve positively in the ON position until it is turned off manually.

How can I figure what size injector I have?
A: The best way to figure out what injector you have is to first confirm the manufacturer. If it is an Enderle hat you can simply measure the butterfly diameter and visit our Fuel Injection tech page at the below link to view our schematic of injector hats.

Q: How do I know if my fuel pump is belt or cam driven?
A: To figure out the rotation of your Enderle fuel pump, place the outlet at the 12 o'clock position and if the notch on the pump cover is at the 3 o'clock position it is Cam driven. If it is at the 9 o'clock position it is belt driven. Click link for reference:

Q: How can I tell what size fuel shutoff valve I have?   
A: You can measure the diameter of the brass ring behind the arm. (3/4in = AN6) (1in = AN8)

Q: Will the Enderle Big Block Chevy front cover work on all Generation blocks?
A: Enderle Chevy front cover will only work on a Gen 4 block.

Q: How can I tell if the metering piston in my barrel valve is the correct one?
A: The square style barrel valve can have 3 possible metering pistons a Blown Alcohol piston, a Blown Gas piston and a Tunnel Ram piston. The numbers that will be stamped on the serrated shaft portion of the piston is Blown Alcohol 17; Blown Gas 12; Tunnel Ram 32. If you have a K-Style barrel valve then it becomes more difficult to determine as you have to measure a notch that has been machined into the piston. Contact us for those measurements.

Q:  Can I use an Electronic fuel pump with a Mechanical Injection system?
A: No, you have to run a Mechanical pump with a Mechanical system. The reason for this is because Mechanical systems are ran off of your RPM’s and the fuel flow fluctuates with them. When you try and run an Electronic pump with them they tend to over fuel the systems at times and at other times cannot supply enough fuel.

Q:  Can I run my fuel tank in the rear of the vehicle?
A: The answer to that question is both yes and no. If you want to run only 1 fuel tank on this vehicle with a mechanical injection system the answer is No you cannot run that in the rear of the vehicle. The reason for this is due to the mechanical pumps being gravity fed and having virtually no suction power. When the vehicle launches the inertia will be pushing the fuel away from the pump and will lean it out and potentially damage the pump and possibly the motor as well which is why you will require a front mount tank.

If you are up for running 2 fuel tanks on you vehicle then the answer is yes you can run the Main cell in the rear. With this setup you will have to run a Surge Tank in the front of the vehicle with either float bowls on the side of it or a manual return out the top of the tank. This surge tank will need to be supplied with fuel from the main tank in the rear with an Electronic fuel pump with equal volume of the Mechanical pump you are using on your system. From the surge tank the mechanical pump will take over and feed the motor accordingly.


How much oil do I put in my supercharger?
A: You will want to fill it to the 7 O’clock bolt hole position where the snout mounts. Or approximately half way up the sight glass if your front cover has that installed. The amount required is usually between 16-20oz depending on the blower size.

Q: What type of oil do I run in my supercharger?
A: 80-90wt Gear Oil, NON-Synthetic and NON-Detergent.

Q: How many ft lbs do I torque my blower bolts/studs down to?
A: If using Steel bolts the recommended torque is 15-18lbs. When using the aluminum break away studs the recommended torque is 10-12lbs. *Keep in mind sometimes you may have to torque the rear Bolts/Studs down a little bit more than the front to prevent the rear of the blower from lifting*

Q: Is the Percent of Over/Under drive the same as the Boost my blower is creating?
A: No, that is not always the case. Sometime that can happen; however, the drive of the blower is how fast you are spinning it in relation to the crank shaft. The boost is the amount of PSI the blower is forcing into the motor at that given drive ratio. 

Q: Can I run a full Teflon Stripped blower on the Street?
A: No, we strongly recommend against running this type of blower on the street as most of the time the clearance is setup for Alcohol and it will build a lot more Heat in the motor due to those Strips.

Q: Do I need to run a crank hub or a Harmonic Balancer with a Blower?
A: That is a personal preference either for you or your engine builder. We recommend a crank hub to eliminate the excess weight of a balancer on the end of your crankshaft. Also when running a crank hub all accessory pulleys along with the blower pulley centers itself properly and bolts on using the 6 bolt pattern in the hub. If you are afraid of harmonics coming into play when running a crank hub, don’t be as the belt and pulleys act as an extremely large balancer and absorb the harmonics of the motor.

Q: What makes my blower surge?
A: This is caused by a Rich/Lean cycle at idle. As the motor leans out the RPM’s increase and richens up the motor, when the motor richens up the RPM’s decrease and the motor leans out. This continual cycle is known as “Blower Surge”. With proper tuning most of the surging can be eliminated.

Q: How tight should I run my belt?
A: Blower belt adjustment is usually done when the motor is cold and should have 3/4" deflection in or out on the long side of the belt. This will give you 1 1/2" total deflection. Once the motor is warmed up this will decrease substantially to 1/4" deflection or a total of 1/2" deflection. Be very careful not to over tighten your belt as you can cause severe damage to your blower and/or crankshaft.

Q: Which is stronger 1/2" pitch or 8mm?
A: The 8mm round tooth profile is capable of transferring as much as 40% more power than the 1/2" pitch profile. As a general rule 1/2" pitch is good for drive ratios up to 15% overdrive on most blower applications. Large blowers with High drive ratios should use 8mm or 14mm tooth profiles.

Q: When do I start making boost?
A: The amount of boost and the RPM at which boost starts is controlled by the throttle, blower size, drive ratio, engine size, camshaft profile, and exhaust system. All of these factors determine the breathing capabilities of a blown motor. Boost should only be measured at wide open throttle at 6,000 RPM or above. If there is only partial throttle the blower cannot get enough air to overcome the demand of the motor. Only when the blower can get enough air will it produce boost.

Q: Why does my blower motor run hot?
A: Overheating of a blown motor may be caused by one or more of the following:
·   Too high compression ratio
·   Too high blower drive ratio
·    Improper timing
·    Poor Water flow through the manifold
·    Inefficient Cooling system


Q: How much Mag do I really need for my application?
A: No one really knows the exact mag required for your specific application. However, below are the rules of thumb to go by when selecting a magneto for your application.

Circle Track – Street/Hot Rod: Std OAC Vertex or SprintMag (up to 2.5 amps)

Blown Gas: 2-3amp Vertex or SuperMag II

Mild Blown Alcohol (up to 10psi): 3amp Vertex or SuperMag III

Moderate Blown Alcohol (up to 30psi): 4amp Vertex or SuperMag IV

Hardcore Blown Alcohol (30psi and Above): 6amp OXC Vertex or 6amp SuperMag V

Injected Nitro (up to 50%): 4amp Vertex or SuperMag IV

Injected Nitro (up to 100%): 6amp OXC Vertex or 6amp SuperMag V

Blown Nitro: 7-8amp SuperMag V

Q: How long will my magnets stay charged?
A: It is hard to determine when exactly your magnets will lose their charge as it depends on how often the motor is being ran and what is being done to it. However, they will not lose their charge by just sitting on a shelf or not being ran.

Q: How often should I get my Magneto Serviced?
A: If you are getting 50 or so passes per year on your car or the motor is spinning less than a few hours total (circle track) then you will be fine with servicing the magneto every other season. If you are putting much more than 50 passes per year on your car you will want to have that serviced every year. And if you are putting passes on your car every week or every other week and you feel the ignition getting weak then you will want to get your magneto serviced regularly (multiple times a year) or consider investing in Rare Earth magnets which do not need recharging.

Q: My motor will not start, there seems to be no spark. Are my magnets dead?
A: The magnets most likely are not dead as they never lose their charge completely. They lose energy slowly with use after a charge until the reach a certain point & then stabilize. It is more likely the coil has failed, the Points are fouled or there is a short somewhere. The magnet never gets so weak that it will not produce a spark unless the plug gap is well over .020in or the magnet has been demagnetized.

Q: If a Magneto is so powerful why do I have to run a .018 - .020in plug gap?
A:  By running a tight gap on a magneto you are making sure the spark gets to the plug properly. When running a wider gap than that with a magneto you may end up with the spark arcing to other objects in the magneto or crossfire between plug wires. The spark finds the path of least resistance, hence the reason why you want a tight gap on the plug so it does not find an easier path.

Q: Which Coil Should I use with my SuperMag?
A: There are 4 different coils that you can use depending on what SuperMag you are running.

·  Red-Top coil 28900A is designed to handle SprintMags and SuperMags up to 4.5amps.
·  Black-Top coil 28990 is designed to handle SuperMags between 4.5 – 6.5amps.
·  Monster coil 28901 is designed to handle any SuperMag over 5amps.
·  The Last coil is 28920 which is similar to the 28901 Monster coil. However, this coils is designed to be used with Naturally Aspirated or Blown Motors spinning below 8500rpm, as due to its voltage output spinning this coil over that RPM can result in Cross-firing.

Q:  Can I use a smaller 28900A or 28990 coil with my high amp magneto?
A: No, the 28900A & 28990 coils are designed to handle up to 6.5amps at the most. When running a Hot/High amp mag through the wrong coil, the spark duration ends up being very long which is not a good thing. When this occurs the spark last so long that it can jump to the wrong terminal in the cap. With that long spark duration there is not enough “Off-Time” to ensure the spark goes to the cylinder it should. Cross-firing in the cap & missing/sputtering under load are the symptoms.

Q: Can I use the Black-topped 28990 coil with my 3.5amp SuperMag?
A: You can if you would like to; however, you will not gain anything by doing so. What will most likely end up happening is that your motor will become difficult to start and will require faster cranking speeds in order to fire.

Q: Is there any specific way to mount my coil?
A: Yes, the coils are oil filled and the High Tension terminal should be at the lowest point (covered by oil internally) or they can fail. The best way to mount them is with the small primary terminals facing straight up and the High Tension terminal low and facing out the side. The next best way to mount them is with the High Tension terminal pointer straight down. Do Not mount the coil with the High Tension terminal facing straight up as it will fail on you.

Q: How can I tell what Rotation my mag is turning?
A: Most magnetos will have their rotation stamped on the Name tag on the generator portion. If you do not trust that or it is not stamped there then you will have to remove the cap and Rotor and look at the rotor drive plate. Aim the plate so it is facing up and down (12 O’clock & 6 O’clock). Now look at the dowel pins on the drive plate that locate the rotor. If the dowel pin in the 12 O’clock position is on the Right side then your mag is a Right Hand or Clock Wise rotation. If that dowel pin is on the Left side then you mag is a Left Hand or Counter Clock Wise rotation. 

Lucas Oil:


Q: How do I use Lucas Oil Stabilizer in my vehicle?
A: It is recommended that you add the Oil Stabilizer with every oil change (20% Stabilizer, 80% Oil). You may also use the stabilizer to top off between oil changes in order to help reduce oil consumption in an older engine, or maintain peak performance in a new engine.

Q: How many miles do I need to have on my vehicle before I can start using Lucas Oil Stabilizer?
A: You don't have to have a specific amount of wear before you start using our Oil Stabilizer. We use it in brand new engines ourselves! Put in a quart each time you change the oil in your car. You should be able to go at least 50% longer between oil changes and your engine will last much, much longer.

Q: Can I use Lucas Oil Stabilizer in anything else in my vehicle besides my engine?
A: Yes, In addition to being great for your engine, you can also mix it 25% / 75% in the transmission and 50% / 50% in the differential. Lucas Oil Stabilizer blends with any petroleum-based or synthetic oil, and is formulated for gasoline or diesel engines.

Q: Heavy Duty Oil Stabilizer seems pretty thick, Can I use it in my small car that requires light weight oil?
A: In newer and smaller vehicles that require light weight oils such as 5W- 30, we recommend our Pure Synthetic Oil Stabilizer. Pure Synthetic Stabilizer was developed specifically for engines that run on lighter weight

Q: Will using Lucas Stabilizer void the factory warranty on my new vehicle?
A: No, using Lucas Stabilizer will not void a new car warranty. Stabilizer is a 100% petroleum product that will blend with both synthetic and non- synthetic oils.


Q: Will using Lucas Stabilizer void the factory warranty on my new vehicle?
A: No, using Lucas Stabilizer will not void a new car warranty. Stabilizer is a 100% petroleum product that will blend with both synthetic and non- synthetic oils.

Q: Can I use Pure Synthetic Oil Stabilizer in non-synthetic oil?
A: Yes, contrary to common belief, you can mix synthetic and non-synthetic oil. A common reason for doing so is if your vehicle requires a light weight oil like 5W-30. Pure Synthetic Stabilizer was developed specifically for engines that run on lighter weight engine oils and in newer vehicles.

Q: Can I use Lucas Oil Stabilizer in anything else in my vehicle besides my engine?
A; Yes, In addition to being great for your engine, you can also mix it 25% / 75% in the transmission and 50% / 50% in the differential. Lucas Oil Stabilizer blends with any petroleum-based or synthetic oil, and is formulated for gasoline or diesel engines.


Q: Is your "Upper Cylinder Lubricant with Injector Cleaners" the same as "Lucas Fuel Treatment"?
Yes, the Upper Cylinder Lubricant with Injector Cleaners is the offical name for the product that most people refer to Lucas Fuel Treatment.

Q: Is this product made for gasoline or diesel engines?
A: Lucas Fuel Treatment was designed to clean and lubricate the fuel systems of both gasoline and diesel engines.

Q: How often can I use Lucas Fuel Treatment?
A: Since Lucas Fuel Treatment does not contain any solvents it is perfectly safe to run with every fill up. In fact, many of our users run our fuel treatment with every tank because they see an improvment in fuel mileage. The savings can be so great that in some cases the money you save in fuel pays for the product and then some.


Q: Will the Lucas Power Steering Stop Leak correct the squealing and hard spots in my steering?
A: Yes, the Lucas Power Steering Stop Leak will correct squealing and hard spots and fix most seal leaks in a worn rack and pinion. You can also use the Power Steering Stop Leak in new units to prevent wear.

Q: I noticed that your Power Steering Stop Leak says "Guaranteed" on the bottle. What do you mean?
A: We believe so strongly in our Power Steering Stop Leak that we guarantee it will stop your leaking power steering unit or your money back!

Q: My leak is getting better, is it safe to use more than one bottle of Power Steering Stop Leak?
A: Yes, in some cases two bottles may be required to stop a seal leak in your power steering unit.

Q: My power steering unit is cracked. Will Power Steering Stop Leak still work?
A: No, Lucas Power Steering Stop Leak is effective on seal leaks. Leaks resulting in physical damage to power steering units will require attention from your certified mechanic.


Q: How should I use Lucas Transmission Fix?
A: We recommend adding a bottle of Lucas Transmission Fix each time you change your transmission fluid (approximately every 30-40,000 miles), or adding a bottle to your current fluid to fix a small leak.

Piston Rings:

Q: Does Total Seal rings require special cylinder honing?
No, Total Seal rings do not require special cylinder honing. However, they like all piston rings do require the cylinders to be honed properly to start with. One of the most common causes of ring sealing issues today is improper cylinder honing.

Q: What advantages does the gapless top ring offer over the gapless 2nd ring?
The Total Seal gapless top ring is the natural evolution of the gapless second. By moving the gapless ring to the #1 ring groove they effectively seal with cylinder closer to the combustion chamber. This not only increases the cylinder seal on the compression and power strokes but also improves the ring seal in the intake stroke resulting in better cylinder filling on a normally aspirated engine. The increased amount of force generates by the combustion process in turn delivers a greater amount of energy to the crankshaft. The choice is yours and either ring offers superior cylinder sealing.

Q: Can I use gapless top or second rings on my blown alcohol motor?
Yes, we have used the gapless second rings on our blown motors for years with great success. The rings provide an unmatched sealing of the cylinder compared to conventional rings and keep the leakdown/blow-by of the cylinder to a minimum over longer periods of time, thus providing more power to the crankshaft with fewer teardowns.

Q: Can I use a gapless top ring if my piston is gas ported?
Yes, Gas porting aids in keeping any top ring seated in high RPM/ high cylinder pressure applications.

Q: When file fitting the gapless ring do I need to file the rail also?
Yes, the ring and the rail need to be filed*. Follow the gapping chart supplied with the ring set.
*The rail end gap can be larger than the primary ring but not smaller.

Q: Which way does the gapless ring go on the piston, rail side up or down?
The gapless ring is always installed rail side down.

Q: What should I set my end gaps to?
Please follow the gapping chart supplied with the ring set. Different applications require different amounts of gap. If for some reason the gapping chart is missing or you’re just not sure please click this link to view the gapping chart we have on our website.

Q: Can I break my engine in on synthetic oil?
Though we have seen it done successfully on occasion we do not recommend it. We have seen the best and most consistent results breaking the engine in on light viscosity conventional oil. Synthetics can be used after completing the break in process.

Q: What is Quickseat?
Quickseat is Total Seal’s patented dry film cylinder wall assembly lube. It is quite unique in that it is a dry lube that helps to prevent glazing of the rings from the over use of assembly oil. It also provides outstanding lubrication during the critical initial startup period helping to prevent ring scuffing and cylinder wall burnishing.

Pit Mats:

Q: What is a PitMat?
A PITMAT is an exclusive material that can be used on a variety of surfaces including gravel, dirt, grass, concrete, asphalt and recycled asphalt. Its primary purpose is to provide a clean durable surface to park and maintain your vehicle while at the track or at the shop, but can be used for many other applications.

Q: How much does a PitMat Weigh?
10' x 20' = 43 lbs
10' x 30' = 71 lbs
10' x 40' = 83 lbs
12' x 30' = 85 lbs
12' x 40' = 102 lbs
15' x 30' = 97 lbs
15' x 40' = 127 lbs

Q: What color are Pit Mats available in?
Black, Grey, Red, and Blue.

Q: How do I clean a PitMat?
Purchase the PITMATUSA Pitmat Cleaner, which was developed by a chemist for cleaning your PITMAT. Sold by the gallon. Pitmat Cleaner is a concentrated product, and should be diluted, although, depending upon your PITMAT'S condition, the water-to-product mixture will vary.

Q: Will the Mat Hold up to Floor Jacks and / or Pro Jacks?
Yes, as long as proper care was taken to remove rocks and debris before setting up your PITMAT. If using on asphalt it is recommended to sweep the area first before setting up. If you are on soft grass it's recommend to put some wood down to help support your jacks.


Q: How do Replay cameras match up to the GoPro’s?
The Replay cameras at this time are almost unmatched by the GoPro’s. This is due to the construction of the Replay cameras being machined from billet aluminum and not plastic. Also due to their billet camera mounts that allow you to attach the camera virtually anywhere on your race car. With Replay’s billet roll bar mounts it allows their camera to resist the vibrations of you race car and prevent video warpage that most see with the GoPro’s. This gives you clear consistent video footage of your pass for optimal feedback.

Q: How to clean the camera lens?
In order to clean the lens you will want to breathe gently on the lens to fog it up, then take a gentle cloth to wipe it with. This is the most effective way to clean the lens. Do not use chemicals or cleaning agents to clean this with.

Q: How to prevent wind noise?
Apply one of the supplied Wind Breakers to the bottom of your cameras mic hole to help suppress unwanted wind noise. Replay frequently makes improvements to their cameras mic tuning, so updating your camera to the latest firmware will ensure you have the best audio currently available.

Q: What MicroSD card should I buy?
We recommend using a Name Brand MicroSD cards with a class 10 or higher speed rating for maximum reliability. The 1080mini can only handle MicroSD cards up to 32gb. The PrimeX can handle SDXC cards up to 128gb.

Q: Camera shuts off while recording?

· Has the unit been charged? If not charge it fully and it should work fine.
· Is the Cameras SD card full? If so remove the videos from the SD card and/or replace with a new SD card.
· Has the SD card been formatted prior to recording? If not please reformat the SD card through the following link
· Is the camera in a high vibration application? If so then add a small layer of tape on the back of the SD card to build up thickness, preventing loss of contact while in the camera.
· If all other methods attempted, camera may be suffering from bad battery life.

Q: How do I adjust the Advance Settings on my 1080mini?
You can modify the advance settings by locating the XD1080MINI.txt file on your MicroSD card.

Q: The Blue LED light is flashing and then my 1080mini turns off?
The battery life is at 25% or less and needs to be recharged.

Q: Cannot Update the Firmware?
If the update is still not successful after following the instructions carefully with the SD card out, hold the reset button on the back of the camera down for at least 30 seconds.
· Insert SD card into camera and power on normally
· From the software update you downloaded, drag only the .bin file over to your cameras SD card (leave the existing DCIM, MISC, and 1080.txt files on the SD card). Insert SD card into the camera.
· Power unit on normally. You should see the Red and Blue LED’s stay solid and the Blue LED will blink rapidly. Once the Camera powers itself down, this will indicate the update was successful.
· Connect SD card back to your computer and remove the .bin file. If this in not done the camera will try and run the update every time it is powered on.
