Never use them. They show impressive leak down values but I have never seen them work going down the track.
If it was me I would enlarge it to be .028-.030
The second ring should be as wide as the top ring. This is to let the gases escape so it prevents ring flutter. Actually the ring can go bad and...
Have you checked your valve spring. Broken or weak springs can cause that
OWhat do you gap your plugs at and how old are your plug wires
Need to add a little variety here to the Pitt Buzz, more on blown ProMods. What a two week adventure I had with Swedish Flamholc Racing PM team...
If you look at the alcohol flow path it had to have either come from debris in the tank or the hose to the pump or the hose to the BV or the...
I agree with Mark. If you have poppets that return fuel to the inlet fuel line of the pump then check and make sure none are staying open.

Ron, why would a charge in spark power change the air fuel ratio. The amount of fuel required is dependent on the amount of air coming into the...
It would stay the same. The only thing that could change it would be if you had a misfire when using the MSD 8+ ignition. The only thing a hotter...
You correct in that there is Max rpm you can spin the rotors and then you loose efficiency at an alarming rate. It is different for a high helix...
Yea but with the autoshifter you will not zing the motor as hard if you blow the tires off because it will shift.
But would those bearings in a TF dragster be beat up because they can't take the 900 to 1000 HP push from each piston being slammed down the...
It was the ignition advance that was the cause of the increased power but the detonation was taking power away at the same time. This is why the...
A Roots blower creates lots of heat from the rotor seals rubbing against each other and against the case. As you progress through the run the...
Is this a frigging test? Hard photo to read but they look mixed. Down to the right looks close to being right but boy some of those look funny....
Yes, detonation is not optimum combustion so you will lose some power based on how much detonation in how many cylinders.
Why would you want to tune like that? If the bearing is smashed then you are detonating. Why not tune by reading the plugs. If you are detonating...
On pedal clutch a bronze floater is worth half a clutch disc. Mostly helps on the high gear lockup. Not sure about on a glide.
