Well we ended up making 1070hp to the wheels through a TH400 transmission. The problem now is that we are having a hell of a time finding a torque converter that will allow us to stall at 5500. So now it looks like we will need to throw a 225 shot of nitrous at it to get it to launch...

A/F was fine as we have logged every pass that was made with the car whether it be on the dyno, or track.

You have to multiply .65 by Methanol's stoich A/F ratio which is 6.4 .65*6.4 = 4.16 You are thinking of gasoline's stoich A/F ratio. What I really need to know is what type of additional timing we can add with the methanol vs. Gasoline. Is there a rule of thumb like: with methanol you can add...

We are waiting to get the car back before we can tear into the engine, as it is currently getting a new intercooler installed. We definately are not experiencing a lean condition as our datalogs showed that we were tuned at about 0.65 lambda. This is a turbocharged car. For reference we also...

We are running the stock Toyota head gasket, but I am aware of other people that are running the same gasket on methanol with no problems. The head studs are stock sized (7/16" I believe) but were upgraded to ARPs L19 material. The timing was about 6 degrees advanced at 40 psi and 8500 RPM...

My company has recently built a drag car that uses methanol fueling and high boost pressure. We are having some problems with burning through the head gasket, which I believe is due to an over conservative timing map. Some info on the engine are: 3 liter of displacement (Toyota 2JZGTE), 40+ psi...

I currently have a turbocharged 6 cylinder methabol race car that I am having problems with pre-ignition on. We have seen instances where the engine will pre-ignite and cause the head gasket to be damaged between cylinders. Does anyone know an effective way to combat pre-igntion? Also, could the...
