25 psi?
? did you have to do anything else for the motor to handle that much boost? what did it run prior to the turbo?
Inside motor, no. Out side motor, yes. Fuel enrichment tricks, hotter ign, stronger clutch, adjust rod on turbo to get boost from 5 psi to 25 psi and run the best gas I could buy (116 octane). Mind you best times were short shifting at 4500 rpm. and 110 mph in 5th through the lights.
Always wanted to build a special motor, but never got a round tuit.
There are some links on the board somewere to videos of it up against Mustangs, a 66 GTO with a big block and a noisy Mazda RX7. None of them could keep up.
