John,
     I was making 14 psi of boost from 3000 rpm up. I had to install two=20
waste gates to keep from over boosting. The numbers pretty much fit what=20
was happening in real life. They said that with 14 psi of boost this=20
engine should make twice as much torque and HP as a stock engine and=20
that is what was going on with one really big difference. The torque=20
curve did not start to fall off until the engine reached 11K+ rpm. The=20
stock engine was starting to loose torque at 6500 rpm. This meant that=20
the breathing wasn't falling off until the engine was above 11K rpm.
     This gave a HP curve that was a straight line from 3K rpm to over=20
11K+ rpm. So at 10,400 the engine was making 500 HP. Part of this was=20
due to the turbo force feeding the engine and part of it was due to the=20
porting. The bridge porting increased the over lap from about zero=20
degrees to about 25 degrees. It wouldn't idle below 1100 rpm and it had=20
a decided lope at anything below 1600 rpm.
     The best idle speed was about 1300 rpm. Below 2000 there was very=20
little torque but hang on when the rpm got to 3000. With the big tires=20
and the traction bars it would lift the front tires completely off the=20
ground. If you punched it in 1st gear on a curve you were in trouble=20
because it would immediately straighten out.
     Like I said it was a lot of fun but it would kill you in a heart=20
beat if you got stupid with it. I had a friend volunteer to drive it as=20
fast as it would go. I wouldn't let him drive it at all. I was afraid=20
that he would kill himself in it.
Thanks,
rich!
