Not Ranked
That's a great improvement. I knew you'd pick up lots of power when you turned the motor over to KC.
What kind of chassis dyno was it? If it was a Dynojet, then 406 rwhp will give you about 450 at the motor. On a car like yours, it's about a 10% drivetrain loss. Lots of people have their opinions on drivetrain loss numbers, but being both an engine builder and chaissis dyno owner, I have seen first hand what the actual losses are. "My" loss numbers are as follows... manual with live axle- 10%, manual with IRS - 12%, auto with live axle -15%, auto with IRS - 18%. Cobra side exhaust also kills a ton of power because the mufflers are so restrictve to keep noise down, so be glad you have a full exhuast system.
