So... forgive me if I missed it, but where'd the supercharger come from? I've been waiting to read up on Eaton kits (or any roots or screw-type blower setups) for vehicles with L76 heads..

453 / 443 with a car thats just broke in, and IAT's thru the roof. Oh yeah headers and 3inch exhaust. I'd say she did pretty good. Over 400 rwtq at 3600 rpms. NICE !!
What would you say the reason for the high IAT's were ?? I am sure that she will do better on the street with plenty of air flowing across the intercooler.
Good job Shawn !!! Last question, how much boost to make those numbers ??

Thanks,the iat's were high due to a couple of resons,1 it was extrememly hot and humid during tuning-iat's were the same on the street at 3am that morning.2,the intercooler isnt quite effiecient enought for that s/c,a meth kit would have greatly helped,but the cust didnt want something he had to fill.Those #'s were at 9psi boost.

the intercooler core was built into the manifold,a bigger heat exchanger in frt of the rad might help,the meth kit would help alot considering it was pulling a ton of timing,total timnig was down as low as 9 degrees.easily 20hp,probably more

Thats a very nice G8. How many miles were on it when it was put on the dyno? It should put down some better #s after a few months of being broken in.

Had a dashawk thrown on the car during the drive down south. It showed the car IAT dropping as low as 124 - 126 degrees. It ran solid the whole way to Texas and back. Electric fans kick in at 217 degrees. Oil pressure stayed around 41 - 53 psi.
Brian got the tune reloaded the other night in about 3 minutes. Car is excellent. Here is my email address will you pass it to Brian so I can get the tune from him.

Amazing job on the car. Can't say enough about all the effort you all put into it. Thanks for everything!
