Man that looks good.... Makes me wanna G8 GT

 

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..

 

*L92 heads....

 

Yeah that's awesome can't wait to see the dyno numbers to see if it hit 500 RWHP with those three additional parts. Makes me think about getting a G8 for a family car with some kick!

 

wow, that is a beautiful car

 

Hey guys,the numbers for the g8 are up,pretty good results.The supercharger kit was from Harrop in austrailia.The headers and exhaust were built in house by me.

 

I have a video clip of a dyno pull,i'll try to have it up soon.

 

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.

 

9psi, not too shabby. Any other options for intercoolers ?? How much power do you think a meth kit would yield ??

 

thats pretty sweet...

 

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

 

Thanks.

 

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.

 

not bad, not bad at all

 

very very very nice!

 

had just over 1000 miles on it

 

looks a lot like the maggie's and im sure you know just as well as others that the iat's are always rediculously high with those.

Im asumming there was custom tuning involved?

All in all the craftsmanship looks amazing!

 

Shawn,

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!

 

Love it!! White Hot is deffinatly the color i'd get if I got one. Real clean looking n a roots blower. Sweet!!!!!!!!!!!!
