Spoke to shumby this evening, He made it safe and sound, this crazy MoFo drove 2300 miles straight home .Here is the final pics of the project with the dyno results, also i'm including some generic pics of a the Camp II HKs system, shumby had us install every sensors available for system(fuel, oil temp,oil press,boost, egt )plus all the info we get from the can bus .

I was really hoping that it would push above 400hp. Does these have the lth?

For 6 psi 7 A/T @ 91 OCT these are exponential results . couple more psi and the set up can do well over the 400 mark.

....long tube headers??

No, stock headers and Stock cats .

Sam

You dont prefer the headers on the car?

Headers have very little back pressure and the VQ engine requires a certain amount of overlap in valave timing. With the lth there is not enough back pressure while trying to maintain the correct/ideal valve timing. Sam correct me if I am wrong here but tht is my understanding why lth are not ideal for any SC setup and this engine.

Just want to know before I actually pay for my headers.

With the LTH and VVEL there was not enough back pressure with so much valve overlap to build much boost. I think they said the S/C would only build 4 psi with LTH and CBE.

Sam, I still don't understand why the shop car made 8psi + 450whp and Shumby car is only at 6 psi + 390whp. Is it the CBE or just the tune?

is there a reason for only 6 psi? I thought the kits were suppose to run 8 psi.

All that power with stock cats. That is insane on an auto. Very nice GTM!

Congrats Shumby. :tup:

Looks good even for a G....:stirthepot:

yall have to remember he has an AUTO transmission and the shop car is manual. The auto transmission will not make as much RWHP. Effectively if he had a manual G it would of been over 400rwhp @ 6psi!!! that is freakin nuts!

I am impressed with the Tq at such low boost on an AT. Great Job Sam
