Nice. Thats enough mph for 8.60's when you get the front half figured out. Great mph.

dudeman 11-17-2012 11:43 AM

thanks! i think i can get it sorted out. this was the first time out with a new rear suspension setup. need to get the stupid 90/10 shocks off the front and replace them with an adjustable shock.

the gt91 is a budget $1300 turbo from forced inductions. I ran their gt-88 for a couple years then upgraded. They are a pretty nice piece

Wow....that is amazing! What fuel you running? E85? I am curious what others think about your cam choice. I run a pretty good size cam also. Seems that everyone always wants to run a "smaller" cam on the turbo's but yours seems to love the bigger cam. I would love to hear a video of it just idling in the driveway if you have any.

Do you have any pictures of the set up? How are you running the exhaust? Also, are you using Hptuners, stock pcm, stock wiring harness?

it does use e85. its is on the stock harness and ls1 pcm. the motor is a 2007 with a 58x reluctor wheel so i use the lingenfelter converter box and its tuned with hp tuners.

no idle vids.

the exhaust is shorty truck headers flipped with v bands welded on. 2.5
cross over. 5" dp split into two 3" pipes that run back through the k-member to the firewall and then turn down.

Sounds like the EPP blower cam

9sectruck 11-17-2012 08:39 PM

that cam has 6deg of overlap in it is there any back pressure issues with that cam?
what did you torque the head studs down to, I have used the ebay studs up to 22psi of boost on my built ls2, but im pretty sure they where torqued to 75ft, what did you do?
