LSA/LS9/L76 Powered G8 SleepingBoosty

That would have been my first bet. I hope you grabbled mls header gaskets! They are the best.

Glad you are rolling :tup:

Im hoping the samething happened to me at test and tune this last tuesday. After my 2nd pass, my car had a loud ticking lol. But i know my manifolds are warped so after i get them resurfaced i will find out if truely that is the noise. Although im 90% sure thats what it is since it sounded like a redneck pick up truck.

Pulls like a train…

nice numbers… what is your goal hp/tq? and what is next?

Goal was between 500-550hp at 9psi which is more than enough for a dd driven year round. I’ll probably keep it like this for a while and upgrade to much needed wider wheels/tires. I have the ATI damper so upgrading to more boost is cheap and easy should i get bored…

You should probably just leave it alone those 6l80es hate life over 600rwhp anyways.

I hear you on the tires… pretty good goals for a DD/AYR car. before my pontiac went under the knife it did 549/525 on a dynapack which is inflated.
after the operation it did 687/695 at new era. without tires in the back, it has its pucker moments.

Yeah prob the smart idea.
Anyone who thinks this much power in a DD is a bad idea needs to drive this car. You’d think it was completely stock until you really push it. Complete Jekyll and Hyde.
