Since last time we dynoed only 400 rwhp and 460 rwtq with our restrictive LS6/stock throttle body, we decided to go all out on our intake setup. We ordered a GMPP carb intake and had it modified for EFI and ported for the Strictly Performance Motorsports heads, this thing looks better than pictures. We also got a 100 degree Wilson Manifolds 90mm elbow (modified to match the ported GMPP intake) to bolt up an Accufab 90mm 5.0L throttle body. After adjusting the injector table for the new 40lbs/hr injectors, we made our first pull. Ken of HPTuners started to dail in the AFR, after a couple of passes, we were happy with the results. We dynoed 451.2 rwhp @ 6220 rpms and 508.6 rwtq @ 3445 rpms! This is still on a 1998 stock short block (block, pistons, crank, rods) with about 90K miles. I should definately be in the 10s now! We are going out to our local race track (high elevation: 3500' DA) so I can get used to the new found power. Then on Thursday it is Super Chevy Show time and I should run even better numbers out there.

I will post up picture of our new intake system later ...

A HUGE Thank You goes out to Rob Barth of Strictly Performance Motorsports and Ken Cannata of HPTuners for their (above and beyond) help on this project! Thank you very much guys!

 

WOW! Serious gains! More details and pics of the intake!!!

 

Here are the pictures of our new intake setup, as promised! Excuse the mess, I am going to get that intake tube painted black.

 

That is wicked!
