408 CID Twin turbo build
Car is a 2000 SS 6 speed. Mods are a 30 spline (viper) T-56, Moser 35 spline 9" rear narrowed 3" per side, 408 CI forged iron block, Pat G cam. Tripple 255s in -tank, 80lb injectors, LS-6 intake. The turbo kit was made by 417 Motorsports in Springfield, MO and are twin 61mm T3 flanged turbos, (kit was originally owned by fitz98ta)...A bit small for this motor, but the spool should be WICKED. Going for 14-15 PSI on E-85 and around 800rwhp or whenever I run out of fuel system. I'll keep you posted and add videos when we get it running. Heres a vid running 14.2 psi with the fuel pumps dropping out. Did 0-115 in just over 8 seconds on the street taking it easy in 1st gear! http://youtu.be/lipMltJpJ-U

I just saw this post man.
Glad the car is turning out good. Someone needed to keep that kit alive!!!
Plugs aren't near as bad as they used to be to change. When a couple added v bands were welded in, it made a world of difference. also with the k member it will help too.
I can't wait to see how much power this kit will make. I only got it up to 14 psi w/ 12 degree timing and it made 755 rwhp on a non-brake dyno.

I finally installed tripple in-tank pumps and that solved the fuel pressure issue. Next thing I did was turn the boost up to 18.1 and got in 2 small street pulls with the 2nd pull ending right when I hit 3rd gear. The T-56 made a loud pop/gear breaking noise and then I'll I had was 4th gear. Got home to find the input and counter-shaft gear teeth were all sheared off. The splines on the input shaft were also starting to twist where the clutch disks were located.
