My VGT setup.

Postby huntinguy » Wed Jun 22, 2011 7:41 pm

I posted this on CF but I know some of you arn't on there so I figured I'd let you see it too.

I think I have it dialed in pretty good right now. lights almost right away, makes 45psi. Mods are, ground fuel pin. pump almost maxed,(unknown injectors) procomp lift pump, timing to the head and 4" exaust.
With this turbo I hit 1700* at 85mph in 4th gear. before the turbo and the timing I could hit 2100* in 4th gear. :oops: A few more mod's are in order but I'm getting closer. :D

If you didn't know this is a he351vgt. I'm useing drive presure to open the turbo, a spring to close it and boost to balance it out. I have a filter and a needle valve on the drive presure line.

Nice. I have pretty much the same setup but a 60mm H1C. I can hit 1800 with stock injectors. Before the turbo I could hit 2100 with a 1/8 inch timing bump.

Looks Good but you need a bigger filter

Doubt it. They looked fine when i pulled the head. Just need to hook up the intercooler sitting in my grille doing nothing.

Update!
This truck is now intercooled and cranked up a little more. It did 15.853 in the 1/4 mile this summer with 33's and a bad boost leak.
This fall it put down 346hp on 35's with a minor boost leak.
This dyno didn't have a brake and my rear brakes were out so the number is a little low.

Looking a little less ugly these days.

Minor subject change... Did you keep your A/C condensor with that intercooler? If so how?
