I'm stumped, I hope you get it figed out. Car lookes sweet, I admire people that go big on the low buck. One ? though, when do the turbos come into boost? I was thinking of running a 6.5 turbo on my 95 S-10, the truck has the 195HP 4.3CPI. Right now it runs a high 15. Well any hoo, good luck.

 

What kind of injectors & what is your fuel pressure when it cuts out?

 

Had the same problem at 6100 rpm with a 1/4 of a turn preload from zero on my lifters. Reajusted them at 1/16 of a turn preload and gained 400 rpm ????

SVO 47#, pressure on the mechanical gauge is between 52-55 psi (starts at 43 and is on a 1 to 1 Aeromotive AFPR), A/F ratio is around 11, I have a digital A/F gauge and it is hard to get a quick glance sometimes..

I thought about trying a slightly looser lash, but it is the same stock lifters I ran before, adjusted the same way.

 

Thanks! Will be better if I can get to that higher RPM I want!!

Mine starts making boost pretty much right off idle, I see 7-8 psi at 1/4 throttle.

Last years dyno showed like 170 ft/lbs at 1800 rpm, 513 ft/lbs at 3400 rpm, so they work ok...
