Quik's Turbo'd silverado making 698rwhp on dyno- Video



truck still had plenty left but was limited to the 5psi wastegate spring. so it was fluttering at 16psi.. this was basically right off the street tune. only changes 3* timing added and 8% fuel removed past 6k

 

Nice, deff a very nice truck! I watched the video/slideshow that was on the build thread.

Its a 88mm right?

Jay

 

yes a precision 88mm only on 16psi

 

what kinda compression?

Jay

 

8.8 i used 241s to drop CR down

 

Looking good, I would have never doubted that. If you keep it from detonating you will find the limit of the rods soon enough, with that kind of rpm. Get any closer to 825 and we will have to take the little 74 off the GTO lol.

 

i would like the dick sized numbers but with my money situation right now i cant afford this truck to be broke. maybe when things change ill step it up some

 

is this on stock bottom end? or what pistons and rods are u using if not stock? what other preparation was done to the bottom end? head studs?
very impressive
also what trans and tc?

 

stock rods, stock pistons, stock bearings, stock mains. only thing touched on bottomend was rod bolts. only has 11k on it. built as general did. stock untouched 241 heads, TTY head bolts, MLS gaskets

viper spec'd T56 with ram VDS clutch and a 9.5" 14 bolt rear with 488s

 

im thinking of rebuilding a 4.8 with 5.3 dished pistons and using some 241 or 243 heads. also for a budget turbo build.
did u know, speed pro has replacement pistons for around 400$ with rings. they come with grafal coated skirts.
i have used these 6.0 pistons in a 6.0 rebuilds with my own dd and puttin down just under 500rwhp, with some 5.3 stg 2 heads
they go up to .060 over and are available in 4.8 with flat tops and the 5.3 with dish. 6.0 are also 8cc dish

 

cool, i dont plan to rebuld this motor if it dies. the plan is use this block for my camaro or if i can find another iron block save this motor for something else

 

nice numbers

 

wow.. those are truly nice numbers.


aaron

 

WOW man, that thing will fly!!!! great numbers

 

badass!!!!!

 

Nice, safe tune, easy power and more on the table

 

Quik, what injectors are you running and what is the fuel pressure?

 

base is 58 and motron 60s. 101% duty cycle at 7300 rpms

 

from the graph, it doesnt look as laggy as I would expect.

this makes me rethink the 76mm for my 283.

 

damn, now maybe i know what to do if my LT1 ever dies
