Whatever you do don't get STS turbo systems heard bad things about water messing them up

 

Alright since ur new y not tell us the vehicle this is going it. What trans and converrter combo ru running. What cam ru running to get those NA numbers with stock 862 heads? Is this a daily, street, or drag only vehicle. A damm 88 will make a **** load of power at 7000 rpms. But that dam thing is going to have insane turbo lag lol.

 

going in a 09 crew cab cheyenne. stock converter and 4l60E for now. Stock heads. Want to have the most hp possible on the stock block for now and have it as a daily driver. Going to change my stall but dont know which one to go with 3k or 3200.

 

You do realize that 340 to the wheels is over 415 crank hp??? And your doing this with cam, headers, a tune.. .. Don't want to **** in your hat, but that is almost unbelievable..

 

yeah. when it was done getting dyno tuned they thought it was a 5.3.

 

Im sorry man but that dyno must have been off. I dynoed 355whp with boltons no cam and tuned with a 60shot of nitrous on my 5.3

 

Trust me I belive it my cusins 2010 4.8L crewcab Sierra Dynoed 344rwhp with SPEEDTEKs cam package he's running strong for a lil 4.8L whopping 6.0s and 6.2s from 30rolls we even dynoed it at a different speed shop and the 2nd time he dynoed 339.8 rwhp like 3 months after the install

 

Being an '09, his 4.8 should have 799 heads, higher compression, and the GMT900 intake, right?
