shooting for 500awhp, I'm going to be running a rear mount, so I've been looking at a 70mm .81 A/R from magnum, 10psi should bring me close to 500 to the wheels, I'm looking for the quick spool, 10psi should be hitting a lil bit after 3k? i have 4.10's now on a 31.91in tire and ill be getting smaller ones that are 29.74in so whatever my gear ratio is? on a 2800 stall. this setup should be good for dd'ing?

 

Everything sounds good to me. I'm assuming your're running an LQ9. If that's the case, then you could prob go a little larger with the turbo and still have it spool quick. 4.10's with 30" tires and the 2800 stall will work great with your heavy *** truck.

 

ok thanks man, i was thinking maybe a 72 with a .81 A/R?

 

Yeah 72mm .81 will have a quick spool to it, and will leave you room to grow

 

T t t

 

I ran a Masterpower 76 qtrim on a rear mount with my LQ4 and it spooled decent. its been years ago so cant really give you much details.

Now my buddy that has a isky 212/114lsa 5.3 in a 98 rc has a 76mm qtrim magnum and it spools fast with a 4L80E / 3000 converter from a roll.
From a dig it does take a second to get goin but has a mean top end.

 

thats cool, I'm looking for the quick spool with my low gears i don't have much of a top end like 130-140 I'm wanting to get the most out of the awd but thanks for the info

 

The 4.10 will not load the turbo well and it will have more lag.

 

yeah but i need them, i got almost 6000lbs i gotta move, so maybe the smaller turbo 72mm and the smaller A/R .81 will help?

 

and it is a lQ9
