What do you guys think? I want 550hp at least like to be around 575hp. I don't tow at all, its a DD, and I don't want to lose to much spool up. I will add a HRVP sometime in the future when the SO craps out and MAYBE a small shot.
 
How is your daily driving with the 64/71/14. What size injectors you guys running with them. What rpms do they light at.
 
I run Mach 6 injectors with my 64/71/14, laid down 575/1057 on fuel w/nitrous it went 681/1224.
 
Cummin724 how much boost are you making. What is your hp. If you don't mind me askin. I think I am leaning towards the 62/71/14.

When I first got it, I was seeing 55psi boost with the Drag/Smarty stack. I adjusted the wastegate for 45lbs & it never went over that with the stack. I switched to the Adrenaline & am now seeing 50-52lbs boost again & I haven't touched the wastegate. I haven't dynoed my truck recently, but I made 476hp/936lbft. with these injectors, A HTB2 62/65/12, Holley blue, Edge comp, running 40psi boost. Since then, I have added a Airdog, Super Stock 62/71/14, Studs/orings, 1/2" lines/draw straw, HTT 3 piece manifold, AFE Stage 2, Dual Disc, Fluidamper, Adrenaline/Smarty. I should be around 525hp or so. This turbo is awesome, but I think 575hp would be mighty toasty. I'd get a Silver 62.
 
Skip the HRVP and put your money towards the turbo. I love my 62/71/13ss. It spools great even with my auto and I daily drive 700+ miles. Heck, I just put 550 miles on it between friday and saturday and it never missed a beat. I love this dang turbo.

There's a lot of things I like about it and a lot of things I don't. On the plus side is it dyno'd 542 hp with no egt issues (H2 cam helps) and doesn't choke out easily, on the negative side it doesn't spool any sooner in the rpms than my old 64 and makes more smoke both off the line and during accelleration.
