I plan on this combo eventually:

AFE satge 1
4 inch exhaust
Bell USB 62mm turbo
HRVP44
Mach 6s
Drag Comp
Studs

What kind of power am I lookin at?

 

That turbo is going to be to small for those injectors. Your going to need at minimum a 66 to support that kind of fuel. Twins would be your best bet for those injectors. Other than that your probably staring 600-650hp in the eye.

 

I don't know jack about the bell usb turbos, but assumming its comperable to a phatshaft or htb2 I'd guess 550. I'm thinking you're short on air with that much fuel. Sps66 should take that combo to 600.

Stealing from some of Don M's posts:

 

You beat me to it cuz I was searching through Don's posts for injector recommendations

 

guy at the track one night had this same set-up but with smaller mach 4's...this truck was an ext cab short bed, 6" lift, on 37" tires running 13.6's

id say its right around 500/1000

 

You need a larger turbo for this combination.... Something in the 66mm size will be warranted. Also You don't need both the HRVP and Mach 6's. Test are showing that Mach 4 - Mach 5 are showing max HP with a HRVP. So you can save some cash by going with a HRVP and Mach 4's or a OEM pump and using Mach 6's.

If we can answer any more questions please feel free to call.

Are mach 6s and an HRVP44 to much fuel?

 

No. It's just that the HR maxes out sooner with smaller injectors because it puts out more fuel and doesn't need a super large injector to make the same power. Both pumps max out at about 650hp or so.
