Default Almost hit 600RWHP

Had my car dyno tuned today. Im running 8 1/2 #'s of boost on a D-1SC with 42lb injectors and a Walbro 340 in-tank pump. The injectors maxed out at 6100RPM. Thats when the air/fuel ratio started stepping towards the 12.8 mark.

586RWHP
534RWTQ

The RWHP was still climbing. So i will be installing an fuel pressure regulator and take the RPM to 6700 and then maybe i can hit the 600RWHP .

What size pulleys do you run? Is it on the stock bottom end?

I don't know, if you ran out of fuel that early do you think a FPR will get you to 6700 safely? Sounds like it's time to go with some larger injectors.

Try a Boost-A-Pump and/or wire the fuel pump direct to 14v.

Those are really good numbers.... With those 6.0 heads u can go 10psi with no problems. Im sure u can hit over 600rwhp. I thought the 42lbs were enough for 600rwhp?

they will make 600 hp but you will be well beyond 100 % duty cycle.
