Proven 500+hp combos for H.O.'s ??????

You have some choices on fuel:
1) The HRVP44 with the injectors you have should do 500 or real close.
2) M4.5's and keep the pump you have will make 500. Ultra driveable!
3) M4 or 4.5 and the HRVP44 and you will make 565-580. No Joke. I had a customer make 604HP with a HRVP44 and M4's. He had a PS66 turbo.
If you want to keep the turbo you have, the HRVP44 with M5's will crack 530 with ease, but will run hot on high box settings.

well i have a adkins lil 55 headed my way very soon, and my comp will be getting upgraded to a drag version by the end of the month.
im also preparing to swap out my injectors for some 150hp units so i should be just shy of 500hp by the time the spring dyno day rolls around for the MDTDC...gonna be a fun day for sure.

Read through this one again and noticed a few of you were waiting to dyno again, anybody have recent dyno results? Looks like i'll be going with injectors from DonM in the Mach 4.5-4.9 range. I still need to talk to him about it though. I would like to crack 500hp without getting a HRVP44. Dyno days are coming up around here, gotta get movin!
I need to find 66 horsepower to get there!
