Default 60lb or 80lb

Which one will I need to handle 800rwhp? Also will a 450 bosch support those injectors?

60's will not support 800 to the tire on pump gas without running a ridiculous p/w. I know for a fact it's possible with a fuel that supports a higher resistance to detonation but not dinosour ****.

also think about if you want a converter box or not... If you're on the stock pcm and don't want a converter box then 60's are what you have to work with... You also think about some meth..

also, what size engine is this on?? If it's on a 346 you're going to have to push the **** out of it but if it's on a larger engine you can make more power on pump gas...

You can get nice, plug n' play (no box needed) 72# ones from RC Engineering. I'm using them and they will get you well into the 800's.

60lb mototrons have supported 800+rwhp in a number of Vette applications. At 85psi f/p, the are equivalent to 80lb or so injectors...

I think the bosch 044 pump only flows enough to about 680 flywheel hp. Maybe with a voltage converter or BAP at 18 VDC then possibly it could get you to 800 flywheel if you're lucky. Dual pumps for the win in your situation.
