Okay, I've read the sticky's, asked a few people via PM's, and now due to the variable answers am asking the public.

I'm looking for the easiest/most reliable/not most expensive fuel pump setup to support 1,000+ RWHP in my 1995 LT1 Camaro.

My setup:

Fully forged 383 LT1
84mm S400 turbo
115# injectors
93 octane, plus meth injection and a FMIC

I currently have dual Walbro 255lph pumps with a HOBBS switch to kick the second pump on at 4#'s of boost.

Some have said this setup "should" be capable of holding 1,000 at the tire. I would rather not push the limits and have some fuel pump to spare.

I have been told running dual Z06 style Walbro 400's would work, but I also researched they may not fit in an F-body (still looking for confirmation of this if anyone knows).

Ideally, I'd like to run twin pumps since that is what I already have for ease of operation and instillation, but am open to other suggestions.

What would you all reccomend and why?

Will two 340lph pumps do the trick?

For 1000rwhp, I would run twin 340s. I'm sure 255s could do and have done it but I wouldn't chance it for $3-400 more. Racetronix has a whole kit plug and play with their pumps in a bracket for a little over 400

I've seen their kit. It is very nice. But I honestly feel like I'd be spending unessisarily. The DIY bracket I made is fine, and unless my current wiring is not going to cut the extra juice needed for the new pumps, I just don't see a need in spending twice as much as I need to for the same results.

FWIW, I am currently running Racetronix 255lph pumps, and will likely run Racetronix 340 lph pumps if I can get a verification of what its max RWHP capability is.


Their website says 1400 HP. I am assuming this is at the flywheel? In theory this should equate to 1,050 RWHP using the 25% lost through the drive train rule. If that's the case, 50 RWHP is not much of a safety barrier. That 1,000 RWHP is a guesstimate. It may make more (I doubt 150 RWHP more) but I need to be sure I have a larger than 50 RWHP safety margin.
