OEM TT fuel pump capabilities
I currently utilize a 3rd gen RX-7 TT fuel pump in my Turbo Galant. I'm finding that I'm getting knock when I'm maxed out on my fuel correction. I was curious how far your guys have modded your cars while still using the stock TT fuel pump?
Thanks, in advance for your input.

It was one of the mods I did when I did the full exhaust and the ecu upgrade. In terms of whp I would go with what Goodfellasfd3s said. Anything over that you are risking running lean.

.50 trim T3/T4 .63 a/r on the hot side, Ross 8.5:1 pistons, crower rods, knife edged crank, 720's, S-AFC, VPC with 660 chip, VRS stainless 3" Downpipe, Borla XR-1 muffler, RX7 TT fuel pump, Stage 3 cylinder head from BJ's cylinder head, crower spring kit, 1mm oversized ferrea valves, ARP head and main studs, rear mounted Red Top Optima, MSD DIS-2, Aeromotive FPR and B&M gauge, ACT2600, Galant VR-4 trans with Shep racing rebuild and 4 spider gear center diff
A list of my main modifications. With the car tuned, it should put out more than 300 whp easily. Possibly close to 400. I'm having problems going lean, over 5k rpm. I suspect the fuel pump as a possibility

No, I know. It's really not comparable. I used to have a 13b 1g. Didn't last, though. I was just trying to get an idea of how much they drink, by comparison.

this site has some info regarding flow rates of various pumps including the RX-7

btw I hit 321 rwhp at around 86% injector duty cycles with stock pump and injectors...approx 13 psi
