RE: 400Lph max

For those running a single 400lph pump, how much power are you making? I'm currently getting the car tuned and it seems to be dropping off around 5500 rpm's. It's also being tuned on a Mustang Dyno, so I expect whp #'s to be lower, but taking that into account, I guess things would fall off faster. They're also using HP Tuners which did allow them to open things up a bit more.

I do have a KB BAP, but it's not connected to the 400lph tank..at least as far as I know. The shop that did the work couldn't really tell me one way or another. I also have 85 lb. injectors.

The T-trim is putting out 17-18 lbs. of boost.

Just a single 400lph pump in the tank with no return? What fuel? What's your injector duty cycle when it starts leaning out? Did you check and see if fuel pressure was dropping?

e85 or gasoline? Depends on your base pressure and AFR, but probably somewhere around the same time as your injectors are maxed which should be in the 1000 crank hp range.

Add that BAP, BAP+ Walbro 400 or 450lph is a poor mans 1000+whp fuel system its been proven to work.

Running pump gas, things dropping off around 5500 rpm's. I had to drop the car off. Tech called and gave me the info. Will try and get more info.

Gasoline, not sure of the base pressure.

That's what I'm thinking as well. Would be a good fix until my next round of upgrades this winter.

Thanks guys!
