Thinking about a boost a pump

[99VERT]

So, after my last Dyno session I put down 705 to the rear wheels on his first pull. The tuner said I was getting close to running out of injector and we stopped right there. I’m running stock fuel system stock injectors on 93 octane. Should I look at doing a booster pump? The only extra additions I’m thinking of would be a BPS elbow & larger mono blade. Need some guidance.

I would run one. My goal was around 700-750hp and I went with 1050x injectors and JMS booster. Overkill, but didnt want to run out of fuel.

Great numbers. Definitely get a BAP. What was your fuel pump duty cycle at on the run?

Also, that’s a lot of boost on 93. Something to think about. If you don’t have long tubes, might be a good choice to bring that boost down a bit and put down some more power.

Not a 100 percent sure but I believe it was in the low 90% on the duty cycle. I have long tubes on there & the Dyno graph is a little deceiving. The boost dropped by a pound and a half with the longtubes and I usually see about 16.5 throughout the run. It spiked to 18 1/2 right at shut down.

Copy that. If that’s the case, sounds like you need bigger injectors and a BAP if you’re wanting to go up from there.

I'd consider long term goals for the car. If you plan to run e85 @ anytime in the near future make sure you choose your injectors with that in mind. I'm currently @ 750rwhp, I added the KB plug & play BAP for now and held off on injectors because I plan on building the motor, adding cams and a return style fuel system down the road. My current set up is Gen II TVS, 2.5 upper, JLT 127, FRPP Mono TB, ARH 1 7/8 headers w/ high flow catted H, stock injectors, KB competion BAP and a Lund remote tune.

Same boat as you. Im looking at the JMS BAP and would also like to add Long tubes.

Im at the power level I want, just want to ensure Im safe on fuel.

My '13 pulled 716rw @ 16.5psi boost with headers thru 410's running the KB Mono blade + O-Sized plenum. Running stock '13 injectors. 93 octane. Using Lund tune and Lund viewed the WOT redline data logs advising no need for BAP. I forget where he said I was on % pump output. The dyno shop where I did the test pulls did not feel the need for BAP. If I did any more upgrades I'd just buy the BAP without question.

I don't think you need BAP unless looking for more power.

Ok good deal. I also forgot that the 4.10s lower the horsepower figures.

 

[biminiLX]

I always forget that. My car has only been dynoed with 4.10s
