Whipple 2.3L Fuel/MAF Questions

[LAK3RS]

Putting down no more than 400-450rwhp with a Whipple 2.3L, I know that 39lb injectors and an SCT BA-2400 are perfectly fine to run. My questions are if I can install 60lb injectors and up to a BA-5000 and there not be any issues with the tuning? For instance, is it more difficult to tune for 400-450 using injectors and a MAF that are both bigger than actually needed? Using the 60's and bigger MAF will give me plenty of room to grow in the future. Also, the MAF housing that comes with the Whipple is 95mm. Is there any reason to ever swap out the housing itself for bigger one? Last question, I promise! Regarding the BA-2400 MAF, do I need any type of adapter to make the BA-2400 work with the Whipple MAF? I'm assuming that it will just slide into place and the stock connector will hook up to it.

Honestly, my guess is that I'll be perfectly fine from 400-600rwhp with both the 60's and the BA-2400, but I just want to make sure.

Do you have a custom setup right now?

No sir.

I can share some experience from my Whipple. First of all the injectors are 32lbs at Ford delta pressure of 39.15 lbs, 34 at 3 bar (43.5) and finally Bosch rates them at 38 lbs with 3.5 bar of pressure IIRC. The standard Whipple kit uses the stock maf. I was able to get to 488rwhp before both the maf and injectors were maxed.

Remember that a 3v Whipple uses Ev-14 length injectors, same as a gt500. I went with gt500 injectors which are rated at 47 lbs and an hpx pmas maf (same as ba5000). Some tuners don't know how to make gt500 injectors work so ask your tuner if you decide to use them. They can usually be picked up for $125 or so used and brand new for $220 from Tousley Ford.

The last injectors I used were new gt500 but modified for more flow, flow matched ev-14 length 80's. These were the best injectors I've ever had. They were $450 from www.corvetteinjectors.com Needed them for E85. They worked great with gasoline and 15 psi too. Once again if you decide to go this route ask your tuner first.

To answer the question as long as you have the right components and tuner injector and maf size aren't going to matter too much.

Thank you. Regarding the GT500 injector tuning issues; doesn't it have something to do with the spray patter of them?

Here's the pattern. Keep in mind a 3v has two intake valves on the bottom same as a 4v.

Here's a video of 39lb Cobra injectors. Same spray pattern yet nobody has problems with them in the Ford world.
