LPFP needed with meth kit?

Schmidty335i · 10-16-2014, 02:21 PM

my N55 is FBO with a pure stage 1 turbo i am wanting to make sure that it is getting all the fuel it needs. i just ordered a BMS meth kit this morning and was wondering if my stock LPFP and a meth kit, will it be enough to cover what ever the pure turbo can throw at it? or if i need to upgrade my fuel pump aka inline. thanks for any input!

Depends on how much E85 you want to run. If you are E30 or under, then you should be good to go without any help.

E30 and meth should be good for about 420 whp with my setup right? (i have the MT also) i think ill just wait till i get my meth kit and see how i feel then if i need more power ill upgrade the pump and run more E85.

You know it's not an "if...just a "when"

I think you'd be OK without it, since the meth is basically additional fuel. N54 guys are running basically the same power if not more than a pure stg 1 on the stock turbos and stock lpfp. For what it costs, I'd do it for peace of mind though.

I have been running pure stage1 and meth kit on max boost just fine. I can run 30% e85 just fine on stock lpfp. Anything over that requires a lpfp upgrade on my car. I can do 40% but sometimes it stutters. So i ordered lpfp upgrade now

Get logs and you will know if you need a lpfp or not

Go with a proper LPFP setup. I never recommend using methanol as a fueling band-aid.

+1... But if he's not running anything higher than e30 just pull a log and see if the stock is happy
