any guess at my power gain??
 

last dyno was 303 whp at 10 psi on pump gas (94 octane)...I'm getting my fuel upgrades... 1600cc secondaries, walbro pump, custom fuel rail, rising rate fpr....any guess at what power gains i might get? mods are below...OH....for some unknown reason, I'm actually now getting 15-16 psi on a regular basis...not sure why...so I've been running race fuel to be safe...I have 50% more boost than I did for my last dyno....any guess as to how much whp either that extra boost and/or my fuel upgrades will give me?
Thanks

air intake, hks dp, full exhaust, streetport, Haltech E6K.. 303whp at 10 psi, pump gas

Your not going to get power gains from adding bigger injectors or a fuel pump, what gives you the gains is those things allowing you to re-tune your car for higher psi or what not if you didnt have enough fuel to turn up the boost previously..so id get your car re-tuned, especially if your planning on always running on race gas..

yes definately....i know what you're saying and that was in my mind...im improving fuel delivery IN ORDER to get more boost, which is what makes more power, yes...so really I shouldn't be asking it like that about my fuel upgrades...more like, with my mods, going suddenly from 10psi to 15-16, which it seems to be performing well with.... can anyone even ballpark.....just for interest sake, really....it will definately be retuned on the dyno....ive just been excited about the noticeable increase in power....it feels quite significant....

303RWHP is insanely impressive for "stock boost".

Thanks!! I was thrilled myself. Brand new streetported engine from Tuning Factory in Farmington Hills MI (Detroit..)...that was 10psi PUMP gas...me and the guys at the shop were happy that's for sure....

You'll get 1 million extra horsepower from these mods.

Oh thanks. See, my calculations told me I'd have 876 839 extra HP, so thanks for clearing the air.

PS BMW is absolute crap. Big, fat, heavy, ugly cars. I've driven a few and they're overpriced junk.

i hate these fucking questions. dude....look around and see what people are making and compare your setup to theirs.
