I Want More Power...

[SLED]

My setup as of this week will be

660 sard injectors

gt2871r 56T

Power fc

bosch 040

z32 afm

at the moment getting a very responsive 200.1rwkw on 8psi with no tune afr's are 10:1 across the board. Hoping for a responsive 240-250ish on 17psi with a fat torquey midrange.

i heard years ago FPR's can create an uneven spray from the injectors, can you shed some light simon?

10:1 Even at idle? If that's the case, you''ll definitely get your benchmark with a decent tune and a little more boost....please post the results when you get them.

Has anyone ever run a pair of these turbos on a GTR....I think they're the biggest you can go on low mount? If so, I'd be curious to know what sort of power you were getting and at what sacrifice down low. I almost considered using a pair of these on mine instead of the GT2860R -5 but wasn't prepared to sacrifice response.......I reckon they would of made 400 awkw easliy and without ridiculous amounts of boost.

i call BS on the un even spray... irs more or less due to the fact that a FPR change means that you have to retune it, cause the FPR is spraying more fuel in per given time on the injector... so the injector timing needs to be brought back.

yea thought it was bullshit, i kno what your sayin, the retune is because the injector pulse width is still the same but FPR is pushin more fuel in so the pulse width needs to be pulled back to compensate for the extra pressure yadda yadda yadda...

thanks

Yea mad rich across the board, i think idle is fine but its flat lined 10.1 AFR from 2k rpm onwards, lucky i got a daily otherwise it'd cost me a fortune. having said that its still very responsive on the foot, making 8psi by 2500rpm and pulls reasonably hard till around 6. Ill definetly post up results around next week, still deciding who to tune the PFC.

was that @ aussie dyno Ryan will you get Pete to tune your PFC

[Ryanrb25]

yea power runs were. pete and michael dont know how to tune yet...so no. i can get free dyno time so i was thinkin of getting jeff from speed lab or troy from mildrins to do it.

yeah i wondered that and was gunna see how cheap being a guinea pig would be and take someone down with RB knowledge

[nos man]

nice! this is very educational

[Ryanrb25]

i go there most days steve so ill ask for ya..they kno who you are anyways...hehe

[Madaz]

yeah im thinking of going again for power tune just upping the boost from 9-10 to 14, before the sau dyno day

[Ryanrb25]

go have a look at what we did with michaels R31.. rebuild rb20 with aries forgies, freshened block and head, GT3540 with a 1.06 rear with a dump pipe michael and i made, microtec, 600cc injectors, lag monster.... i wired it in using half ceffy, VL and R31 loom. lol
