Need More HP must go faster!!

[skaterfromvt]

Hi everyone i was just working on my car and realized i didnt have anything else i wanted to do to it...so i need some ideas on what i can work on next!

So far its an sr20det stock internals and a few bolt ons...ecu tuned running 15lbs of boost dynod at

261 horse and 296 ftlbs of torqeran a 13.6 at the track with clutch slipping and my balled drift tires..lol

what should i do next that wont effect my ecu tune...that will free up power? or make more power

Thanks for all the help guys

[idahotuner]

are you serious.... you did all that and got that much out of the t25 and you dodnt know what to do next.

[skaterfromvt]

haha yea...im thinking lightend pullys maybe intercooler sprayer not sure exactly...i mean im happy with it i just gotta keep moding it cuz theres always some1 out there trying to beat me! u know...

btw is 261wheel horse and 296ftlbs pretty good on stock mas stock injectors stock turbo?

[idahotuner]

well hate to break it to you but you will not be able to get anymore wih out havina tune done. its not pissible. in fact your on the edge of hurting your engine as it is.

[Koshin]

yeah man youre wringing that t25's neck man....AAHHH turbo, injectors, MAF, tune

BTW, when the turbo breaks it gives you mad horsepoweralso, change your blinker fluidh wile you're in there

[Taylor008]

OUCH. 15psi on stock turbo AND injectors?! Injectors max out at around 11psi.

I don't get your question though. Get a 2871r, maf, injectors, cams, intake, and exhaust and your good for +-400hp.

[Tulsa_S-13]

OUCH. 15psi on stock turbo AND injectors?! Injectors max out at around 11psi.

Wrong.

I've seen many S14 SRs running north of the 250rwhp mark on stock injectors, 370cc without any problems on nothing but a Walbro pump.

100% duty cycle at 11psi? I don't think so. At 11psi it's time for an intercooler upgrade. I run my T25 at 13psi no problems. I do suggest getting on a wideband though to see where you're at A/F wise. At 15psi you're past the T25s efficiency and with the numbers you're posting I would imagine when they dyno'd your car they set it up on a wideband, no?

[idahotuner]

no you can run 14 sppsi on stock injectors it just isnt recomended for long peroids of time

[Emperor_Tha]

s13 stock maf dont compensate well after 12-14 and start to lean out. With a safc atleast you can solve that lean issue. But if u have a 300zx on safc neo u are safe even with a 0 correction point u be at 10.6 at 13 psi

I thought the injectors maxed out at 11psi. My bad lol, long day.

Annnd I thought he was talking about a T25, not a s14 T28.

[idahotuner]

he didnt say whihc turbo but with either one the fuel syustem will max out at the same horse power range.

[driftset]

dynosheet... please

[skaterfromvt]

the dyno sheet has sceene better days its been in the glove box and showed off alot but ill try and get it uploaded later tonight! um yea i was under the inpression that the turbo i had was a t28 but like i said im new to nico ive only been into building for about a year now...

and the i do have a walbro fuel pump and a pretty large intercooler...

The tune was done with a wideband of course...i wouldnt risk running that set up with out one...

and i am aware that this turbo will probally become inaficient in about a year or so...but it will be a fun year

I just figured id post and see what the fellow nico's had for ideas...im gonna Heat wrap the exhaust mani later and hot pipes and probally put pullys on...after that Im out of ideas....

THanks again guys ill get that dyno sheet up

The guys that did the tune for me are... Best1tuning.com their really good at what they do! they can even repair fried ecu's The Guys Name is hunna

[idahotuner]

very nice dyno sheet. now get on some fuel upgrades.

[S14toRPS13]

Nice numbers! I agree with everyone else though. Fuel upgrade next. Also, what was your trap in the 1/4 mile?

[skaterfromvt]

ON THE 1/4 I BELIEVE IT WAS A 13.61 AT 106 MPH

WHEN U SAY FUEL UPGRADES WHAT EXACTLY ARE U SUGGESTING?

THANKS! BEST1TUNING.COM GOT THE JOB DONE

[idahotuner]

well starters. i am guessing you al lready have a walboro 255 fuel pump. then you would want z32 fuel filter. and then you would want larger injectors. some where in the 550-740cc rang depending on waht you want to do i nthe future. and following that you need a FPR. and also a Z32 MAF.

[skaterfromvt]

I do have the walbro along with the z32 fuel filter...when this turbo goes larger injectors will come with the turbo upgrade and the z32 mas since ill have to get it re tuned anyways...i midaswell get it all done at the same time...

any thing else i can do to open up some power maybe put one of those electronic dump valves to open up the exhaust?

[idahotuner]

you dont have turbo back full 3 inch exhuast?

[skaterfromvt]

3 inch elbo 3 inch down pipe then 2 1/2 from test pipe back i was thinking of one of those y pipes after the elbo where i could open it up and dump it there when i wasn't on the street

[idahotuner]

naw that wouldnt do anything at all. full 3 inch back is the best. but yours sounds good.

posta complete mods list for me to see

[BEST1TUNING.COM]

Your welcome Mitch, good to see you are happy and it is holding up well. You CAN however really see the early powerband and efficiency of the turbo at 15 psi with this dyno plot by following the torque curve, falling off more in the higher rpm.

It is a streetable and VERY fun powerband though

[skaterfromvt]

pretty short mod list..but here it is

as you can see not much except a D*mn Good tune from best1tuning.com !!! runs a lil fuel rich but its better then lean

Thanks!

[DrifterProdigy85]

You cant really do anything at this point to get more power other than upgrading the MAF, Injectors, Turbo, Cams, and Tune. Just gonna have to bite the bullet and go bigger.

[idahotuner]

yep pretty much. i am all ready getting use to my gt2871. lol the need for boost will all ways increase. i am only at 14 psi right now though. but once i get use to like 20 it will be time to go bigger again.

[DrifterProdigy85]

Thats why you just gotta go big to supress that urge. Im putting on my T3/T67 DBB setup as we speak.
