got my car tuned today...should of made more power what do you guys think??

[ka-t_180sx]

i made 285whp at 16psi @ 91octane....

my setup---------
.apexi power fc
.550 nismo injectors
.s15 bb turbo
.walbro fuel pump
.brian crower 264 cams
.megan manifold
.3in turbo back
.hks intake
.greddy FMIC
.greddy Iridiums 8 range
.greddy RAS

[Monooxide]

I agree.

Should be over 300 WHP if it is a S15 Turbo and not an S14 one.

[weissguy]

post dyno sheet and type of engine

[Flicktitty]

seems average.... but i agree should have been over 300whp.

[vespaman]

about the average. it could reach to 300 or a little over if you raise the boost to 18psi and run test pipe i guess.

what type of dyno?

who tuned your car?

[norcal_black240]

Numbers seem average to me if this was on a mustang dyno

[ka-t_180sx]

driftspeed.com
Dynapack dyno

[Monooxide]

3000 or 4000 series?

[ka-t_180sx]

i dont know

[1989rps13]

average id sayy

[design240sx]

should of made over 300+ though.

[ka-t_180sx]

285whp feels good...but i need more power 300whp....lol

[lflkajfj12123]

285 doesn't get your e-boner up when u see those numbers

300 or bust amirite

[JeremyR]

somethings wrong with your setup...either bad motor or bad tune... should of made more power at that level of boost...

[EDacIouSX]

you should ask driftspeed about those numbers and if they noticed anything wrong. they do pretty good work.

[Sileighty_85]

does seem a little low

My red top on stock Cams,370cc Stock ECU, MAF,T28, @ 10psi made 254whp

[GSXRJJordan]

Seems totally normal. Post the graph, that'll tell the story.

[Psycho 240 Freak]

Mine with the HKS GT2530 only made 270 whp at 17 psi, but this was without cams and on a Mustang dyno. It's not the tuning either because the motor was tuned by U.P. Garage close by Seattle. Everyone in the area knows that's the place to go for Nissans.

It's probalby not hurting your peak hp output, but isn't the 264 cams not a good match for the S15 turbo? Wouldn't it not benefit the the quick spooling of the S15 turbo?

264's are a great match for the S15 turbo... it's been said by a couple people that 272's would actually make for an even more linear powerband for those wanting to really rev out high.

Post the dyno sheet, stop comparing numbers when we have no idea what correction he's at/how the torque curve looks/etc.

[Zeller]

Don't you think the 91 pisstane had anything to do with it? 93 octane would have definately been over 300whp.

[bkfill]

what weather?, whats the storey behind your tuner?

seems low im sure you would of made it over 300+ with cams

do you have a fuel pressure gauge?

[aNskY]

what weather?, whats the storey behind your tuner?

seems low im sure you would of made it over 300+ with cams

you should get a inline fuel pressure gauge just incase

crower 264's aren't cams?


:keke:



did you degree the 264's or throw 'em in straight up?

[Om1kron]

Don't you think the 91 pisstane had anything to do with it? 93 octane would have definately been over 300whp.

silly us. .2 octane would've definitely upped the cars power 25hp... I'll remember that next time I need 25+ more horsepower. :keke::keke::keke:

[ryangreg]

16 psi is why it only made 285, turn the boost up to 21 psi and see what comes of it.

[Zeller]

Since 285 to 300 is only 15hp I will remember who "not" to ask for simple math problems!! :smash: And why don't you call a tuner up and ask him on a tuned car how much difference there is between 91-93 octane. I garentee there is more than you think (I know from experience), but since you obviously have tuned with both 91 and 93 octane I am sorry that I didn't ask you first!!

[GSXRJJordan]

Haha, yes 93 octane would be nice. Not to mention CA gas has all sorts of other crap in it that makes it perform worse. Annnnnyyyywayyyyy...

Like I said, weather and correction can make all the difference to "bench racers". And Ansky - I always ask why no one runs adj cam gears to degree them in, and the unanimous response is that with SR's there's really no benefit. I don't know anyone that runs them, whereas with most other motors they're a must when you buy cams.

[ka-t_180sx]

found out why im making 285whp....compression tested 110-140-110-130....got a new tune 260whp @ 15psi.........

[Monooxide]

That sucks dude...I knew something was awry.

[Om1kron]

it's a KA man, keep on trucking until it shoots a rod lol. j/k

[DrIvEsldEwAyS]

i was making 277 with stock cams, dynapacks read low, those numbers sound right. i miss that turbo, i went from that to the 2871r and hated it, now im 35r and hate the response but love the power. +1 for s15 turbo

[Om1kron]

I'll make sure to keep the same thing in mind when not needing someone to provide spell check advice.

[DrIvEsldEwAyS]

i didnt see that it was a KA. my numbers were on a sr of course

[GSXRJJordan]

It's an SR20, hence the "140" compression numbers on stock internals, PowerFC, and red "SR" logo next to the post title.

Wayne, you're zero for two on this thread lol.

[Sileighty_85]

^^^Damn beat me to it haha

Its not a KA its an SR

Notice it say "SR" in the thread title and also he is running a PFC
Apexi never made a PFC for the KA

[Om1kron]

Man let me tell you guys, they put some bomb ass shit in nyquil... Maybe I shouldn't work on my wiring harness tonight LOL! :cops::cops::cops:

[ka-t_180sx]

anybody got a spare block for sale???? wheres steve shadow???

[Om1kron]

ah... now I see. LOL user name is ka-t... I thought something looked weird when I saw power fc... anyway. `

[ka-t_180sx]

why does my car have low compression???its not the piston rings cause theres no smoke coming out the exhaust....please help me...yu guys have been really helpfulll i really appreciate it....thnks

[kingkilburn]

It could need new rings, valves or valve job, bad gasket some where. . .

Did you have the head checked out before you assembled the engine?

[GSXRJJordan]

HEAD GASKET.

Power Enterprise/Apexi/HKS/Tomei.

[JeremyR]

apexi headgasket.

thats all you need to know.

then hit up steve shadows. i think he is in the aliso viejo area???

[bardabe]

yeah definetly get a head gasket and hit up steve.

[TheRealNighthog]

A problem that I have noticed with BC cams is that they were not designed on the proper centerlines for just a drop in situation. You need to cam gears to play with them. My favorite cam for "just drop straight in and make great power" is by far the Jim Wolf S4's

[ka-t_180sx]

anyone got a headgasket for sale????

[Om1kron]

best bet is to buy new man, I would never put a used head gasket on my car... hey man at least it's running right now. whens the last time you checked the coolant and everything?

[Def]

You have to run right on the ragged edge of timing (on 93) to hit 300 rwhp with only ~16 psi up top on a T28 and no cams. If you can hold 18 psi up top then 300 or more is pretty easy.

I'm thinking they left a little bit on the table, but this is a good thing. "Really high" numbers for a given boost and a jagged power delivery line mean you're getting phantom knock. Engine might last like that, or it might knock a little bit more on a hot day and smoke a ring, it's a gamble.

I've seen a few dynos on here that look like they kept adding timing in until the motor stopped making more power, which is not the safest thing to do on pump gas without carefully monitoring the knock sensor, and most shops don't do that.

FWIW, I made 300rwhp/275-280rwtq at 16 psi on my GT2560R(T28) with stock cams and a FReddy intake mani. I normally took a degree of timing off in boost for street driving, and another degree off at the track and lower boost for safety.

thats true at least its driving now...the tuner saids its reliable...he couldve made more power but it wouldnt be reliable AFR is 11...i havent checked coolant...

[lflkajfj12123]

jwt cams

headgasket

retune

[Om1kron]

thats true at least its driving now...the tuner saids its reliable...he couldve made more power but it wouldnt be reliable AFR is 11...i havent checked coolant...

I would drain and refil with new coolant just to make sure that it's still semi sealing correctly and it's not mixing water with your oil.

Before you go throwing good money after bad and spending time on a Head Gasket, you should have your shop do a LEAK DOWN Test and see if you are losing from the head/intake side or the block/exhaust side. this will give you a better idea of what you need to do instead of basing your repairs on desktop/keyboard diags.

Just my two yen.

[ryangreg]

^^^seriously....

what are all you retards shouting "headgasket" at this guy for when you have no fucking Idea.

more than likely it needs a valve job, but needs a leakdown test done to verify.

[kingkilburn]

I would be thinking valves as well.

[ka-t_180sx]

thanks guys...im a get a leakdown test...

[ryangreg]

as for everybody who shouted headgasket, suck a fat dick seriously :fawkd: where is the angry face flicking you off icon??
