i thought it wud at least be at least 240whp

What do you guys think?

[slider2828]

Depends what type of dyno... What boost level....

[silvia13t14]

Depends what type of dyno... What boost level....it was a dyno dynamic it was at 10psi

[ManoNegra]

sounds like a perfectly healthy stock S14 SR

[nate_drake]

honestly, you dont have many power adders i wouldnt expect too much from it...

[bl3ujay07]

well, how about the butt dyno? Seems good or bad?

[burnsauto]

you have an exhaust and a front mount, you're right where you should be at.

[jr_ss]

There's nothing done to the car, so don't expect much. 240hp at the crank is what you do have. Get injectors, up the boost and get a tune and you'll see more power.

[drftmark]

dbl post ftl zilvia servers slow as fuck

[drftmark]

Dyno Dynamics reads pretty freaking low. I was pretty disappointed in my results as well, but after doing research on the dyno, it makes sense.

I had 268whp or 286whp (can't remember which) with a gt2871r .86 at 17psi with HKS 256/256 cams and other things. So I would say you are about right.

you should be very happy your not getting 180ish HP like most guys that go SR lol.
thats the HP that engine should be.
why did you expect more?

[MADE]

I wouldnt say the DD reads low, it reads what your putting down.

My first tune by Steve Shadows netted me 201Whp. Pretty much the same setup minus 740cc injectors, PFC and 12-14psi. My stock SII RB25 netted me 212.Point is don't expect much from a stock JDM engine out the box, least you have a baseline to see your progression.

[Norty]

I can't agree more. Seems to be just where it should be to be a stock s14 sr. Nothin irritates me more than a few guys i have seen saying that their stock s14 sr with 18 lbs made like 280 or 300 to the wheels. I just laugh because i'm like the damn turbo doesn't even support that much, much less making that at the wheels. So i'm with these guys that I would rather have a dyno that would give me real-world numbers.

[Flicktitty]

My stock SII RB25 netted me 212.
:hahano: :duh: :hahano:

[s14_sr20_silvia]

I have basically the same mods + maybe a couple extra things..
I have a tubular manifold and 3" turbo back exhaust... 10psi on stock S14 and I made 215 whp 217wtq, so with a couple less mods I'd say you're right on point.

[Chernobyl]

Sounds about right for the engine and mods.

People hype the shit out of SRs, RBs, etc on forums. It's easy to believe that they all make 300hp with bolt-ons, but it's not the case in reality.

oh its east to get 300 hp out of an sr with bolt ons, bolt on some pistons and rods, bolt in some valves springs and cams, bolt in some injectors, bolt on a larger prefferably top mount turbo, (dont take the bolting on of pistons and whatnot literally)

and then get it tuned

easy 300whp all day lol


but to the OP you are right where you should be, now you have a great base to be able to see what kind of gains you are actually getting when you do some more intense mods down the road.

[silvia13t14]

:D:Dsounds like a perfectly healthy stock S14 SRThanks :D:)

[smelly240]

bolting on all that stuff should give u 400 easy - lol

[silvia13t14]

Thanks for all the feedback.. I guess i was getting lil in over my head lol But to bump up the power a lil I think im going to raise the boost (14psi), get 600cc injectors, fuel rail, and a exhaust manifold

[silvia13t14]

:fawk:bolting on all that stuff should give u 400 easy - lol:fawkd::madfawk:

[kouki fanatic]

dyno dynamics read 205 on my cousins e36 m3. it had a fan delete, exhaust, and CAI. not much but it shouldve atleast been at 225. they read about 20 less

[s13Eper]

Don't worry about it as long as the car runs good. It seems dyno's and dyno opperators vary quite a bit. Just had my bone stock redtop (even oem air box and smic) dyno'd on a Mustang dyno a few weeks ago. Made 228whp/207wtq... obviously high and inaccurate for a stock sr... especially on a Mustang dyno.

[Jacob'S13]

Did you forget to put your stickers on the car?

j/k.

Well is this dynoed on 91 octane or what? Im guessing it is but correct me if im wrong.

But 205 rwhp isnt bad, atleast your gonna be able to pick on honda's lol.

or just get more HP adders. manifold, bigger injectors etc.

[PANGES]

Your power on a dyno dynamics isn't bad at all actually. For what it's worth, my Evo was tuned on a Dyno Dynamics. A stock Evo is rated at 286hp and on the DD it makes around 230whp-ish. What you made is pretty good considering you have very basic mods.

Side questions: Aren't the SR's normally supposed to run on 98 octane or whatever? I recall when I had my R34 RB25, it said hte minmum was 98 or something like that... if you're running a motor that's rated at 240hp on 98 octane with just 91 octane and still making that much power, I'd be quite happy.

[silviaguy240]

98 octane in japan is equivalent to like 91-93 here.

[boostdd]

What are s14 Sr's rated at 225 crank ? ,205 whp seems good to me considering ur mods

[PANGES]

98 octane in japan is equivalent to like 91-93 here.

Really? lol. Pwned me. Good to know.

[silviaguy240]

yea the formula is a bit different since they have an extra or are missing an adative we put in our gas.

It was on 93 octane and a lil bit of 108 octane booster:hsdance:

i'm guessing you'll get 230-235hp next time...

[Jadeskyline]

Seems about right. UP the bosst a little and then have another go at it. A T25 wont net you any spectacular #'s

What do you guys think?

I think those are good numbers?

[spooled240]

shoulda went ka-t haha..

but those are decent numbers IMO, a stock s14 sr is what, 220 at the crank? and about 180 to the wheels? 205 whp on a dyno that usually reads low seems to be pretty good.

But as long as it runs good, you should be happy. I'm only running 8psi on my ka probably making about 230ish whp and I get the urge to turn the boost up but it's fast enough for daily driven street car IMHO. I would rather be able to beat on a low 200ish whp car than baby a 350 whp car and pray that things didn't go wrong O_o

[MandTPhotography]

I know the S13SR and S14SR aren't the same, but they are similiar.

SAE corrected on 14lbs I made 241hp/248tq on a T25.

Exhaust, FMIC, Koyo Rad, MAF, stock fuel (It's at 12lbs now.), and a Apexi Neo.

dyno your Ka-t and see the surprise on your face when you see your not making 230whp on 8psi with your Ka-t. I daily drove my 430+Whp Evo8 with Zero problems. drove that thing everywhere.

[DreEzed]

Seems about right. UP the bosst a little and then have another go at it. A T25 wont net you any spectacular #'s
FYI its a T28.He's running a s14 sr20
