Rb25 Power Output ... Low Or Avergae?

[cactus]

Hey guys, had my car dyno's was expecting a little more but anywayz, though maybe we could have a discussion on here =D

RB25DET

GReddy Intake

80mm TB

FMIC

3" intake pipe

BOV

Billet fuel rail

550cc Inj

Bosche 910 pump

surge tank

Sard Reg

high flow fttings etc

GT30R .82r

kazama manifold

44mm Gate

3" system

splitfire coils

EMS 4424 stinger

Auto box, had a manual valve body but box i believe was slipping at time of tune

330rwhp @ 16.5psi

think something is wrong? or do i need to retune once i get my properly built box back from top quality transmissions?

I wouldn't be trying for too much more than that out of a standard? 25. There are some that can reach the high 300's & maybe a bit over, but it is risky & it depends how it's driven.

[showbizz]

330rwhp of stock internals is pretty good dude id be happy with that...

[bubba]

245rwkw.. I think Cubes is only making ~280rwkw with the same turbo on an RB30..

You're probably lacking 30rwhp or so due to the auto, shrug.. got a dyno sheet with afr's?

[cactus]

yeah will post for yas tomorrow

[sidewayssam]

you have that hq and was there as i got mine dynoed right? i wouldnt be trying to get more than 330hp on stock internals

[Chi100188]

hmmmm i think SKY34 has stock internals and has 400+ hp? and is still going pretty strong? i think hahah but yeah i guess depends on the condition of engine and tuen

[RRob]

Bunch of fairies.

400 minimum is the new standard for 25's

[GTS-t VSPEC]

It does seem a little on the low side, but as mentioned, without risking engine damage low 300's is at least safe. Post the dyno graph and we may be able to give more insight.

+1

Isn't that PANIK drift car making 410rwhp on a stock internalled 25? and that thing cops a hiding!

[RRob]

462hp and done a season of DA and local events.

Jack from xspeed 480???

Scradly's 34 did 410

Kizza's 32 drift car 416.

Just some examples:)

[bubba]

There ya go! Someone needs a glass and a half of full cream concrete

[Marco-R34GTT]

With what? Stock internals??

WTF!!?!?!?

[Kaido_RR]

With what? Stock internals??

WTF!!?!?!?

yes, it can be done

[RRob]

Yes stock bottom ends.

I think most people opt for drop in cams though.

[ix9]

350-360rwhp is the norm these days anyway

[Marco-R34GTT]

From what I read, I was under the impression that by 300rwhp the RB25 would be on a knife's edge for reliability....

Hmmm....

i have been running 335rwhp now for over 6months without a problem, (most likely longer just cant remember), also ive taken it to the track more than once and had a full drift pract day at the track without a problem

[SKYRYAN]

300rwkw maybe..
