How Much Power Is Tooooo Much?

[MBS206]

It's never too much!

Mr331307 had his running at 500RWHP for 8 months, and the only thing that car did was burnouts, drag racing, or dyno runs (Some of the most stressful things you could do)

It was never treated nicely.

Lasted long enough.

Stock injectors too.

[ULOOOK]

My rb25 has 300kw @19 psi for the last 18 months also. No signs of failure. But i do think that she is on borrowed time. 230-240kw should be no worries.

Btw what turbo are you running?

Stock injectors running 500hp?

all depends, you could daily drive a 300rkw standard internal rb25det for 10years...its all about how you drive it. daily drive it conservatively, give it some herbs every now and then should last years...take it to the track and its unpredictable/

[DjeMz]

since when the f**k did u have a RB25 R32?

Hahaha Gold! Must of traded up on the LTD gas V8.

hahahah nah still got the ltd as a daily

20psi to make 230 - 240kw = you chose the wrong turbo or your tuner is shit.

I have heard that anything over 18psi is asking for a shortened lifespan on stock internals

The car came from japan with the rb25 in it (hasnt been tuned at all in aus), hks 2535, with supporting mods.. but the car atm is running VERY rich.. like ill just rev it to about 4 n petty slats out a bit, so until i take it for a decent tune, she will not be hitting boost in an effort to save petty lol

I was thinking of taking it to DR DRIFT Sam C, i know he specializes in ca/sr im sure he can do rbs just fine, but i have heard mixed opinions about his work, can anyone else recommend a good dyno tune place in Melbourne?

Also, to sort of solve the whole running rich thing, if i disconnect the battery to reset the ECU would that get things running better before i take it for a tune?

hahahha

well the 25 is in a s13 silvia... and std computer, std injectors.. standard everything except for GTR pump... lol

i didnt believe it untill i seen the dyno read out...

neways he is building another motor with gtr rods n pistions...

neways he knows what he wants

Is that the 280rwkw car your talking about?

Std injectors & ECU?

Not really, a 2530/2535 is goin to need that much boost.

They are only a tiny turbo, and IMO for a fat mid-range, quite a good turbo choice

the car he is talkin about is mine... it a freak.... i mean i understand that a dyno is only a tuning tool and counts for verry little, but when it backed it up with a 118mph pass at the strip with limited traction til the end of third (i cant drive to save myself on a drag strip) i figured it cant have been far off the money

as below

[R31Nismoid]

Chipped ECU? And no FPR or you did have an FPR?

Sometimes you dont even notice the ECU has been fiddled with.

[drag-on silvia]

well i had a look at the computer and it didnt have any stickers or writing on it to indicate it had been played with, and no, no fuel reg. basicly the only thing the car has got it an rb25, delta fin cooler, full 3" exhaust, gt3037 @ 14psi with 38mm external gate with screamer and an old school sub zero plenum. the injectors are stock as far as im aware, the afm is stock, (series 2 engine if it makes a difference. ) but yeh, it does go well

[DjeMz]

Thanks guys for the info

R31Nismoid, so if i run say under 20psi, turbo and internals should be ok?

btw has any1 got a 32 gtst bonnet?

A high flowed stocker (GCG or Slide) can make 250 on ~18psi, so my "wrong turbo choice" statement stands.

My Slide high flow makes 18psi by 3250rpm, makes for a nice fat mid-range.

[n0nac]

lol as drag-oon-silvia said lol

he would be my mate i was refering to...

krazy car....

but yeah its hard to believe those numbers with std just about everything lol... its just a freak of a car haha

Very true. If you redline it everyday it wont see christmas. If you take it easy and give it a bit now and then it will last a fair while longer.

if i remember correctly there are a few issues with RB25 ecu's, i think i remember sam saying somewhere about it.

[Adriano]

It depends if it is a chipped r32 rb20 or 25 ecu, or a stock or chipped r33 ecu, i cant see it possibly being a stock r33 ecu. In my experience there is no such thing as a freak car, maybe 10 rwkw, but not 50, and ive done 100s of power runs in cars. If it makes that power, it does it for a reason. It appears to have the supporting hardware, now its just the injectors and management, you need to pull the cover off theecu and have a look.

[khunjeng]

I wouldn't run much over 18psi on stock internals. Mine does and has been runing fine.

You totally missed the point of what i said.

The GCG is a larger turbo. It has a larger set of wheels.

This means that it will flow more air at a given psi.

A smaller turbo has smaller wheels in it so flows less air... this is bit generalised point but im sure you see the idea.

Saying its a wrong turbo choice is wrong and very mis-informed.

Its like me saying the GCG turbo is a wrong choice for 250rwkw because a GT35 will make that power on 15psi.

See how dumb that sounds?

The GT35 has LESS response, the GCG a bit more, the HKS 2535/2530 even better again.

You cant come out with "its wrong".

[The Mafia]

oh, and you simply can't make 270rwkw on 10.7:1 afrs...

[DjeMz]

you need to pull the cover off theecu and have a look.

Where abouts is the ecu? Ill take and upload some pics right away..
