278 kw @ wheels standard turbos and internals R34 GTR

[jezzrrr]

I a very happy father of a R34 GTR that pulled out 278 RWKW on a conservative dyno (SST's) with:

* standard turbos

* standard ECU

* standard fuel system

* standard internals

+ full Blitz exhaust

+ HKS dumps

+ HKS pod filters

+ Trust intercooler

+ 1.2 bar Boost (Norgren boost set up)

article from SPEED magazine has a quote:

"leaving the GTR unmodified is as cruel as teaching bears how to dance"

I couldnt agree more. More mods on the way.

John Munro's old bayside R34 did a 272kW at the wheels but there was a PowerFC involved IIRC. Seems about right and quite a huge amount of horsepower for what is a reasonably stock motor.

Hi Jeremy, Steve told me about your car, I was blown away by the figure, even though you pushed the boost quite high for the stock turbos. Bummer I wasn't there, as I'm there almost every other day. Hope you have lots of mods planned:D

Don't forget that SST's is a Shootout Accredited Dyno, so the power readings should be able to be compared across all of Oz, without people thinking the figures are bullshit:D It goes to show that the R34 GTR was much more than the gentlemans agreement 206kW would suggest. The most we've had out of a stock turbo'd R32 GTR is 344rwhp on the SST dyno.

Hope to see you car at the next SAUWA dyno comp:D

Cheers

[ed]

so did you get 278rwkw or 278awkw on the 34GTR?

sorry to nit pick, just seeing if you converted it to rwd for the dyno.

[jezzrrr]

Paul,

Yeah I was pretty happy and that figure is with the standard ECU although I think it must have been chipped.

Alot of high hp cars seem to come out of perth but without the 1/4 times to match them!!

Do u have a printout of your dyno sheet to post?

[meshmesh]

Wow!! That's alot of kw @the rears. What boost were you running? I'm really suprised & no offence a little sceptical at your figures. I hit 270kw at the rears on ben @ racepace's dyno in shootout with the following:

Stock Turbos - ~15psi

Apexi Power FC

Cam Gears

Full Exhaust (stock cat & dumps)

HKS Pods

I doubt the ecu is stock, have you checked it?

[Snowman]

I had a 100% stock R34 GT-R V Spec put on a dyno at AVO in chelt and it produced 221rwkw.

Mine is being dyno'd this week at racepace and I'll post the results here. My mods will be basically the same as jezzrrr plus I'll have a power fc + cam gears. (I even have a Blitz exhaust and a Trust FMIC!)

I'd also like to know what boost you were running on the stock turbos.

[Guest INASNT]

dont trust avo readings. My mate a few years ago got him wolf tuned there and got something like 190rwkw with stock turbo and fmic. Then he went to race pace and got 165rwkw

The stock ECU is definately able to handle this kind of power figure.

I had an R32 GTR than ran a stock ECU, Stock Turbo's, Stock Injectors, Stock Fuel Pump, Stock Cooler etc etc.

In the mods department it had very little...Trust Front Pipes, HKS Hyper Cat Back Exhaust, Straight Through Cat, HKS Cam Gears, Trust Pod Filters and a home made Bleed Valve set to 1.1 bar.

This set up, on the Racepace dyno, made 260rwkw. I guess you have to remember that mine was a much older 94 32 GTR, so the engine and all it's parts would be a lot more tired than a fresh 34 GTR.

In saying all this though, I must admit that this really is taking things to the limit and really would be better if some other items such as fuel pump, injectors and ECU were changed. My 32 GTR was maxing out the injectors and the pump was only just keeping the pressure stable.

Meshmesh, I noticed you list above that you have a stock cat and dumps, if you change these I think you will see a great increase in power and torque.

Cheers,

Shaun.

Funny you say that! Spoken to varous people with varying opinions :confused: I'm

About to go the next stage....

Just picked up my turbos today HKS GT2530's, Waiting for my SARD 700cc injectors, 044 fuel pump, HKS EVC 4 & Z32 AFM's. Asked my mechanics about the dumps & they reckon stick with the stock as they saw no real gain on the dyno..still confused. As far as the cat, I've been told the gtr cat are pretty good flowing, & mines probably half blow out . So dunno? thought about those ces dumps, but dunno if its worth it. Also will dumps for the 33 fit on the 34 later down the track?

[Guest INASNT]

U wont get more power with new split hks dumps but u will get better response and less turbulance in your exhaust system

Great, sounds like you are about to put together a beuatiful package!! I like the sound of all the things you have listed above, they will make very strong and reliable power that can be used every day!!

Sorry, I was being a bit confusing about the exhaust....to clarify.....DUMP PIPES are the small items that bolt directly to the rear of the turbos and FRONT PIPES are the long headers running from the DUMPS to the cat.

I was running standard GTR Dump Pipes followed by the Trust Front Pipes. You are right in saying they may not really be necessary for your power level, the stock Dumps will do fine.

As for the cat, well normally when the R's get complied they remove the stock Jap cat and put a more compliant one on and they are crap!! You are best to get a custom one made. I had a larger Cat from a Commodore or something cut in half and had a 3" straight through pipe placed inside it, they then welded the Cat back together and it was mad!! Looked so neat, you could not tell it had been messed with....which is good for when the EPA or Cops stick there head under your car.

Definately look into your cat and doing something with it.

You must be hanging to get it on the road, will be a weapon!! I ran an 11.57@118mph in mine, so with the right driver, your car could do some fast times.

Oooh and I though I was being harsh.

Will do. Yes I'm hangin, cant wait! I'll be rapt if i could run a flat 13 After that I think my next option is FMIC & Water Injection. A mate who has a street 10sec falcon 250 Xflow, on straight gas swears by water injection, so we'll see for $400~ he reckons it's the best "unknown to many" insurance policy you'll spend.

PS: Sorry jezzzr to hijack your thread. Suppose this could also help you, with your little boy "now that you're a dad"

My Dyno is a full Shootout accredited Dyno that can have its figures backed up by Dyno Dynanics and we usually get higher readings when on other Dynos at Dyno comps etc.

Not every one wants to race their cars but i have a good history spanning more that 20 years so i'm not a key board warrior like others here, I do have Drag-Rally and Black track history with my own and customer cars with lap records and championships etc so i'm sick of insecure people needing to knock our exellent results with no claim to fame themselves so grow up.

[HIRISK]

Track times are the best way to show the potential of your car, wether it be circuit or drag. I ran an 11.57 in my 32 GTR and this in it self is enough for me. Dyno's are used for tuning and not as an advertising tool for power outputs, people seem to forget this.

[jezzrrr]

Yeah I have the dyno graph Im just trying to figure out how to attach it.

Also - while I'm the proud father of my 34 Steve is the proud father os his Dyno Dynamics Dynamometer (and his kids too)- which is about as accurate as I have seen. So dont knock it.

A couple of Adelaide R33's recently ran in the mid 12's they made around 250-270rwkw from memory.
