Devostating Dyno Results For R34

[scottmiller]

hey i recently brought a skyline r34 gtt everything is stock, so i decided to put it on the dyno to see what is puts out in only managed to do 184bhp (i think that it feels faster than that), i was told that they came stock with 280hp is that right, anyway i was devo when i saw the results so i booked it in to get a after market ecu and an electronic boost controller (getting done on 17th). i was wondering what the next upgrade would be best to make more power out of my car.

stock r34 gtt (neo) is 145kw at the wheels, which is 194bhp so your result is right on the money.

280bhp is the GTR

I wouldn't trust that site if my life depended on it.

1. The information was all ripped from these forums about 4 years ago.

2. Its out of date, never updated

The best info is always found by searching these forums, rather than some muppet who claimed limited info from these forums as his own.

IMO that site should be shut down as there is so much wrong with it that it gives me a headache to read

ANYWAY - 206kw = 280hp

184bhp is about 134rwkw... so that sounds exactly right give or take a 10kw difference for dyno's etc

So realistically there is nothing devastating about it at all, its a factory car making pretty much exactly the factory HP/KW.

To be honest you need a full exhaust etc before a ECU/Tune... You wont get anywhere near the gains with JUST a ECU/Tune as you would if you put a decent flowing exhaust on there

[trel]

don't be upset dude, as others have said. if the car is stock (completely) then thats RIGHT on the money on what your car should be making. Look at getting an exhaust and an EBC running around 10psi and you'll be making about 160rwkw maybe less depending on the dyno.

First question, no, that's wrong.

Second question, there are threads on this, what exhaust system are your running? And are you running a decent cat converter?

Yes, people often go the ECU + more boost + exhaust system and either a pod filter or airbox panel filter upgrade + good tune and get a nice gain

nevertheless what I posted was correct. his dyno result is right on the money.

you just reposted it in about 1000 more words.

Hey, maybe im a bit confused, i thougth that the GT-T's came out with 206kw(flywheel) as well as the GTR? Ok maybe not 206 but it should still have considerably more then the R33 (187).

So on paper given a high 20% D/T loss, a healthy GTT should see around 160-170rwkw stock form am I not correct in thinking that? 184hp is a mere 137rwkw.

When was it serviced last?

Could you post up your dyno sheet by any chance?

yeah i thought it would put out more than what it did, last service was about a month ago

yeah here is dyno sheet

[eeiko321]

yeah apparently in general alot of cars lose around 30% of power through the drivetrain

If a mechanic advised you to spend money on an ecu and boost controller, before exhaust and even a better quality air filter (in the airbox), you should go else where; It seems he is just interested in making the most money from you and doesn't care about your interests.

Fair enough he may have gotten confused about the power figures etc, but any good mechanic would recommend upgrading the factory exhaust system first.

[bnr#@]

Is the car manual or auto?

[trel]

guys, seriously now, a "non-happy dyno" on a stock car will go anywhere from 120-140rwkw depending on the health of the car and other factors. as al said too, you're mechanic is probably saying that to you to squeeze $$ out of you. oh dude your car is really low on power you need this this and this now to make it go hard.

first things first. get an exhaust, a cai, and maybe a hi-flow cat. you will notice a very nice gain alone just with those mods.

[joeyjoejoejuniorshabadoo]

that result is on the money....

its not really a FAST car until you make it into one

[sneakey pete]

280HP is what's listed on Wikipedia.

Wikipedia is not to be trusted for things like that.

[Kujotk]

if your going to be boosting it id be putting a larger intercooler at the same time.....

also the r34 gtt is alittle heavier than the r33 gtst so the extra engine power is almost cancled out so not much differnece in actual real life power between stock r33 and stock r34...

[wolverine]

they drop about 60kw thru the drivetrain in manual form.

[scottmiller]

the car is tiptronic, yeah i going to get intercooler put in this week, and the rest is getting done next week
