Decent Power Figure For Gtt?

[yld34t]

Regarding the following mods to my R34 GTT, is my power figure in the ball park?

PFC

GCG standard turbo highflowed

Turbo back exhaust

Ebay front mount(!!!)

Splitifires

Greedy boost controller

Inclosed pod filter with cold air pipe

480cc Nismo injectors

Sard reg

Walbro pump

Tuned at 16psi, bleeding down to 14-15psi at 7000rpm

230kw at the wheels

[R31Nismoid]

Sounds normal

If you have a read of the RB25 Dyno upgrade (its a sticky)

It would also confirm this

[joeyjoejoejuniorshabadoo]

thats on the money

[PM-R33]

Yep sounds right, maybe invest in a better boost controller so it holds the 16psi to redline instead of dropping off if you want those extra few kw's.

[Housie]

have u checked the boost the turbo is generating; rather than the pressure at the manifold/boost guage?

Just curious to see what the compartive figures would be with the ebay intercooler. Dont want to go cooking the hiflowed stocka!

...but yes results show nothing odd!

[yld34t]

Thanks guys, I appreciate it.

I might look into the pressure drop over the Ebay special cooler. I have had lots of people comment on how good the core looks, but they are just that - comments.

Might be worth checking the temperature drop too??? Especially at Supersprints.....

Yeah its ok .. can pull more out no worries.. I run 260 easily can take it to 280 if need be. Highflow too .. but use cams.

In all honestly I was running that power with a SAFC, Stock turbo, Stock fuel pump (was fine not leaning), Stock injectors, Stock ECU, CAI and thats about it..215 minimum

So honestly 15more rwkw with a highflow and etc you should have more .. Get a new Actuator and hole to gate closed for quicker boost build and holding boost.. GCG sell them HKS do so also (one on ebay now)

215rwkw minimum from a stock turbo? Thats called a happy dyno

[DECIM8]

Are you for real? A auto pulls 200rwkw Easily on the stock turbo.. I just watched a auto pull 201.5rwkw

Its an R34 GTT remember not a GTST.

I have been at the strip and easily beat my friend in a GTST with 221rwkw so you take what you will but you must be dreaming if you think that 220 is not achivable in a manual R34 with flow mods..

At the same time I did run a R34 with similar mods, Intake (cheapo like yours) and exhaust (cat back) with stock ECU and it was very held back.. I beat it by about 1.5 cars

Forgot to mention full exhaust.

[R31Nismoid]

Yes i am for real. 215rwkw, i bet you wouldn't even come close to running 111mph @ the strip, because with 215rwkw, thats right where you would be but id expect more around the 105mph just like everyone else.

You beat a car with more power by 1.5 cars? Doesnt that ring a bell right away to you?

Because it sounds like someone doesn't know how to drive if the cars had the same power, so again, it has nothing to do with power at all that example

next?

[Wacky Dee]

I have a GTT with a stock (but remapped, not too lean 11.5 I think for AFRs) ecu, stock turbo at 11psi (greedy profecb) and turbo back exhaust and the car makes about 190rwkw at unigroup.

[DECIM8]

Look put it this way .. That car was also running a stock turbo with injectors and putting out 215rwkw with PFC, Injectors, PUMP, fuel reg etc

A GTST.. R33 .. On a dyno day at UAS I think (the last NSW dyno day?)

My car is faster than that.. or im a better driver .. either one your choice..

Point is 215rwkw out of a stock turbo on a gtst is that easy why cant I do it on my R34.. I think you need to see it real life.. If only I had a print out..

Surely someone has something to post up for him..

R34 GT-T

Stock turbo

Full exhaust 3"

Pod Filter

FMIC

SAFC

EBC

BOV

205.7 KW @ 12psi

Is the best ive found in the search in dyno results thread.

I must add I was running a Blitz SBC which gives better boost/power through the entire rev range supposedly.. May be this.

Oh even better

I agree with Ash, the most I could get out of my NEO is just under 200rwkw.. and that is with all the supporting mods required.

The stock turbos just dont have enough flow and 218rwkw at 12psi is a fair way out in my opinion. Even with HKS GTRS and 15psi I was only getting 236rwkw.. So are you telling me that a bigger turbo with more boost is only going to give me less than a 20rwkw gain?

Any Drag MPH's to back that power figure up?

[nitestalkr]

Mine:

R34 GTT

3" exhaust

pod

splitfires

manual boost controller (turbotech)

pfc

hybrid fmic

202.9kw @ 9psi (peaks at 12psi), just under 7000 rpm

I also have fueling issues and can say from my exp that stock injectors wont run far over 200kw.. generally 100% duty cycle at 7000rpm

tuned at RE

Exactly.. mine at a little less power and running healthy AFR was nearly maxing out the injectors as well. I dont believe the stock NEO injectors will provide much over 200rwkw.

[DECIM8]

well I run 260rwkw with more to pull on a Rb25 neo engine why cant you guys do it? This was with highflow

I dont even have a FPR..

This is quite interesting now.

Here is my graph to back up what i said above..

Although, to add to the current discussion a bit more... i would hope once i have injectors, fuel pump and highflow/brand name turbo that i would be around 250rwkw at maybe ~16-18psi

What other mods do you have?

I also have quite easily pulled out 265rwkw with the GTRS on a neo

[Strik3r]

dyno figures are meaningless unless you back them up with real world figures (like trap speed).

If you want to delude yourself into thinking you have 215rwkw on a basically stock motor with an exhaust and some boost, then go ahead. The 2 dyno graphs pasted so far both have been @ RE.. so im suspecting a happy dyno like ash said.

run a high 12 @ 112mph and we'll believe you.

[colossus]

I pulled 200rwkw on an R34 auto with stock turbo and SAFC at 11psi. With a manual, a highflow, PFC and 16psi you'd think you'd get more than an extra 30rwkw. Then again dyno's are just tuning tools and not really comparable.
