HKS GT-RS turbos...anyone have this setup?

[Marko R1]

Hi guys,

I've got an r32 gtr with the above turbo setup, i've searched the forum for other peoples experience & cannot find the answer i am looking for...

Are there any 'other' gtr owners out there with this setup? I am after an approx. awkw rating.

I have read 3 other posts specific to this turbo but it seems that nobody has really given these turbines a genuine run due to their lack in bottom end boost.

Im sure the top end delivery would most definitely suffice

Thanks,

Marko.

p.s. where did my post disappear to???

"Bel Performance v's Croydon Racing Development - which 1?"

it was so informative everyone had something to say.

message Mik He's got the same setup as you but in a 33 . I thaught your car had already been tuned by CRD as you said in one of your posts that you were going with them?. My guess with your setup would have to be something close to 400awkw on CRD's dyno but I wouldn't get to involved in dyno numbers get it out to wsid and test it on a real dyno .

My car was scheduled for a tune last week but im sure you all know how these modifications pan out - odd hurdle, hick up here & there.

It will be dyno tuned later this week, just awaiting the arrival of my 3.5 inch exhaust which is due tomorrow.

Brett - I have spoken to 'Mik' before about this but I know that he has undergone a road tune, I'm very interested to see what they will produce on a dyno.

Is there anyone that has hands on experience with power delivery?

Regards,

Marko.

Miks car has been on dyno log dyno which is very very low reading compared to something like a dyno dynamics .From memory I think at the end it was something around the 280awkw mark but I believe they later learned after puting another car on that dyno on the same day it was actually reading lower then usual the result should have been something along the lines of the 310-320awkw mark but I'll the man himself step in and correct me .

After seeing the peak power dyno results from a couple of CRD GTR's and there times out at wsid I'd say his car would be pretty damn close to 400awkw on a dyno dynamics.

I have them on my R32.

Engine is being rebuilt at present, but the following dyno graph was at 18 psi and a fairly conservative timing map.

I expect much bigger and better things to come :uh-huh:

[Marko R1]

this dyno sheet you have, is this rwhp or awhp?

rwhp

note also the terb shuffle during boost build-up. I have since gone to a bridged HKS manifold that should reduce this effect markedly. I will also be expecting 550 or better rwhp with more boost and timing.

My car was road tuned and had the tope end "touched up" on a dyno log as Brett pointed out.

The max power we saw was 292 awkw. This was at a fairly rich 11.6:1 AFR and pretty sane boost.

Two weeks later, a certain WRX made 230kw on this dyno and then made 290kw on a dyno dynamics the next day.

I guess that gives me about 360awkw on a dyno dynamics which alogns well with my 124-125mph trap speed in a heavy BCNR33 Series 3.

mark34gtr was using these i belive he ran 10s with them

Gav, mine makes about the same power as yours.

i have twin hks 2835's 52t

on the dyno we ran 1.3bar but took it back to 1.2bar because im still running cast pistons and the injectors are maxing out. the next step is going to cost a fair wack unless someone is selling a rb26 with fogies etc

[williamsf1]

so whats max boost for stock pistons with these then?

[MELV]

would like to know the answer to this also..... ?

i would say, it depends on how long u want the motor to last.

[Marko R1]

it would also depend on how heavy your right foot is...anything will blow in the wrong hands, in the right hands it will last.

jim @ crd mentioned that up to 22psi is safe & that quite a few guys also run 25psi, usually if they want to run a 1/4 mile.

anymore than 25psi would be really pushing it i think
