411rwhp from stock internals

[MRK25T]

What is the formula to achieve 400rwhp?

My injectors (also stock items) were at 72% duty at 250rwhp on 0.8bar boost. I've been told by my mechanic not to run more that 1.1bar boost through my high flowed turbo (R33) because of my internals. 300rwhp would be nice if I knew how to reach it.

I got to 296.9rwhp on the stock turbo, so all 300 requires is an upgrade turbo.

I'm using a GT30 500hp turbo on mine, Wolf 3D, Greddy plenum, R34 GTR intercooler on mine, but there are plenty of other setups that will give you similar power, a good tuner is a must.

Pauls car was one of many cars being set up for a Dyno comp to run on another Dyno so i would have to be stupid to jack up the power when its about to run in front of hundreds of people on a different Dyno.My Dyno was calibrated less than one month ago.

At our test day ( the day we got 411 out of Pauls car) we also had near standard GTSs making less that 200rwhp.If you use a very good pump and rising rate fuel reg plus a good ecu you can feed the samesort of power on stock injectors but use standard pumps and you will struggle to feed 300.We will get Dyno Dynamics to prove this car and post the results but it is really making 411rwhp, ask any sucker thats been silly enuff to go for a ride.

heh im a sucker thats silly enough, the boost kicks hard

How much boost did you need to achieve that figure?

Must be something wrong with my car

JimX, I wasn't disagrreing with you there, just saying that most of the dyno's we (SAU WA) tend to use in WA are the accurate ones, and we leave the high reading ones to Silvia owners who need all the help they can get:D

i DEMAND you take that back.. :shake: although im in qld.. i dont really care about dyno readings at the moment.. my car is pretty much stock.. 4.3 diff gears and exhaust (std dump) oh and its rb20.. i ran a 14.0 with an apparent 220.5 hp reading (this was with 1.0bar boost) in shootout mode at what i am lead to belive was subzero's dyno.. i know there is a lower time in my car because i used sh*tty tyres, screwed my start up and had axle tramp.. i think the best way is to find your mate with the power on the street and go from there.. but then again its illegal.. so organise something.. meet in the middle of aussie and use rolling starts.. then no one can blame sh*tty starts.. yea well i forget what the whole point of writting something was.. but just because you have all this wonderful power doesnt mean youll run a good time.. maybe a dyno is the only way to tell..

296.6 was@1.1bar and yes the Turbo did die after a few weeks.

rbs13, I was only have a tease of all my mates with Silvia's, it's an on-going rivalry. I think there great cars, and the power to weight is in your advantage. I was beaten on the day I got 411 by a Datsun 1600 with an SR20 pumping out 433rwhp, so I have much respect for the engine:D

MRK25T, I don't recommend pushing the stock turbo as hard as I did to get that sort of power, but I was planning on replacing it anyway, so we upped the boost. With an aftermarket turbo you should be able to make 340rwhp easy on just over 1 bar, if your not then something isn't working right.

[DCIEVE]

damn i really really want a ride in this car....

well done paul & steve

I've got a high flowed standard R33 turbo along with the stuff you have on your car (I have a powerFC though) and tuned at .8bar it only managed 252rwhp. I asked if it could get anywhere near 300 if I increased the boost to 1.1bar and they said youd be lucky to get 280. The car seems to be holding back.

Thats terrible. I'd be taking my car elsewhere, Mrk25t.

Indeed Hicks.

I've got a Z32AFM now (standard was maxing out) and i'm just thinking about getting a HKS2530 turbo to replace my high flowed one. I've never been to unigroup (or whatever the place is called) but from feedback on this forum they seem to be quite good.

Maybe I should get my car checked out by them first with a list of recommendations of what to fix/replace. Getting the car tuned is expensive

[Steve]

Mark, do you have cooler and exhaust? Cos the power you are quoting is below what the stock turbo is capable, so I dont know where whoever sold you the turbo gets off calling it a high flow.

- somethiing is just not right there, sorry to say.

3" HKS catback exhaust + hi flow cat and front/dump pipe (probably no-name brands).

FMIC I think is Micks metalcraft

I also have regulator, pump, profec b, powerfc, clutch, adj cam sprocket (which wasnt touched in the tune), non ball bearing high flow standard R33 turbo, pod filter.

[Steve]

And lets not forget a nice bonnet:D

I think it must be turbo, how can it be a high flow if it flows less than the stocker? You have all the rest of the good gear on there.

[Steve]

Having said that, it could be a really ordinary tune.

[MRK25T]

Do custom manifolds help at all - I just want to complete my car, get it tuned, and then leave it.

[Steve]

A good manifold will help, but I think you need to get the set up you have sorted first (thats what I would be doing) as you 'should' be getting alot more.

To give you an idea, I took my car to morpowa (here in SA) after having a tune and not being 100% happy. He (martin donnon) got me an extra 26rwkw, with no increase in detonation, and better idle and part throttle response.

He asked me what setup I had, told me what sort of power I should be expecting and low and behold, thats what I got.

Having someone who knows what they are doing makes a huge difference - bit like Steve SST and his wolf ecus

[Steve]

And a big congrats to you too, Steve, for the result with Pauls car, ever thought of moving to SA:D

Its a worry but i have seen many so called Hiflows not match the standard one so be carefull. Best thing is to find the extra cash for a proven after market job.
