280rwkw on stock turbos?

i dont think so tim :blink:

The car was dynoed at willall racing by Martin Donnan and Peter Hall reasonably respected tuner and engine

builder respectively. I will post the graph tommorow. The turbos are stock, please feel free to check with Steve Cramp, Manta Racing, also a respected racing driver, engine and gearbox mechanic of some repute and dabbles in a spot of suspension work. In fact after checking it was 283 rwkw on standard boost.

P.S

I bet you know more huh?

All i was saying is 280rwkw from a STOCK turbo'd GTR on STOCK boost is nothing but totally unreasonable

Please tell the crowd how that is wrong, and where your knowledge says thats possible

cheers

This was achived with stock turbs, 3in straightthru exhaust, Pods. PowerFC + boost controller set on stock boost. Thats it.

Anyway, back on topic. To the OP, you should be fine without one untill you do other mods.

What is the difference between the blue line and the green line? What does the blue line represent? Is that your car 100% stock or something?

I have posted up a 4wd drive comparison, this was prior to the PFC, boost controller, front pipes and exhaust. I agree with dyno results being all over the place but what can u do about it you have to trust someone or something, I am at the point where as long as it keeps going up who cares. I might add I change the oil every 2500km and immediately after a track day and I only use AMSOIL turbo formulated synthetic with an oil cooler. Vven with this the oil temp sometimes hits the end stop. When I do the fuel pump regulator and injectors I will post the results after another dyno run.

BTW I still havent had a response to my initial qusetion surely it cant be that hard a question.

so what did you gibson guys make with the stock turbos (on the factory boost leve)?

Oh... thats right... you were using steel wheeled turbos and not the ceramic ones

my bad

Considering the only comment Nismoid made was in regards to the fact that 280wkw on stock turbos and stock boost is an unreasonable figure, I think boost level is quite relevant. Or is it just that in your 15 years in motorsport you never learnt to read?

And isn't the statement "rwk is all that matters, nobody races dynos" a bit of a contradiction, since every dyno reads differently. I would have thought it was rwk(w?) that meant nothing, and that it was all about Lap Times and ETs? Or am I missing sometihng somewhere that says if you run a 11s pass with 400rwkw you're obviously faster than the guy who ran a 10s pass with 380rwkw?

SK, I have just ordered a nismo fuel pump and regulator "as pictured" along with a set of nismo 600cc injectors to strengten my fuel system and be in a position to upgrade to r34n1 turbos or other low mounts GTSS maybe for track and targa.. I have a standard R33 GTR except for apexi powerfc and boost controller which made 283rwkw post an exhaust change. My question is after fitting the regulator do you maintain the standard pressure as it now "guaranteed" or should you increase it and if so to what pressure.

I also call BS on 283rwkw with stock turbos. I've seen 250 odd a number of times. Doesn't really matter anyway unless you are trying to tell us that it's for real. It's only useful to you if you keep using the same dyno and operator as a comparative thing. I personally try to avoid dyno's that are known to give inflated figures because I would rather know the truth - or as close as is possible given the known drawbacks of dynos generally.

That said, with 600cc injectors and the turbos you are thinking of you will be fine to keep the stock fuel pressure.

seems like that dyno needs a tuneup!

It was done on shootout mode. Should be fairly acurate. My guess is that the blue line is stock boost, and the green line is considerably higher than stock boost. Was probably tuned on high-boost because if the temptation was there to raise the boost, then you wouldn't need a retune.

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
