140rwkw is normal for those mods. Some cases have seen 155 with aftermarket pump and reg and boost at 11 so I would not be concerned.

I noticed someone mentioned tyres slipping on dyno rollers.....bwahahahahahahahahaha!!!!!!!

I just put my car on the dyno, running stock exhaust, AM pod filter and 10PSI, with faulty coils and pulled out 150rwkw  <_<

Okay so dynos arent the same, cos i made that figure (or at least a bees dick away from it) with only 7psi.

i drive an r33 gtst, i've got a 3" turbo back (1 piece dump and front pipie), fmic, pod running 10psi.

im not sure what to expect.. maybe around 150rwkw... is that realistic?

would a dump pipe with the exhaust and wastegate seperated give me better power?

ive heard about 3.5inch cats with 3" reducers.. would this also give me more power?

im thinking of getting a t3/4.. would i need bigger injectors and aftermarket ecu or could i just use an safc2?

sorry about the hijack. its all relevant! :D

From every source I know, 30% loss through the drivetrain is commonly accepted.. so 200atfw = 132rwkw! Of course, the 33% may be more acceptable in typical passenger cars, not sure about Skylines and such that are more likely to have lower weight drivetrain etc in stock form

I wouldn't worry so much about the figure, dyno's are only a tool for tuning. If it's tuned properly a car will still run the same time where it counts, on the big black strip! Regardless of hp readings.

That said, every dyno is different. I know of a S/C BMW that pulled higher readouts before and after on the owner's "dyno" that he used than it did on the workshops.

Before it was 10kw higher at the wheels.

After it was 40kw higher. I've seen both the dyno sheets. Same car no other modifications. You can bet which one the owner always claims it makes.

That said, your runs are in 3rd gear. It'd be interesting to see what power differences people are getting with 4th gear runs or their 1:1 gear.

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      No, you're wrong, and you've always been wrong about this. The Nismo has 2 sets of openings. One is a real 2-way, and the other is a 1-way. There is no 1.5-way possible with the ramps that they offer. A real 1.5-way does exist. That Cusco stuff I posted is a prime example. If the forward drive ramps are, say 55°, and the overrun ramps are, say, 30°, then you will get about half as much LSD effect on overrun than you do on drive. It is real, it realy works. OK, you're slightly right. The Nismo has 55° and 45° ramps on the 2-way, so it does offer less LSD effect on overrun. But, I think that just means that they've (probably) sensibly established that you do not want actually equal LSD effect on overrun. You just want "quite a lot, but not quite as much as the drive LSD effect".

      Nismo GT Pro LSD configurations

      By Kinkstaah · Posted

      Yea, that is what I was getting at in my ramblings too. The nismo one actually is a 1.5 way and a 1 way. They don't do a *2* way because a true *2* way would have equal ramp angles. Or is that a true 1.5 way? Realistically I think a "1.5 way" does not actually exist. A diff can either lock in two directions or one. It also doesn't help that a LOT of people in Australia speak about 1.5 way diffs are referring to their 1 way diff.

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.
