These results give me a little tingly feeling in my balls thinking what the -5's will be like on my 30/26. Obviously provided it's setup as brilliantly well as yours is.

Hats off to you for your perseverance with it! Now the fun begins (driving it!).

Enjoy!

I think you need a 4wd dyno to do the final power output.

Do you know how much timing your running?? not sure if you know, when running tight squish you dont need the timing and if you put timing in it does not like it and what AFR is the tune to under full load?

I can't answer that Bobby. I will find out specifics later on as the tune is not finished. it only had 9 runs or so. I dare say the AFR's will be a little richer then what you like ;)

As for 4WD dyno. Wanna spot me a run up on yours? :P

Was lucky enough to take a mates 26/30 for a belt in Melbourne with dash 5's built by rp

300rwkw at 3000rpm

You will love it

A fair bit of thought went into it all. I think the interesting thing is the cam duration. They are not massive lumpy grumpy things!

Having seen a sorted 30 with 5's on the same dyno.... providing it's sorted, you're in for something special ;)

What is the deficit going from rwkw to awkw in your experience Bobby?

300rwkw at 1400rpm less than Paul's is insane!!!

Didn't your mate Deimar do a test at CRD one day and there was 2 KW in it?

that member repetition looks to be a virus - i saw the same thing a few pages back.

sorry paul, ive even tried to edit my post & the site wont accept which is odd.

not sure about diemars experience but i did get some figures from crd when i asked him a while ago.

i'll try again clean up that shitty post of mine

were your cams dialed in?

Zero zero... We only did 9 runs from a totally new ECU and that's what it spat out.

They will have a tickle this week to see what it does. If it takes away from the midrange I don't want it!

I mean when the motor was build! since the cams are custom, its why i asked if cams have been dialed in to find zero? if not, i think its a good idea to know where the cams should be before playing with them

We know where they are at zero zero. Yavuz set the loves up where he thinks they should be.... Not to say a degree here or there might make the difference.

Lets see what next week brings ;)

Geeeez looks like that port work on the head is doing the trick...

Who would have thought HKS knew what they were doing :/

But did they? its had the super special cams and springs changed in....

Edit: of course they know, but is it better than something that could of been done locally, as yavuz deemed it necessary to make these changes

Its hard to quantify any gains from port work without doing back to back tests. You really need to do a stock head with all the same bolt ons. Then try a worked head with all the same bits and compare results. However, not many people actually have the time or money to try that exactly.

Everyone gets tempted by changes when they have the engine apart lol.

Well nothing changed apart from the head, cams and an extra 0.5mm on the pistons. ECU did but meh

    • 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".
    • Just wanted to unearth this and post my baby with the new front ❤️😝 Took her to my wedding rehearsal today. Next up is getting wide skirts (after wedding)
    • 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.
    • 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.
