I'm only guessing but surely that run was done with an engine dynomometre . Its easy with a well set up one to create the sorts of engine loads that are impossible to sustain in the real world . High figures would not be hard to get with that engine at a constant rpm/load ie no acceleration losses .

Just on HKS's T51R series turbos , don't forget their GT42 turbines use a smaller trim than Garrets same family turbos (GT4294R/GT4202R) ie 76T vs 84T though the housings are very different . Other turbos such as Garretts GT4088R and the more recent GT4094R are getting up with the T51RKAI anyway . Ask Full Race Geoff what he gets out of GT4088R's .

Cheers .

thanks Disco, one of the other thoughts i had was maybe they plotted Hp/ps instead of kw by mistake.

150kw @ 3000rpm

450kw @ 4000rpm

660kw @ 6500rpm

That looks pretty impressive to me. What do you guys think? Could this be off an engine dyno not a chassis dyno?

Anyone have much experience with the Kai? They seem fairly popular in the Uk.

Merry Christmas

These are ENGINE FIGURES, not rear wheel figures. Plus they would not be running pump 98 with 2bar boost.

And it certainly wouldnt outperform a T04Z in "every way" as the the 0.86 rear t04z would be a more usable street turbo than the 1.00 rear t51.

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Could be falling edge/rising edge is set wrong. Are you getting sync errors?

      Jacks that fit under GTR lips that can reach the subframe?

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
