Excellent work and congrats on the record runs. Highest I could find for 2530's on a GTR after a quick search is 501hp@wheels in an R33:

The Phoenix runs are on a 4WD chassis dyno.

But anyway, how can you possibly lay claim to the world champ 2530 title without a fight? However, you'll get your chance at WSID on April 9 when a special guest is flying in to defend his world title..... Ladies unt Gentlemen, I give you (drumroll)

Would love to know if those Japanese/English/Australian power figures were on chassis dynamometer???

Timing was an extra 4 deg for that run.

anyhow...how awesome was it 2rismo....your reaction on the video was priceless. Can you host it somewhere, maybe when you get back to work (dial-up boy).

In the Dyno shootout comp. yesterday, TWO.06L recorded a mind blowing 627bhp.

which is 467kw. Is this a new World Record for a GTR running 2530 turbos, or for that matter low-mount turbos alltogether. Jim from Croydons is sure it is but we would like to find out for sure. By the way nitrous-oxide running cars do not qualify and must be running on jap pump fuel or equavilent.(we ran VP 103)

That is absolutely mind blowing and congratulations.

Can I ask how you can get 600hp turbo's working well over their designed limit.

Don't get me wrong but my understanding is turbo's are rated for X amount of power and your combination exceeds the 2530's capability by miles.

Just wondering how it's possible. I understand if you don't won't to give away any secrets but could you provide a broad explanation on how you achieved it.

I don't wish to take anything away from this great achievement I am just really interested to know that it is possible.

Cheers

Great result!

If you have std diff ratios it looks like you're well over the 9 grand mark at the top of fourth? What rods and crank are you running?

Cheers

Don't you remember us Gav.....we are the ones who do cryogenic treatment. The run was to 8000...our redline is 9200. The rods and crank are stock and our diff ratios are too.

Thanks for the congrats.....well it goes a little something like this.......HKS rate their turbo for the worst possible senario. eg on a stock engine using poorly designed manifolds and dump pipes (stock), standard head,cam timing,intercooling,piping etc.

The more efficient you make any of these pieces of the equation, the more efficient the turbos will become (minimise the losses in the system) Every part of our set-up has been thououghly examined to see if we could cut/minimise the loss and therefore increase the turbos efficiency. Correctly selected camshafts, portmatching of manifolds, and CORRECT porting of head play a crucial role in this.

The velocity of gas flow in the turbine side of the system has to be taken into account when porting a RB26 head, we believe we have got this part of the build spot-on. Too many times old school principles have been adapted to RB26 or for that matter any modern turbo engine build-up and the results have not been forthcoming.

HKS 2530 turbos are designed to be efficient at between 1.4-2.0 bar the results on the weekend were achieved using a lowly 27psi. I think in my own mind that their HP rating should only be used as a guide and not as a maximum figure. As a rule of thumb calculate at least 10-20% higher if you do the build correctly.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
