Not a Skyline but this is a street engine RB26 (BC 2.8L Stroker kit) with a TH400 box, made 915whp through the auto and 1070whp through a manual on 35psi with a Precision 8285 (1.12 A/R) - sounds better than a mangmang. Cranked it to 40psi next meeting and cracked the factory block like a spider web, the car sadly hit the wall hard. Also as a veteran of this thread I'm putting my PTE knowledge to a bit more use these days, I can help out any SAU Members interested in ordering Precision Turbochargers off my website. www.makemegofast.com

That's a bargain given the dollar!

Finally got the car with new Plazmaman intake manifold and 6870 to the track with an auto though... 9.60@140mph on 21psi 9.39 @ 144mph on 23psi Turned it up to 40psi and the box doesn't want to play enough to head back to the track but it feels very strong. Hopefully back to the track in a month on 50psi.

If you want a responsive 600kw stick with the 6766

How far off are you Paul?

Liking the sound of this! Hoping you're gonna stuff some boost into it!

Driven at least 5,000 km a year Charlie, not daily but at least once a week/fortnight and for a few hundred kilometres when it comes out.

Is there anyone on here who has done lots of road and track km's using an OS88?

So my 6870 will be on the way shortly, I plan to push it until it has nothing left to offer which according to its 1100hp rating should be a nice gain over the 7175. Certainly won't sound as good or hit as hard but that's not the reason I'm putting it on. I would expect it to need at least 55psi to get it to a point where it won't offer any more power. I'm chasing more response and the driveability that the 6766 offered. This is a custom 1.00 divided T4 housing we are using, so it will be a good comparison as the 7175 was running a .98 T4 divided. It packs the goods to run low 8's in my car, I will try and better my time in the coming few weeks with the 7175 through better car setup before retiring it for turbo # 9 and the 6th Precision turbo since 2010.

Just to elaborate on it also man, the car setup has a massive influence over the ET. The car trapped 153mph, that is a very good time for the trap speed. I don't know of the weight, but it's an RB30/26 auto and it launches like a bat out of hell. Pretty sure when I spoke to Justin they had maxed it out, my 6766 showed signs of boost falling off @ 42psi (850whp) and the 7175 is showing 920whp with nothing left. If I was a betting man I'd say that I was at the limit of the 6766's 935hp rating and probably sitting on 1000hp at the crank (7175 rated to 985hp). Only sure way is an engine dyno. Rather wear my engine out on the track.

Ryan, absolutely impressed with that result, as I was with the STM Ricer at 2850lb and 8.75@167mph!! And I'm not having a dig at what the cars have achieved, only how our figures compare to overseas. At the end the day the track is what tells the truth to me. Lith, totally agree, if I was turbo sponsored, I'd be happy to try and push the 6766 to 167mph (ran 154.86 on 36psi). The 7175 is pretty much tapped on 52psi and it went 164, the only thing I can really do is go out again, with more power and the longer gearing it has now 4.11. I think 170mph is possible, high 170's though? Not gonna happen.
