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.

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

^^^ I'll report back when I get mine in.
How far off are you Paul?

I picked up my 6870 on Saturday. Will be going on a 10:1 4L v8 on e85. Keen to see how it compares to the old t04z!
Liking the sound of this! Hoping you're gonna stuff some boost into it!

Define "lots"
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.
-
PJ did you mention earlier that the JW automatic GTR ran 8.7 on a 6766? GST or not that is making some serious power from a 67mm
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.
-
Yeah those numbers seemed high for a 6766 on a Mustang, though I am still shocked that people are taking hp ratings as some kind of gospel. How much did you make atw on your old GT3076R? And what are GT3076Rs rated at?
The 6870 is certainly looking the goods, no matter how you slice it. Would have loved to have seen FPs Super94/99s on more things - they are in T4 twin scroll and imho until this came along the best thing since sliced bread for the ">6766 power without going BIG frame".
Ha, you stumped me on that one, I'm one of those guys. It was a 3037S, HKS rated to 480PS, Garrett 525hp, I made 503whp. In saying that, we pushed it to 25psi with a T2 1.12a/r housing, it had a held a flat boost curve unlike the .73 which would fall from 24>22psi (458whp). Car full weight went 10.4@136mph 2870lb.
The figure for which I base my decision on turbo selection is what the manufacturer rate them to anyway, as long it is capable of making that then it's all good. Going gung ho and trying be superman by making a shitload more that what they rate them to usually means that you're just reducing the life of the turbo in the first place. Hit your goal with the smallest turbo possible by all means, get greedy and you might find yourself with nothing left on your shaft. Hmm that sounds kind of funny...
In saying that, even with their massive claims, the yanks are doing some damn impressive stuff. I'll be ordering a 6870 in a couple of weeks depending on a call tomorrow. 1100hp at the crank should see my car trap 168mph. I'm feeling a bit excited.
-
Keen to max out a 6870! Hopefully they release divided housings for them sometime soon. Certainly looks good on paper, gotta love those GST yankee figures as always
6766 rated to 935hp, makes 949hp atw.

Looking into CCTV, just completed the car and intended to insure it, won't change the situation now

Mates car got stolen from the early hours of this morning from Kingsgrove.
Single Precision Turbo
Please keep a eye out, it is uninsured and sadly will be a complete loss if not found.
Reward for return.

7675 comp covers.
gt42 style vs hp.
different surge porting.
different outlet.
is the 42 really worth an extra $700?
im assuming they would have the same comp wheels.
anyone had a play with them?
It's twin scroll divided housing vs open. GT42 style also has a larger comp cover, that's the difference.
-
It's stock, I used to worry about busting it but I did the Snowy Mountains 1000 and had 5 passes into 5th, certainly reminds you how much you hate synchros when you go to shift in 5th fast.

Helical dog 1-4. I broke a selector after over 30,000k's, and replaced a few bits from it last year, that was 6 years worth of abuse that you've seen on those videos. It's the only way the car gets driven, and I might add that both the guys who work on the car had been learning to drive on it as well.
When I broke the selector it was partially my fault, but most of the wear would have been caused during the initial period of me getting it together.
It does take time to learn though, you can't just jump in one and think you're Fangio, it will bite you in the arse and if you are offered a test drive, you're wasting your time unless someone experienced is in the driver seat. -
Unless you need dog 5th, helical dog 1st-4th is the best for the street because it doesn't make any noise.
After the first couple of months hating life that you just blew a shit load of money on something noisy you can't drive, come and talk to me once that's over and let me hear how you'll never want a synchro box again. Ever.
They are the ultimate.
-
That's good to hear! What turbo were you running and at what PSI if I may ask.
6766 on 42psi SR20VET 636kW. This was nearly a couple of years ago and I'm still contemplating going back to this for the street.
Simon that's great power for a 6262. They are electric to drive on an RB.
-
.84 housing will do 500kW on an RB all day, nothing wrong with the housing choice. I pushed > 630kW atw through mine before I started to see signs of a restriction.
