Yes we did, and you could be onto something there
either way they worked and worked well! It would be interesting to back to back a CEA of the same size, but after spending 10 grand of my own money on Precision turbo's, I might leave it for one of you boys to step up

62 vs 65 was on a 2.6
It's actually 1.5mm, the "65" measures 64.5mm. Noticeable on the dyno, not so much on the road,
Don't panic, you're 6466 will be fine
-
On my car I have had a 6265, 6765,6766 and 7175. I have witnessed a 150rpm difference between a 6262 and 6265, hardly noticable, but there was also a couple of hundred revs between the 65 and 66 turbine wheels on my own car.
Yes it picked up 30hp atw but the point I was trying to make was, PTE marketed the same if not better response between the CEA wheel replacement wheels of the 65. Maybe that is the case with identical sized wheels, but from my experience not a bigger CEA vs smaller wheel. You can physically see the difference in the thickness of the older wheels.
-
That depends on your combo, on mine the 65 and 66mm made a noticeable difference on the dyno.
-
FYI both 6262 and 6266 are rated as 700HP items. I'd be chasing that 66 CEA item, better tech is where its at.
The 6262 is 700hp and 6266 is 735hp.
Don't be fooled by the CEA crap, the wheel sizes have an influence over response, and the 6262 is more responsive.

Kat, you were lawn mowing at Temora?
I'm in on this now too (only just) now that entries have closed. Can't wait for this, it's gonna be intense!!
-
Here's a clip armed with the 7175. Lost a bit of power with the changeover to C16 but there's more in reserve still...
-
Brad, they make that at all four on a GT-R without a doubt
-
Dude that car is beautiful. so much fappage from all the QLD boys with me.
Thank you
-
Not enough to get their jackets off!
Haha Royal Purple girls are all class!
please oh please someone photoshop a tractor inplace of PJs S13
As long as it's one from the euro tractor pulling comps
-
Well basically, they prefer SR20's
-
A 6766 on a 3L would be a real buzz on the street, on my engine it was still lively, nothing like a 6262 but the lag was worth not getting top ended
I'm ready for some more lag now
-
PJ, what have you seen the 6262 and/or 6266 go to power wise?
Will the 6266 crack 500?
A 6266 will crack 500rwKw all day on an efficient engine. A mate of mines car made 491kW on a plain jane GT35 with .82 T3 housing, then went out and ran a trap speed of 147mph, 1400kg car including driver!!!
Yeah that sounds more like it Lithium, 900whp is a MASSIVE number given the size of the compressor and turbine wheels
My 6766 peaked at 853hp on Mainline at 42psi, running it any harder may have just caused drama's so we called it a day.
The yanks have gone very fast with these turbo's no doubt, they also have the cars setup to take an absolute pounding. I believe they have gone as quick as they have without any GST on the story, I still find it amazing how they are going 145+mph on FP Red's though.
-
Come on lean on the boost already. lol
What in the precision range would be good to replace my old garret T51r with 1.05 rear. Engine is a 26/30 and currently makes 475rwkw @ 24psi thru a auto
Which box is it exactly? I'd be more inclined to go a 6466 or 6766, if it's a power sucking C4
They are rated at 900/935hp. -
Nice one Jez!
-
4. Tomei did back to back testing - split pulse vs single entry and tuned length vs normal runner manifolds in every possible combination and the results were basically nil gain or so minimal it wasn't worth the extra coin
Well, from my experience twin scroll vs single entry = two world's away, every single time.
We have back to backed a Trust twin scroll single gate setup vs 6boost twin scroll twin gate setup and it went down like this.
Test mule was an SR22DET with T78 kit, wouldn't come up onto the converter even after 20 seconds. Changed the manifold and fell over when after 4-5 seconds it had 20psi and the gates were open.
No other changes, true story!

I challenge you to a lag comp next month, Dave
-
It's entertaining sitting here and watching the results do the talking.

Best mid frame turbo hands down!
-
-
That was the old engine/turbo combo, this one had almost 100kW more atw last drag battle
Will separate if need be...

I've decided to go bigger again and move onto the 7th turbo on my car!
Complete bolt in setup for S13/S14/S15
Whole setup has less than 1000 km’s on it and half of that was used to bed the engine in.
Precision 935hp 6766SP BB .84 divided housing as new, V-band rear + oil drain flange
6Boost Twin scroll divided manifold with EGT bungs (EGT kit not included)
2 x Tial MVS 38mm wastegates
2 x Screamer pipes
Big black lightweight braided Earls oil return line with fire sleeve (this cost nearly $300 to make alone)
Produced 574kW (758hp) at the wheels on a conservative street tune & 36psi and ran [email protected] on E85
Starts pulling from 3000rpm, hell breaks loose at 5000rpm.
Made 636kW at the wheels on 42psi on a race tune on E99. Will get into mid 8’s.
If you wanted this for a DET, 6Boost are able to cut the VET flange off and weld on a DET flange to suit.
Must go bigger to support my addiction. $3900 firm, will post at buyers expense

You'll close to 450kW at all four on yours Jez, if the bottom end will take it
either way they worked and worked well!

That's what happened in my case
