MitsuStyle - Dave's Evo X Build/The Life of Dave blog

I ran a 1.32 divided housing on a 6765 few years ago it made 30psi by 6500rpm.

If you looking to get the most power of a 67mm there is better options than the PTE 6766.

Divided T4 yes. Borg Warner 61mm. Never ran 20psi through it yet. Hope to cross that road in the next few months. AR is just a ratio though, so it's kind of hard to compare different manufacturers housings just by the AR number alone.

Here is old post of mine showing some back to back tests on a 2.5L Subaru I believe, comparing two different BW turbos (60mm and 63mm) with two different exhaust housings (.91 and 1.0). You can see why I chose the .91.

But again, these are BW housings so not really apples to apples with PTE stuff. And remember AR is a ratio, there's more to it than just that number.

He's going to be running a 62mm. But you said this in my build thread and failed to produce any examples when I asked. Sure there are some that out flow 6766 but most 67mm turbos out there cost more.

The a/r is very subjective. Halon let me borrow his bw to test fit it on my talon. His exhaust housing is a .91 and when comparing it to the .98 housing off of my gt4294. Even though the a/rs are pretty close Halon's seemed quite a bit smaller.

I went with a 1.32a/r on my 6766 and it also looks smaller than the .98 of the gt42. Even though the a/r is quite a bit larger on the 6766 I can't imagine it will spool any slower that my gt42. I guess we'll find out soon.

Yea I wouldn't go with a 6766 if I was going that big, next step is the 6466 for me if I ever get there. The 6266 should keep me happy for this season and hopefully all of next. Plenty to do to the car that doesn't involve turbos after this upgrade.

Well since you failed to ask in your thread but now you did in this thread here you go!!!!

EXAMPLE#1 http://store.forcedperformance.net/m..._Code=Turbo-FP

EXAMPLE #2 http://www.full-race.com/store/borgw...sx3-turbo.html

EXAMPLE #3 http://www.precisionturbo.net/turbochargers/class-legal/details/Class-Legal-Turbocharger---PT6785-CEA®-for-MIR-Super-Street--True-Street-and-OGS-SFWD/500

Also BW has an 11 blade 67mm rated at 1000 or 1050 just can't find it......

Thanks!:bullrider:

For what its worth....
PTE 6765 with 1.32 housing at 34psi made 719whp @DB
BW 67mm with 1.10 at 35psi falling to 32psi made 785whp @DB
Same set up different turbos.

Thats some good info! I'd like to see 700@db if I can. We'll see how the 6766 does. If I don't like it I'll run it this summer and go a different route next winter

Sounds good!

Actually I did ask in my thread. I was looking at that bw and fp. Those are gt42 framed sized turbos. I went with the 6766 based on boostin performance's recommendation to not go with a turbo that large for my goals for my car. They recommended the fp hta3794 or the 6766 (yes the 3794 also out performs the 6766). The 3794 is $2500. that bw and fp hta4294 are $1500 and that other pte one you posted is almost $4k. I went with the 6766 because it was $1050 new.

Sorry for the mini thread jack! I can't wait to see what your car does on the 6266!

The 6466 sure fit nice behind the motor on the 3Dx Evo at Tx2k...

Re: Dave's Evo X Build/The Life of Dave blog

Well, sounds like the new 6266 showed up today at MAP :) They are mocking it up now on a test engine outside the car. It is indeed the 1.0AR housing and after hearing this from Aaron at English Racing I feel pretty good about not going with the .84 A/R:

6466 testing (not quite what you are asking but similar)

2.3 VIII with a SMIM made 22psi at 4500 with a 1.15 vs 13psi at 4500 with the 0.82 T3

Volvo 2.5L we saw 34psi of backpressure at 27psi with the 0.84 TS. A more efficient Evo X would be even worse. Currently that same turbo went on a 2JZ (3.0L) in the same car with the 1.00 housing and was 13psi backpressure at 18psi of boost before we had to stop because of an injector issue.

It would be my opinion that the 1.15 is the best choice but since you are wanting more response than peak power I'd start with the 1.00. Worst case is you have to buy a new housing and then retune.

So he thinks even the 1.15 for the X but sounds like the 1.0 is a better choice for sure than the .84. So game on.

Good choice! Can't wait to see your results when it's finished!

Re: Dave's Evo X Build/The Life of Dave blog

So why a T4 manifold on a 6266? I had good luck with the vband on mine, makes good power and spool is responsive, just my 2 cents. You will like the new power capability!

Re: Dave's Evo X Build/The Life of Dave blog

I debated vband, the AMS kit is vband and is pretty badass. But honestly from what I have seen the t4 twinscroll is even a bit better for response while still being able to dish out the top end.

Realistically, this all came together with the opportunity to work with MAP on making their new t4 twinscroll kit, so that is why I jumped onto it this year (was going to wait for another year of succesful motor running) but it was a good opportunity to jump into the non stock frame stuff which I have wanted for a while now.
