New precision 6466

[yamadjs08]

Curious, was this with divided or un-divided housings? What AR?

Craigs manifold is divided, correct?
I'm about to order one of these, but can't decide between a .81 un-divided or a 1.00 divided housing. I have a T4 divided manifold...

ditto

Craig has an HKS divided manifold. This turbo makes killer power for the size.
The 81a/r seems like it works the best out of all the housings according to SP.

[Craig Bush]

^^^ correct!

fwiw, i would get the divided housing so that if you ever want to swap your manifold for an undivided and then use the QSV, you've already got the housing. but i don't see availability being a big deal, so you could always swap the manifold AND housing later if you want. 6 of one, half dozen of the other really.

Turbo made 950 on a Evo with a 2.0 at 50lbs Very Impressive

[SupraTTR]

Good thing I didn't jump on a turbo yet!

[myMUSICveins]

Would these turbos behave differently at pump gas levels or the same spread of power should be expected? Also does it make any sense to use a QSV even if going with a cast manifold, or are those only ideal for a divided tubular mani?

I have the 6766. It will be sitting on a non-divided manifold. What AR are on these turbos. I have a .81 for a quick spool. I know I'll need a different one for more top end hp. But I'm looking for something that will get me down the track fast with out the use of NOS.

SP is selling the QSV as an option on the Torque monster cast mani kit, so that must make sense.

I'd also like to know if lower boost/pump gas build still favors a 6466 over a 6266, or not so much?

Great info

The motor was meant for the R33 GTr I have been building. PACNW nationals came and the owner bought a r34 that had a mishap on the dyno.. we worked for 48hrs to get the new motor in for a show.. (you can see the results of rush) Car hasn't been fired up yet, we are redoing alot of things and Cleaning it all up..

Numbers should come in the next month or so.

I will post my graph or have Reid post it after SP F1 manifold qsv valve with the 1.0 divided 6466 are installed in Oct

Hey, did you dyno your setup yet? Any feedback on your street driving? Curious to see how you like the 6466 w/qsv on a tubular manifold with a 1.00. Pretty much how I'm considering moving mine towards, but with a 10:1 comp ratio and a hypertune

We're a bit behind at the shop so Neal's setup hasn't been finished yet. I'm definitely looking forward to the results!

Awesome, thanks Reid for the response. Have you guys done a 6466 on a QSV yet with a tubular manifold?

[K_SHAN]

6466 with that housing and Qsv.. Thats gonna be a very interesting setup lol


*updates on the r34.* Fab'd new Ic piping and few other things.. Just waiting on John reeds patch harness for the Motec.

I just received word that a 6466 on a cast manifold on ProEFI and E85 made a tick over 900 rwhp on a dynojet in california!

Very keen to see how that goes!! Particularly interested in seeing how the higher compression RB26 combo works

[K_SHAN]

this is our very mild rb26..

We are in the middle of a building another, Higher compression and alot more turbo, and 3.0l....

In for more news!

[nosechunks]

Now look at this next dyno on Reid's car, the 64 out spooled the 67 and made more HP showing that when inits efficiency range it outperforms the 6766, not until we went all in like on Craig's car did the 67 make more HP.

What were the turbine housing A/R for each of those turbos on Reid's car? We're they all the same? We're they all ball bearing?

Thanks,
Dan

[Sound Performance]

.81 a/r. I think they were all bb not that it really makes a difference

[nosechunks]

They were all .81?

Yeah, im lookin at the boost curve thats why im asking about the ball bearing option.

This is a sick dyno comparison, Thanks so much!!

[GT_Ridaz]

I mighht get one too

[nomolos1]

So in other words, the 6766 is a waste of money, if it can't make more HP than the 6466.
