I am not sure of what combo he was running at this time but he got into the 8’s. I’m sure he will chime in.

8.77 was done on the 66mm HX40 as you see it at the beginning of this thread, paired to an ERL manifold in the .70 BEP housing. The manifold/turbine housing setup has since been upgraded as we definitely reached the end of what a .70 a/r housing could do for us at 160+mph.

Been trying to work out some rear differential mounting issues but once that's solved you can expect big things. Every pass made this year so far has mainly been low-boost for tuning....I don't even know if we've been north of 35psi yet this season.
 
Custom topmount with a .82 Garrett housing. If that doesn't work it's getting a 1.06 Garrett housing...but I need to find a way to fit a GT35R turbine housing to it if I want to go any larger which will require a custom spacer like FP uses on their Super 94/99 turbos when running a GT turbine housing. The only 1.06 T3 housings for journal bearing Garretts are twin-scroll, and I don't want a twin-scroll housing.
 
Just curious if anything made you choose the Garrett turbine housing over the others i.e., Tial, etc., etc., assuming fitment is a non-issue (custom manifold/machining/spacer) but from a performance standpoint? Which specific style Garrett housing did you end up deciding on?

I’ve always wondered how some of the newer design .82 housings stacked up against one another, but I have been unable to find good data/comparisons and from a broad range of manufactures. I did see a post from a Garrett engineer regarding the GT3582r where they claim the performance of their old school .82 T31 housing (2.5” outlet) was slightly less on the order of “the uncertainty of the measurement” than their new GT housing and thus suspect observing no real performance difference. Notwithstanding that claim from Garrett…I’m skeptical.

It’s great that you’re experimenting with this and I love the car. I hope the .82 Garrett housing works out for you guys!
 
Also if your selling any of the setup that you've outgrown please keep me in mind and PM me.
Take a number. :p

Cost/availability. I had the housing I wanted to run on the shelf and didn't need to buy anything else- just needed to get it machined...and he had the T3 collector already built for the manifold. Sure beats the hell out of spending $400+ on a TiAL turbine housing.

I don't know what you mean by "style"....it's a .82 T3 housing with a 3" v-band welded to the outlet.

To my knowledge, there's not a faster T3-framed journal bearing turbocharger anywhere on a 4G63-powered vehicle. This thing's actually gone faster than the fastest-known 35R-based turbo on a DSM (that being a FP HTA3586) back when it still had the .70 BEP housing and ERL manifold...basically all stuff that anyone can buy and install, no custom fabrication. Obviously now that's changed a little.

Still quite proud of a turbo I designed and built myself to have done so much and gone so far based on brand that nobody thought was worth a damn as little as 4 or 5 years ago. To those folks, I'll quote Daniel Tosh- "Na-na-na boo-boo, stick your head in doo-doo." :p

Regarding style:

For example Garrett makes more than one “style” 4-bolt outlet .82 T3 turbine housing. They are commonly differentiated and referred to as “T31 style” and “GT style” housings. From my understanding “style” connotates the discharge diameter and which wheel technology the volute was designed around.

Moreover, “Ford style” is commonly used to identify their old school 5-bolt outlet T3 housing and there are many many more “style” housings…

Here is what I’m meaning/asking: when you say you are running a Garrett .82 T3 housing with a 3” v-band welded to the outlet, I am left to wonder which “style” housing it was originally; was it a 4-bolt outlet, T31 style housing (that has been modified to accept a 3” v-band) or was it……?

OR, what was the original turbine wheel in that housing? What was the original discharge diameter? And what outlet was in place prior to welding on the v-band outlet?

Here is an interesting read on the topic of T3 .82 housing comparison and results that you may not have seen: http://www.evolutionm.net/forums/ev...386799-buschur-s-dyno-testing-never-ends.html

Great job with the car and turbo(s), definitely something to be proud of…I hope this new setup kicks ass. You are the oracle of the Holset brand on this platform for sure no question! Lol.

Wrote this all quickly, hope what I’m asking is clear.
 
Well it's not a GT housing- as stated above, those won't locate the turbine wheel into the volute without a spacer. It's a .82 T3 housing from a journal bearing turbo. I think it was previously a 4-bolt outlet. Like I said, I worked with what I had...I didn't set out to find the "ultimate" .82 housing or the budget would've been much higher. If I need more turbine flow, I'm going bigger...I'm not screwing around with other .82 housings in hopes that they'll give me 1-2 more lb/min of airflow. You're giving this much more thought than necessary. LOL
