Lets hope she hooks and yes less breakage this go around.
When I got the rear diff pulled apart, the cross that the spider gears fit onto was completely disintegrated...and appeared to have been that way for a while as none of the broken edges were shiny or "fresh" like the rest of the broken parts in the diff. I'm willing to bet it broke previously with one of the broken axles...so it's been hurt for a while. Should be much more-reliable with the new rear diff in there. ;)

Where did you buy it from? Google has no idea about that part number in regards to holset compressors. Can you pm me the link?

Any idea on flow rates vs a hx40?
More, hopefully....otherwise, no. :p

Thanks for this. :)

After reading your original post about this new setup I looked into KTS and spoke to a guy named Dong, who is the North American Sales rep, but he wasn't sure which compressor wheel I was asking about. I couldn't find it previously in the catalog either, so this will really help.

Might just be what I decide to go with for my new setup.

Thanks!

Explans a lot with how the car performed.
 
First outing on the new turbo, we seen 75 lbs/per min at 35psi in first gear, the car ended up blowing another rear diff before I could make it into 2nd gear, so the turbo is definitely moving way more air! And to be honest I couldn't tell if the turbo spooled slower, felt the same as the standard hx40.
 
I believe the absolute MOST airflow that the old 6-blade saw was a momentary 72 lb/min flash at the very top of 3rd gear at 40psi. To put this into perspective, I believe Dave said the log of the 9.12 @ 158.5 run last fall yielded either 66 or 68 lb/min, however the air was super-cool that day.

SO....in first gear, when engine load is practically nonexistent, and not even close to redline the turbo logged 75 lb/min at 35psi through the same calibration that was used on the previous HX40. With more boost and a higher load factor, I don't see any reason this turbo can't flow into the 80's. :D

Wow! That's serious...OMG Like you say Justin, 75 lb/min in first is no joke. :| I can't wait to see more from this beast. :D

impressive to say the least.
 
That's not particularly surprising given it's got basically the same size inducer as my standard HX52. Even last weekend I was seeing just over 70lbs/min @ 31psi by 9k on some pulls with ambient temps nearly 90F and humid as balls.

I would be surprised if you guys couldnt creep past 90lb/min when the car gets to go out on kill mode.

Compared to a 60mm of similar hub dimensions, a 67mm turbo has roughly ~25% more cross-section to draw the charge through.
 
Just an update- backed the boost off a little in order to get used to the new clutch in the car...getting prepared for the Shootout and the local IFO race that follows.

Ended up cutting a 1.46 60ft (new personal best) on route to a 9.30 @ 149.75 on just 32psi last night with the new turbo installed. :D
 
So, Justin, you used a HX35 chra and compressor housing and BEP exhaust housing and then machined both the compressor and exhaust housings? Why not start with the HX40 compressor housing? When I bought my first Holset it was an H1E and had that same odd turbine and was bummed to find out it didn't fit in the BEP housing. This looks to be a really different and cool setup, hope you guys get great results! Love seeing Holsets running, and beating, all those expensive turbos out there.
 
Whats a rough ballpark figure of the price on a turbo like that? I mean a holset that can flow over 70lbs/min and its NOT a monster 52? Thats fn awesome. Any other turbo in that range is gonna cost over 1200 minimum. BB? 2200 roughly or more?

That's insane! Can't wait to see that joker at its full potential:thumb:
 
First pass attempt, didn't have my footing right on the clutch peddle resulting in a super bad launch.. But anyhow was trying a new helmet mount for the gopro, and I really like the view!

Always awesome to see this car killing it at the track. I have the 67/67 setup in the hx collecting dust. The GTR and Evo builds drained my time and pockets. You guys are doing some ridiculous numbers. Also I hear you're in CA now Justin' welcome.
