Holset HX40 spooling

Thanks, good to know.

Measurements from the 2 CKO HX40s I bought are in this thread.

That is a nice downpipe. I might be having one coming but I still think it would be REALLY laggy for me. Especially since I think my 12cm HX35 with only a 54mm inducer has trouble spooling sometimes. Yours spools way fast. Even faster than my HX35. But Im sure having an auto helps you. But still. Im really leaning towards running a 12cm housing on it. I checked for sure, and like Pacific said, the backing plates are different sadly.

That's too bad the backing plates are different....I would have enjoyed seeing back-to-back tests.

Are you talking about the CKO vs the real one or ?

Why not a diverter valve again?

Real Holset. And because I dont have one, and dont have the money really for one, or the time to install it, and they don't make a T3-T3 diverter valve. My turbine flange is T3. They only make T3-T4 and T4-T4 really.

Good reasons.

I made my own valve. Soon to go on. We'll see if it actually works

I've been waiting to see this thing!

 

[6.5L]

Yes, do let us know how it works

IMHO running a manual trans on DD a blower would be far better option over any turbo period.

Well I went ahead today and built the hybrid. HX40 compressor wheel. Rest of it is 35. Although to avoid any machining I simply took the turbine wheel and shaft out of the 35 and put it in the 40 bearing housing and swapped my 12cm 35 housing to the 40 bearing housing as well. So if need be I can always swap back. But so far I love it. Gobs more torque down low.

That's cool to hear! I'm glad to hear you're liking it.

I like my hyrid too. Are you doing any backpressure tests?

 

[6.5L]

no. No equipment for it
