6 blade, 7 blade, or 8 blade??
 

I've decided I'm gonna spend the $275 on the 60mm compressor housing for my hx35, but I don't know what wheel I should get... 6, 7, or 8 blade?

you need the 40 center section, or your have to have yours lathed out.


also... 6 blade. Your spending about twice what you should on a housing btw...

Its Gillett diesels upgrade, according to them it'll go right on but don't know much about it

HX Upgrade Compressor Housing & Wheel (60mm, 8 blade)

That's the part... whatcha think?

Ah. I see. That should not be an actual 40 then. Just an upgraded 60mm compressor. Since you still have to have it balanced... I wouldn't evenconaider for the money

I thought the compressor wheel was zero balanced itself? I put Gillett's 60mm 6-blade on my H1C on my 1st Gen and just put it on; no balancing it, and the compressor appeared to have balance notches machined into it already hence the zero assumption... :humm:

anything spinning at 80,000 rpms needs to be balanced... lol

what is this supposed yo do for you I have a hx35 on my 93 and it is pullin 37 psi. does it spool faster or give you more boost

most boost at about the same spool.


I would not bother. You can buy a full super40/35 for about the same price.

I cannot disagree with that; it's basic physics. However, not being a turbine specialist, I'm merly questioning what balancing a turbo truly entails. Everything being concentric, I would assume, in theory, that a zero balance of each individual component would net you pretty close to an overall zero balance, assuming true concentricity of the shaft to impeller mounting bosses. I wouldn't assume that a turbine manufacturer would have compensating balance marks across the midsection (relieving the compressor to compensate the turbine imbalance for example) which would create a weird moment of inertia, but I could very well be wrong. Granted, I was new and ignorant to turbo philosophy when I did my 60mm upgrade (I just wanted smoke and cheap power at that time :argh:), but I've thrashed it pretty hard and haven't had an issue with it...yet :w2:

I would really like to see a genuine, quality Super 40/35 for the price of the 60mm upgrade. I would like to have seen it even more back when I did mine because I would have been much more comfortable with a complete 40/35 rather than the 60 H1C...and I probably wouldn't have gone with the PhatShaft 62 I have now :argh:

BAEturbo. complete turbo minus exhaust housing, $495. Bob builds and balances them there. He just does not use Holset housings... he has his own casted. Saves on price where you dont need to spend.
