Can somebody give me a Cummins part number for an 8 blade HX40 with 12 or 14^cm housing?
Billet wheel as well?

Im looking at a Holset for a friend of mine and i have question, the holset i found has a vband connection for the compressor housing, will that still work on a Dsm.
^^^^That car sounds amazing!!!! I love the 3.8L. It so makes me want to finish my fathers GN/holset project. . .
I think he is talking about the comp cover connecting to the chra.. Yes my wh1c has that type of clamp holding it on.. H** series has v band clamps holding the comp covers to the chra while the hx** series has the c clip.. Make sure you find out which on it is if you plan on going with a bolt on housing..
I figured this might spur up a discussion. Dsm-onster, here is a small H1C off of a 90 non intercooled cummins. In the beginning of the holset threads you list the small h1c's having 7 blade compressors but the one I have here is an 8 blade. She's pretty clean for a 90, and should be well suited for my brother's fwd. Have you seen this particular H1C before?
This is for the hx-35 7-blade with the bep .55 housing guys. First let me say you're going to have to take this with a grain of salt and I'll explain that later.
I was out tunning my 1650 injectors. When I first went out it was around 60'f and was tunning at around 26psi. I went to the "shop" for a while, annd it got a good bit colder (50'f).
Just before I got to my house I dicided to punch it as I turned into my road. This was the result. I hit 57 lb/min at 28 psi during a spike, then shifted and blew a ic pipe after the gm so ignore the small 2nd gear pull.
On to the cons, this was in first gear, for a small pull in much colder weather. But there is hope for these turbos in the small housing.
I've bgeen the biggest pusher of guys running a bigger housing with the 7blade hx35 or just getting an 8blade version, unless you want to go t3 later. I can see topping out the 7blade compressor using the bolton housing being possible. I've always been one to try to help someone get a BALANCED turbo and use other avenues to increase spool speed. But hey, if guys can get 42-45lb/min out of a pitiful 7cm^2 turbine housing with the td05h turbine wheel, then it's definately something that can be done. The BEP housing is so much better than the mhi housing. . .
