ZZP has a supercharger dyno, and they do it, so i copied them. I would guess that because its basically a lip that sticks out from the wall of the supercharger, so the rotors are basically pushing air right onto the lip.Originally Posted by WHT98GTP

I know the aurora came with a 3.5 and a 4.0....

Technically i dont think there was a northstar in the aurora. at least not according to wiki.

That motor wasn't a N*. It was a V8 exclusevly made for Oldsmobile.... Thats why it didnt come in any other car...

the 4.0 was a northstar. everything about it was northstar. IIRC only difference between it and 4.6 was either the bore or the stroke. everything else was the same down to the cams IIRC.
It was not an exclusive and IMO GM should've shoved it into more cars. the N* is an excellent motor when maintained well.

I'm interfooled and i never bothered with the H bar....
I can't see how the air that is directed towards the front of the motor is going to magically move towards the rear just because of the H bar being removed.
I do see the purpose to the H bar though.
Especially on Gen III blowers.
Prevents pressure from building on the backside of the case needle bearings.
Edit: this is defeated when running an intercooler though.

:-) I stand corrected.

You do good work. I finally got it prepped and ready with the new needle bearings and some inlet work. I also took the time to smooth the remaining casting flash in various spots and smooth the ramp going up into the rotors. I can't wait to get it installed this weekend
I'm gonna have a spare case after the swap. I'll need to do one and post it up.

Anyone ever done a test on what the H bar is "worth"?
Also... damn you and your jinny vee Pure... haha.

A gen 3 I did a while back:
Can't wait to do my Gen V!!!

Ok, so here is what I just got done doing... Tried to replicate the most popular cut... Still not fully finished... and I am undecided about that damn H-Beam... LoL

What actually is the purpose of the H-bar thing?
08-12-2011
Seems to isolate the back of the rear needle bearings from boost preasures... thats about it from what i can gather...

Most intercoolers have larger inlets that extend past the h bar. With that bar removed, you open it up to more surface area of cooling.

Anyone ever tested the effectiveness of this?
I can't see it making much difference.

When did you do this? It's not on the GS now is it?
