I have to check the.
I'm looking for large.
What did my sentences have in common with your post? Unfinished.
I.E.: What pressure ratio was the 18000 RPM, 100HP blower operating at? What was the specific gravity of the air you were using?

Guys.
Has anybody as psychrometrically accurately as possible compared blower non ported-to-ported MAP?
If MAP was lower when ported, either the blower can't pressurize as well, or temps dropped.
So has anybody properly measure outlet temps AND MAP?

Mech.
No,
It's a M90 on a 3800.
Won't matter really...it's like comparing a CAI to a WAI or a HAI or an Open Cone.
Can of worms opened, and left open forever...I'm just replying to Matt...because I can...not that it's worth the time.

It's odd that no one waits for the guy that put a post rotor temp sensor into his setup to post. I've also done thermostat testing to see what works and doesn't for stock vs 180 vs drilled 180 etc etc.
Fawk...take a look at how much I ported that Gen 3 in the pics. I damn near went down to the coolant ports.
The research I've done backs up what Matt is saying. (Eh..you can send me that Paypal now)

Blues common sense > logic.
Don't be afraid.

Matt must have wished upon a shooting star.

nick, youre talking about adding a beveled edge to the outlet? what gains could that possibly have over just opening it up to what it should be and giving the bottom side a once over with a wire brush?
05-10-2012
Because all he did was clean it.
He didn't even remove the square bosses at the top of the outlet that protrude into your typical "V" pattern.
So, If I'm wrong...then that means Brian has been doing it all wrong all these years too? I doubt that.
05-10-2012
but he did remove the bosses where it mattered, the triangle is fully extended. he just didnt remove the entire thing.
05-10-2012
Triangle didn't move down at all.
Just removed the little bit at the top...
Maybe we should all do it like Stieg does it and end the discussion?

people are mad. So should i just clean up the arrow or make it a v also im still confused about the inlet of the sc where the tb goes
05-10-2012
Make it a v how i posted mainly all you have to do is cut the two little bumps on the bottom of the V were the bolts go throuh on the s/c case and just smooth out the whole V outlet you can make it just a bit larger the whole V itself even a bit higher but very little just to smooth it all out. look at the pics i have posted. What are you confused about on the inlet side of the s/c case/TB side?
here is another pic

Ha, not a problem. Frustrating being told you're wrong with no rebuttal as to why.
Issue with our blowers is we have the PCV passage right under there. There is only so much we can remove before that would become an issue.
However, how far you can go, I am not sure.
Have a junk case I can play with though.
05-10-2012
It took three tries to get my current setup. Fine balance between making more HP up top and losing TQ down low. All dyno tested of course. As I've said before I'll help anyone I can, if they're willing to listen. I don't know everything there is to about these cars but I know enough about superchargers that I can be a part of the discussion.
05-10-2012
See where my logic gets you?
Somewhere.
Both of you whiners are welcome
BTW, where were the pics of the port you did on your cam setup?
05-10-2012
That's the kinda port job I am going to try out. Much larger outlet. Not fully done yet though.
05-10-2012
the inlet where the tb bolts to the sc case
05-10-2012
Yeah I know what about it you aren't explaining yourself here just saying you are confused with the inlet. So my question here is what are you confused about?
