Sound clip - m90 on 305 TPI
The other thread was getting long so I started a new. This is a clip I recorded just this past weekend of my brother's car with the m90. I wish I still had my camcorder but this will have to do for now.

Hard to tell just by riding in it but I'll go out on a limb here and say its a little faster than it was before 
Ya, it pulls pretty good. It was nice for me to finally get a ride in it after putting hours into the thing.
Our next goals:
1) Get it quieted down. I'm pretty sure the noise is coming from air screaming through the intake tube. If you think about it, on the Supercoupes and GP's and such, the TB is before the SC, therefore its not sucking all that air at idle/cruise that this one does. I'd like to route the bypass valve outlet to the intake and see what that does.
2) And get more boost, duh. There's a few ways to skin this cat, but I think it can be done without going to extremes (we're talking 6-7psi, nothing huge).

Heh… I warned you that it was going to be loud… I wish I had a sound clip of my brother’s car, he’s running a lot more rpm then you are and his whine is much worse.
On the factory setups the whine is deadened by the actual TB blocking it and by the air filter/air box design and location.

Ah..... sounds like an Eaton to me... 
Yes it does get annoying after awhile... especially with two.
Getting much belt dust yet? Bob

My GTP was quiet with the factory air box they designed that to make it fairly quiet. Now that i have a fender well intake its pretty loud. I have people comment on how loud it is all the time. The M90's are loud when you have no baffling to quiet it down.

Eh...there's a little bit, I'm guessing it's not completely lined up, but it hasn't thrown a belt, broke one, squeeled or done anything else unnormal.
