Looks like the silencing slots were left alone, as well as the inlet edges of the s/c. Have you installed the parts yet? Im not sure those moddified manifolds will clear the fuel rail.
And i dont see any throttle body in the pics.

I think he is talking about the inside of the line pipe where the TB mounts. It looks like they did a little work on the left and right sides. They didnt take out the BIG hump from the line pipe like BDJ did.

Look at the triangular shaped outlet of the s/c and notice the 2 slots which are at an angle to each other. Thats them. When i spoke with Endyn they suggested filling these in as they are just there to emiminate sound. In other words the s/c will be louder without them. But considering you would have to remove the rotors to properly weld in the slots then port it back smooth it might not be realistic for most.Hey MD, did your manifolds end up fitting ok?

MIDO over at MBWorld has the right idea.

Did you check out the composite intake runners with dual injector bosses? I wonder if he is going with duel fuel systems as well? Sort of like Nelson Racing's octane on demand.
Nope–check that last sentence, it is 1 common fuel rail.
I'm curious how the FMIC is going to work as well. Once it's all done I'll ask him to let us know his AIT temps vs ambient.

I expect that you may see some improvment over 20 psi vs stock. As far as ported heads and other clean up i expect that is where most of your new power will come from. a rebuilt super charger, ported heads and other stuff reworked for 3200.00 not to bad as far as cost. however $3200.00 could have bought a nice turbo or a eaton 1900 tvs.

Re: Supercharger Upgrade
Finally, I got the car all back together. It feels good, much faster based on the butt dyno. I do have some cheap a** street tires on right now, so they break loose pretty easy, up to 50mph or so. I hope to get to a dyno in the next two weeks, I will use the same dyno/dyno operater as before so I get a true measure of what was accomplished, if anything .

Re: Supercharger Upgrade
My butt dyno has seen better days. It's lost all sensitivity or needs recalibration. Lately I use the blurry vision metric. You have to know were all wishing you a huge success for your efforts. Besides, it's easier to be a follower than a leader. But I only follow the best. Be the best!

MD has a pretty accurate butt dyno but depending how long he has been without the car it might need a little calibration too. LOL.

No the drivers side rubbed the fuel rail, i had to heat it and bend it in some to make it fit. I didn't like the unequal openings so I am reinstalling the needswings mani's. I'm hoping to get on a dyno this week ( I'm going to call for an appt. tommorow, closest dyno an hour away ), and hitting the track on Sunday.
