It sounds like everything's good with the family. Congradulations! 
Here are the dyno results with and without IMRC. http://www.photohost.org/gallery/sho...t=7&thecat=500
Check out the dip at 3800 rpm with IMRC on. At 4200 rpm, without IMRC, it crosses over and goes from gains, to slight losses, then from 5800 up it's almost identical. I picked up almost a full pound of boost at the top, to 7.5 psi w/o IMRC, so apparently it flows better open.

Damn... I think I might unplug that HP sucker... but not till I install my boost gauge...
Brad I hope you get your headers soon... I am really surprised by those numbers... and you were running the 6 pounder too..right?
Smitty
P.S. Welcome back Pappy Steve, I hope all is well on the home front..

Nice numbers there, and without headers too!!!
From what I see the difference was negligible as there were variances in areas which wouldn't have been affected. What this does tell me is that there isn't any significant drop and provides the go ahead with the new manifold. And IMO, the new manifold should be more forced induction friendly possibly providing even better numbers over the stock unit.
I'll begin work on it right away as I do think I have an extra piece of 1 inch thick stock aluminum plating.

I was referring to the 14 HP you gained by unplugging it... I guess I will be the little ginuea pig for the 6-speed S/C guys..
I need to call and set appt for Dyno run... these damn people need to stop dying on me here... I am overloaded..
The exhaust cut out is coming together... I bought 2 of every component so I can build 2 Simulators... I have all the part numbers and everything.. Radioshack is suppose to deliver the components any day now... once I put it all together I will head to the dyno...
The exhaust guy is doing a CAD drawing of the Stainless flange and he has some type of software that shows air velocity, so he will know exactly what degree to set the flange at... ALL I have to do is get the sim. done and head to the dyno.. then we will know where the biggest gains of HP come from... I seriously doubt I will be able to fit it before the stock cat.. I think I will need to move the cat back maybe 6 inches.. no biggie...

No problem to make this Intercooler for you...
2-231B with a tank on one side only. You fabricate the rest of it...$625.00 less the 1 tank...
5-7 days to make it....

I'm going to pull the upper manifold this weekend and verify the area available. With that along with the measurements available on the IC I will fabricate the new plenum which will take about a week; just in time to receive the new IC and get it welded up.
I would suspect that the new plenum should run about $250 - $350 with the provisions required to mount the IAT and MAP sensors. Add in the other minor items and it should come in around $1100 which is not too bad.
I know the list of people who want this are Me, Brad, Smitty and Eric so far. Do ya'll want to get everything made locally and purchase everything directly?? Or are ya'll wanting me to organize this as a single purchase??

Steve,
This IC setup will require maching of the upper plenum? or no? I want to add an IC to my SC and would prefer that you prepare everything as ModAddict said. I am just making sure that I could use this application with the direct port. Could we use this plenum still?
Thanks, Logan

Unfortunately no, that whole upper plenum is being replaced. The only thing remaining stock is the lower runners/injector base which is untouched in your direct port application. So none of that beautiful pipe bending could be used.
Everything outlined in Red below will be replaced:

ya know... we broke up the tasks. So I agree with Brad.I was under the impression that Steve was working on the Intake manifold & IC, Eric was working on the chip, I was working on the exhaust and Brad is working on 7.5 boost pulley & IC.
You know I am down for whatever... you guys get the first Simulators, flanges and dumps made.... around $220 total for 10-15 Hp...<--- but I am just guessing on that #.. it might be more or less... I am still awaiting parts before my dyno date is set...

Since we have already gone up a size on the alternator pulley, going even larger would require a new belt which might prove difficult. It also might cause tensioning issues. However, by going smaller on the SC pulley would put us back to almost the base configuration and using the standard belt.
Just a thought...
BTW, I'm going to start a separate IC thread as this one has gotten long and diverse.

I also have been in touch with another pulley supplier that has a quick change pulley kit for eaton blowers that looks good, especially after changing mine four times. I will pursue that direction also. I'm pretty sure the jack-shaft assembly is a standard piece from Eaton, so that end should be easy also. We just need to get him one of ours to take a quick look at it. http://www.southfloridapulleyhq.com/...ucts_frame.htm (click on "pulley Systems", then the top item to see the interchangable kit). I think this company will be a better choice for us than Payn Tech, for our pulley needs, wether it be the stepper or the blower pullies.

I was thinking I might start with pictures so they can see the Jack shaft and pulley set-up. I'm hoping it's a standard Eaton set-up and all he might need is the pulley diameter. The pics I will take and forward this weekend. If he needs the actual pulley,..... well,....we'll see.

Steve, there is an off the shelf, (special order), 3.4" blower pulley that should work with our set-up, but I'm thinking that size may take us straight to 9/10 psi with the 6# stepper and 7/8 psi with the stock stepper. It's used on some of the Grand Prix kits offered by http://www.southfloridapulleyhq.com/ . I think he will make any dia. we want.

As mentioned before... it is a TOO damn hot right now.... along with TOO many damn things going on ..... i.e HEAT, wheel hop, gauges, pulleys, chip, exhaust...... ahhh, my head is spinning..... the nearest damn track to me is an hour away... I wish I had an evening to piss away..... I am waiting till it cools off and I break out my REDNECK/Wrenching flannel shirt one night.
FYI boosted guys, the UPS man stopped by with the SIM parts yesterday... time to get crackin on my part...Smitty

Just pedal your 3.5L beast around the elderly and leave us boost guys alone.

Oh, I just found something interesting today when I go on it on an on-ramp today. With the higher boost pulley my fuel pressure jumps to over 100 PSI, max on the gauge, when I get on it. Today I noticed that it was dropping at the higher revs and the boost wasn't falling off.
So this says to me that the fuel pump can't supply enough flow. I'll try to attain another unit to test with just to see if my pump is having problems.
