Do you have any head work done?
Thats the next thing I'm doing is porting the exhaust and installing .005 bigger exhaust valves, with 90lb springs and deleting the balancer's. I just need a good cam or find the best numbers and have comp cams grind my cams to the demensions. After that who knows?
oohhyahh, whats your HP/TQ at the moment?

Reading and looking at the design its really looking promising, now just sitting here and thinking about how you cut and re welded got me thinking air to air inter cooler would be awesome but no real definite design for a manifold or anything but , i know I'm no engineer or anything but i copied that design a bit and painted an idea around it might be hard to explain but what about separating the 2 cambers creating kinda like a box on the outside and a out let on the top going down to a air to air inter cooler setup and coming around to the other side on the bottom same idea going back in here is my weird setup i redrew on paint.. Lol don't make fun just and idea your guys thought? this is a really bad paint job and it may be dumb but I'm just thinking, or maybe someone had a similar idea i dunno
doesnt look bad but is it necessary to have that pice on the front come off the intake manifold? you could just run the pipes off the stock im, one on top of your splitter out the front and on under it to return

You have to distribute the flow on the engine side properly, or you run the risk of leaning out one side of the motor. Then your back to square one... blowing one (or two) of the pistons.
As well... you can't simply just hook the blower up to a tube and hope that it's all good. You need a specially designed plenum to absorb the pulse shock off the blower. Other wise your constantly bouncing the flow between laminar and turbulent, and the cooling affect is crap.
There is a reason my manifold is taking so long to design.... there is an actual though process behind it.

No exactly that easy.

I know its not as simpile as connecting some piping to the blower and calling it good, my idea is similar to yours in fact as why redesign the entire then you would port it out, and extend onto the design, creating an addition to the plenum. I wish could find an auto cad of the original plenum design, I might be able to make more sense if i could scale it and draw an exact prototype of so sort and then re-post. take note I'm not at all do I think redesigning something is easy, just thought of this while reading your post. you could say you inspired this idea :P. Oh on another note seen your from stoon I'm down in the Jaw, there a good shop up there to get a tune//dyno? if so cost?

Yeah... I was from S'toon (moved a month ago to Maidstone, by lloyd).
Talk to Rippin07 in the S'toon chat thread. He works for GSS. They have a dyno there that is apparently pretty cheap. Both Rippin and Raptors do tuning in S'toon.
There is also Performance Plus. They're pretty good guys as well, although I think their rate is a bit higher, and they don't have an HPT guy there.
Honestly though... Russ K lives in Regina, and is one of the best tuners in western Canada. Shoot me a PM if you'd like his contact info.

No clue about a CAD file.
I had to model my own Solidworks file when I did the initial design for this new manifold.... but I never bothered to model the plenum. Just the flanges, so I could get the positions right.

It was amazing I will post all the data soon. A quick over view is this, It made an additional 31 hp and 22 ftlb of torque till 5000 rpm's then the belt slipped and from 5k on. I went down two 250hp and 190ftlb from 267/246 remember this was at 5k I still had 2k to go and the hp/tq curve was on a steep upslope! I will deffinently exceed 300hp once I get a manual tensioner. The most amazing thing of all was the AIT. On my previous dyno tune with the 2.7 and luminova's I made 236/224 with AIT 2 pegged at 6000 RPMs wich is about 240ish degrees with AIT 1 at 90. This pull the AIT one was about the same but AIT 2 was 140 degrees thats a hundred degrees less!!!!!!
I need to do more analysis but as of know it's deffently worth the money and effert! AIT wise, it basicly operates like a 3" pulley with dualpass and huge front mount. but with huge numbers. I'm just pissed the belt slipped, go figure!
I will be getting the first couple of cores soon so IM me if you want one. Also freakta will be getting the first one off air/air setup I have his intercooler already and the first core I get is his!
Thanks and I'll update as soon as I'm done reviewing the hpt data.
As you can see below the torque curve drops off at 5 grand thats when you could audiably hear it. I noticed cause it wasn't heat soaked it didn't hert the HP that much untill the belt let loose it was just slowly eating away at the torque! Well hear is a smoothed image more to come once Fred remails the data.
