I had a lot of requests to post more pics of the sheet metal intake manifold, but I lost the pics. Recently was able to find the old memory card, so here it is. This setup uses a 90mm throttle body. All the port entrances are fully venturied for optimal flow. We manufacture and sell this part for anyone interested. Its a half-way step between the stock intake and Gordons fully custom tapered runner design.
Price is $1100.00

Its cool guys 
I am never one to miss a chance to learn more information. I did go back to the dyno today, and got to stretch the FD's legs a little. Did all types of video, and
tested 4 setups individually. Here is a overview, going off memory. Dyno charts and vids coming next!
-First I streamlined the semi p-port manifold some, just making the best of what was there. Did some pulls, and it did indeed help and made 434rwhp. Biggest surprise is 250 rwtq! excellent.
-Next I swapped in race plugs, due to so many members telling me that 10hp or more can be gained. I was a doubting tomas, but bought some anyway to test back to back. Result? 436rwhp. 2 horsepower for $190??? Yeah looks like this goes into the "busted" category.
-Then we swapped just upper intake manifolds, and ran the stock intake with semi p-ports. Shocking result #1 of the day, it make 420rwhp. Looks like semi p-ports are totally amazing in flow.
-Then I removed the gasket from the lower intake, and swapped in a stock one without semi p-port holes. This blocks off the semi p-ports at the flange. Then did some STREETPORT only pulls.
- Shocking result #2 of the day, the stock intake/streetport made 350rwhp!! Amazing!!!
Last time I tested the stock intake the electromotive software had a glitch which was not sparking leading #3. So Leading ignition missing on one rotor makes for a 28rwhp loss. In case anyone wondered lol
- Lastly we then swapped on the sheet metal intake/ streetport only. Kinda disappointing result, hit 355rwhp. It did lean out a bunch, and didnt have time to re-tune. I think it would have made 360-365. Only a 10-15 hp gain. But not bad!
