As you all know, we have been planning to develop some sort of EFI kit for the aluminum head for quite some time, so I finally decided to get the ball rolling. Since we've worked with Extrudabody in the past, we decided to hire their services and see what we could come up with. To date they have spent over 100 hours designing and modifing the various parts to our specifications. Needless to say, I'm very pleased with the results.
By producing a billet (or cast) manifold, a handful of adaptors, and a cast plenum chamber, we will be able to offer a wide variety of induction options. Naturally aspirated or boosted, carbs or injection, we've got it covered.
The design of the intake allows us to use Extrudabody ITB's, any Weber style throttle body, or triple Side Draft Webers (DCOE). We also designed an adaptor plate so that the plenum chamber can be bolted directly to the intake, which allows us to use a single throttle body, mounted to the plenum inlet with a flange adaptor (such as a 5.0 TB).
However with such a wide variety, we'd like to know which induction system you would be most likely to purchase (or upgrade to)? Our existing 2V/4V intake, or one of the new kits listed below. See Poll above....
1) Naturally aspirated - Weber Side Sraft Carbs
2) Naturally aspirated - Single TB
3) Naturally aspirated - Multiple ITB's
4) Naturally aspirated - Multiple Weber style TB's
5) Boosted (turbo or S/C) - Single TB
6) Boosted (turbo or S/C) - Multiple ITB's
7) Boosted (turbo or S/C) - Multiple Weber style TB's
Just to give you an idea of where were headed, here's a few of the CAD renderings and a simulated flow test. Please don't ask for any specifications or flow numbers, as we won't release them until we actually produce the parts and test them on a flow bench and dyno. We don't have any pricing established either, so please don't ask....
Cast Alloy Plenum Chamber mounted directly to the intake. We still need to design an adaptor plate (or flange) to fit on the inlet, so a single throttle body can be mounted. Note: the plenum can be rotated, with the inlet mounted fore or aft.
Standard intake with ITB's and air horns.
