Billet Intake Manifold for the Tunnel Port Intake Adapter

I don't know how this could get any cooler. I can't wait to see how this all turns out. As for issues with a distributor and EFI I prefer something like this with either coil packs or coil on plug. http://www.pricemotorsport.com/html/body_camshaft_synchronizer.html

Those setups work but they don't take advantage of some of the benefits of a really good EFI system.  You need to have a multi-tooth wheel to really get those benefits, like the 36-1 toothed wheels that Ford uses.  But they are nice for switching to coil packs or coil on plug, because they drive the oil pump with no distributor...

how did you come up with the amount of volume you wanted in the plenum?

[jayb]

The plenum was driven more by hood clearance issues than ideal volume.  But as a general rule, you want about the same number of cubic inches in the plenum as the engine displacement, for max power production.  That changes somewhat as peak power RPM increases, favoring a bigger plenum, but for most of us running up to 7000 RPM or so, its pretty close...

Cool stuff Jay.  Yeah I have to admit that I cringed a bit when the picture of the Holley "upside down bread pan" first popped up on the screen.  That needs a lot of lipstick!  The rest of the stuff looks pretty slick 

For 3D printing ABS, I've seen that having a heated bed on the printer really helps with warpage.  I'm starting to get into that a bit myself, but starting with the easier PLA material.

[jayb]

My printer does have a heated bed, Bill, in fact it heats to 100C when printing ABS.  But when the print is 20" long or so, and several inches high, warpage is still a potential problem.  Some of the really top shelf 3D printers put the whole print in an oven basically, so that the entire print stays at a high temperature until it is finished.  That's probably the best way to 3D print large ABS parts...

I have to add some height to my tunnel ram plenum,, the new distributor is right at the bottom of the TB, so cant adjust timing where it is now.. I need to raise the top plenum 1-1/2 inches or so, but will have to figure what I have now and see what I really need I guess for it to work the best.

Looks absolutely fantastic, Jay!  I really needed (wanted) a fuel injection intake that could be utilized with a belt driven supercharger (have a Vortech V4 on hand) or a pair of turbos. Yet no one makes an adapter plate for the FE. Aesthetics, flexibility, functionality, and possible expansion capability on the initial concept is what got me interested in this project. Been admiring Jay's work for a while and with so few TP options available, Jay was headed in the right direction with this market endeavor. Looking forward to the end result.

As for the EFI, haltec has a "drive by wire" controller that would allow you to use an LS throttle body.
I'm sure there are others that do the same, but being able to use a LS throttle body in that would be neat.

[jayb]

I think most EFI systems would allow the use of an LS throttle body.  It would use a GM throttle position sensor, which is easily integrated into most EFI systems; they are simple, three wire devices.

Cool project....

Hey Jay, did you study my adapter pictures? I see some resemblance to my design! I like your idea for the runners, it would have saved me some time in the welding on the finished part. I don`t see a way to use the MSD or HEI with out using an offset drive, but some thing may pop up.  Garry

What I meant was the "drive by wire" throttle body, the kind that don't have a throttle cable or linkage, its electronically controlled. Would fit that upper obviously, and has some really neat benifits compaired to a mechanically actuated throttle.

Yea, outside of some old Nissan units, think most throttle position sensors work the same...

I see, thanks for the clarification - Jay

I think my runners are longer than yours Garry, but otherwise they are rather similar.  Of course, my design has been on the drawing board longer than you've had your intake adapter
