Seems like this is taking forever, but they finally got the programming done for the new intakes. Hopefully I'll have some proto types in a couple more weeks, but who knows. I've learned that whatever I'm quoted for a timeline, needs to be doubled at best, and tripled in most cases. It frustrating, but not much I can do about it, as it seems to be a common standard in the industry. Especially when you use companies that are well known, or the best at what they do. They usually have more work than they can handle, so you just have to get in line and wait your turn.
Here's a cad pic of the new intake. They put ribs on the runners to give it a nostalgic look, but I don't know why they didn't put them on the 3rd and 4th runners? I made this a poll for you guys to vote on, as I'm not sure if I like them or not? The poll ends in five days, as I need to let them know ASAP so we don't hold up the intakes.
The carb opening is square so the carb adaptor can be turned 90 or 180 degrees. Example, if you’re running a 2V carb, you can mount it parallel to the crank, or perpendicular, depending on the application. I also asked them to move the injector pads closer to the flange for improved clearance.
Having the ability to turn the adaptor also allows the option of running a twin side draft Weber setup. On a V8 application, the carbs go out over the valve covers, but this won't work for an inline application due to shock tower clearance. However if the adaptor was turned 90 degrees, the carbs (or TBI's) would face fore and aft, making a killer setup with outstanding eye appeal (WOW factor).
We will be offering adaptors for 2V and 4V carbs, and some sort of throttle body. The adaptors will be made from billet, or possibly some sort of plastic or phenolic material. I'll be getting quotes on them later this week. We left the floor flat, so we can do some testing on a flow bench and/or dyno, using ribbed bases (turtles). We found a shop that will do the testing and design custom turtles for us. Once we find out what works best, they can be added to the pattern for future castings if we chose. But I think I prefer inserts as we can use different turtles depending on the carb type and orientation. Here's a pic of a V8 turtle, just for reference.

We are also looking at modified carb adaptors with plenum tubes. For example, a 4V carb adaptor would have four individual tubes that extend into the plenum. The tubes are CNC machined on the adaptor base, each matching one of the throttle bores. The idea behind them is to isolate the carb from plenum turbulence, which inturn offers mid-range boost and is particularly effective at counteracting fuel standoff. The results include better throttle response, better fuel atomization, maintained intake velocity, and increases in the upper low-end, and midrange horsepower and torque.
I'm might run the twin TBI's on the 250ci I'm building for my 66 coupe. I was going to go with triple TBI's, but considering I already have triples on the 69, this would be something different, and a bit cheaper. Setting up the linkage and plumbing should be pretty easy. I'd really like to take it to Portland, but seriously doubt I can have it ready by mid August. The next race is in Sept, so I guess I'll shoot for that one. Even then, I probably won't have much time to test and tune, and work out the bugs
