Reply to "IR - Classic weber IDA or IDA TBI EFI?"

There are issues with both the systems you ask about.

I've been playing with the 48ida Webers on the 351c since 1980. My opinion is that they are never perfect, just some times more then acceptable. They will never be what you expect them to be on the street. On the track, that's a different story. Not much can stay with them from 100mph and up.

Under that, they always will have some type of stupid BS issues. For one thing, besides the transition flat spot, besides the cylinder oiling wash down, besides the twisting up of the linkage at WOT and then not wanting to idle, besides the black gunk that will coat your exhaust, besides the slime over the back of the car, besides fouling the plugs to the point you can't clean them up with a full throttle blast...they will glue the plugs to the heads to the point you almost can't get them out without pulling the engine.

Oh...and you give away 80 - 100 hp with them BECAUSE you need to use a cam with severely limited overlap (28 degrees) to avoid the blow back through the carbs. But other then all of the above, they are fantastic! LOL!

Now, on the "Classic Fuel Injection" Weber carb look alikes, yep, they look great. Now here's the BUT, and it's a BIG ONE. The company that makes them can't assemble them to the quality standards necessary for them to run as advertised. Specifically, they can't assemble the throttle plates accurately enough for the idle air bleed screws to work.

You need to adjust your ignition advance down to idle the car down. Is that a big enough one for you? In addition, the casting quality of the housings themselves is so poor, they have to be SHOT PEENED to make them look right. So don't look really close at the details.

The company has been sold and resold about three times within the last 18 months as far as I can figure to avoid bankruptcy. What they call themselves at the moment...don't know for sure.

What are you going to do if you need parts for them and the company is gone?

You need to use the Haltech Platinum 1000 sport, or they won't work at part throttle at all either.

Also, the fuel injectors used are...geese, can't remember the part numbers...but they are supplied by Ford Racing and are a unique injector in order to fit within the Weber look alike housings. Read that as limited variety and expensive. No $300 per set here.

You are better off waiting for someone to make a crossram FI system specifically for th Cleveland. One that fits under the screen. Just my 2 cents.
