ProTouring schematic

[Drago]

Fellas, I already started a '66 Ford Fairlane ProTouring project, but now I´m intended to get some modifications on my project.

But first, a little help from the community:

Is this power schema a little unusual??? I mean... could it be possible? (technically speaking)

Ford 427 with double side draft Weber carburetors

PLUS

Twin Turbo

???????

Too much? Too crazy?

Tks.

Yes it is technically possible. But why? Search Rick Dobbertin's J-2000. There are several cars that have multiple carbs, and turbos, and superchargers, and nitrous all on the same engine. Once again why? This complexity is only to prove it can be done and the shock factor in seeing it all in one place. It will not make more power than say a maxed out single tubo fuel injected engine of the same size.

In fact a properly fuel injected engine will always make more power than a carbed one. If you are trying to make your's look cool, it is very hard with turbos and Webbers. The turbos have to either blow through the carbs, which means the carbs will be in a pressurized box and can't be seen well, or they will have to draw through the carbs, which will eliminate the cool looking traditional style intake manifolds.

But yes, it can be done.

I think the side drafts would take away from the protouring look. I think your turbo setup blowing into a cool looking plenum would be the way to go. But, anything is possible.

Is it just me or would down draft webers be better suited for this? I mean if you have turbos blowing throught an intercooler then going into nice plenums over the webers, Kind of viper like, I think it would work fine. I think a cammer engine would be cool with that set up as well.

With due respect wisdonm, you CAN run a carb/blow-through set up without it being in a pressure box and have it still function properly. You will have what is called a 'hat' that seals down tightly to the inlet of the carb (a pressure bonnet/plenum if you will) in place of the air cleaner. Run solid floats and a rising-rate adjustable fuel pressure regulator on the liquid side to keep things in line and it will run smoothly, reliably, and make GOOD power.

One thing to think about is intercooling/blow-off valving. Run a single discharge pipe from the intercooler and place your blow-off valve there. After you have placed your BOV, tee the piping off to their respective bank of cylinders (being this is a model, making note of running a slightly lighter spring in the valve to aid blow-off is useless as you really can't model that!).

Hats are an option, but 8 hats and their plumbing would totally obscure the carbs and any shock value. With all that complexity, you have to ask why?

Check out my avatar...Rather than Webers...modern injection and nitrous can make awsum power and look killer.

You don't need 8 hats; you would run 2 plenums, one for each bank of carbs. You wouldn't have a plumbers nightmare if you did it this way. I have made a common plenum for my Individual Throttle Body set-up on a Volvo head converted 2.3L Ford. With the plenum securely fastened to the carbs, you only need one per bank, with the inlet from the intercooler centrally located along said plenum to balance incoming pressure across the 4 carb barrels fed by the plenum body.

This man has the right idea. Forget Webers combined with any type of forced induction. Webers run on NO MORE THAN 3 psi of fuel pressure and you can't blow through them. EFI allows proper fuel pressure for forced applications. Remember a simple looking BBC with dual quads can make 1200HP N/A and 1800 on spray. Sometimes wacky-looking combos make models look toy-like. And Drago-you have a beautiful little man there.

I will agree wholeheartedly with the Fuel-injected route. But since he asked if his idea would work with carbs, I gave him an example of how it would/how to build it. Now, there is a company out there that takes vintage carbs and converts them to EFI set-ups. this would be perfect in this application, as he would have the look of carbs with the function of EFI. Some routing of the fuel lines/throttle cables would give the fact away, but it would look killer AND work.

Or he could say screw it, go full Individual Throttle Body per cylinder with two plenum rails made to look like old air cleaners for the Webers and REALLY have something cool and functional.

That´s why I like this Forum so much!!!

Thank you guys... all inputs are great.

I guess I´ll go with injected with bi-turbo...

Thanks a lot fellas!
