Turbo on a Carby?

[2xclutchin]

So is there a way to put a turbo on a 89' carb'd B3? I don't exactly plan on doing this, just a question that popped into my head. I'm sure simple folk have asked before, but I didn't get many results after searching.

So this would be where one would reply with "If you have to ask you probably won't do it." I won't, but I sure wanna know! haha

Don't make fun of me to much!! :p

Thanks, Mike

Carb turbo setups are not the most uncommon thing in the world, but on a festy its way easier just to do a 'normal' efi turbo swap.

It would take a ton of fabbing to get a carb turbo b3 to work. 0% chance of it working with a festy carb setup and a weber aint gonna cut it either.

I get.curious sometimes about weird stuff to. To answer your question, ANYTHING can be turbo'd but a feedback carb would most likely not work. However I'm sure there's a weber out there that can.be converted to blowthrough but after all that trouble an xr2 swap is much more " beginner friendly" for lack of better words. Because of this site that is.


fF.com FTW again!!

ok brad, not callin you out, BUT.... the factory carb CAN work (as well as a weber). what you'd need to do is pressurize the carb (sealed box) and have a riasing rate fuel regulator that's tuned to a 2:1 (or so) increase. you'll also need to re-jet the carb, but very doable.

Propane carbies and turbos !!!

Plus one above, keeping track of where pressure differences are and where
they can go, this was more common years ago before injection was common
and feasible.

Quite a few VW rails with turbos on webers or dellortos were made..used
to be common on the dunes.

Didn't someone on here already do it. I think it was a primer black car. It was a very clean setup iirc.

But, for the effort, is it worth it? Is it gonna make any more power than a b6 swap? And...how reliable is it gonna be?

This is quite awsome to read. Now I just wish I understood more about the pressures involved.

The internet is my friend though, and after work I think I'm going to begin attempting to learn.

Thanks guys, Mike

That depends on a lot of crazy stuff...^^^wupps, Bhazard is who I answered!!

You could blow through on a weber 3236. I'm considering doing it until I can afford a megasquirt. I already have a sealed box for the top of the carb with a 2.5" inlet on it.

So I'm assuming the sealed box takes place of the normal air cleaner, in order to transfer the boost into the engine. What exatly does it mean to "blow through" unless it's just as simple that it is able to be turbo'd.

Sorry for these simplton questions, but I always have been the type that turbo's are for diesels and superchargers are for gas engines, and I don't know much about that either :p.

Thanks again, Mike

Wait a min, supercharged Festy!! :p hahaha Could I use the super charger off of my 2-71 Detroit Deisel, or would that be a bit much? :p I keed.

there's blow through (turbo before carb) and draw through (turbo AFTER carb, like in the Corvair Spyders). rollertoaser has a style you'd typicaly find with a centrifuge supercharger. what i'm about is a box that encloses the entire carb air tight. this makes things a little easier for tuning as the bowl sees the pressure and can compensate more easily than a tophat setup.

[2xclutchin]

So in a draw through the carb would just have twice as much air coming through it, meaning more fuel also? So wouldn't that type of set-up be "easier" in retrospect to the other way?

I honestly am kinda talking out my hind-quarters since I have no idea.

Thanks, Mike

Also Thanks for that link Fred!!!

draw through is easiest, EXCEPT for the mounting... and that's the important part. there's an article in Corsa Communique about the corvair spyder turbo system and the jist is this: 10psi was safe for premium fuel of the day and they had to choak the exhaust system to limit the output from 220lbft to ~170 to keep from lunching the trans. good info really, but i have no way of posting it on here.
