carburettor draw through turbocharging

[Guy_H]

I built a couple many years ago on aircooled motors - there are a couple of good books available on Amazon on this subject that are well worth reading before you start spending cash on hardware!

thanks guys - another quality thread from the tuning and perf section

This is the book you need - it seems long out of print & I can not find my copy:

Looks like you will have to pick it up from ebay!

Dellorto's or Webers work pretty well for draw through, only Dellorto (modified & sealed) for blow through - Weber is too hard to seal.

Never tried it with SU's

I reckon you should give it a go. It will be good to see a turbo set-up that actually matches the period of the car. A retro turbo setup and theres no reason why it won't be as fast as hell too.

And just think you'll have the carby guys and the turbo guys on your side.

i agree - i like the idea of something period.

***quietly mentions...***...its not going to be for street use, i'm thinking hillclimb/track.

If you go forced induction in most forms of motorsport, you'll be penalised for it I believe. your times will be X by 1.3 or 1.5 or whatever the ratio is.

I believe that's how it goes though.

Webers and Delortos work on pressure, whereas an SU works on vacuum, so i'm not sure whether an SU would work blow thru.. However don't quote me on that.

I like the idea of draw thru carbie setups, however i'd do it with a supercharger. .

Yes, you can't run as mouch boost, but i'm assuming you're doing this to a Mk1, in which case, 6 or 8 PSI would be plenty anyway. Any more boost would yield pointless unusable horsepower, unless you just want to be able to quote the peak HP figures, and i KNOW you aren't about that.

My uncle had a draw thru supercharger setup on a toyota 1.3l in a nota back in the late 80s. Went pretty hard apparently. He used a 2 inch SU. Seems to be that SU's must be easier to tune for this purpose. If you like, i'll get some more info off him about it.

Actually your engine capacity is multiplied by 1.7 so your 1800 golf ends up in a 3.0L class racing commodores.
