i ve seen setup like it on aircooled beetles...i dont have clue how they work tho lol

I have a mate that ran a draw through setup on a buggy with an aircooled beetle motor. It ran really well. He used an SU carby I think, the bike style ones with the slide throttle plate. He only had a small kkk turbo. It was easy enough to tune, he did have some serious icing up happening though especially when he hit the sand dunes. That thing would 3rd gear wheel-stand in the sand.

You obviously won't be able to intercool, my mate ended up running a water setup which worked off vacuum, the water was sucked in.

yea, no intercooler, which generally limits the kind of boost you can push, and thus limits end numbers.

You can run a standard carby which is good, you don't need to get a carb pressurized, which can be a bit expensive.

You can move the carb around too, to place it slightly better, ie not about the exhaust.

yeah, water injection is what i was thinking would be a good idea - it was all the rage back in the 30's and 40's... esp aircraft engines and superchargers.

A mate and his brother are into Sigma Turbos and one of theirs was a carby turbo I have another mate who used to have one also. They run alright from memory chew through fuel though.

blow through or draw through?

And do you know what boost they we're running?
