Just a thought, Could you fit a plenum chamber after the butterfly choke, on a turbo engine ??

dont think so...... why would you want to?

And on the 7th day........... God created turbochargers!

Just a thought re my three cylinder, it has a water 'cooled' inlet manifold , so is a little trick to mod

the water pipes to the inlet manifold would not be there to "cool" the intake but to actually heat it up when the car is cold :)

Thats why 'cooled' is in inverted comma's, as during winter it will heat, during summer it keep it stable !

EFI turbo engines get best results from having a 'plenum' style inlet manifold. Just do a search for piccies of the YBB / YBD engines used in the sierra cosworths. These had a large volume plenum that was (at a guess) 3 litres in volume. Corky Bell states that the optimum is 1.7 times engine capacity.

So, yes. Cut and shut your manifold.
btw check out http://www.themininut.com and follow the links to his 'plenum fabrication' section. This is the right way to go about it...

Cheers dave, thanks for that
