Engine with an 11:1 CR, can it be turbo'd?

Postby fha772 » Sun Aug 05, 2012 10:01 am

Hi all,

I was just doing some random googling last night, and I decided to see what the compression ratio of my Audi's W12 engine was, compared to the Bentley version.
The Bentley, which is turbo'd, is 9.0:1, the Audi version is 11:1 (the VW version is in between at 10:1).
I've heard of people supercharging and turbocharging the Audi engine, which got me wondering.

Can I fit a low pressure turbo system to this engine, without having to alter the compression ratio?
Or, would I be asking for trouble?

This is just a hyperthetical question, as SWMBO has banned me from modding the Audi until we've finished paying for it!! :lol:

Cheers Frank. :thumbup:

This! You know it makes sense financially, at the least it means it'll be paid for sooner :D

Also bear in mind thats the static compression not what its like dynamically. It could be changed by long value openings but I suppose thats unlikely on a W12 engine in a limo :think:

Wouldn't Nitrous Oxide be safer and work even better with LPG? ;)
