I was reading an article about raising the compression ratio on a N/A 1600 CVH, and it said:

"Use 1300 Mahle pistons, which have a higher crown and therefore raise the compression ratio to 10.2:1 without head modifications".

This sounds good since standard compression is something like 9.5:1, is it true?
Anything else i should know about doing this?
Has anyone on here actually done this?



Cheers people

 

i heard of this one a while back.

 

Cool, cheers! Must be some truth in it then

I hear its common on 1600 crossflows, anyone had any experience with doing this to either the CVH or Crossflow?

Would I need to change the crank to 1300 too or not?

Thanks all

 

A mate of mine has done this e-mail him and ask freakpower300@yahoo.co.uk He did this to his 1600CVH years ago

 

Cheers Johnny

I'll get in touch and see what he says
