Brian P Posted July 12, 2003 Report Share Posted July 12, 2003 no advantages only disadvantages....the 2.8 already has low compression Quote Link to comment Share on other sites More sharing options...
god910 Posted July 12, 2003 Report Share Posted July 12, 2003 Unless you go with insane boost, no reason to decrease C/R. I even think that a 2.8 (IF I am not mistaken) is low enough to moderately boost in stock form. Not that the rest of the engine would stay together, but that's something left for others to discuss.

dbtk2 Posted July 12, 2003 Report Share Posted July 12, 2003 Lowering the compression ratio is only good for running boost. If you have a lower compression ratio, then you can run more boost without knock. If you have really high compression ratio then you could lower it so you can run your car on regular gas, but it is very rare occasions where someone wants to lower compression on a N/A engine.

Robby1870 Posted July 12, 2003 Report Share Posted July 12, 2003 New pistons would be the way to do it. But, I do think it would be cool to build an n/a 3.1L with like 12:1 CR. I just think it would really neat. Robby Quote Link to comment Share on other sites More sharing options...
