Re: [DML] PRV engine output

[Martin Gutkowski <webmaster@xxxx>]

The big problem with all below the "light cost effective" suggestions 
relate to the odd-firing of the DeLorean PRV. My engine guy has said 
that you can only really go higher than 230hp reliably on a 2.85l 
odd-fire PRV by upping the idlespeed and using daft cams. For practical 
use, 220-230 is the maximum. A little more can be had with the 3l 
pistons, lightened to the same weight as 2.85. This is as high as you'll 
go with the engine *looking* stock.
