There are so many automobile educated people on this board I hope this will actually turn into a on topic post.There are B.M.W.s running 12:1 compression.I've seen street tuned cars in mags running 12:1 with alky injection.What has to be done in order to do this?Do you need more fuel? Do you need a way to retard the timing?Will the car respond better to basic mods with higher compression?Would the difference be worth the amount of time and work?The 3.0 300h.p. B.M.W. is proof it can be done and I know that car was designed from the ground up to make that kind of power. I don't think this is possible on our NA cars and still be streetable but 260-275 would be nice.Is there that much untapped power to be found without nos or a turbo?What about making it through daily driving?I built a 55 h.p. V.W. engine to just over 100h.p.all motor. That is considered Micky mouse compared to some of the street V.W.s built to over 200h.p. I know the aircooled aftermarket is huge but shouldn't the same principles apply?
