Higher octane fuels allow you to safely run higher compression ratios. I think 9:1 is a little on the high side and would personally look at lowering this or adding water injection. WebNov 11, 2008 · it all depends on the build. compression relate to not just pistons, but stroke and cc of heads. if you'r motor is 11 to 1 total with stroke, cc in head, and pistons you will …
WebNov 19, 2006 · The reason you lower your compression ratio is because of the octane required to prevent detonation. If you tried to run a 10.5 to 1 motor on 20lbs of boost you'd have to run racing gas to prevent detonation. ... Try running 20lbs./10.5:1 Comp ratio and pump 91 octane.

WebFeb 14, 2024 · The maximum Static compression that can be run still has to be kept in mind. One cannot run the Dcr up to 9.3, with a big cam that requires a 12.0 Scr to get the 9.3 with. No! the static has been well established for iron for years,to be: safe at 10, maybe safe at 10.5 borderline unsafe at 11, probably will shatter stuff at 11.5.

Water temp was always 120-130 though. Oil temp was 190-200 when running fairly hard. I wouldn't do anything over 11:1 on pump gas with aluminum heads. 10.1 with iron heads and nothing more than 36º of timing. einstein try not to become a man of successWebApr 16, 2011 · For example a camshaft of 280 deg and a 106 deg intake centre line would give an IVC of 66 deg ABDC. The effective compression stroke for a 347 becomes then: .5x3.40x (1+cos (66))=2.39". Calculate the cylinder displacement with this stroke and you can calculate the effective compression ratio.

The DCR is what the air fuel mixture actually “sees” and is what “counts”, not the static CR. Because DCR is dependent upon IVC, cam specs have as much effect on DCR as does the mechanical specifications of the motor. einstein toys for 1 year old
