Thread: Domed pistons and quench?

Tweet

everyone does try to go for as much compression as their fuel will allow. this includes the nitrous guys. nitrous does really care about compression like forced induction does. the more compression the more power for n/a and nitrous motors at least. when you get into forced induction, then its a bit different, instead of trying to squeeze the piss out of the air you alreay have in the cylinder, you try actually get more air in there and out. you could run a blower on a higher compression, but then you could only run a little psi. if you drop the compresion ratio down, then you can safely run higher psi, which equalls more air, which is more power.

to decide on which compression ratio to run depends one 2 things more or less. what type of power adder are you using, if any... and what octane of fuel you will be running.
