Unles your going to up your cr drastically don't bother. Also your going to have to retune your af as well as your entire wot timing tables to take advantage. The only way this is going to work in your favor is if your going to be atleast 13:1 cr.

When I upped my cr I tuned with pump gas, then mixed some race fuel to get roughly 100oct, then went back and re mapped the afr then timing maps. By the time we were done we ended up making the same amt of power as we already had with pump, and picked up a few ftlbs of peak tq. My cr is only in the mid 12s. So like I said if your going to run a high cr sweet, but otherwise it will probably be a waste..

This discussion is so cool, i never knew they were 15:1 to VEs about.

wat is the Highest CR that can be ran on a daily driver DE with 89 at the pump.

Jun, do you do anything other than tuning to accomodat the high a CR. like machine/headwork?

do yall think a 92mm bore and 11.5:1 CR is safe on for a daily with 89 at the pumps?

as expected, very little gains 199.97whp & 157wtq timing was advanced 3 degrees. But in the all motor class every little ponny counts Mix was 1/4 tank to a gallon of q16, and no exhaust

Yeah I recently tested with a bit higher oct. And the results were very little, something is something, including in the allmotor game.

Yeah looks like simmialr results to what I've seen. The thing that was surprising is that mine was 105oct after mixing and this was with sr16 pistons and only gained a few whp aswell.
