2.0 60ft's were in the 1.7-1.8 range. The 2.3 were 1.5-1.6 range.
Daily driven, 2.3 rules. A daily driver in the 11's is great.
All this was done on pump gas with Alky injection. No race gas. So it was tuned to run 11's all the time. As soon as I get my current project running, I will be swithcing to another Jerry 2.3.
pump gas + alky injection = race gas
Depending on how much you spray and with the effects it has on the octane and the cooling temps, people who say they run 10s/11s on pump gas then I see an alky injection on their setup are just in denial. 10s on pump gas means just pump gas, nothing else.
