Same as before, use what Ford uses. 10 or 10.5 if going FI for best longevity.So what’s your recommendation?
I tried it both ways, that is why I posted 2 screen shots.On the summit calculator, you use a negative number for the dome.
LOL another senior moment.You put 15 inch not 0.015 inch
Like I said I plan to run e85 most of the time just need 91 support for casual long drives if I ever travel.We have 93 and I can only get 24 degrees of advance before knock sets in. Probably only get 20 on 91. MBT table says 29 is best torque.
This is an 11 to 1 gen 2 with 1 heat range colder plugs.
For my car I do. If you are mostly using E85 I would not. I run mine pretty hard on gas and do what I can to prevent pre ignition and detonation.Do you recommend 1 heat range colder plugs?
Maybe a 180+, but I think I will wait till I am able to upgrade the cooling. I got the motor too hot last time, and don’t want to do that again.@tdstuart
Any more long 170+ mph runs planed for the replacement motor ?
Was that last 176 mph pull on gasoline or E85 ?
Any other engine assembler fretting over a couple 1/10’s of CR would cc the motor. You might have more fun cc’ing it than playing CR calculator shuffle board with a few obscure values.
Ya I ran e85 straight for a couple months or e54 mix. I used a full tank in one day of driving around town. My MPG is seriously impressive.I've got true E85 close to me, pump is labled E85 and tests at 85%. I ran it for a couple of months and switched back because I was at the pump every other day. It works well in my P/U which has a 36 gallon tank.
