You are correct, I tried to monitor the values this morning and they indeed change when you cross the 3k rpm threshold. I think it was 21.3 below 3k and 22.7 over.

Any updates on using the E-85 blend with your 91 or 93 octane. It's been a few months now and I didn't want this to die out. My personal opinion is that this is an awesome time to be an F owner. It's nice to be able to get a little more performance whether you are FBO or stock.

Spoke to a fellow ISF owner 6 months back when I was home from school and asked him if he ever blends. He said he used to all the time but noticed after awhile his car was consistently losing to cars he was beating before (yes the cars still had the same mods). I think he said he had to replace fuel injectors and/or spark plugs or something because of it, but I figured maybe it was because his car was an 08 with like 150k+ miles on it. He said once he went back to 91 all that went away. I took all he said with a grain of salt and figured he probably blended too high all the time since that's the only time I heard bad results about it. I blend all the time in AZ and my car seems to love it, someone just needs to do before/after races with someone to see just how much of a difference it makes.

fbo isf has been blending for a long time and no lost of power, we also have someone with full e85 and pulling strong without issues. we are also at a higher altitude with no issues blending

Just started blending myself, my KCLV numbers have improved. I'll probably keep blending.

Is there any dyno runs with e85 blend to compare it .Would have to be same car same day to get a fare comparison. Would be good to see the difference on paper.

For some reason, neutral is position 8 and 8th is position 9. Reverse is position 14...no idea why.

Default Fuel additive

Would Lucus upper cylinder lube be safe and still effective with the 30/70 blend ? If this has already been covered, apologies. But this is a long *** thread lol.

Found this video..looks to have higher torque numbers than other FBO F's, but puts down around the same WHP.

^^^^^exactly correct better TQ and throttle response and higher octane rating with a cooler burn are the benefits of blending E85!


As a matter of fact I have been running E70 in my minivan with excellent results
