Probably won't be 16:1 because I don't want to be replacing starters after every time I start the thing! LOL But between 12.75:1 to 14.5:1 isn't out of the question, just have to see what I can get out of flat tops and milled heads. This all depends on if in the fuel to run this thing is somewhat economical and easily available? Should make tons of torque, especially with an extra at least 20 more cubes, or at least 65 more if I use a sbb 300 with a stroked sbb 350 crank! I don't want to bore anyone with those details though, not yet anyway. Derek Thanks for sharing all the airplane info John, very interesting stuff for sure! I wish that high of octane was available to the public at a reasonable cost now! The EPA Gestapo killed all that kind of fun a long time ago unfortunately! But it did get the lead out of the air leaded fuel put there that we breath so not all that bad I guess. Boy does that lead smell good when you burn it though! Derek
Just put an ignition cut-out switch on it. We do that on our 500+ cube engines all the time. My street 552" has 13.5:1. I turn the ignition off, start cranking, then flick the switch and it lights right off. Starter has no idea it just lit that big pig up.....
For you John .. I knew I should have drove the Sporty instead of the truck today Jim - Reno IS on the short bucket list
If it matters to you, the product in question uses MMT. https://en.wikipedia.org/wiki/Antiknock_agent
Yes just like we did Xylene, but we discovered that Toulene has impurities that Xylene doesn't have that's why Xylene was a better choice in many opinions.
The classic Beech 18 Alan. At one time it held the record for the longest production run of any civilian aircraft.
