ClaudeMachining Posted December 6, 2018 Report Share Posted December 6, 2018 If you dont raise the compression, you doenst need 100LL.100LL is safe to about 165lbs static comp, so i "guess" 22-23cc can get you there. What's the static compression with your 24cc?? About 140???Envoyé de mon SM-G965W en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...

Given my squish .050", I'll be okay but I think it would be safer to run smaller domes right?Sent from my SM-G960U using Tapatalk Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted December 7, 2018 Report Share Posted December 7, 2018 0.050 is on the safe side for sure.What is your static compression with 24cc???Envoyé de mon SM-G965W en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...
MrKayak350 Posted December 9, 2018 Author Report Share Posted December 9, 2018 I don't remember for certain. Somewhere in the range of 145-155Sent from my SM-G960U using Tapatalk Quote Link to comment Share on other sites More sharing options...
Keno Posted December 9, 2018 Report Share Posted December 9, 2018 I was running my 421 Serval on 21cc Domes, 0.055" squish, a 1:1 ratio of 91 and 100ll, and using curve 3 on a Dynatek, which is 15* at 10-12K rpm (similar to +6). Elevation 1500ft. Didn't have any deto. I forget what my static compression was, though. Currently running 91 octane on 24cc domes, 0.045" squish and 13* at 10-12K (similar to +4) I honestly haven't bothered checking comp on this setup. These setups used Shearer SBIF and PWK 35s. Hopefully this helps a little 1 Quote Link to comment Share on other sites More sharing options...
