Curbs go brrrppp
So i thought about putting this into the tech section for s197 since i have a 2013 3.7L. I thought its more generic and may get more attention here.
Personally, i feel like too many people get 93 octane for track and never test this. Ive used 87 to 93. I have the tuner. On track, the on board timer, wherever, I've never seen an improvement in economy or performance going to 93.
I've even tuned the car for 93 and it never mattered. I cant say ive run tracks on both fuels in a way that matters and came to any conclusive result. The car seems to happily burn anything i give it.
I have put no ethanol in it just fir fun since pure gas should have more energy vs the resistance to detonation that octane offers.
On the street, ive run e15 and no notable difference in power or economy.
Ive read reports tested in various ways, the closest thing ive ever seen was an e30 test where the car did worse as it heated up on high octanes.
So my question after all that... has anyone seen any data in a track environment, specific to our cars or otherwise, indicates that higher octane is better? Not subjective feel, i mean data showing higher straightaway speeds, etc. Obviously I'd love specific to my 3.7 but i know thats a stretcj to ask.
