Hey I just built my motor and I am running about 11.5:1 compression and I was wondering if 91 is ok or if I would screw anything up if I ran 110 octane or 100, tell me what you think.
you’re probably at about the highest safe compression for 91 octane…
octane
to be on the safe side, i’d run 94… i use to own a civic with a b18c5 build up and I only used 94 in it with the occasional octane boost when i felt like racing.
We don’t have 94 by me. Do it is safe to run 110?
not if u wish to keep your engine, i had a buddy of mine do it in his crapstang and he no longer is on that engine, just my $.02
