what octane to run on a superjet with bpipe?

[Gainera2582]

2001 roundnose with bpipe mod chamber stock cdi, 75, 135 jetting

I realize the stock requirement is 87 octane for the superjet, but do I need to move to either 89 or 93 with the bpipe on?


Thanks,



Aaron

All he has is a pipe. If you haven't upped your compression or advanced your timing (or have an Enhancer) I wouldn't bother.

Paul at Magoos suggested I use higher octane on my SJ and I only have a b-pipe and enhancer .
It keeps the motor a little cooler and could prevent burning a piston on any WOT runs .

It's about $.50 cents extra per gas can and is worth it IMO just to be sure
