Stock is 7599rpm.
I've always used 7780rpm, assuming that less than a 200rpm bump is safe on an unopened 4B11. I don't ever want to hit the rev limiter, as lots of people have experienced plug breakage with that. Maybe raise it closer to 8000 to prevent hitting it, never rev past ~7800, and don't let others drive your car? Thoughts? Thanks.

 

Well my rev limiter is set at 8100 I believe but I rarely use it except at the drag strip. I think there's a lot of factors that come into play choosing a rev limit

 

I did 8k on mine all the time but I had upgraded springs and in there. I woud not rev past 7800 on the stock springs.

 

Thanks dudes! I concur black E.

 

I always rev the limiter up to 9rpm on the mr.its fine

 

^^lolz!
