Rev Limit- How high can you go?
I have been pondering rev limits for my squirted N/A 1.6. AFAIK, the stock limit is 7,300 rpm.
Im thinking around 7,800 rpm. My car is tracked and autocrossed EXTENSIVELY in CSP with 13" Wheels. This translates into a bunch of time spent on or near the limiter for autox.

Up to 7400 since you autocross and track the car. For street use, where you don't hit the limiter so often, 7600. There is valve float above 7800, so there is absolutely no point going over 7800 on the stock valvetrain. Additionally, the stock pulley damper cannot damp the crankshaft's vibrations at that rpm zone (7600+), so you might have shifting problems (especially 2nd to 3rd) and if you insist on revving that high, you can shutter the oil pump's gears. Above 8000rpm you will destroy your rods. The B6 and the BP are boost friendly, not rev friendly (unfortunately).

My '04 MX5 SE (aka Mazdaspeed Miata) now spends a lot of time on the track, I've been killing brakes and tyres, so I'm going to go with the 201rwhp map instead of the 233rwhp one and aim to become a better cornerer. The ECU presently stops the action at 6500rpm, which seemed a good thing with the high power map, but was a bit intrusive in several places on the tracks I drive at. So when I finally work out how to play around with the Haltech, can I go with a higher rev limit with less boost?
