POLL: How high have you revved

[Boyracer]

Thank you guys, it seems that atleast 7200 is well safe with stock springs

Model (E30)
Engine age (8,000 miles)
How high have you revved your engine without damage (7800 rpm)

For the M42, raising the rev limit isn't about HP (I think we start to taper off around 6800 or so) but about eliminating the shift from second to third

...that's why stock 318iS have such a pokey 0-60 time

no dyno chart yet... I know I know I'm a hopeless procrastinator...

lol. yes you are i'd love to see what yours puts out, you run quite wild cams don't you?
8k miles, I've now put 25k on mine, and it wasn't built that much before yours, only 6 mths or so iirc!

The other factor here in working out max rpm is the accuracy of the clocks. I've noticed that mine are really not all that accurate at all! I always use megasquirt to calculate my rpm. With the M3 clocks and IS coding plug the rpm is ridiculously out too, have not tried m3 clocks and m3 coding plug on the IS however.

I can come up with a fairly close dyno chart...
I will see what I can do tonight, not 100% accurate, but should be within a few %.

Full blown Metric Mechanic 2.1 stroker motor.
He is pushing over 200hp and redlines at 7500 or 8000.

The torque rolls on just above idle and it never stops pulling.
Basically it is the engine BMW should have put in our cars, but didn't because it would have embarrassed all other e30's including the M3.

that's what i want then!
