ATI Harmonic Crank Balancer - Want to safely rev your S52 to 8k?

[pizzaman09]

This is all very interesting. I knew the crank shaft had issues at 7200ish rpm, I didn't know that it could be solved with a new harmonic balancer.
I have a custom engine head on and M52B28, that really doesn't have an rpm limit. I'm tempted to get one of these dampers and try it out.

Anyone selling one of these that's not for the VAC highway robbery price, let me know.

I want one so my A/C belt stops coming off.

His balancer doesn't have an A/C pulley.

Good catch! I just delete the AC then! Lol.

Keep the A/C unless it's a dedicated track car.

If you contact him I'm sure they could add on an A/C pulley. The harmonics change, but it's 100% possible.

P.S. Your build log doesn't load
R.I.P M3Forum. You should recreate it on Bimmerforums.

I messaged that dude. Depending on price I will probably just lower my redline and wait for my S54 that I'm building. Build log should just be my @nholmes74 on IG. I'm done with forums. After M3Forum torpedoed three years of my journal, I'm done.

Don’t be a quitter. IG is lame

Guess I'll just have to try a few other things and see if it works. S54 swap is going in this time next year so maybe I'll just lower the redline and be done with it. Tired of dealing with this.
