New friction surface? Were you planning on having it resurfaced?

the flywheel is an aasco LWFW. the friction surface is a replacable steel insert.

i feel a tiny bit of vibration from 4k to redline that i think is coming from the flywheel. it's very subtle, but i notice it. this is precautionary more than anything. when i put the 3.4L in the car, i did not replace the friction surface on the LWFW even though it CLEARLY needed to be done. excitement overcame judgement.......

Oh! Its an Aasco unit.. For some reason I believed it was stock.

That vibration is also being felt by your knock sensors and you should see what its doing for your timing and power...

ah; good point. i hadn't considered that. DME retards timing as if tuning for crappy gas....

This is typically why I like this site - you learn something fresh every day.

I didn't realise (or even think of) the knock sensor being that sensitive in monitoring clutch vibration - and so retarding the ignition, which drops performance.....

Phew, I wonder what else can fail mechanically, causing enough vibration for the knock sensor to retard the ignition.
Perhaps this is the basis of J.R.'s new IMS failure detector that's due to be unvailed in a couple of months time????

Hey Insite,

When do you plan on taking your flywheel up? If you don't mind the company, I would like to ride up there with you as I'd like to check out Jake shop, heck I'd even be willing to drive... :-)

I am in Smyrna.

Thanks,

ian

Sounds good. I plan on taking it up sometime next week. Not sure which day yet; need to see how my schedule shapes up.
