I'm experiencing this now. I did the tone ring TSB and that didn't help. I had a crank relearn done but with winter upon me, I haven't gotten to test it since. Mine is a surging at cruise. It is primarily a track car and at WOT it does not seem to happen. I did notice it on the banking at CA...

Don't forget the movie To Please a Lady.

I wasn't that fast but Auto Club Speedway was sure fun.

I've gotten my Big Willow time down from 1:48.99 down to 1:42.76 on 5/8/22 on worn Cup 2's.

I weighed the stock GT350 flywheel today. It was 30 pounds on the nose. That was without any hardware.

Do you think it will hurt low end torque much?

Is there any significance to car number 406?

I got mine yesterday. I'm pleased with it. Glad you pout this together. Now to get my FPRS GT350 into next years edition.

I just ordered mine.

Doesn't our flywheel act as an additional vibration damper? I wonder what this will do to engine vibration.

So I picked one of the 17 FPRS GT350's. It is the car I did my school in. I went 5/1/2016. I'll post some pictures and mods as I do them and if I can figure this all out. Especially how to shrink photos. I plan to make this primarily a track and HPDE car with occasional trips to car shows etc.

I got my old school car #17.

I usually head down to Willow Springs in CA. There is an SCCA autocross group that alternates between Great Falls and Helena but I haven't joined them yet.
