if you have the 7At , you might have the same exact problem that I had for a complete year , no one was able to figure out what was the problem and it got worst by the time went

I had the luck of blowing my 7 AT at the drag strip and when they did the replacement they saw the flywheel which was badly cracked !!!

in the beginning when I noticied the problem it was at the beginning of winter , at that time we supposed it was some bad batch of winter gas.
but the problem never went away during the summer so we tried soo many thing.

by replacing the flywheel and tranny , I do not have that big extreme loss of power

mine was always like a clock at 6800-7000 and losing 40-50whp
then I started to have another other dip in power at around 4500rpm

Im only NA power with the 7AT ,

Ive seen a few other guys having a cracked flywheel .
