Brian,
were you breaking hyraulic valve lifters or were you having spring and or valve failures? What RPM were you running these hydraulic roller lifter engines to? Had you had the hydraulic roller lifters modified to stop them from 'pumping up' at high RPM (i.e. over 6000rpm)? Were the valve springs in the engines the std ones that came with the Edelbrock Performer heads or did you upgrade these?

On another note, did you ever have any problems with running main or big end bearings due to oil starvation while using the Panoz supplied wet sump set up?

The engines were all sealed panoz motors or ford crate motors. So I doubt they were modified heads. We ran the sealed RPM limits which I think were 6000 rpm or something close (I cant remember). The motors broke from a few situations. Mechanical overrevs letting the clutch out a bit too soon when braking hard and downshifting from 5th to 2nd gear. We seam to have bearing wear at about 40 hrs. which needed a refresh (our current motors go 100+). We broke some from a mis-shift but that is to be expected (not really from our new engines which could take an accidental 9k overrev). I feel if your going to build a motor for a race car it should be designed to take ABUSE!

Our cars had accusumps for part of their lives. Maybe the bearing failures were because of the oil starvation. I am not an engine expert but I had 2 engine builders tell me the motor from panoz is a POS and not meant for a race car. We built a motor for about 3-4k more and it has held up GREAT.

We didn't run last years runoffs. We have been pretty lucky we've only blown up 2 motors in the last couple of years and we have 4 cars. Only one of the cars has a good enough driver to do good at the runoffs.

Coach0187, did you happen to buy one of your cars from Tom Mitchell? If so, you have my original Panoz from back in 2000-2002 seasons. It had been a very, very unique PPG purple to gold flip-flop color. I real crowd pleasure at the time.

BTW...I'd be interested in knowing how you put your car on a diet!

meeee too!

Yes this is the car Tom had, I worked for Tom and the guy that has the car now bought it and all Toms racing stuff ( me included ). I'll send you a email about the weight.
