Gary, I stood on the tarmac as you guys took off and flew South. I told you my flying days were over, but I have to say it wound me up again seeing those RV-8's. I'd love to take on another plane but I just don't have the dedication to spend 5000 to 6000 hours of building. I think I need a Zanax !
Anyway...........back to the topic at hand....... I got a call from Lance at Superformance at 6PM after you left. He told me the story behind the Wilwood / PBR /back to Wilwood issue. It was partly a manufacturing issue, but there is more to it. He seemed straight forward and honest. This is based on the fact that what he said made sense.
He's sending a transport to the house between Monday and Wednesday. He's supposed to call Monday to confirm the date and time. Apparently, the new 41mm with a vacuum pump will cure all our woes.
This is the same setup Steve called about and has added to your car. Steve said he can't fault it on the street, but wanted to try some track time to verify it is track worthy. I should know more after the Cobra Bash in Reno in about 3 weeks.
There's no absolute answer why an only 9mm larger piston would make a huge difference. Like I said earlier in the thread, in theory the 34mm should work. Willwood said the same thing to me on the phone. Wilwood did mention, as did the boys down at the Corvette race shop here in Roseville, that the smaller caliper may not have matched the valving in the master cylinder, and the 41mm internal volumn ( or some kind of s*
is a better match, thus, better brakes even without the vacuum pump.
My car will remain in Reno until the Bash. I will have time on the 160 mile drive home to test and will hopefully leave my last post on this thread the next day.
PS........ Don't forget to have Steve BED the brakes before you pick it up for that 500 mile drive home. He probably already did, but you may want to call and make sure.
You have my number.......tom
