the pressure regulator is an aero motive boost reference return style
I did sick week in Florida. but ripped the pinion in two pieces on Sunday. had a new rear in it that night at 1:00 AM but then found out the transmission was broken, we later found out it had broke the input shaft
I am in the process of getting a new rear under it (all strange products) 3.0 gears. and with that I will loose the heavy steel wheels. that will be a 70 lb rotating mass reduction in weight, I'll scale the car again after its all said and done. I believe on pump E-85 and below 15 lbs of boost I can go to my cage limit of 8.50's
if you look on the internet at sick week and Jeff Lutz I was lined up next to him. It had rained that morning and my rear window leaked water into the trunk. as I did my burnout water leaked under the car, Someone said I was leaking the starter backed me up didn't see any water pulled me back in It spun really bad. let off and it wheel hopped bad enough to break those parts and it came loose on the next run in. the middle of a big wheelie.
