New NHRA Rule? My local track is now requiring cars running 11.99 or faster to have a 20lb radiator cap. Where can we get these that are properly vented for our cars? I want to take my new combo to the track next week but need a 20lb cap!Any ideas?

That's a crazy *** rule. Why a 20 lb cap? just plain weird. I can't think of any good reason for that rule. The only thing a higher psi cap does is raise the boiling point, but a car is suppose to have an overflow tank anyway.
I've ran a 7-9 lb cap for the last 6 years. I switched to it one year when I had a head stud leaking problem and just never switched back. The lower psi cap helped stop the seeping coolant and I finished the season without having to pull the heads.

He's either trying to show off, make a joke or he's got a screw loose. 
As for the cap, we've been running the bigger caps for years. It helps keep the track dry, and if your motor is done right, nothing will leak. I think I have a 26lb on both my cars. Never had any problems.

After a few guys blow their upper radiator hose off those shitty chrome SBC thermostat housings and spray down the entire track a few times they may change their minds about that 20lb cap thing..
wntstogo100- whats the difference between the new z06 that will do 190+mph,thay don't have a factory roll cage. thats worse then me,i can't go that fast. fact is you crash on the e-way or track your messed up cage or not. just so you know.....if i were dead....just like all dead people....THEY CANT SAY ANYTHING. or are you trying to say you're like the boy from that movie....are you seeing dead people???
