Come on Monty....
This might be the combo for Novas and RBs but for OS VSpec type engines?? No I'm not talking 086 pipes.
053s are two chambers. The OS engines notoriously make stupid power with these pipes. However, I can consistantly show you 9 minute run times where with the other pipes listed (which are 3 chamber pipes and recommended by OS) minimize wheel spin and make 10 to 11 minute run times.
The other pipes that are in this catagory are the EB Mods pipe, Associated and JP-4 or JP-6. I don't know much about these pipes but I have seen them on top driver's cars running 10 minute sessions.
I would like to know about the new JP-6.
