How do you like the TPI valves Im thinking of doing a set on my RX-1 and 160 mains and red holtz
They work very well without sacrificing fuel mileage, I was getting the same as the 05 RX-1, The Mach Z was getting almost as good, the MXZ 700 and the Rev 800 where drinking it up

BlackJohn recommended them for better accelleration and I believe they work well

Ok so you have been setting up the stock set up and are getting great results. Is this set up trailable or race or both? Congradulations on your findings by the way. I hope to be as successful messing around with mine.
