Hello.
At http://www.pattakon.com/vvar/HelpRoll.htm you can see another version of our variable valve actuation system (this time with rollers).
The system is so close to Honda’s VTEC (in S2000, CivicTypeR etc) and at the same time it is so different in operation, you will be stunned.
Just take a look.
Thank you
Manolis Pattakos
