WHEN THE RPM HIT 6000 RPM STOP GOING ANYMORE BUT NOT AL THE TIME
IF ANYONE KNEW PLEASE TELL ME WHAY ?

 

make sure cars warmed up all the way to 3 bars on temp.

 

Yes, you are not letting the car warm up. Take the time to read the owners manual. There is a lot of good information in there. The car will not go above 6000 rpm without 3 bars showing on the temperture gauge. This is to protect the car from those that would run a car not warmed up hard. I would not even consider a V-Tec at that point however I have an engineering background and rely on high performance equipment to keep me alive. BMW on their M series S52 engines requires 140 degrees of oil temp before opening the engine up. It is interesting that the engine water temp is at normal operating temperture long before the oil temp reaches 140. Seeing this I have added even more time to my S2000 warmup before turning it loose.
