As Dan.

I simply will not buy Kent or piper, as it is 250 pounds for something which simply will not last. THe motorfactor cams i have been using jabe been holding up very well. £80 should get u a new cam and followers. I am on a big turbo and big head, so the std profile is quite suited, it sits at 6800rpm no problem - it will go higher i think, but the engine isnt mapped above there yet - although this will be happeneing very soon.

My plan is to goto Newman eventually - they are proven to be the most reliable.long lasting. They are made of a chilled cast - no other cvh cam is - they must be used with newmans own lifters, as any others will fail. The downside is that it is a solid lifter cam, which require many many hours for initial setting up, and will be constantly noisier than the equiv hydraulic profile - which should be silent. Although the wear is minimal, some will occur, and hence the valve clerances should be checked a minimum of every 6 months, possibly more. When i get one in my car, it will be a true test as the car covers a lot of mileage - we will see just how practical they are.

The reason i haven't got one yet: You are looking at well over £300 for everything. The engine is still being developed, and power is increasing with the std motorfactor cam in place. Once i can get no more from the std cam, then i will try the newman. For now, the std item provides a very responsive item.

If you want more power, then i would goto a bigger turbo and keep the std cam. You will gain more power, with increased reliability due to the lower temperatures a larger turbo brings.
