how can u tell if its worn?

 

If it's fitted to a CVH and was made by either Piper or Kent, then chances are it's worn.

Seriously though, it's hard to tell because with Hydraulic followers, they take up alot of the wear, so the only real way to tell is to take it out and look.

 

which is the best cam to get? i believe i got a kent cam in there at the moment. im running about 16psi on a 1600cvh with mfi. ive heard good things about the newman cams. which is the best to get for me? and how much will it set me back?

cheers.

 

works out just over £300 if u buy the cam, double valve springs + caps and mechanical followers (essential)... add onother 80 quid if u want the newman vernier as well... good price.

 

ive had a worn cam twice in the space of months that was piper tho the symptons i had was the first time the car wouldnt rev past 5k after that it would miss fire, the followers were getting stuck. and the second time there was a slight miss fire at idle and was getting that tappy way, im now back to the standard cam and feel its the best the cars went boost seems to be a lot stronger and a better drive hope this helps

 

yea i heard the standard cam works well. However, shall i get a standard cam or should i go for the newman?

 

Depends on your spec. Under 200bhp and I would say that the standard cam will be fine.

 

im running 191bhp @ 16psi with a half pace cooler. I will be changing it to the GRS intercooler and will be uping the boost to 19psi. [/code]

 

That's not with a standard turbo is it?

 

no mate, its stage 1

 

There isn't a CVH on the planet without a worn cam

From all the experiences i have had, if the cam is worn enough to affect performance, it will also be tapping as it chews the followers up and they can no longer take up the clearance in the valve train.

you can also tell a lot by removing the cam and inspecting the lobes

 

are u sure?

 

i have a kent cvh 35 kit in mine and seems fine! really quiet topend too...

 

Last week we pull a cvh 35 out of a 2.1 which has been running 30+ psi and done about 10k and in a word it was f@#ked.

We also have a 1.6 rst running a piper cam for the last 7k and now wont rev about 5k so thats jsut about to be taken out and inspected.

Cheers,
