Hi all,

Looking at my engine build, i have been told that the kent range of cams is very good in profile but wears very quickly due to shite materials and presumably bad surface treatment. Has any one considered getting a piper/kent cam nitrided? I don't know what spec/grade material they use for the blanks either.....

Or does any one know of any other surface treatments that could help us all out? if we find a suitable process i am happy to be a guinea pig etc.

maybe we should see if there's enough interest see if newman would copy a kent34 cam for us as they do custom grinds

Newman make good enough profiles in their own right, and I've always been under impression Piper make softer than Kent anyway...

That or call Martin Hadland at Reyland, he can get custom billet cams made up for £150 or so IIRC.

Yes that was the other option, i mentioned it in a thread a while ago but didn't get any replies, Getting Newman (or who ever) to make up a batch of 10 custom cams shouldn't be too bad, with the 34 profile etc you could keep the hydraulic lifters too. .

I guess if anyone is interested drop a post, if there are enough i will get onto them.

would be nice to know the spec of karl norris's custom cam as we might be going to look at the very same thing he already does but save ourselves the hassle of it all and for the revs mines going to be running solid lifters only sorry

Ad4m RST

Solid lifters not an option then? Newman have profiles just as good as Kent 34 without all the group buy hassle, or am I missing something?

project rs

they only do 2 of the shelf ones, 1 is to go with the zvh engine other is for cvh engine and is a bit lazy like the piper t2 and i am just after something a bit closer to factory cam and spoke to someone running karls custom one and he said it's the best he's had in every way

Who makes karl norris's cams? and yes from what i have heard newmans profiles are a bit lazy, good for some but not for others. You can still run solid lifters I would prefer to run hydraulic lifters which you can't really do with the newmans profiles i don't think?

Rob,

karl norris gets his custom cam of newmans sorry i didn't make that clearer earlier

Sounds like he's done what we want then lol may even be that he's based it on a kent/piper profile anyway.

I've been under the impression that it's not the cam only that is the problem, it's the bad hydraulic lifters available that cannot cope with harder cam material either. I think making their own solid lifters was not a choice by Newman, they were forced to go that way.

Yup Newman do only one CVH turbo profile and it's very very lazy!
Spot on!
I think it's very similair to the Piper 285T (not the T2!!) and Kent CVH34.
Also true, the lifters are made from equally poor material and the bases end up looking like the head of an old chisel!!

i use piper t285t2 high boost cam its been a good cam but ive had it in for 8 years now im goin to remove to measure cam up .gota be honest apart from being hard to setup correct .because of change in climate e.t.c im happy with cam . its very good from low revs to mid range pulls like fuck upto 140 mph ish .

Rob have you looked into the PE SX248T cam? I beleve it is close to a kent 34.

Rob,

last week a hydraulic lifter sized solid and destroyed my kent 35 cam only five months old,so now im looking at something else,i like the profile of the 35 but have lost confidence in the quality.......
im reading alot of you like the 34,is is that good?

juffer

I have ran one for a year and my mate had the head befor me with it in which he had with there system 2 convsion about 8-9 years ago. Its still going in mine with the followers.

Its about halfway down the page. Thinking about it now rob i think piper grind there cams but i beleve its like the kent 34 profile.

Seems the old ones were fine on a healthy engine. I has a 35, and it didn't wear at all in the 5 years i had it in. Aweome with a stage 2 turbo too.

Pete frst

perhaps i'll stick with the 35,but with ford lifters and double valve springs.........

simsytall

i run newman cam,solid lifters,d valve springs nothing lazy about my engine imo,cam works best btween 3-6rpm pulls like a train in every gear
