Hi,

Just a quick one really regarding the camshaft & lifters. I wish to purchase a newmans (sprint zvh) and had the following questions about getting it fitted etc.

• Is this a typical drive in / drive out type of job? I presume the head can stay on?

• Does it have to be set up on rolling road/ or is that for its fine tuning?

• approx costings for fitting ?

• maintenance wise will the lifters require tightening?

• can the cam be brought direct, if not who sells at a decent rate?

& finally, my car is currently a 2.0 zvh, would the type burton sells labelled (zvh sprint turbo) be the best choice?

Many thanks in advance

Dave

 

If you fancy learning how to fit it yourself then we could meet up and swap it over. Easy job to do, drive in drive out. Cam will need running in for 20 mins @ 2k rpm then it's good to go. Doesn't need setting up on a rolling road initially, you're thinking of adjustable pulleys which need the timing to be dialled in exactly to get the most out of the cam. Not sure if the lifters will need maintenance, maybe someone else on here can help with that one, but I'd imagine that once they're set (ie when fitting cam/lifters) then that's all you need to do.

 

Newmans sell direct, i should imagine Ł100 to fit is reasonable.

Rob,

 

Newman solid lifters will need adjusting regularly I'd say every 10k miles minimum, when I last cheched mine they were out by quite a bit and that was after only about 7k.

 

you cover some miles karlos

 

I do mate!
It's my daily, probably do about about 200 a week plus longer one off journeys.

 

When I phoned Newman and told them the spec of the car they advised me to go for the ultimate CVH cam rather than the phase 4 ZVH spec cam as it was a better allrounder for a road car.

I'm pretty sure Jano sells Newman cam kits cheaper than going direct. The lifters aren't hard to set up, just time consuming. When I did mine several lifters set first time and were perfect but one lifter Needed 45mins of adjustment. Just couldn't get it right.

 

cheers for the info lads.

Muz - how did yours feel after the install, is it spec'd to to kick far sooner than the zvh.

 

agree with u muz takes a bit of time but nothing hard just gotta be patient

 

i think i need to give them a call and find out what they recommend. Dont think i'll be fitting, still have nightmares about my xr2 days and not being able to get it right

 

I haven't actually used it yet so not sure how it performs. He just said there is little difference in the two and the CVH 409 cam was just a better all rounder.

 

Newman only do one of the shelf profile for an RST and it is very similair to a stock cam profile so nice and balanced, the other one they do is for a ZVH and will be laggy as fuck on a 1.6CVH.
I was told by Karl Norris that the CVH one was lazy like a Piper 285T2, but having now owned one I agree with what Christian from APT said which is it's more like a stock cam profile and a good all-rounder

 

the current one on my zvh is the piper one you mentioned, I have found it to be asleep most of the time and then decides to wake up. Not really interested in ragging the hell out of it top end wise, so I would prefer something to kick in earlier.

The cvh one seems best suited

 

Yeah my thoughts exactly mate.

 

My Escort had a Piper 285T2 in it when I bought it. Was laggy as fuck. Hated it.

 

Yep, 285t2's are a bit sloooow. When my standard cam ate itself I swapped out for a 285t2 and they're far too laggy low down. Much preferred the standard!

 

cool

Just need to get my car back from the garage who seems to be taking forever

Then its cam and efi !

 

Whats the response like on a Piper 285t - not the T2?

 

That is a great cam very similair to the Kent CVH34, much more balanced
Karl actually gets Newman to custom grind a profile that is very close to those two.

 

And if u had 2 decide between the kent cvh24 and the piper 285t?

 

AFAIK they are almost identical so either or mate, but I choose the Newman off the shelf profile which I'm very happy with.

 

Only thing that puts me off about the newman is the solid lifters... Are they hard to set-up and are they noisy?

 

Slow to setup, not hard, only noisey when out of tolerance.

 

Maybe a newman is the way forward then...

 

34 is not a great cam, just has a tuners name attached to sell it. In fact if you adjust a std cam to full lift its almost the same as the 34.

 

jano, what would be your suggestion for a 2.0zvh?

cheers

 

What tuner, I've not heard that before?!
I was simply talking about it's profile, if it only has slighlty higher lift or longer duration than stock then it is a good profile for most RST owners.

 

cvh 34 was an ahmed bayjoo indorced profile i think

Simon and nick from sitech have been advising me heavily on the build of my zvh, they advised on the newmans phase 4, but also juast is if not more importantly the head, it needs to be ported correctly to allow the gasses to flow properly otherwise the engine will run out of go too early.

 

As said by AFmotorsport its got Ahmeds name on it so it must be great.... :s

From his own mouth he has told me to adjust a cvh34 to the TDC mark on the head and it will be like adjusting a std cam to full lift. As most people who buy cam kits just fit them to TDC and hope for the best. He decided to make a cam that when set to TDC will be at full lift so that there is no need for adjustment. There is very slight differences between std and cvh34.. Imo not worth the amount of money they charge for it as it wont make great power and designed for an all round ERST with around 200bhp.

I have a custom cam profile from Kent for high power CVH engines which is what i use with solid lifters and twin springs. Not ideal for every car tho. Would need a large turbo, decent head and lots of revs to make the most of it.

If its a ZVH 2l i use newman camshaft.

 

Hello Jano,

It is very difficult to compare camshafts looking at the 0.006" lifter rise specs. These are the specs the camshaft manufacturers use - Kent, Piper and Newman.
example:

CVH285T intake open/close exh open/close

16 btc/74 abc 74 bbc/16 atc full lift (intake) at 119 degree atc

CVH 34
20 btc/76 abc 76 bbc/20 atc full lift (intake) at 118 degree atc

Newman
24 btc/72 abc 72 bbc/24 atc full lift (intake) at 114 degree atc

Ford HO roller
22 btc/74 abc 74 bbc/22 atc full lift (intake) at 116 degree atc

This is how the camshafts open and close, but different cams will have more or less agressive valve opening rates - which the above specs do not show.
We require additional information like camshaft duration at 0.050" lift and 0.100" lift.
Then we could compare camshafts in a performance sense.
Has anyone ever mapped out a camshaft with a degree wheel to come up with the 0.050" and 0.100" duration specs for the different cams?
This would be incredibly usefull.

Cheers

Perry
