Kent vs Piper vs Burton Power - which cam..?
Morning all...
Ok - I'm confused..... which isn't difficult..!  I'm looking for a new cam, initially for a 1600 pinto, which will be transferred
over to a 2 litre.
Big problem is 'which cam' as although the 3 usual suspects use the term Fast Road, all of them have different duration and lift etc.
Question is, whats best...? Base spec is bike carbs and Megajolt, everything else is stock. Whats the best in terms of lift and duration, as
I've read the Puma Racing pinto guide, and I'm still none the wiser...! Practical usage and experience is what I'm after..!
So, who's got what..?? FR32..? FR30..? BP270..? Ultimate Road..??
Any pointers greatfully received..!
Cheers
Pete

I got a fast road cam in my Falcons pinto, ho ho sounds cool and rather lumpy, quite a difference in the power too.
oh yeah and it was a Kent one

I have FR32 in 2.0 Pinto with ported head and 38DGAS. It is nice on tick over, smooth power delivery, classed as fast road but to me seems a bit tame
for one of our cars. Car needs good set up so might be doing the can an injustice. However if you dont want a lumpy tick over and do need some
tractability below 4000 revs (ish - joke) then it could be the one for you.
Mookie has FR33 in his hill climb car. Ive heard generally good reports about the FR33 in a well ported head properly set up apart from they can come
on cam with a bit of vigour at times (great when you want it, not so great if you are already on limit of traction in wet etc).
In my mind most of the suitable cams are a bit of a compromise. most engine builders have their favourite. One reputable builder said my cam was no
good (its not really for competition engines) and preferred to use a Piper A8. Another builder highly recommended the FR33.

I'm running a Piper 285 in my 160Bhp 2.0L lump.
Pulls like a train from 2000-7000RPM.
Are you a Mac user or a retard?

FR33 cam - I find that providing the carbs are set up properly then I get a very good tickover at 900rpm. The FR33 is not a wild cam but a very good
compromise to be used with a gas flowed head.
The cams to be careful of are the race cams which have a poor/lumpy low end.
The FR range - Fast Road are designed for fast road use which also means that it will be ok to use on the road.
The only thing really is that if you get a FR33 and use it in an unmodified 1600 then you won't get the benefit of it.

I asked the same question just before Christmas and came to the view you won't get a straight answer.
Click Here for Link
People say don't overcam but then tell you the Piper 285 is not "wild enough" and the A8 is a good cam. I did a full summary of all
the available cams and there were simlarities between Piper and Kent and Burton as you might expect. I think the A8 is pretty close to the Kent RL30
for example.
I've read that high valve lift is more desirable than long durations and that long durations don't come into play until you hit higher rev
ranges.
But then most Piper & Kent performance cams seem to have longer durations around 300+ degrees.
I found it very confusing and in the end decided I'll just go for one and see how it goes.
I have added megajolt to mine though on the basis that I can maybe go for a wilder cam and still have a reasonable idle. All will be revealed when I
get my rebuilt pinto back
I used to be apathetic but now I just don't care.

With your 1600 , which I assume is unmodified, you will be just wasting money, especially if your aim is to change up to a 2ltr at some time in the
future. My advise would be to stick with the standard one, will be plenty fast enough. Then when you get your 2ltr, rebuild with gas flowed head, and
then fit the high lift cam, NOW your SMOKIN' . Regards, Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

The idea is take the cam out of the 1600 and put it into the 2 litre at some point in the future, and I don't really want to buy 2 cams hence
asking whats worth having.
Thanks for the comments about gas flowing etc, its something I've been thinking about
Cheers

Why not upgrade now
For the money you will spend an a cam kit you would be far better off changing engines for a 2.0Ltr straight away.
The gains would outway those from camming a 1600 and would save you some money.
If you already have MJ and Bike carbs then the engine upgrade would not cost much.
Summer's here!!!!

Looooonnnng story... but in essence, a good friend who has spent far too many years building and rallying everything from Mk1 Escorts right through to
works Cosworths is building the 205 bottom end, and its a case of wait and see for time etc as he's currently in Qatar.... And I'd like to
drive it this year...
Piper 285 sounds like one he mentioned, but also mentioned the 'GT' cam..? Anyone shed any light on that..?
Cheers

I thought cams were not easily transferable, in that they "run in" to their situation/tappets etc. & if you move to another
installation it all goes pear shaped.
perhaps that's no bad thing for a cam...
