S2 been of the road for a while.
Needs m.o.t'd & then set up. I picked up a piper adjustable cam pulley.
Is there any point in installing this?
Engine is standard 1600, balanced,stage 2 head,piper 285t2.
chipped ecu, pace chargecooler,Standard T3,uprated actuator running 15psi.
If it's worthwhile I'd rather install it before spending £150 getting
the car set up.

 

I put one on mine before I had it set up and they adjusted it during the setup. Gives you more adjustment to advance/retard. Worth doing as you'll get the best from your cam then.

 

They can be useful if the cam timing is set up correctly with a degree wheel and dial gauge.
Otherwise kinda pointless.

 

I was told by my tuner the standard one is the best?? Not sure how true that is

 

I dont agree Perry, when on a dyno you can adjust it to get the most out of your engine, or move the power band to where you would like it, if running a big turbo for example you might advance it a little to decrease spool up time.
Without one nothing can be done!
Totally untrue!! lol

 

Then maybe i should get one

 

Definatly mate

 

Yes! If the car is properly set up on a dyno. I did not read that he was going to have the engine set up on a dyno - sorry for my confusion.

A good starting point is the cam manufacturer opening and closing events in any case.

Karlos always disagrees with me!
maybe because I am not English

Cheers

 

lol I do not always disagree with you Perry, sorry if it seems that way!!
But in this case, as he is going for a dyno session and has a 285T2 he could benefit from a vernier... Although with only running a stock T3 both the cam and vernier are a little pointless IMO.

 

karlos is a little like chip, if he knows better from experience then he will argue his case, so people who might be reading dont get the wrong info

 

I think unless you are going to play with the advance/retard on a dyno then there's not a lot of point, you can set it up to where it 'should' be but i've found that even then they are never in the 'right' position for optimum performance.

Occasionally, you get a camshaft that's in the right place to start with even using a standard pulley, so therefore a vernier is not needed, but you don't know until you fit one and advance/retard and power run it on the dyno.


Karlos, I wouldn't say a cam and a vernier are pointless on a standard T3 rs turbo, sometimes they need a higher rev limit but there's still definately gaines to be had! you don't need boost for a higher peak power.
Camshafts shift peak power higher up in the rev range, revs = bhp.

 

My point there was that in this instance the turbo will limit him to about 185bhp (nothing to do with boost, it's about flow, a stock T3 will not flow enough to make use of that cam) and whether he has a vernier & cam or not makes almost no difference... Also the 285T2 is a very very laggy cam and not suited to his spec at all, people chasing big bhp say high 200's might benefit from it as it flows well up top but is shit low down and midrange.
A stock cam is actually quite a balanced profile and fine for anything up to and around 250bhp.

But back to the original question... As he has it he might as well fit it as it costs nothing.

Just my thoughts anyway fella's!

 

Thanks for the replies.
Bit dubious myself about the 285t2 on my engine but it was installed ten years ago and never driven the car since.
I actually have a stage 3 big valve head which has a power engineering cam
(sx 428 maybe) which would probably suit the car better if I could be arsed swapping it but will probably just keep it for a new engine I'm building.

 

so with adjustable cam pulley and newmans cam if you retard you get less turbo lag and if you advance your turbo kicks in at higher rpm is this right????? or am i missing something?

 

Sorry to throw this up again

I got a burton pulley today off an eBay seller. My plan is to keep the cam standard unless its found to be knackered or can pick up a after market one cheap.

Is their any point installing it. For the moment she will be standard , I have a pace i/c, magnex exhaust and it will hàve a k & n panel. I will probably get a chip in it too
Cheers

 

Yes, but at the cost of a few BHP.
Not unless you have it setup on a dyno and even then with a totally stock engine I doubt there is anything to be gained.

 

Cheers karlos

Either il keep it in the parts bin or else throw it back up on the bay
