What cam ,springs and lifters are u using cos i cant get mine to rev above 6.2k its got a piper t2 and stronger valve springsin it , its pissin me off a bit now

 

I'm using a Kent CVH35 in my S2 and really rate it. So much so my Fiesta will be getting the same cam

Why do you want to rev past 6200 though?

 

cos im gettin full boost at 4.2 ish and soon as does its on the limiter want a wide power band and cos its still makin power

 

Fair enough. Not sure how off the shelf cams will work at higher revs may need to chat to Kent/Piper/Newman direct and see what they say

 

jamie said was goin to ring newman and see wat they could do with the cam and to stop the valves bouncin, just wonder wat people like tim, oli , tony were usin to stop this

 

Jamie is pretty shit hot so leave it with him and I'm sure he'll come up with the goods for you

 

is it not the management choping back the ignition timing? ive got one of those 7200rpm revlimters on my mfi rs, and runnin 285t2, it revs fine al the way

swappin cam soon tho

 

have seen a few rs turbo revving over 7k..they all have worked heads tho..

and newman cams

 

Thats good power so far Stuart! If a little low on torque compared to some?

 

Im making peak power at 6100 rpm and the limiter is set to 7000 rpm.

Im using a Newman cam with the solid lifters, dont know much about it as it was all fitted at AVA

 

When you say it wont rev above 6200rpm are you refering to where your power drops off as in its peak power?

or

Your car physicaly wont rev beyond 6200rpm (say for example) like hitting a rev limiter at 6200rpm?

 

INTERESTING AS ANDY SAYS.

 

From the way it has been written I would assume that it's as per this one?

 

Mine is a std cam, and with a t34, full boost at 3600 and so far it's mapped to 6,5k, and wants to rev past no problem. What is actually happening? U shouldnt be getting valve float - are the lifters pumping up?

 

yes the lifters are , its not the rev limiter

 

newman cam with solid lifters then see pumaracing for his double valve spring system you wont suffer valve float until you pass 8000rpm..

 

what oil is in it? Although solid lifters will cure it, they shouldnt pump up at 6.2. Ivr gone past 7k a few times with no problem. U could try a new set if u dont want to go all out with the newman.

 

havin a newman cam and kit fitted next week . hopefully will sort it and can rev it to 7.2k-7.5k

 

if it's the lifters, then the newman will defo sort it No more cam wear problems either I take it it's being remapped? (It HAS to be) Keep us updated

 

yes the map can be finished off then , should b done next week

 

change the springs!! have some custom ones made

 

better be we got a date at the pod

 

mines mapped to 6750 rpm with a cvh 35 cam

 

it still goes now,dont worry ill race if its done or not

 

just had a newest cam from newman fitted with double valve springs and solid lifter, revs to around 7.2k now .

 

should sail past 300hp now

 

cool, how different does it drive?

 

already has mate maxed out the jamsport rollers

 

it pulls like fuck 2 7.3k now, more probs with the springs ( fault piper 1s ) or lifters , with the new cam its makin power up 2 7.2kish

 

nice one, what about where the power comes in? Is it noisier (tappety?)

 

 

glad its sorted nowt like a bit o revs lol ave it

 

Tim, how u doin wit clearance intercooler/turbo wise?

 

Not 2 good rethink on the cards.

 

i was looking at mine today, and it is so tight. Think best would be a manifoild moving the turbo toeards the box.
