Is it possible to use standard ford valve springs with a 285t2 cam.
is anybody doing this with good results?
if not what are the best anti coil springs, not happy with my piper springs.

Thanks.

 

Out of interest, why aren't you happy with your Piper Springs??

 

To be honest i may be jumping to conclusions.
A couple of replies i had about a recent post of mine suggested valve float or possibly a worn cam but the engine is only 3k old, i run the cam in properly. I did notice that my original valve springs were a little tougher than my new piper springs, obviousley due to less material

Basicaly my car is loosing power between 5 and 6 thou.

 

I'd go for ford ones mate and there only about 4quid each.

 

What do you mean by losing power between 5-6k? Is it noticeably running out of puff? It could simply be all done by then. What Turbo is it?

Is it Misfiring?

It could be lifters. Thats quite likely.

 

many years ago we used a piper T2 cam with standard springs and it wore out in 500 miles and knackered everything

so i would so do not use standard springs.

 

cvh cams seem to be shit at the moment. id have a look to see if there are any lobes left.

Peak power around 5k is not unusual anyway, depending on spec.

 

the best cvh springs to buy see david baker at www.pumaracing.co.uk thats what i am using they are his own system he has made due to the problems with the cvh valve springs going coil bound u wont get any valve bounce with the turbo rev range tested to 8000rpm...... for cams see newman cams excellent quality and will out last kent and piper cams, piper quality are not too bad but kent i'll never buy one again

 

It is possible that the engine is giving up, but i thought a uprated cam pushed the power band further up the rev range allowing it to rev higher.
Its the way it looses power, just seems to stop pulling at about 5 thou, doesnt sound right after that.
Im using a turbo technics stage 3 blower and the engine runs sweet, no misfire allways runs on optimax. Everything is new and set up right. The lifters are pipers own, 3k old.

 

thanks for the advice, dont say much for piper does it mate.

 

Just read puma racings section on double valve springs, seems well clued up so im having a set
Where can i get a newman cam from?

cheers

 

I recently raised my rev limit to 7050 rpm,im buying a newman cam with double valve springs will this be ok at that rpm ?

 

thats the combination im gonna try, just need to know where to buy a newman cam from.

how did you raise your rev limit?

 

go direct to newman for there cams www.newman-cams.com i had one of there off the shelf cvh turbo cams but then i wanted one more radical then the cvh37 so they done me a custom cam these are the only cams that will last in a cvh engine email david at pumaracing i have just spoke to him no problem doing you a set but he has so much work on.. kent and piper springs are shite they just dont work right

 

Thanks mate, i have been in touch with david newman, he is gonna supply me with double valve spring setup, solid lifters and a cam

 

ask him whose double valve springs they are because i thought that newman dont do any i could send you some photos of my setup if you pm me with an email address

 

Theres some pics of the puma setup in the American Escort thread from Bradescort - check it out top stuff.

 

david at pumaracing fitted his double valve springs when he done me one of his 45mm inlet valve head ported cvh heads

 

newman tell me that the double valve springs are the same poundage as the standard springs but they have better harmonics.
Just been out in my car again and it is really anoying how it gets to 5 thou and looses momentum, even sounds different through the zorst.

How come on this months performance ford the piper kit they use comes with double valve springs? recent upgrade by piper?

 

I've read his article on his website, sounds like the best head available, lots of work gone into that one

do you use solid lifters? is there any point me purchasing them if im only planning on revving to 6200.
Do you think the newman off the shelf turbo cam will be enough. i.e is it a mild or wild one, on comparison to 285t2.

 

newman cams only work with solid lifters because they are chill cast blank Hydraulic lifters would knock the cam lobes out quite quick i dont know the profile but ava use the cams in all there cvh heads one of them shows peak power at 6400rpm the cylinder head is excellent gives 50bhp over any stage three head u care to use

 

I bought a fuel ecu off a guy who works at turbosystems m8.

 

So it must be raised via ecu mod then. Something else on the to do list.lol.

 

He said the rev limit would now be governed by the chip,and that turbosystems who chipped my car set it at 7050 rpm,and it does rev to 7 000 now lol.

 

are you using solid lifters? what cam are you using.

 

Nope , anti pumps and double valve springs. going to change to newman cam and maybe solids. running a piper t2 at the mo.

 

I am currently running a t2 and anti pumps, gonna go for a puma racing double valve spring setup.

 

Then go rev the fooker.
