cam makes/specs??

[Raymond Daley 4]

Ok just just wanted to ask if anyone knows this cam maker.. on the back of the cam its stamped.. CM250*S and also has WRC.. any thoughts..

 

 

[ando76 4,354]

Wade perhaps (wade racing cam - WRC).  Nah - I've got nothing. 

 

You can send it to one of the many cam manufactures and they can run it up on their 'cam doctor' and tell you exactly what the specs are.

well after using my diel gauges I have the cam at 

 

lift Ex 501'

lift In 496

Duration @50 Ex 226

Duration @50 In 249

and Lobe sep 114.. 

 

I can't see that being right tho..

its a dynotech cam cm250 I thort was a 214 214@50 495lift

I have a few in the shed ill take a look tomorrow at the spec sheet and part number

[wagoon 2,429]

Well I had a nice witty reply all typed out then Pro comes a long and makes it all irrelevant. Oh well better that you have the correct info from someone that knows stuff than some comment from a halfwit that knows fuckall.

214/214 is CM251. Don't know what CM250 specs are but is a standard camshaft replacement

I have a few in the shed ill take a look tomorrow at the spec sheet and part number

so would the S at the end mean a solid cam?

[PRO250 1,506]

zero idea mate and banno may be right I think I have a list in the shed for the dynotechs ill see tomorrow

For the same duration at 0.050", solid will have a longer ramp-up than a hydraulic, so the advertised will be much longer.

 

The specs you measured don't make any sense. A split-pattern cam always has a longer/bigger exhaust.

[slydog 7,873]

Ring Surecam for a cam that suits your needs.

[Raymond Daley 4]

I think I will just get a sure cam.. I have had his cams before and they are great.. 

[Raymond Daley 4]

ok so after look at it and thinking about i redone the cam.. and this is what i got.

 

lift Ex 574

lift In 498

 

Duration @50 Ex 280

In 280

 

cam centerline Ex 250 after TDC or 70 before TDC

In 105 after TDC or 75 before BDC

 

but I can't work out the Lobe sep.. can anyone help with that?

[Raymond Daley 4]

Oh and just to let everyone know that the cam numbers stamped on the back " CM250S " stands for " CM250 " is to suit a 250 xflow and the " S " stands for a unfinished cam so its just a blank cam that other cam makers buy like wade cams or sure cams or cam tech.. 

[Raymond Daley 4]

sorry had a brain fart.. its 107.5 lobe sep..

[gerg 10,871]

Yeah that sounds right it's in cam degrees, not crank.

 

but the 280 duration at 0.050 sounds way too big. Most performance street cams having that much lift have around 280 advertised and around 215 at 0.050.

[Raymond Daley 4]

it was made for a speedway car..
