ie a kent fast road inlet cam, and a standard 2.0l zetec zorst cam??

basically before xmas me and my mate replcaed the head on his car and while timing the kent cams we noticed that the zorst cam had snapped while i was cranking over by hand!!??!!

and kent wont replace it the coonts

so will i still get any benifit just fitting the inlet cam??

i guess i would?

 

 

I have no idea on a n/a engine, but on a turbo one it can help spool up.

However, on a turbo engine with mixed cams, port sizes become an issue or the engine can melt if not correctly specced to match the different inlet / exhaust cams...

 

ok, cheers mike

 

Mike whats the benefit of using different sized cams ?

IE

A BD16 INLET AND SAY A BD15 EXHAUST ?

Why is it not preferable to just run 2 16s ?

 

Read my post again, it clearly says in there .

And it would be something like a standard cam profile (BD8) and a BD16 to help spool up.

 

So running a 16 and a 14 is useless then in aiding spool up time ?

 

You want an inlet cam that can get as much gas in the engine as possible and then an exhaust cam that holds it in the cylinder long enough to give good pressures so that when it evacuates the engine it aids spool up. This is where the correct port sizes are essential, as it can melt if you get it wrong. Can't tell you any more about the port sizes or I am giving away Harvey's years of dyno work .

This is why the BD 10 cam is so shit, it has the same duration as a BD16 (264°) but no lift, so it gives no low end power whatsoever, for only a very small gain at the top end.

 

I Run different cams on my engine

But to be honest i would just mix it if u dont know how its going to work as it could cause poor running if not both properly speced!?
