Hi all,

 

does anyone have any guidance on the cam timing to use with the minispares EVO 1 cam? I'm talking about how many degrees BTDC or ATDC to set it. I'd like to have better low end performance so i'm thinking a lightly advanced setting.

 

Im using a CAHT-88 minispares head and i have +40 thou pistons and the CR is 9.0

bump. minispares website says it should be timed at 107 deg for optimum performance.

 

wondering if this is the case for my 998 as well?

[BaronVonchesto]

I guess people haven't really used this cam with a 998?

 

I'll stick with minispares recommendation then.

If it's a new chain, I'd go 105 degrees to account for chain wear after installation.

I built a 998 Mk.2 1969 Cooper engine with this cam and apparently it goes very well.

im using a new high strength simplex chain. i dont think it'll stretch as much as 2 deg surely?

I bet it does. I did a test one time and a quality Duplex chain stretched to retard the cam by 1.5 degrees after 1500 miles.
