Colt Cams C.709 I.S.
223 deg duration @ 0.050" lift; advertised duration 261 deg; lift 0.326"
Inlet and exhaust cams the same.

I bought them because they are a straight "drop-in" and run with the
factory ECU. They are in the car now, and I hope to get back on the
dyno in the next week or two. See if they make 8 kW :wink:

Robokill I understand that there are a lot of variables involved
in making this work. That's why I won't be too upset if any one mod
does not make as much power as I expected. However, I hope that by
taking a dyno reading after each mod, I can provide some hard data
that will be of benefit to others planning their own improvements.
