Yeah everyone seems to be raving over the cooksport springs.
Yeah, they seem to sit at a nice height, identical to GMax ones as well apparently.
Things on here go through phases of being very fashionable, think its those springs this week, lol
197 cams give a noticeable gain? Heard someone say they give rough idle?? Just a case of a cam swop and some mapping??
With the RS2 inlet manifold they certainly improved the top end, yes just swap cams and map, still works with 172 dephasor etc, although MWMSport have found that the standard 172 cam timing isnt what works best on the 197, so I got Mike to time mine in appropriately based on his findings as its not something I have played with myself and its such a ballache on a 172 to keep going on and off the rollers and pulling it apart altering the timing etc.
Ours has a very slightly lumpy idle, it sounds cammed but not in an intrusive way really.
