In the traders room there is a pulley manufacturer who is doing a group buy on vernier and crank pulleys and what ever other pulleys you want.
Just thought it might be of interest as there is a 36-1 tooth pattern on there which would be handy for engine management upgrades.
I recon he could copy the Cossie management conversion stuff in really high quality looking at the stuff he does which would mean that all these half baked kits that are around with bodged on bolts would be a thing of the past and the cars may actually run better having the pointers exactly in the right spot...
If anyone has a decent cossie management conversion kit for the crank, it would be worth asking him to replicate it in his high quality workmanship....
Just been thinking, thats all....
