Thanks for the info. The set-up is 7.8-1 comp. 1.8l, 8v turbo motor....vw block and head. The turbo flows abour 550cfm.....it's an old t-4 that was rebuilt by Charlie (CRM). I am running 12psi right now. The cam has a duration of 226/225 intake/exhaust at .050" and a lift of .440" The lobe center is 110. The stock cam numbers are 214 .400" 110

I will try the above aftermarket cam and see what happens.
