[QUOTE="Denver_SVT, post: 16184741, member: 72321"] With VMP 2.49" supercharger pulley and 90mm Idler pulley the car pushed with 7-8 pounds of boost and when it get wormed it pushed only 6 psi which is an indication of belt slip because we noticed that from the boost gauge and Load reading from the datalog as it went from 1.4 load and dropped to 1.280 . The air flow #/min 38,000 We ordered the smaller belt than the stock roush belt within 0.197 inch differences (Old belt size 132..638" and new belt size 132.441" ) and hopefully it will fix the slippage. we tuned it at the street and we will take it to the dyno once we replace the belt. we give the car 15 degrees of timing. we have a snow performance methanol installed that we will turn it on at the dyno to give the car extra 2 degrees of timing. I will post the dyno numbers soon. [/QUOTE]
