Sarnia,
so i recently aquired a 2.3L slowboy stroker motor and installed a t67 "big kahuna" . im running 650 cc FIC and a tial 38mm wastegate. i am also running a turbosmart MBC.
My problem is this. when i get on the car, the mixture is correct, everything seems fine boost gauge seems steady on 11 psi where i set it. but when i look through my log on the dsm link, i have a boost spike to 25 psi for a half a second or so and im showing 1.0 degree knock, i am fairly new to datalogging with the link, mind you, the car was professionally tuned recently. i just want to know if this spike is curable, any suggestions possibly a bigger wastegate?
i really dont want to run much more boost right now because i am trying to familiarize myself with this setup before pushing it... thanks.
