[QUOTE="FJohnny, post: 16749573, member: 191643"] I have the FRPP/Whipple 624 hp kit on a 2014 GT. It came with the 3.375 upper and was supposed to make 9 psi with that pulley. (@ sea level) I'm over 2100 ft elevation here and lost a couple psi of boost. To make it up I swapped to the 3.125 dia. and now make around 9 max in cold air. The pulley direct from Whipple was a slightly different offset from the one supplied with the FRPP kit. That shredded a belt. Called Whipple and they knew exactly what I was talking about. They sent me the proper shim to align the pulley. So, if it's the same kit I have definitely check pulley alignment if you change sizes. [/QUOTE]
