Our friends over at J&T Automotive and Performance brought this beautiful CTS-V coupe over for us to work with.
We were all very impressed with the numbers for such a simple combination.
This one recieved the J&T LSA top end package which includes in house ported & rebuilt cylinder heads, supporting BTR PDS camshaft, upper and lower pulley, and a set of ID1300s.
Final numbers were 661 HP and 635 TQ on pump 93
Once the auxiliary pump and a more aggressive pulley combo is installed, this until will be back on the rollers with E85 in the tank to see if we can find 700.
