Jason's GSR build
Jason's dyno. 234.3whp 157tq.
Tuned yesterday at Locash Racing. Unfortunately, cam timing changes didn't get to be finished because Joe's laptop died. I feel another 4-5 WHP and TQ could have been made.
Notes: we dropped compression to 12.5/1 with a thicker head gasket. Aluminum rods can strech under deceleration conditions and this was done as a preventative manner to ensure the life of this engine at the track. When the owner feels comfortable with his driving skill, then we will remove the extra amount and re-tune.
Also... this Bisimoto crank is a GSR 87.5mm stroke. We were evasive about it at first because everyone would have had their doubts about the build. The numbers speak for themselves.
