(im sorry if these arnt bang on im going from memory some may be higher or lower)
These #'s may be a little high but it should be putting out around 320-330hp at the Engine around 260-265+ or so at the wheels… Its not tuned yet. The ECU is going to AAM in the spring and theres also the possibility of some forced induction in the near future.
As for a 1/4 time it hasnt been run yet but assuming i get a decent launch im gunna say a mid 13, because a stock Z will run a 13.9-14.1@101 so i dont think im to far off, But who knows lets take it to the track and find out
