The 236HP pull was with only JWT Intake and Tanabe Super Racing Exhaust.
The 242HP pull was with the Kinetix V3 (black plastic) Plenum added.
NOTES: 1) Conditions were not ideal at 90 degrees and humid.
2) Car is daily driven with 45k miles on the odometer. May need tuneup.
3) Car is running rich which is surprising with bolt-ons on the Z.
4) Note a 2ft. lb. TQ loss with the Kinetix Plenum?!
I am planning on going back this weekend to add the Unorthodox Pulley and Test Pipes, then running 2 more pulls. Hopefully will see at least 250-255whp and an increase in the TQ numbers.
Of course headers and ECU reflash will help as well, but those are not going to happen within the next couple months...
