370Z JT Journal - Work in Progress

370Z JT

Went to Specialty Z today and had Seb install the NST pulley set. Was interested to see if pullies made a difference at all. The NST thread had dynos, but for a 350Z.

Bought the NST pulley set for a very good price through a vendor WESELLCARPARTS, and pullies were shipped directly by NST in Texas. I was ticked that the pulleys came scratched up and even had a small chip. Talked to Seb@SZ and Mike@NST, and both said it will not affect the Z. So whatever, I went through with the install.



There was a blip at 6.5K RPM which gave a false reading of TRQ, so please disregard the Peak Torque number (blue line).

Solid gains were made from 4.2K RPM, all the way to redline. AVG gains were about 6 whp/6wtq. At 6.2K RPM, and 7.1K RPM, gains were about 10whp/10wtq. Peak gain of +6 WHP and about +1 WTRQ.

Car seems to rev up easier. Besides that, can't really feel the small bump in power. I will see if my MPG imroves at all. All in all, for the money spent ($400 installed), not too bad.
