|Curious whether my Unorthodox Racing
underdrive pulley (UDP)
from my 1999 Maxima SE would fit the 2002 Maxima, I arranged another
appointment with Unorthodox to test fit the pulley to the new VQ35
motor. The staff at Unorthodox were very interested in the test fit
as well and were nice enough not to charge me anything for the install
or the "before" dyno testing which was performed on the stock
||Steps to remove the stock pulley and replace it with the Unorthodox
pulley are straightforward. The procedure is the same as the one
followed for the UDP
on my 1999 Maxima. This photo shows the stock pulley removed.
||It was discovered that the serpentine belt (K060408) used for the VQ30
install fit the VQ35 fine, but the power steering belt was a little bit
too small, so we replaced it with a Gates K040300.
||The only modification required on the Unorthodox Pulley for it to fit
the VQ35 was the removal of the timing ring. (Nissan removed the
timing ring on the stock pulley as well). Performance gains will
be measured again on the dynojet several weeks after the install.
Check here for results!
||Here are the Dynojet results after the UDP install, superimposed over
the stock graph, Run #1:
|Max Power = 208.8 (Increase of 4.45%)|
|Max Torque=228.4 (Increase of 4.82%)|
