- High quality natural aluminum finish
Our Tuner Series underdrive crank pulleys provide
power gains across the entire RPM range. Power gains are obtained from
the weight loss. An average of 2.7 HP is gained from every pound lost
off the crank shaft. 85% of our gains are from weight loss.
Additional power gains can be seen from the underdriving of all the
accessories (which accounts for about 15% additional gain). However,
we do not push underdriving for two main reasons. First, it is
important to keep charging systems, air conditioning, power steering,
and water pumps moving fast enough for every day driving. Second, not
much horsepower is gained from extreme underdriving.
An important point, at this price conscious level, is that critical
tolerances on these parts are held to .001�. This is something never
before seen in this price range. |
