Z32 Inlet Pipe Change

A few weeks back Mr. John G. from AZ brought his red Z in for some inlet pipe (ASH) dyno comparison among a few other cooling mods.

OK, I want to make this clear!  Please ready carefully and pay attention.  I know the public school system has failed many of the young Z owners.  The RED run was John’s previous best BEFORE the inlet pipes.  This dyno\tune was performed earlier this year.  The inlet pipe dynos are both the BLUE and GREEN runs.  The reason I am showing two runs is that you will notice the top end power is lower on the GREEN run.  The GREEN run I performed with the VTC system ON throughout the ENTIRE RPM range.  I was doing testing for those curious.  The BLUE run was normal but it showed lower power down low and I did NOT want to misrepresent have people think the pipes lost low end power.  You can see that on the GREEN run the low end power is on the par with the OLD RED run.  Hopefully this did not confuse anyone.   Any-who, no changes were made to the tune or boost settings for the sake of keeping things consistent and repeatable.  Between 3800 and 5500 RPMs we saw nice gains which anyone who drives there Z in the street can appreciate.  At 4700 RPMs we gained a sweet 50 ft\lbs of torque!  Horsepower was in the 40-50 whp gain.  This is on 91 octane fuel and Sport 530 Turbos.  Any questions please shoot Greg or myself an e-mail.  Pipes are available through our site here.
