Message	if you look at the 2 dynos below - It appears that the Z was making more power but I believe that Specialty Z let out of it do to safety. If I remember correctly, Seb told me that i was running out of fuel with the dual walbro setup - which is rated at 1000hp (500 each) at the motor. Seb also stated that if I had a better fuel setup i can run higher boost as the turbos were not maxed !!! I was trending towards 850rwhp ( now my border 850cc and stock rods are the limiting factor :) it looks like a few things might be going on here : 1) slightly higher boost 2) loss of tach signal 3) potential wheel slippage on the dyno ? MPH RPM this is not my Z -- but on the last day of tuning we had a few high rwhp Zs and this was a common occurrence :) why does my head look unusually small compared to my body ..LOL ?? still my core question stands -- how come the rwhp and torque changes when I change the x-axis metric w/the same correction factor? I don't understand this 1. =============Sig begins here================ The Devils Z.com 800 rwhp dyno View Me! Disclaimer : Not Safe For Work ! Kid :" Those old guys drive that way ?" Witness : "Yeah, I rode behind them at ZNationals 2010 on these back roads leaving the track day and they were foot in. They ran into the curves w/no brakes and didn't lift!" - Hampton Inn parking lot at ZNationals 2011 -
