Andy, what is that based on? Just stock horsepower with the usual 15 percent improvement?


Hey Andy, I know i am digging up an old thread but..
after doing some leg work, and speaking with Jeff about that 235 WHP that was used to class that car, I need to ask for a clarification. Was only one dyno test used?

My discussion with Z1 motorsports, one of the leading Z shops in the country, puts that power of a basic IT build in the 200 hp range at the wheels.


Here is also a link to the 300zxclub website where people put up their dyno numbers with, again basic IT mods. It again supports the 195 - 205 hp at the wheels, numbers.

So how would I go about trying disprove the one dyno sheet (that I know of) that was used to classify the car weight?
