Need a STOCK LT1 dyno chart for modeling software
I have custom software I wrote years ago that models the acceleration performance of cars, motorcycles, and even buses and motor coaches, and I want to model my 1992 convertible to see what effect a rear axle ratio change, from 2.73 to 3.07 or 3.42, would have.
I need a dyno chart for an LT1-equipped Corvette, one that is "typical" versus particularly strong or weak, in order to do the modeling.
Ideally, the ambient conditions for the dyno run would have been moderate enough that the correction factor ("CF") used, whether SAE or STD, was moderate (i.e. 1% to 3%, not 5%). This is because dyno runs done under ambient conditions that require a 5% or worse correction factor are not trustworthy for technical reasons.
Anyone out there have such a dyno chart? It can be a jpg or tif image, or can be an original Dynojet run file (I can read it via the Dynojet software).

And this:
Note: The RPM's are a bit off, the factory tach is not accurate. He set the dyno to 2K with the tach, the engine was turning less than that. Redline is 5850, I have to shift at 5K indicated on the tach, otherwise I will hit the cut off.
