Rich,

Any dyno can read ANY number based on the inputs of the operator. This is why I always have a hard time hearing these numbers thrown out there. We have always talked with Dodge about the dyno and the "way" they conduct the test. Our numbers at the wheels are always very close to what they are seeing and we have used the exact computations on every car we have done so the numbers stay consistent.

Now I will not profess to be a Dyno "expert" by any means, I am just regurgitating what I have learned over the years. When the Dynojet came to the market and gained popularity the numbers shown at the wheels were always much higher than other (load bearing) dynos. I feel this and cost are why they have been so widely accepted as fact. Since we have run our cars on both and the crank numbers are the same for the most part (on an Eddy current Dynojet) the only difference is how they calculate the rear wheel hp. We do not care about making a great number for us or our customer, just consistent repeatable ones that translate to the crank hp really measured.

We have done well over 100 S/C cars and can show all the dyno sheets and a variance of less than 35 hp on brand new and used cars with just a cat back added to the S/C. Most of these variations are because of the year the car was or how many miles are on them. Our numbers are "usually between 585-615 at the wheels on our dyno. We have seen 1 car hit 639 but I think he spiked the tank before he dropped it off ;-)
