I took my 93 sc to have it dynoed a few months ago. With the mods that i had i expected higher numbers. Later i emailed a guy that had his posted on SCCOA and asked him what weight he put down for his car when he had it dynoed, he said he didnt. Later i found out that their are two diferent types of rear wheel dynos. Which one is more acurate? I would think the one that needs the weight of the car to acuratly load the wheel that the car is on would better. Like to hear what you guys think.
