I have the conversion with the .8 module gears. Before this I was realizing that the car seemed to hit a brick wall about 2/3 down the track, cuz you could here the engine winding out. Where I race has about a 270ft+ straigt-away. My final drive-ratio dropped from 5.15 to 4.04, and with my modded MT-12Turbo I have revved the engine and clocked it (using the venom gauge) to about 71 mph. I generally like to run my Evo (w/ Lola) with 1/8 scales, and I must say by the end of the straight I'm with in 1-1/2 to 2 car lengths of the big boys. The key to using this is the Correct-Set-up. Meaning the right pipe, clutch-setting (both) and engine tuning to accomodate the reduction in low-end and shift-point punch. I will say the conversion is not for small touring car technical tracks.
