[QUOTE="kozumasbullitt, post: 14238045, member: 25387"] Simple, there are variables from car to car and it is not like you are using two consecutive cars off the same assembly line for comparison (even the same car will have variables that alter data). These comparisons are like comparing track numbers from two different tracks, they are both 1/4 mile in length why should we not accept the data as absolute? The best way to collect data and produce a valid argument is to use a large number of subjects for comparison and use the average value or better yet a mode value from each blower for your data. PS- This is what BPS did when they did testing... this is the initial results from testing all runs at a local dyno shop, he is using a mustang dyno, great dyno but his, for some reason gives very low number even compared with other mustang dynos, same car on another local mustang dyno usually gets 10% better numbers i didn`t care much about numbers, what i am looking for is comparison beetween blowers the car used is a 2012 GT500 that already has a VMP TVS installed with a mild street tune first run is with the VMP TVS but we swapped the pulley and are using the same 2.67 pulley as the stock 13 TVS RWHP 562 RWTQ 562 second run is with a completely stock 13 TVS , stock 2.67 pulley RWHP 561 RWTQ 572 third run is with a ported 13 TVS, stock 2.67 pulley RWHP 572 RWTQ 577 all runs were done in the same condition (temps , iats ,barometric pressure were monitored to reduce the effect on the numbers) , we were swapping blowers on the dyno all testing was done within 2 hours [/QUOTE]
