• Direct 1/4 mile comparison between ESS VT1-535 and ESS VT2-625 E9X M3 S65 V8 supercharger kits

      Finally we have a direct dragstrip comparison between the ESS VT1-535 and ESS VT2-625 supercharger kits. The 535 kit runs less boost and is not intercooled like the VT2-625. The VT1-535 M3 belongs to BimmerBoost member LostMarine who is running higher boost thanks to a smaller pulley which is not included in the standard kit and meth injection.

      The difference between the two is 3 miles per hour and 3/10's of a second in the 1/4. Definitely a difference, but not all that large. The more affordable VT1-535 kit shows it is a great bang for the buck option. This is also the fastest record VT1-535 kit 1/4 mile time.

      Both cars are DCT, slip is below.

        This works both ways 1) that tool the older fella had shows exact conditions in the spot u Stand in.2) Atco gets DA from a weather station 7 miles away which is not accurate but everyone refers to and so does Drag times .Now the way I look at it , I would rather use the tool especially if I'm trying to better my times.

        only if you have an agenda you mean.

        unless that tool is at every event , then it will never be accurate and repeatable. so you would have to have a long history of that tool and Dragtimes calc to offset your results.

        especially f your claiming to make more power in worse conditions, when your margin of error/variable w/ the kestrel and dragtimes DA calc is as large as the difference between the record and that specific day using DT DA calc

        you have to keep some constants when comparing....i gotta agree with LM.
