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.
