To supercharger e46 M3 or not

[GranticusR]

Looking for more power out of my track day M3
Power for pounds is a supercharger route but heard they can be a nightmare to setup and run hot
Anyone one here that run a supercharger M3

Speak to Simpson motorsport. They do loads of these conversions with excellent results apparently. They use the ESS kits and have been doing for ages.

I ran an ESS VT1-455 kit on my '06 and it ran very well. This was the non-intercooled setup so it would definitely have suffered on the track, but with an intercooler and a vented hood to lower underhood temps, they are quite reliable.

ESS is a bit known for conservative tunes, so several guys on M3F increased pulley size and had Evolve do the tunes for some very impressive gains.

Been looking at VF engineering stage 2 which use a watercooled intercooler i would run mafless so would look at evolve todo the mapping
