EAS | ESS VT2-500 Supercharger Build - E46 M3

Another VT2-500 build about to start @ EAS



Baseline dyno happening now, more to come soon.

Fresh off the vehicle transporter, we didn't waste any time. After a thorough go-over underneath the hood and vehicle scan, we strapped her to the dyno to get our baseline:



Pre-installed Modifications

Results


Now that our baseline has been recorded, a backup will be read from the DME and sent off to ESS for tuning. Within hours, we should have our new F/I file, ready to load after the VT2-500 system has been installed.

Installation has begun:


More to come.

M3 is on the dyno now, more to report shortly.

During the installation, we noticed that 2 of the 6 coils were badly corroded - recommending new coils/spark plugs as an extra precaution. Maintenance is key.

After the install was completed, we gave her a quick wash and strapped down on the dyno:

CSL SMG Transmission software was also flashed as an added bonus.

It's been raining here in SoCal for the past week, which explains the 70% humidity figure. Boost is not reaching full potential (should be 7.5lb), so more power is at tap. We may be switching the pulley for a slightly smaller version as per ESS's recommendation to get slightly higher numbers after adaptation.

ESS has simply been more than supportive through the entire installation, even after hours. This IMHO, speaks volumes for the systems.
