E9X M3: SuperCharger Owners List ///

wow thats so great

Add me to the list! AA stage 2 being installed now; better late than never to the party.

Hey Guys,

I have a 2009 e92 m3 with full bolt ons and I am looking to get a supercharger kit but don't know exactly which one to get. Trying to decided between a ESS VT2-650, a G1+ kit, a G2 kit, or an Active Autowerke Generation 2 Level 3 kit. (Are VF supercharger kits even worth considering? I Don't know much about them.)

Is the VT2-650 really worth the extra $3000 for just 25 more hp? I assume the 650 is much better at cooling and whatnot vs the 625 which would be perfect for me. I track my car regularly and need good cooling, will the VT2-625 or 650 provide enough cooling for a long hot track day?

Anybody have recommendations or experience with these non VT2 kits? I might go for a methanol kit but I'm not sure if the extra power is worth the increased wear and tear on the car. Plus I would still like to daily drive it in the summer, Will supercharging it with a G1+ or G2 or AA Gen 2 Lvl 3 Kit make it a pain in the ass to daily drive? I have heard from others with ESS 625 kits say they still daily their cars regularly.

Any input, experiences, recommendations and thoughts are much appreciated!

Thanks,
Derek

Got one of the last Harrop SC's for my garage queen and so far very happy with it. Had a few minor issues with install but once sorted she is really putting it down. Still need some fine tuning but getting there! And that whine....

Nice, tbuck. I clocked you at 4.82 seconds on that 0-60.

Reporting in - a couple weeks into ownership of my Harrop on the e93 platform. factory air box, test pipes. As others have described, it gives the e9x m3 sportbike-like maneuverability on the freeway.

Having used Harrop installed via DrFerry by Performance Technic and SW support from Mike @BPM

Honestly, not going well started on 10-26-2022 and still there today, fighting a breakup between 5-6K rpm and boost pegs at 4psi. Will make a post in official thread today.

AA stage 2

ESS G1

Please add me to the list 2008 M3 supercharged Active Auto Works with meth.

2009 m3 with ESS 650 VT2. had it installed and running on the car for 10,000 miles. Please add me on the list

Hi all. Can you please tell me what is the measurement of the air filter that comes with the G1+ kit please? Im trying to purchase a Drycharger Air Filter Wrap from K&N and needed the size. Any help would be appreciated. thanks

ESS VT2 650. Had it on my 2008 E93 before totaled it in 2017. Removed and installed on 2011 E93. Still running.

Didn’t realize I had missed this thread. 2011 with an ESS 625 kit. Roughly 90k miles on the charger and 179k total on the M3. Enjoying every day with it!

Does anyone know the part number for the slightly shorter belt people run on the ESS G1 if they're experiencing minor belt slip?

Edit: Belt Part #6PK2110

high mileage ESS-595 kit update...

160,000kms / 100,000 miles on the ESS kit. Just did drive belt and replaced the belt drive pullies here: https://esstuning.com/maintenance-upgrade/s85/

also replaced the air filter which actually took a bit to find. AJ at ESS was very helpful with the parts.

doubled mileage to now over 200,000 miles (339,000kms) on the ESS VT2-595 and doing another round of maintenence.

curious if people are changing up pulley sizes or bypass valves for additional 'fun' on these?

Just ordered a new drive belt from ESS.

I occasionally remove the bypass valve hose and run it open to vent, but eventually get tired of the sound and put the hose back on. The car does pull a bit better with the hose removed and a small air filter in place.
