That sounds more promising

[Mr.G3]

Noone really addresses the real question: Is there any s/c or turbo out there for the e46 M3 that will work at the track, period (i.e. independently of track/air temp, humidity conditions, and lap times) and has adequate proof - interestingly enough, I don't see the actual vendors chiming in.

[Jean@ActiveAutowerke]

Our kits have seen a pretty good amount of track time. ~20 min sessions at a time if i remember correctly.

However the necessary cooling precautions should be taken when going to the track even on a stock car.

The front air to air intercooler is one of the reasons our kits perform on the track. Cold air at all times.

I know of a few who are vocal on message boards, such as:
MattQ- E46 only i think
mm28
Taza
Saintly- AUS

There are also a few more who i know about but are not on forums.

So what additional mods do you think are needed to not have heat issues with your kit for 20-30 min sessions?

I've never needed anything beyond stock, even when my car had 2 drivers so it was doing an hour straight sometimes.

We highly recommend:
Thermostat upgrade
Sport Fan Clutch upgrade
Radiator upgrade
Running water injection and now Meth


These things make a big difference. Granted every car will suffer some heat soak.

ESS builds their kits to be used under track conditions. Even the VT which does not use a IC performs with no issues on the track. Here is an owners review of a track day http://forum.e46fanatics.com/showthr...ghlight=ess+vt

The CFR kit was tested and built with track use in mind. If you contact ESS directly they will tell you the product is supposed to be used at the track. Most of the long term testing of the CFR was done on the Nurburgring and the autobahn at extreme speeds for extended periods. When I was reviewing the design of my CFR kit with AJ most of the discussion on why they did or did not do something revolved around how it would perform under track day conditions.

All FI products should be built and tested for track use considering that is where the owners can really test the true performance of the product.

I had the impression tazaa and saintly were mainly 1/4 mile track and drag-racing folks- technically a track, but not the full course we are discussing here- correct me if I'm wrong. I don't know the rest of the folks.

Thats good to know- and I am aware of ESS testing the kits at the "Ring" - I don't know if I can take that e46fanatics review though as a substitute for real test data, as it simply shows a relatively novice level driver having fun with his new s/c vert.... I think folks here are looking for real track testing proven data that shows the kits are as ready as they can be for the abuse at the track. If ESS or any vendor can share more high-level (not any trade or product secrets) documentation/data on why they perform at the track, it would help. Would ESS or any vendor backup the driver up for damages done due to a supercharger failure at the track?

knowing more about the track testing is key for me as well. i'd have to be able to run the piss outta the car for 30 minutes in order to buy a supercharger kit

Saintly actually does a lot of road course and i know MattQ does. So did Taza.

[mpegripper]

vf have any comments on their kits running on the track for 20-30 minutes at a time?
