Here is a video from teammate Bill A doing a street test with our smart water/meth system and custom tune to 14 PSI of boost with his 2002 C5 A4 with TVS1900 supercharger

Bill street test using water/meth

Bill states

Rolling into the throttle in 3rd, careful to not let it down shift to 3rd.
Rolling from 75 to 100mph in an A4 3rd with a 2.73 rear end.
First pass at the track was 10.9 @ 128.

Care does have headers, and GT2-3 cam. 243 heads.
the advantage of the TVS1900 blower over the 112 blower is significant.

1. quiet to the point that you cant hear it.
2. worth an easy 10% more flow at equal RPM
3. significant increase in efficiency, more flow less heat.

The MT 305 drag radials offer limited Traction with this amount of torque.

I'm thinking of swamping out 1st and 2nd gear for a 12% reduction to have more speed and let 2nd-3rd shift at 115mph from currently 102mph. This should increase fuel economy in town and shave 2 tenths off the 1/4.
This planetary is $1150, ouch!

Bill ported the water/meth so that there is a nozzle for each cylinder.

Test results was before adjusting for installing 60 lb/hr injectors and bringing boost up to 14 PSI
