Contour Enthusiasts Group Archives Forums Modifications Forced Induction Need help finding a link ... motion sensor for intercooler sprayer.

I am reaserching the possiblity of getting a Jetta 1.8T and obviously doing modifications. Rather than spending gobs on money on a "race" intercooler, I would rather opt for an intercooler sprayer. I remember back when WorldTour was working on his Vortech with water injection, someone posted a link to a site in Australia I think. The link highlighted a long research topic on hooking up a momentum/motion type sensor to an intercooler sprayer. Anyone remember the site? If so, PLEASE post the link!!!

IIRC, the sensor was used so that the system would/wouldn't spray the intercooler at certain times ... this maximized in-town driving when his intake temps where at their highest.

Nitrous Express recently came out with a CO2 system that has a oval shaped spray bar mounted on the intercooler. You spray the CO2 through orfices in the bar, the CO2 is very cold by nature so it drastically helps cool the intake charge. Fairly trick stuff, and CO2 is relatively inexpensive.

I've been contemplating a 1.8T Beetle, Subaru WRX, or SVT Focus. So far my first choice is the WRX, but not sure if I can afford it. Second choice is the 1.8T Beetle.

This and other systems I am well aware of and intend to investigate further ... I am looking for a specific link that detailed an investigation of a momentum switch that activated the cooling device (insert method here). For example ... siting still with car running, spray every x seconds until the IAT sensor reads xx. The system tapped into IAT sensor IIRC and was "programmable" to a degree ... it's been so long since I have read it I forget. Basic premise was controlling intercooler sprayer for optimized performance without having to hit this button or that button. The "system" had a special momentum/motion switch that detected when the car was stationary and/or running. If the car was running and not moving, heat soak occured and the system would spray the intercooler without any user interaction.

No offense, but Bettle = Girl Car ... Name one guy that would be comfortable putting a flower in that flower holder and I will show you a guy that is VERY in touch with his femanine side

Thanks ... found a link

http://www.audiworld.com/tech/eng22.shtml ... didn't have to look too far, but definetely not the same link, but talks about the same product.

Don't buy the 1.8T Beetle unless you're getting the new Turbo S. The regular 1.8T Beetle makes 150 hp; Turbo S Beetle 180 hp. The Jetta 1.8T makes 180 hp for 2002. To me, it felt that the Jetta handled better than the Turbo S, and I like the fact that you can get the Tiptronic tranny in the Jetta as well. Turbo S Beetle was/is too expensive as well.

I have heard good things about teh Nitrous express kit.....contemplating doing it to my Rex

The auto in the Jetta is a dog, even with the trip-tronic. My GF has a 2002 and that car is pretty quick even with the auto, but the tranny doesnt seem to handle the boost smoothly. Its not even close to an SVT on the curves though.
