| Regarding methods of maintaining boost between shifts, I recently came
|across an option that is a bit more practical than the fuel into the
|exaust idea. In an article about the Quattro in the Jan/Feb isuue of
|Grassroots motorsports Jim Pettengill writes: for pikes peak in 1987"the
|sport had been tweaked to more than 700 horsepower, had even larger
|wings AND A COMPRESSED-AIR SYSTEM to prevent turbo impellor stall during
| This seems like a good solution for street applications. An air tank
|could be mounted in the trunk which could be easily refilled at any
|service station. A solenoid could be used from a nitrous oxide kit which
|woul be triggered from a closed-throttle switch. The only problem would
|be perhaps a confused reading at the 02 sensor and possible problems with
|the cat. But I'm not sure how the additional air would affect these. The
|compressed air would probably help cool the turbo a little. Its surely
|easier on the turbo than would the little "backfires" caused by injecting
|fuel. Done correctly it would shurely be more effective than bypass valve.
| Just thought this was interesting. Feedback?.
Couldn't you use compressed CO2, that would avoid the problem of affecting
the O2 sensor. Or have I really missed the boat here? Would there be a down
side to using CO2, storage? sensor effects?
