turbo theories Part ???
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?.
