TUNED PIPE BASICS
The theory of tuned pipe operation is fairly complex, but the end result is that
they act as superchargers, increasing the engine performance by up to 30% even on sport
engines.
CONSTRUCTION
Prestwich Competition tuned pipes are all constructed from bronze welded,
lightweight stainless steel sheet. The tuned pipe consists of: double coned tuned
pipe section, rear silencing section, watercooling on front cone only with no mixing of
water and exhaust gases, pressure take off pipe for fuel tank pressure. (can be blanked
off if required) .
PERFORMANCE
These tuned pipes have been developed through racing over the past 25 years, to
give the best possible performance with excellent throttling and the lowest possible noise
level. The tuned pipes are watercooled to maintain an even temperature and so give a
consistent performance.( the watercooling is around the header part of the pipe
and water does not mix with the exhaust gases)
Performance is proven by results. In the 1992, 1993, 1994, 1995, 1996, 1997and 1998,99,
2000, 2001,2002
British FSR Championships, almost all the winning boats used PMC tuned pipes. FSR RACING
Champions from France, Germany, Italy, Hong Kong, Poland, South Africa, Holland, Denmark,
Sweden, Belgium, Austria and many other countries use PMC tuned pipes.
Every tuned pipe is complete with comprehensive
instruction leaflet, giving recommended manifold lengths and instructions on adjusting for
best performance.
