Guy's
i have been racing rc boats for 15 years and have just got into the on road
car scene,
in rc boats i hold Australian speed records, 2 lap oval record and hold Australia's fastest race time to date.
i have played with modifying engine's for many years now,
and that is 1 of my biggest part's of my business, engine mods,
there is always some gain to be made in any engine,
engine timings, compresion ratio's, flow, etc...

fuel= horsepower, there is alot more power to be made in the car engine's,
BUT fuel consumption is also a big thing..

will be doing some mods to my novarossi 21's very soon
will let you no how they go....
