Do you really need less nitro if you run with a tuned pipe?

[OldSchool]

I remember reading somewhere that tuned pipes are designed to run on
low or no-nitro fuels. If this is true, it could be a money saver.
Has anyone else heard this? Found this to be accurate?

Thanks!

It's a bit arse about face, the pipes aren't designed to run with (or
without) a specific type of fuel, but a specific type of ENGINE.

Engines in Europe have historically been high compression engines which
don't need nitro (and in fact don't LIKE nitro) but they DO need a tuned
pipe if power is high on the list of "must have's".

Japanes engines are usually LOW compression engines, designed to run on high
nitro content fuel (compared to European/FAI fuels) but they still benefit
from the use of a tuned pipe. They benefit more from the pipes with some
internal mods though (like raising compression ratios slightly) so it's not
always a case of "fit a pipe and sit back to watch the fireworks"

Best combination going is the Rossi 60, a Rossi pipe and manifold, tuned to
the right length for your helicopter. Piece of piss to use, and cheap as
chips to buy and run.
