Long 5th gear ratio - is it worth it?
« on: 28 September 2021, 11:26 »
Morning,

As the title says... the box I've bought to cannibalise has a way longer 5th,
the calculator says it'll drop the rpm by nearly 500rpm in top.  I'm not looking for top speed, just economy,
and a chance not to go deaf, 300 miles to Cornwall at 4000 rpm with a 2.5 jetex exhaust is tiring at best!

Opinions please.   :smiley:

Cheers

Mark

Is there a down-side? Seems like a good idea :)
