hehehe..bang on John.

GENERAL STATMENT :

As John said earlier, first off what are you trying to achieve?? Better air flow is not the be all and end all of rotary power, you can shove as much air in to the chamber as you want but when you get to a certain stage other things come in to consideration, such as Pulsations from the rotor (as John said), exhaust ports, big timing issues.

And what most people dont consider is that its all well and good having 450,000 Bhp but where does it come in the revs?... and doing all of this stuff will affect the power band on a rotary probably more than everything else!!

By the way i like modding and trying new stuff, just saying that your best off having a goal to achieve or you can end up with a machine that is excellent when your doing 6000rpm, but below that can be a dog.

i would like to use the original FC engine as it was rebuilt at 50000 odd miles and only has around 65000 on the clock?and yes i have looked at other sites such as FC3s.org etc but there were alot of bad attitudes there, ausrotary was good but site was down and everybody seemed quite friendly here

I know ross uses the cosmo uim with the bigger runners but has anyone tried to go bigger?? apart from pp port that is

what size and what happened then, any pics

colin5524 · January 05, 2007, 05:21:22 PM

mostly drag with the hope of a few trips to the mainland for a little track action

stuart wizy · January 05, 2007, 06:58:20 PM

found a few pics for u collin
they seem to be made and used all over the world apart from here in the uk,
The big question is WHY not??
ive got a link somewhere on dimensions and how to make a inlet man and plenum explaining about velocity stacks inside the runners to speed up airflow

Thanks for the pics!
