filter or plenum for TB's
morning all,
i was just looking at the pipercross website and came accross this Pipercross
linky,
so i started to think a bit (very dangerous) is it better to have a plenum type intake or to have an open filter over throttle bodies?

Plenum is much much better for noise. It'll also make it a bit easier to route cold air in instead of just sucking up everything around an open
filter. It could be a bit more restrictive than just a filter, but then a badly thought out filter (i.e. too close to trumpet ends, or using filter
socks) can be pretty bad as well.
Only trouble is that Pipercross one is horrendously expensive. I want one, but for less than half that. Going to have to have a stab at making one
myself I think. Quite a few people have made one up out of ally.

Depends on what you mean by "better" i guess. I will use on of these as in my Tiger B6 i wont stand a chance with the standard airbox and
unless i am very lucky with the height of my planned ZX10R engine i am going to have the filter or airbox sticking out of the bonnet. With a sausage
filter there will be a lot of induction noise so trackday noise restrictions will be an issue (as will the new lower limit for IVA when that is
brought in).
Maybe the airbox will restrict power slightly, but then again so would a restrictive exhaust can if i had to reduce noise that way. I'd be
interested on thoughts about this myself.

I fitted the PX600 to mine a few weeks back. No noticable loss of powa yet. But is is definately quieter and easier to get the air from where you
want it.

Think Triton makes a grp plenum for sensible money.

If you plan to run a ZX12R or toyota 20v 4age engine don't fit the piperx box, they implode on those and might aswell do on others.
