on BW about larger bore throttle bodies...

[Gerard <gerard@poboxes.com>]

Hi!

I see someone is thinking of increasing the bore of their Coupe GT's
throttle body and have a few questions to ask about fitting larger
inlets.

	If one fits a larger throttle body in place of the stock
	unit, will one have to adjust ignition/valve timing to
	cope with the increase air input? I mean in a ECU controlled
	car like the 200t (MAC11-based MAC13A ECU) will one need to
	adjust the timing values in the timing tables or is there no
	need for that at all? What other mods/adjustments will be
	*required* when increasing the intake bore?

	What performance increases can be expected when fitting a
	larger TB to a 10V I5 200t motor?

I need to occupy an idle mind while waiting for some parts suppliers
to get back to me. :)

Thanks.

G.
