Cold air box???
pewe - 3/7/13 at 11:11 AM

On the "other" car I'm fabricating a cold air box.
Basically it's a s/c Eunos (read MX5 or hairdresser's car).
The s/c and oblong air filter (four sides foam plus solid metal end plate) are hot side i.e. outboard of the exhaust manifold.
The way it's mounted it currently only has three sides open (s/c was fitted by Moss Europe so I assume they knew what they were doing).
The incoming air will be drawn from behind the headlight rather than the engine bay in general.
Space only allows about 15mm on two of the available filter sides between the filter element and the proposed shield with the third completely open.
Given it's knocking out 160bhp I'm concerned the reduced space on two sides will affect its breathing.
Any suggestions/ideas?
Thanks, Pewe10

measure the air pressure in the box and see if it drops below ambient.

Matt, I get your line of thinking but not being a techie presumably that needs to be done at full throttle?
No doubt some cunning Maplins device will tell me?

Peteff vv that's a totally unnecessary comment -
funny but totally unnecessary.
