Last night I measured the assembled height of my 2V Funnelweb manifold, 750 Holley, 1 3/4" drop air filter housing with a 3" Filter. Total height less gaskets was 315mm.

I then placed some cardboard on top of the airfilter of the motor currently residing in the XB. The top of the cardboard was at the same height as where the top of the Funnelweb assembly will be. I closed the bonnet and then reopened it. The cardboard had been crushed by around 10mm.

Joy of Joys!

Time to take that funnelweb to a machine shop and get 15mm milled off the plennum...

Bugger that! Time to take to your hood with an angle grinder

one of my worries too. If you can't get it under the bonnet, the problem then is finding a scoop that doesn't look wanky .. which is near impossible these days

I will not put a bonnet scoop on it. A XB GS Coupe with a vinyl roof will not look good with a scoop.

I could try a 2" filter and K&N Extreme Filter top. This will give me an extra inch and hence some clearance.

Milling the manifold will remove the 'clover leaf'. Undesirable but perhaps necesary.

Were the XY engine mounts lower than the XA-XE mounts? This could give exhaust clearance issues.

Go for that set up. I know it works because my bro has this set up in his XB. It's not ideal....but almost. The extreme top does a good job of compensating for the smaller height filter. DO NOT MILL the manifold as it has been suggested that you can lose HP.

This way you can have your cake and eat it as well..............

I don't blame you about the scoop. The only issue is if there is no way of lowering the carby enough then something has to give and aircleaners through the bonnet may look good but they are not roadworthy .. but it depends on whether that bothers you or not I spose.
ESP's brother's car run's 12.5s or thereabouts so that option can't be too shabby

Hypothetically - If I had to have a scoop I would use a fibreglass bonnet in the Bathurst XC style.

The Xtreme top gives the equivalent of an extra 1" of filter height, so it'll be about the same as the 3" filter... however, you could have a equivalent to a 4" filter if you milled it... I wonder what the trade off would work out like ie 15mm shorter plennum vs 30% more filter area?

Forgot to ask, how tall is a Funnelweb?
