My New Experiment...

Skifledanabit · September 12, 2011, 11:09:57 PM

Yep, there\'s even a hole through the bonnet... all I need to do is find a waterproof air filter (i\'m thinking pipercross foam filter) and cut a hole in the top of the airbox and mesh it, may need to drill some drain holes in the sides too.

question is, does anyone have a better idea of a waterproof/resistant filter?

I think itg are supposed to be good?

My opinion is it would look better on the headlight, good fabrication work though

I like the idea. I\'d toyed with it myself a while back. The only difference I was thinking of was not to cut the bonnet bit out. I was gonna cut it on 3 edges under the scoop and fold it down into the filter box. That way any water should go over/around the filter that sits under the fold. Does that make sense? Its still early!
Good work that man, keep us updated with results.

Yeah, it makes sense, but I would have thought that would defeat the object of direct air flow, I\'ve left about 30-40mm on both front and back edges of the hole and folded those down to help with air and (hopefully) water flow, but I\'m thinking the foam filter with the gunk motoX riders stick on theirs to catch all that dirt should do it well enough as long as I keep on top of maintaining it.

True, But I think I\'d still rather it was shielded slightly myself. Thats just personal prefferance though, plus I\'m lazy so I\'d soon get bored of cleaning the filter!
Like I said up there ^^^ though keep us updated with your findings. Do you have an inlet air temp reading for before and after?

Nope, just gonna mash the throttle and see what it feels like lol

TiddlesRX7 · September 13, 2011, 11:24:15 AM

Now thats my kinda test!

Skifledanabit · September 13, 2011, 01:02:01 PM

Lol, yeah, if you hear that my engine blows up, then it\'ll be safe to say it didn\'t work lol

I would definatly put a shield over the relays etc where that intake will dump water onto, I was thinking about doing this and then sectioning off part of the under bonnet to make a cold air box, im just staying with the headlight vent for the time being though. Might just run the turbo out the bonnet :rollin

Also, have you checked that will pass an MOT? It probably won\'t:

The body and vehicle structure
Is free from excessive corrosion or damage in specific areas and there are no sharp edges likely to cause injury.

Yup, it will, ran it by my MOT tester, he says it\'s fine as the vent doesn\'t have any extruding sharp edges, the vent edges have been folded over to ensure that

Awesome, I had to check if my FD rims were ok as they were about 2mms wider than the arches lol don\'t want any excuse for a fail lol I guess turbo compressors are rounded, should be ok to run that out the bonnet :rolleyes:

there is no stipulation in the mot regulations for wheels to be covered by arches but it is illegal and you can be charged by the police

wolfie1 · September 15, 2011, 10:14:17 PM

sharp edges only refer to the sides of a car when a pedestrian could brush up against it and get injured

The tyres do, the wheels don\'t, the arches have to cover the area of the tyre that has tread, something about spray suppression.

The sharp edge rule is also why cars no longer have popup lights and why cars are now much higher at the front due to this (the popup lights allow for the lights to be at the legal height when in use)

wolfie1 · September 15, 2011, 10:24:56 PM

no they dont, thats my job! for example quite a lot of kit cars on full lock foul the suspension arms to get over this problem you remove the wheel arch and its a pass
