Gasmaninaseven Posted January 21, 2010 Share Posted January 21, 2010 POBC, Having recently moved to CC Roller Throttle bodies, I'm interested in options for noise reduction, if necessary. The latest R500 models seem to have a new airbox, with intake under the bonnet near the passenger side of the scuttle- already a "busy" area, especially with heater. Higher intake temps too; though the quantitative significance of this I'm not sure. There is no obvious way of ducting air in from the outside. The earlier cars look like they have the carbon airbox from the C400 racecar- I favour this as a simple, and no doubt cheaper, option. Does anybody have any pics of this setup? Which Titan backplate does it use and which airfilter - does it simply fit over the Pipercross filter? Thanks, Neil Build pictures here Guantanamo Bay Orange SUPERLIGHT R400......

nigelpugh Posted January 21, 2010 Share Posted January 21, 2010 Neil, My R500 has the later style intake under the bonnet too, not sure how good it is because of the hot air in the area at intake point. However I am reliably informed it makes the induction noise quieter. I think the box you are referring too is the one below, which was what I ordered with my R500, but CC switch to the other type: C400 Airbox They are not that cheap from CC though, and you need the back plate too.

Gasmaninaseven Posted January 21, 2010 Author Share Posted January 21, 2010 That's the one, perhaps the fixing kit has longer studs and literally sandwiches the filter frame onto the backplate??

Jason Plato Posted January 21, 2010 Share Posted January 21, 2010 I have the earlier version that Nigel linked to. It fits over the std Pipercross filter that comes with the R series, and attaches onto the std backplate - effectivly sandwiching the filer betwen the carbon box and backplate with the use of longer quater turn fasteners. The box significantly reduces noise (havent measured it ) but it does rob a little throttle response. If your coming to Llandow I can bring it for you to try or look at my links below here is my Duratec R .... C7 TOP Taffia AO Link to comment Share on other sites More sharing options...
Gasmaninaseven Posted January 21, 2010 Author Share Posted January 21, 2010 Thanks very much, I've got the picture now. I'll try under "Wanted" just in case somebody or a race team has one kicking about. Neil Build pictures here Guantanamo Bay Orange SUPERLIGHT R400......

Alaskossie Posted January 21, 2010 Share Posted January 21, 2010 I bought the earlier-style airbox for my 2.3 Duratec, and with the extra height of the 2.3 engine, there was some definite interference between the bonnet and the topside Dzus fastener on the airbox. It took a bit of fiddling and a piece of carbon fiber to cut that fastener off and replace with two fasteners to the side and one at the bottom. (I didn't come up with the solution; Nathan Down, formerly of CC and who some of you may know, is helping me finish my car). The standard Pipercross "dome" air filter is a press-fit into the old-style c/f airbox. I am sure that some amount of intake surface area of the filter is lost by being flush up against the airbox. So we tossed the dome filter, and put four individual Pipercross foam intake "socks" on the four trumpets. (I launched an earlier thread on BC on this question of airbox interference with the standard Pipercross air filter, but got no responses).

Gasmaninaseven Posted January 21, 2010 Author Share Posted January 21, 2010 Thanks Alaskossie, interesting point- I'll look into that. Hope you have a heated garage!

Alaskossie Posted January 22, 2010 Share Posted January 22, 2010 Neil, Now that you've asked... It is 0 degrees F. outside right now,and I am just finishing with the construction of a 3500 square foot garage with radiant heating in the floors.... see the thread at: http://www.garagejournal.com/forum/showthread.php?t=41882&highlight=alaskan But my Seven would not wait, and is being built in a garage down in Colorado where it's a bit warmer. Hope to have an article for Low Flying about driving the Seven from Colorado to Alaska next summer... however, I should not count my chickens before they hatch.....
