Post by: Janner_Sy on February 12, 2010, 11:41:24 am: found this on SCN. quite impressive. seems like a good viable option for guys with evoms.

I wanted to quieten down the overbaring sound of the intake for daily use. During highway driving it is particularly loud at cruising speeds. The noise, which seems to come through the glovebox and passenger footwell, all comes from the cone (well at least with an EVOMS it does), so that needed to be caged. Some research revealed a useful tutorial from the net on fibreglassing an air filter enclosure. Bought a couple of fibreglass repair kits from the local hardware store for R95 each, paint brushes and masking tape and I was good to go.

Before

The EVOMS partition and pipe (cone removed)

Making a mould of the cavity with masking tape, cardboard and newspaper to protect the car and engine bay from stray resin drops. I decided to make the enclosure two parts to add to the EVOMS partion. A bottom and sides was made first and the lid thereafter.

Moulding the ram air pipe to feed into the enclosure

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00080.jpg&hash=51fc440509aee2760e1b01114ac0d763a9bb2704)

The fibreglass sheets impregnated with resin (mixed with the provided catalyst). Its really great material to work with, once wet with resin it melts to the curves of the mould. Latex gloves come in handy (excuse the pun) when working with fibreglass sheeting and resin

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00086.jpg&hash=11d10d7aa812d6a9306eb6e565f077c70e1fad9a)

The bottom and sides part of the enclosure dry and stripped from the cardboard mould

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00093.jpg&hash=13696a94faa7355d674d789d531f155b2a91dab4)

The bottom and sides of the enclosure installed back into the engine bay

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00096.jpg&hash=b2a52f51a5237417208f0147bec006510bfc6047)

A hole was cut for the ram air pipe to feed into the enclosure

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00098.jpg&hash=9041a86ff76c3c1ef774f8349b4fb87c3fa6f9e3)

The lid was made but profiling some cardboard, sticking it to the sides of the enclosure and then using masking tape to contour the CAI pipe. The resin impregnated fibreglass of the lid

The dried and stripped lid

Using a dremel (pencil grinder type circular cutting tool) I cut off the excess fibreglass similarly to the bottom and sides half.

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00114.jpg&hash=48ce06be048fa88710132ee8243b3acd70301b4b)

Using some more fibreglass (courtesy of my work :D) and resin i made a lip around the edge of the lid

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00116.jpg&hash=159260a9a792c323b07c89ff324c3f3a12b39229)

The first lid was not smooth at all on the top surface and hence I had to take a mould of it and then use that negative to make another lid. The mould for the second lid. Using masking tape on the inside surface to give the smooth finish on the top surface of the lid.

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00182.jpg&hash=06578d19809c6268d9b041b3037a7528e87d5e6f)

The lid mk2 resined up in the mould

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fhubbly_bubbly%2FSeat_Leon_Cupra%2FDSC00183.jpg&hash=fb570aaa75f1e51019e3e4e2d1bacea6e7350e47)

The lid came out the mould looking 100 times better than the first. It still wasn't as smooth as I wanted it to be so i proceeded to coat it with lots of thick coats of paint. This is one of the colours that I used, for all the chrono lovers ;)

The enclosure works beautifully to keep the cone alot quieter. The consistant drone at 3000rpm during highway driving is gone. It hasnt completely silenced it only made it alot easier to live with everyday. When it comes time for dyno days, breakfast runs and drag races ill open up the enclosure to make some EVOMS noise and then close it up again for my week day commutes :) I am planning to do comparitive logs of air flow with the enclosure versus without. Ill post the results as soon as they are complete. It might be the case that the performance is better with the enclosure. In that case ill keep it on for performance events. Mass of air taken in and intake air temperatures should show that up pretty easily.

Sure it does the job though :smiley:

Post by: Janner_Sy on February 12, 2010, 12:05:04 pm: Should keep out all that hot engine air, and create a massive high pressure area around the filter from below the fog light and the front slam panel

^^^^ My thoughts exactly.

Great concept but very amateur execution.. Fine test prototype.. Now go and make one or get one made that looks professional. Not that my efforts would be any better!

I suppose there's not much point in making a lot of effort to test a theory, but it doesn't look that bad. I'll be interested to hear how it performs :happy2:
