track car radiator ducting project - many pics
well, i did a hack job with aluminum sheets on the track car and though it was time to do a bit better job on the radiator ducting. I had a few weeks down time between track events and decieded to take the nose apart and try some stuff, basically i made a dedicated radiator duct that will replace the stock underpanel, eventually under that will be a full flat underpanel for, but here are the first run of pics on the rad ducting project:
back side of cardboard mockup getting fiberglassed
i just used cardboard to make the ducting mold and fiberglassed right ont he cardboard, making the cardboard become the 'skeleton' of the duct
a shot of it after i got the first layers of fiberglass on it
another shot fully glassed, it was a messy project :-)
i sanded it down but i wasnt too good about making it perfectly smooth
after a first coat of black spray paint
following a suggestion from the master (Noah at speedlabs) I used rubber flaps as the seal to the awkward power-stearing pipes that run in front of the radiator
I used velcro to keep the 'free' side of the rubber flaps in place
a test fit on the car, looking good so far :-)

Nice work Damian.
That actuially looks alot like the one I made for a customer. Stock 93 R1 bumper. Greddy FMIC and KOYO rad. I'll send you some pics of it.
Mine was fabbed out of 18 gauge steel. I am thinking of glassing it. Although I am confused as to how I would connect the uprights. Maybe you could give me an idea when you see mine. If you want to!
Now all you have to do is the air intake ducting!!!
On a side note. A few of the people I showed the scoop to during fabb, just laughed and made fun of the akward looks of my contraption. Well when it lowered his water temps by 25-30 degrees he shut up quickly. Seriously the temps were at 240 sitting in the shop after warm up. Dropped to 180 cruising and only have seen 195 with alot of "spirited" driving. Function over form anyday for me!!
Also what are you going to do for the top side? To keep the air from pushing out the top. I made a full plate for the gap between the Rad. and IC. But I am going to redue it for the whole bumper support area. ( cleaner look)

thanks BigIslandSevens :-)
>>Maybe you could give me an idea when you see mine. If you want to!
well, i attached the sides by using a strip of fiber glass that i layed down on a scrap piece of cardboard and 'painted' the resin on, then i layed it on the moild in the corners and used a foam brush (dipped in resin) to form the fiberglass strip into the courner, i did that a few times on each vertical 'fin' corner and that was that, pretty simple.
>>Now all you have to do is the air intake ducting!!!
well, its already build into this mold, i just dont have the final side wall up, it will make more sence in later pics

Actually Ive been thinking of doing something similair to this for a long time. As a cold air box. I get massive amounts of boxes (cardboard) at my job, just the space time would be the only thing. Cool stuff damain, keep us updated on those temps.

Damian,
Excellent job. I usually look at these threads with an eye towards what is wrong with the mod because so many mods screw up the car. I like the belly pan, I hope it is strong enough to hold up to high speed.
I LOVE the rubber around the PS line and the super duty velcro used to hold it down. That stuff kicks ***!
Great job!

thanks jeff :-)
>>I hope it is strong enough to hold up to high speed
it definetly should hold up, i used a few layers of fiber glass and the cardboard had a corrigated (sp?) center so it added a LOT of strength to it.
more pics to come as i get it further along...

P.S the mesh is fairly large,its just the flash that makes it look small...:-)

One should always use a mesh with a high void ratio. Usually this means an octagonal or square pattern. The larger the voids, the better. Using that style of grill mesh does indeed cut the airflow to more than half of the original. I'd get it off of there asap. If Greece is as hot as it is here in SW Florida, you're just asking for trouble
Kent, any chance you guys are going to get a new MV1000 for a full road test vs. some of the other liter bikes? I liked Alan's writeup but he's an MV owner and therefore biased.

Convective cooling is for people who are trying to impress themselves with vocabulary.
