GB: Coilpack cover machining (RB26)

[frankiman]

Dammit Frank, wait a month and I'll have mine! :P Definitely an awesome idea! I'll send mine to you when I get it!

why a month?!

how can you not have access to your cover within a month?

[frankiman]

What would it cost to add an extra hole? I like the design but I would like to add an extra hole in the front of the coil pack cover, lengthwise like so:


I think this could introduce more flow. Intake from the front, and out from the rear holes like your Francois

haven't had time last night to take the cover off, but i looked at it for a long minute and,
based on my Fluid Mecanics engineering class, machining slot at the front of the cover won't actually do anything
since the very front of the cover is lower than the cam cover, air won't follow the downward curvature perfectly, and with only a slot, the low pressure fast moving air won't enter the high pressure zone under the cover
you would need a scoop to do that, which all the other slots kinda act like because of their angle (mostly the first 2 slots' pitch)

you don't really need a "flow" of air underneath the cover, all you need is to let the hot air escape at will instead of beeing trapped under there,
its not like its a radiator..

trust me, the slots are effective enough, adding a forward slot doesn't justify another +~20$

Ok sir! Iam in either way.

Alberta franc has proposed a good point. Who knows where I can find a used cover? I don't have a 26 one atm

Then get a RB26 already

Frank, how much with shipping to 80123 USA? I'd like to get this for my car, and I have a spare sitting at home.

[cschepp]

I will have a spare soon. I will try and do this as well.

shipping is 23$ to send it back

so 90+23

[frankiman]

deadline is nov 26, i'd like to have all the covers in hand before the 26, to get everything ready (if there is different designs)

[Ricky Ricer]

You will definitely have mine before then. This is an awesome opportunity! My GTR was misfiring so bad from this problem after a few laps on the track.

uuuup

[cschepp]

Funds aren't available at this time. I have to move and unfortunately I need to watch what I spend

[aN4rk1]

Still fighting with what the best/cheapest way to get this to you is.
Hmmm...any ideas??

[frankiman]

just wrap it in 1" of foam, then tape, its like 10-15$ to ship from mississauga by canada post
