Hey Damain could you get the part number for your custom cold air mod?? The black plastic rectangular piece. Thanks

If you're selecting a mesh and want to know how much cross section it takes up ("open area"): surf this website:

I think the oil cooler fins do a good job of making the flow turbulent.

No, If I need to impress people with my vocabulary, I do that at work where clients pay $200+ per hour for them. As for this forum, you pay 4 what u get.

I offered another view and you have to be a ***** about it.

If you're an engineer, you're supposed to look at all aspects and do a cost benefit analysis. Go f*ck a cone like your avatar.

not sure what part ur talking about?

hey hey, calm down you guys, ...this is my thread and i will not have this childish posting goin on....

we are all adults here, ...so stop it right now you big weenie butt heads!!!

DamonB

So you put on your engineer hat and did a cost benefit analysis which determined that blocking most of the oil cooler duct is an improvement?

Do your clients pay for grammar too, or is that extra? I'm glad that you are wildly successful.

Damian,

How are you fastening the undertray to the bumper? (or are you) I found that my GT-C flexes quite a bit so I was thinking of Dzus'ing it together for some rigidity.

Nice work, btw.

A bit off topic here, but why are you running power steering on your track car? It seems like quite a few people on this board prefer manual steering, and I've been considering removing mine. What are your thoughts on this?

You don't shush me. I shush you!!

Shushing now.

I removed my power steering partly to make more room in the engine bay but also because there were several times I "beat" the power steering. I would be making what I thought was a normal turn when suddenly the effort on the steering wheel would change drastically. It also happened in the slalom in the Mazda6 at last year's Mazda Shootout.

I just think manual steering is safer.

Damian how are you mounting it? Could you show pics of where? Maybe for us n00bs that are considerings this?? Ive worked with fiberglass before (repaired a canoe =P) so thats not my deal, just wondering where to attach it. BTW done any high speed runs to see how it holds up?

I'll post pics when i get it finished this weekend, I am using the stock undertray moutning points with metal 'tape' to hold it in place. I'm not talking thin metal tape that you stick on, im talking the thick tape that has holes in it, I drilled some spots in the duct, bolted the metal tape strips on it, then bolted it up to the frame, its solid as a rock. I will be making a full front underpanel this weekend also, it will pass in front of the nose about 2" to act as a front splitter too. Pics will explain all this, I'll post em after I get it all figured out. :-)

I will be at at BIR on the 4th (see my videos, its the one where I hit 160+ in the straight and go through turn 1 at 140), so that will be a great test for the ducting work and underpanel stability. I'll be able to report back after that event.

You took a look at a picture and decided that it was absolutely wrong. Most engineers I work with don't have that absolutist, not-invented here, mentality.

Oh well, in a few years you'll be out of a job anyway when we outsource all the real engineering jobs to India and China.

Alright, cant wait to see it then!

damian, am I still shushed?

I did a good deed and fixed his use of the quote feature in the post too. Doesn't that get me anything?

damian

hahah, ok ur un-shushed :-)

... just as long as you both only talk about ducting and not each other!!!

;-)

DamonB

Thank you. I would just point out to some that it doesn't take a genius to figure that if you partially block a duct intended to supply air to an oil cooler then you only get a partial amount of air flow through the duct. So any un-genius when confronted with a picture illustrating such can rightly determine that it's a poor idea without any further investigation. It's not complicated in this case.

Of course I'm making the supposition that if you're going to stick an oil cooler inside a duct you do in fact intend to have air flow through the cooler. Maybe my suppositions are just all wrong. We may as well not put air in our tires either. You see, if you have air in the tires you might run over a nail and all the air will leak out. If you just leave your tires without air in them then you can safely drive over sharp objects without worrying about your tire going flat because after all, it's already flat.

hehe, you dork :-)

EFS.O

Damian,sorry for "hijacking" your thread but it seems that Damon wants to keep up the flaming.So,thanks Mr.genius for calling me stupid(indirectly).I told you before that i tested the mesh with an air compressor and it worked FINE.Don't forget that these ducts work like a "ram-air" style like in the motorbikes as Kento stated before.In other words,(as you probably know)you will see a change in cooling after some speeding.You really believe that this mesh is gonna stop all that air flow coming at 60+ miles/h?I am not absolete,i agree that it might reduce the flow(5%?) but for me its better that to buy or to repair every now and then the fins(and a damaged fin is the worst thing for the flow.As for the air in the tires,you know,now there are run-flat tires in the market :-)

P.S Ooops,i forgot a 43 posts rookie knows **** about cars....

damian

iTrader: (2)

its cool efs, no worries, i fully understand both sides of the argument, one is dont block the coolers to get best air flow, the other is protect the coolers so that they dont get damaged and cant do their job, the best is a balance between both worlds based on the cars environment.

DamonB

Yes. Not all of it, but much if it. We tend to automatically think of mesh as "nothing" but that's not true. If the mesh has only a 50% void area then it's no different than covering the inlet with a solid panel and putting a single hole in that panel only 50% as large as the inlet. The mesh would probably be even worse because not only have you covered a large portion of the inlet area you create a lot of turbulence in the air as it passes through the fine mesh. This will impede and slow the flow of air down the duct and you will actually get fewer air molecules making their way into the duct because of this. It's much like having a clog in a drain; some of the air behind the mesh will "back up" and never travel down the duct, much less to the oil cooler. The flow of air around the car will take the easiest path and thus if it's too much work to go down the oil cooler duct the air won't; it will just go around the car.

You're certainly going to get some air through the mesh and to the duct. You would certainly get MORE air to the duct if you chose a mesh that had a much larger void area. By handicapping the air flow to the cooler you automatically handicap the cooler in doing its job.

I apologize if my comments offended you. They were in response to someone else's posts.
