dont remove your headlight

[CorvallisBMW]

O'rly?

That's nearly perfect then. I removed the fogs from my BMP front bumper so I can install the BMP brake ducts, then the small "what are supposed to be the brake ducts" are now not being used. So I could open up the one on the driver side for it.

Although that does put the pick up close to the ground.

But I don't drive my car in the rain usually, so it shouldn't be a big deal.

water isn't going to travel UP the air tube and in your filter, so you're ok.

Yeah more info please.

I think what he means is that as air travels between the car, it gets slowed down and bundled up (due to viscous (friction) forces- Bernoilli's equation only applies when viscous forces are negligible). This creates a high-pressure area under the car that is higher than ambient pressure, so theoretically if your engine drew its air from there, it would get more mass than, say, behind the headlight because there's more force pushing the air into a hole than there would be if the hole was elsewhere. Before you think too hard about it, though, you'd have to be moving pretty quickly to build up enough total pressure to see a positive effect, and I'd be very concerned about road debris, water, etc.

so you did do the 5spd swap after all?

[der affe]

what about with out the splitter?

[Turf1600]

I've been thinking about doing the same thing and attaching it to one of the brake ducts. Then again, I don't have a cone filter, so I hardly care. However, my dad's car does. KA, do you sell M42 heatshields?

You need to reserve areas of high airflow for deer whistles.

You're front splitter creates a high-pressure area right above it, near the brake cooling ducts. For the maximum airflow, you should attach the hose there.

[z31maniac]

meaning below the bumper?

so you are saying that the air travels around the grille area?

Yeah more info please.

[Edev]

no, I dont steal ideas. i just got annoyed with triclopse E30's

[kamotors]

Hmmm....

You are on a path to re-discover some interesting quirks in the e30 chassis aerodynamics (same for the missing headlamp trick).

I'll give you a hint though: If you really want ram induction... Drop a tube below the boundary layer.

thanks, this is just my alternative to the 3 eyed e30's.

At least this design isn't stolen from someone else...


or is it?
