40 buck brake duct kit

its a joke man..... :roll:

good excuse :roll:

believe it or not thats just gonna let more air in unless its ducted. Only way to really fix the air in the engine bay is to not let as much in. Either block stuff off or duct incoming air. And/or put a plate under the motor. In club racing you can only have a plate on the front side of the axels.

Don't believe me? Look it up on sportcompact. Unducted holes in the hood only help for dyno's by cooling the engine bay. But in the real world they suck air into the bay and down under the car. All holes should be PROPERLY ducted ;)

seee i got that on lock..... when i bolted my hood down its not all the way lined up at the moment so it has a gap at the back

From what the crazy gnomes tell me, there's also a bunch of high-pressure air in the engine compartment that doesn't flow through too well unless you vent the back of the hood to let it escape up. Confirm/deny?

We used to vent the engine compartment to the brakes with these:



Then seal up the ducts in the air dam...

This was top secret BMW e30 info here: The less openings in the air dam and front of the car, the less parasitic drag.

Yeah but theses ducts arnt pointed directly on the rotors.... When i bleed my brakes this weekend ill take pictures of the ducts positioning

I remember reading another post where the person had some cheap ducts. The un even cooling caused by poor air redirection caused his rotors to crack and prematurely corroded his pads.

well you should add a front lip and is splitter on your car ... so the car will stay planted still i digress.... i just decided to put pics up incase anyone wanted to replicate a ducting kit at the fraction of the cost.

My car doesn't have anything on the front right now. I'm getting a SP1 BMP front bumper ready to go on the car for now. Its replacing the plastic bumper w/ an 87' 325is air dam. Although I'll prob get rid of it in a while. But yes on the track you want your lip/splitter as close to the ground as possible.

business managment.

and once again, I didn't say that having the hoses like that will make your car take off. But adding air under the car is never good. If you don't understand how a wing works then maybe its time to go back a few grades. A sedan will never have downforce, but you want to do all you can to reduce lift.

Excuse me, asubimmer, what was your major while in college? I am thinking communications. That explains why your oral skills are matchless.

im not sure that even on a high speed track that i will do over 150... but there is an e36 m3 over at bimmerforums that has done 160 with a similar setup... so i think the ducting is sound

[Fidhle007]

The lift argument is not entirely invalid but most of you with M20s will rarely ever see the kind of speeds where it becomes a factor.

does anyone have a picture for the mounting plate that goes on the strut, tnx.
