Default cooling options v.splitter

I'm about to get crazy with the cheese wiz. I have an r-pack lip, begi scooper, and here we go...should I:

a. keep the r-pack lip and get the begi scooper that fits below it?
b. cut the r-pack lip for the standard begi scooper, and make a big splitter for it?
c. something else

I still have to figure out the oil cooler too.

Also, do the r-pack lip brake ducts move enough air to be effective?

Do you have pictures? I may want to buy one if you do something different.

a. don't cut it.

IIRC, Gary has brake ducting from the NB lip, and it works pretty good for him.

I'm keeping my fingers crossed that my BEGI "street" reroute is good enough for the track this year. It sure as hell takes a long time to warm up now....

I wanna take it out on the Jan 19th trackday @ Harris Hill ($150). PM me for details, only open to certain clubs right now.

If you value a little ground clearance over the aesthetics of having an intact lip then I say go with B.

Also, you haven't updated your AV yet.

I'd call BEGi and ask for their experiences with the different scoops.

I'm going to just drop the car off with them on Sunday.

I don't know how many cars they've put their kits on which see track time though.

a splitter in front of the scooper is going to reduce the effectiveness of the scooper.

the splitter's job is to prevent air from flowing down under the nose of the car--and make it flow more over the top or into the mouth.

so you could:
* not get the scooper, but run a TDR splitter on your r-lip

* get the scooper and not run a splitter

* get a fancy splitter that has no middle and make something that has a reverse diffuser leading into the scooper. visit that fancy race car tech site you posted here a while back for ideas.

the r-pack lip would be cut, with the scooper in the cut out...then the splitter on the bottom of both the splitter and the air dam.



Does anyone know if the brake ducts in the r-pack spoiler are big enough to get the job done?

I see no reason the ducts cant work....the odd shape sucks, but when i was looking at it, a simple rectangluar brake duct should be able to be fabbed to work with the hole...

then plumb to these:

The R-lip ducts work well - if you add the hosing to compliment them. Gary is on the right track, and I have planned on the same. I have deleted the dust shields and will be adding ducts to go directly to the rotors. The holes I have cut in the bumper before I added the R-lip, will then be enlarged to make on continuous opening. Should look about like a Porsche Turbo at that point.
For the frustration it takes to find a lip these days.....I say do not cut it.
A scooper below that, will be very low....and will get abused as a daily.

the scooper on the bottom of the splitter and air dam? that's what I'm saying is pointless. you're going to have a splitter prevent airflow under the car and then a scooper to.... do nothing.

that is what I was thinking. It would still have the shape with the TDR splitter (twice as big though), paint the scooper black, and run a tray back to the subframe.

I think this will make the most of cooling and downforce. Its really going to hurt my soul to cut that lip...big time. I think this is my best option, with the FM hood, to keep the car cool on the track...and prove everyone wrong about a turbo miata on the track.

OK then that is win. you could see how I was confused what with hustler saying he would cut the splitter and have the splitter below the splitter. splitter.

Hmmm.....seeing an example actually used, it doesn't look too bad.
