Whiteline replaced with SPL. Perfect fit as expected.

Here is something a little more interesting. I dont know about you guys, but my car has very little airflow inside the cabin when on track. It gets VERY hot, a lot worse than most cars.

I decided to re-purpose the rear window as a drivers air vent. These rear windows are insanely glued on. It was VERY hard to remove, and yes when I was 90% done the window shattered into a billion pieces. Just go ahead and smash it from the start. Waste of time.

Ne ways. Glued down some Plexiglas cut to shape, plexi naca duct glued on top of that. It looked pretty messy once all the glue dried up with the few layers. So I plasti dipped over everything nice and thick.

My buddy 3D printed an air guide for the end of the hose. I also used super strong magnets from amazon to hold the scoop to the seat fabric. One on each side. Its stuck on pretty good, and easy to adjust with on hand.

Here is it.

Thats an awesome idea. looks good and functional. A shame about that window

 

Man this thread is awesome!

That Z has come a long way... I see my Z ending up going the same direction. Every day I find my self more and more tempted to just make it a full blown track car.

 

I am really feeling the itch to get out and drive! One month to go.

Da Hell are you running in the next month?

 

FYI/question:

Did you use the NACA duct only to feed air towards the driver?
What about air exiting the cabin?

That is the problem with our car. The rear flapper vents are small (compare to a e46 m3).
Air into cabin= air out of cabin in our scenario. Once the intake overwhelms the exhaust (rear cabin flapper vents) no increased flow will happen.
There is a good chance that naca duct/vent/tube will not push much air at you as your windows has already overwhelmed the vents(ive tried as well).

The solution I am using is a few more flapper vents in the rear. No more heat sickness for me!

 

Care to post pics of your solution?

 

It's at my buddies shop getting a better cage installed.
I can get some in the next week or two.

Essentially we only have two of the below vents:



They are located in the corner of each truck. I made two more flapper vents below where the license plate area is located.

 

LOL. March has a full selection of events. All the usuals, BMW, TT4C, PCA. Might as well!

 

I did drill holes from the rear trunk into the bumper area last year, didnt help much. Thanks for the tip on the flappers. Why not just remove them?

 

Summit Point at all? I like beating up on the PCA guys .

 

Yea, there are a few posted for march on msreg at summit.

Will def be coming down to summit again this year. Lets plan a date. Also Shenandoah, miss that track a lot.

 

No interest in Shenandoah, but I may run the SCCA March event on Main if the car is running.

 

Interesting, I noticed quite a difference!

Well, if you didnt notice more flow with more vents in the rear I doubt flappers would make a difference in that regard. What was your vent sizes you cut?

The flappers are more for lower speed situations (yellow flags) where you dont want exhaust in the cabin.

 

Well I removed the vents in the bumper like you said. Took about 2 seconds. Worth a try.

The holes I drilled are 3" x3 holes.

 

Well the east coast got smashed with a snow storm yesterday, that means finish the race car day!

Brakes all all done. Rebuilt the fronts. Just like last year, the outside seals were toast and the inside were ok.

READY for 2017!

 

ill be flagging this event. well at least learning to

 

Rebuilding Brembos... I don't miss doing that from my STI.

 

2017 is here! First event is in the books. Back to Lightning with Track time 4 cars. We got OVER 120 laps! That's 12 sessions. Light turnout, made for some good fun.

KILLED the brand new pads! Maybe have a short event left on them. Will take it apart and see.

It was COLD but dry all day. Matched my best time 1.18.9.
