Sure can. PM us your paypal, or order on the website :thumbsup:

I was looking for CSG radiator shroud on your website but I didnt find it

can you help with a link @CSG_mike

We haven't quite released the final shroud yet. There are several cars running the CSG shrouds to help provide additional feedback on our prototype. ;)

Looks like they extend down under the hood quite a bit. Will they work with the Edelbrock supercharger?

Just got it installed on my car with an Edelbrock and it fits with zero issues.

Good to know, thank you.

I have been testing the Trackspec Motorsports hood vents since last year and I 100% concur with CSG's statements regarding cooling and the aero balance change. These are simply the most effective vents available.

Track Spec Vents Track Tested
 

2/21/2016 (no vents) vs 3/19/2016 (vents installed)

Track: Thunderhill West
Ambient Temps: 70-75 F for both days
Setup: JRSC 8psi pulley on e85 (330 whp), ACE 350 Header, ACE FP, Tein SRC coilovers, 255/40/17 Nitto NT-01 tires
Lap Times: 1:25:50 (2/21/2016) vs 1:25:30 (3/19/2016)

Here is a single session (blue is with Track Spec Hood Vents, red is without):
Top graph is Coolant Temp, bottom is Oil Temp

Here is a zoomed in shot to the fastest lap on each day (blue is with Vents):

As far as aerodynamics is concerned, I noticed less understeer this time around. This makes me happy.



Here is some fun footage from 3/19 chasing my friend's BRZ who has pretty much the exact same setup minus the supercharger but + aero. These laps were not for fastest time, just for some fun.

Nice recorded data @sw20kosh! Glad to see that these louvers are working extremely well. @juliog needed to add wing angle to take advantage of the extra downforce! :thumbup:

@CSG Mike

Few questions as I really am interested in a set of these.

1.) How does cutting through the hoods supports effect the overall strength of the hood?
2.) Any rain guards developed? Stuck parking outside all the time :(

I have been looking at the velox louver kit but I kind them too small for my taste however they don't cut through the reenforcement ribs on the hood and they also come with rain guards.

I notice my oil temps getting way up there during my sprinted drives, thinking the oil cooler route but I don't track enough (just some autocross) so I've wondered if venting my hood would be a better route. The CSG ones look badass as well ;)

Edit: Also N/A but going flex fuel soon.

1. Remember, the lovuers are replacing the structure you're removing, and the louvers are thicker than the stock hood.

2. In the plans, but not super high on the priority list; we had a bunch of owners drive through pouring rain to get to 86CUP last weekend, and also park outside in the rain overnight, with zero issues.

If your oil temps are high, you need an oil cooler; hood louvers will not help much with oil temps without an oil cooler. You don't have to be at the track to be driving hard enough to get oil temps up.

All good to know! I am sure I could fab something for rain parking. PNW sucks in the winter haha. Should be ordering soon. :)

A super easy one is to use a windshield cover (the reflective ones that are waterproof) and just put it on your engine, and close the hood on it. That directs all the water to the front of the engine bay.

Be careful to make it so the front is in *front* of your header. You don't want water dripping onto a hot header after you park from a drive.

Interesting stuff... but makes me wonder. You make it sound like you get a signficant amount of downforce in front with these louvers. Assuming an otherwise completely stock bodied BRZ/FRS, if you install the louvers would more rear downforce be needed, or just recommended? And would the louvers be a good alternative to a front splitter? (For me personally, living with louvers in the hood would be a lot easier than dealing with the impracticalities of a big front splitter -- i.e. dealing with ramps, driveways etc.).
