Its really 2 modified ATR3350 (didnt know when I purchased it), so I wouldnt really suggest it.

Both mics mounted in the trunk. Going to mount one in the engine bay and one in the trunk next time around.

I'm liking how this sounds a LOT. Where in the trunk did you mount it?

They are clipped onto the top of the lining on the sides. I just made sure the clips/mic wouldnt vibrate/rub against anything.

Damn it! forgot to turn on the mic in the best session.
I attached the Audio-Technica ATR-3350 in rear bumper for today's session, and in the 4th session, i forgot to turn on the mic. I looked at the videos of couple other sessions, they had amazing sound. i might get another one for the iphone to use it with HTL. currently mine is hooked up to gopro2

soon, uploading a 3gb gopro file to youtube is a pain in the ass. so probably by the end of the week, i will have them ready and post the link

Here is a video of my track session on VIR using the Audio Technica 3350 with gopro2

The mic is located at the center of the rear bumper. i will try the licence plate area next time.

But, if I were to use one cam only, and wanted to position it to see my hands, then yeah, these mic's would come in handy.

How do you mount it under your bumper? Aren't you afraid of a big unexpected dip or pothole and losing your go pro?

Sound great! What exhaust setup are you running?

[besiktas]

Everything is stock, the only mods i have in the car is the Performance Friction brake pads hence you hear the crazy brake squeal sound.

After taking the car to track i realized the exhaust sounds much better afterward. I guess it expands due to constant high temperature exhaust coming out and resulting in a stronger sound.

if you go to the youtube channel of that video, you can find periods of cold start and idling while waiting in the line.

Turns out, there is a benefit (other than avoiding tickets) to having the front license plate frame mounted...
.

Picks up the engine sound pretty good...



(this is a little clip from a very high-speed track, where my then-stock brakes just didn't cut it at a particular corner - hence the title "OC3 needs BBK")

For normal street driving, I simply leave the microphone in the trunk and the connector hidden inside the front grille. When I'm at the track, I mount the GoPro on the front bracket, hook-up the connector and run the cable out of the trunk and tape the mic inside the rear bumber via the tow hook hole. I lost the foam that came with it so the video is using the mic with nothing to reduce wind noise. It probably would be even better if I put something on the mic for the wind noise.

For ~$25 and some labor to route and hide the cable, I'm pretty happy with the results...

What app or data acquisition are you using for this video?

what tape are you using to hold it down on the bumper and are you lining the wire up outside of the car or inside?

I'm using my Android Samsung Galaxy S II running Trackmaster app. More info here:
http://trackmaster.trackaroo.com/welcome

To improve accuracy, I'm also using an external Bluetooth GPS receiver; Qstarz BT-Q818X. More info here:
http://www.qstarz.com/Products/GPS%2...BT-Q818X-F.htm

Finally, to overlay my GoPro video and data from Trackmaster, I'm using Dashware. More info here:
http://www.dashware.net/

This is a fairly inexpensive setup and works well for the occasional trip to the track. My only complain so far is that the G force data is sometime not that reliable. Not a big issue and this could be a problem with my phone and not the app itself.

I ran the mic wire from inside the trunk all the way to the front grill going inside the car. If I remember correctly, I had to remove the back seats (pretty easy to do) and the sill trim at both rear and front door (also pretty easy). The only difficult part is to go through the firewall between the front footwell area and the engine bay. I followed the instructions provided by EAS to get the wire from the passenger footwell over to the DME box. Here is the link to the instructions:
http://www.m3post.com/forums/showthread.php?t=329420

Once the wire is in the engine bay, you can simply run it on the edge using zip ties all the way to the front grill. The mic wire was not quite long enough to make the whole run so I bought an 8' feet extension and made the connection inside the DME box.

I store the mic in the trunk for normal DD driving. When I go the the track, I run the mic wire out of the trunk and tape it inside the tow hook hole using regular painter's tape.
