notice any rasp? and can you make a video sometime i would love to hear how it sounds

 

I really can't hear it rasp that much. I tried to take a driving video but failed badly. Lol.

Bought some goodies for my Sony action cam to reduce the wind noise. Will do a reshoot when I get them.

 

have the same problem with my gopro what did you get to help with sound

 

For the GoPro, they have the "Rabbit Fur" that acts as a windshield to reduce wind noise. You can find it easily on ebay. It's an easy plug and play.



For my Sony HDR-AS100V, you can see the two microphones in the front, which is horrible for filming in the direction you are heading towards.



So, I had to buy that Rabbit Fur, but will be cutting it, in order to cover the 2 microphones. This should help a lot. We'll see...

 

Just wondering what your using to mount the action cam on your car ? I have a dash crab but it seems suspect to me.

 

This mount (Windshield/Dash Flexneck Camera):



I mount it either on the inside of the driver's side window at an angle, or on the moonroof from the exterior. I don't like to mount on exterior of the car because it doesn't feel safe, so when I mount on moonroof, I tie a little string around it. That way, in case it falls down, it won't go flying off. However, the video was still shaky since the mount is a bit long. I also have a short mount that works as a suction, which might work better for exterior moonroof mount. I'm still figuring it out and testing for a good view and sound.

 

haha thats what i do too tie it with a wire better safe than sorry

 

Back at the shop for NST pulleys install...

Also, testing out action cam for exhaust sound. Don't have a co-pilot so I can't get different angles on the shootings.

 

Tell your job you need to take some time off so you can update us with video's, new dynos, pictures, write-up's etc.

We are counting on you.

 

lol. I don't have a job at the moment. I'm a full-time student, thankfully.


Now about the NST Pulleys:

The install seemed to be a bit of PITA. The problem seemed to be removing the crank bolt.

As for the butt dyno, the throttle is definitely more responsive. And about the gains, we will see about that on the dyno (soon).

Would I recommend this mod?

I still haven't tested it enough (dyno, track, etc.), but for now I would say that this mod is nice for those of you looking to squeeze every last bit of N/A power. If you are planning on FI or trading in the car soon, then I would not recommend.

 

Here is a short video of MXP RTPs paired with ARK.
I know video could use some improvement. Still working on getting the best sound.

woops.
Fixed

 

Here is some info about the weight differences of the NST vs. OEM pulleys.



That's 1.23 lbs vs. 4.66 lbs for the crank pulley
and 0.18 lbs vs. 0.52 lbs for the alternator pulley.

 

Wow, that's a significant difference. Any perceived issues with balance?
