I plastidipped them black the night before leaving. Better than the dirty factory finish, in my opinion.

Just got back from a long weekend. The event was great, but very hot. Real-feel of 110-115* and very humid both days. I was very careful with the car, turned down the boost and didn't make a ton of passes. Had a few hiccups, but still a solid turnout. Stay tuned for a video soon!

When's the RA video going up?

Sometime in the next month! It won't be anything crazy because all I have is GoPro footage from the event.

Nice time considering the temps. Did you log the iats? I'd be interested to see that.

Yes, most times they started between 110-130*F, then dropped during the pull and eventually rose up a bit at the top end. Never really exceeded 140*F.

When does it start pulling timing? Is it in stages?

My tune ramps up timing to redline. It gradually increased to 9* at 7k RPMs. If it senses knock, it will pull timing until the knock goes away.

I've never n54'd before but I can see it in my future

Full video is finally up

Did you have the AC on during pulls?

It was on the whole weekend. Sometimes I turned it off right before the hand drop, but sometimes I didn't.

Drone shot was great! There are some serious machines there!

The photographer from the Road America event I did in May finally sent me some pictures! Man this was fun...

If anyone wants to see the footage from when my girlfriend took my 135i down the airstrip...

[patsbimmer1]

That's cool that she got to experience that with you.  Time to boost the e46!

I got a Dragy device to measure my 0-60, 60-130, 1/8 mile, 1/4 mile, 1/2 mile data. I finally put it to the test the other night and thought I'd share the results.

Most people on this platform measure 60-130mph to get a good idea of power/acceleration, so that's what I did. Car was at 27psi with a full tank of gas and a passenger. I'm pleased with the results, but know there's a lot of room for improvement. Gonna try again by myself with 1/8 tank and see if I can improve the shift bog.

Pretty cool to see the rankings

I don't know man, looks like you were going downhill... i'd have to say that's not valid.  No internet points for you!

Seriously though that's kinda neat.  Is there a box that comes with an accelerometer and gps unit that records this or is it from your phone?

Lol, I know you're kidding but it requires less than 1% slope for a "valid" result. Most drag strips are downhill between -0.05% and -0.5% slope. I did a couple runs on roads that looked flat to me, but were at a -2% slope. It still gives the results, but isn't "approved" for the leader boards.

It's a tiny magnetic box (maybe 3x1"). You just plug it's cord into a 12v socket and open the mobile app. It's always recording data and will split it up into different stat sheets based on the distances/speeds you were going.

Thats pretty damn sweet!!

Finally. I received my Doc Race intake manifold last night! You could order it in black, silver, red or blue. I opted for silver because I'm not a huge fan of colors, but wanted it to "pop". It matches the turbo compressor housing nicely. I'm going to take a sanding pad to the raised logo... should give it a nice brushed finished.

I couldn't help but to set it on top of the factory intake manifold to get an idea of what it will look like once installed...

Stay tuned for a "first impressions" video on my YouTube channel. I'm also planning a full installation DIY video, along with a same day back-to-back dyno session to see the exact gains this intake manifold provides. The custom charge pipe and port injection accessories should be arriving later today. Stay tuned!
