Jake's Epic BMW 135i Build Thread! (5+ Years of Ownership)

[suspenceful]

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!

The rest of the kit showed up yesterday... here are some cell phone pictures of everything. Hoping to get around to installing it next weekend.
