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

Lol, if this isn't the most depressing log I've ever seen.
Doesn't hit full boost on these tiny twins until 5k RPMs. Everyone else hits max boost at like 3k RPMs. It's a solid 3.5psi under target the whole way as well.
After I took the log posted below (~91 pump gas), I filled up with an E55 mix and was able to hit 16.5psi.
I have a weird suspicion that JB4 isn't helping me right now. I might try just flashing the ECU with MHD instead of using a piggyback to see if I can gain some spool time and boost back. Otherwise... it's time to start stacking cash for a turbo upgrade.

Ouch! I'm so thankful I was able to get my turbos taken care of under warranty when I did. Bright side, you're going to have one hell of a car once your all done! 700whp or bust!

I'm kicking myself for not being more persistant about it. Everything else on the car is new and I just walnut blasted it as well.
We'll see what it puts down on the dyno in two weeks. I have a feeling it'll still be decent numbers, but not what I was initially hoping for.

rofl Pat. 700 whp on the street would be utterly useless in this car. You would need to be able to stuff a 295 or 305 tire on the back to have any prayer of hooking up and that is physically impossible without ponying up for widebody flares + paint == a few thousand bucks, and if you don't do the front flares as well your 135i then looks completely retarded.
with slicks at airstrip race events you could get away with 265s but on street tires, no chance of traction unless you are running wider. Don't encourage him to ruin his car

Utterly useless... but not impossible.

Look at the log I posted a few days ago, then look at this one. Note the boost level and the RPM that I reach full boost. My dick is so hard.

So what's physically changed with your car? Was it the flash tune?

Nope. It was my dumbass fault. When I was installing inlets, I tried tightening the wastegate rod to eliminate the rattling. After seeing the poor performance, I wondered if I loosened it instead. I got under the car and beat the shit out of my arms to spin the rod the other way. Sure enough I actually loosened the rod the first time around. Now that it's tightened back up, the car hauls ass.
-
live and learn but I'm not surprised at all - I've never really had to adjust the actuator rod but from what I read it's super sensitive. Glad you got it fixed in time for NFZ ! in 4 vidz

Haha that's awesome. At least you figured it out!

Whipped up a custom kill tune for a glory run on the dyno and if I need the edge during a street race. I can switch to this map with a press of a button on the steering wheel. Targets 23psi with a slight taper to redline. Probably room for a little more, but I don't want to push the limits (I already am, LOL).
Also took a picture of my car while I was out.

What does your timing look like?
-
that's gross, in a good way. Are you still getting on the dyno before NFZ?? You should just run at 23 target all the time so your turbos burn out faster and you have a good reason to upgrade

Overall, I think it'll be fine for a dyno run or if I need it. Timing is pretty good overall. A few drops map 6, but I think it might be sensing false knock.

Yup, dyno tomorrow. I'll see what it puts down on my custom map, but I'm going to dyno on map 7 as well. That's the map I plan on running most of the time. Not trying to blow these up. Besides the rattle, they seem to be holding up just fine!
-
Car spun tire in 4th gear on the dyno. Couldn't get an accurate reading (IMO) because of it. Made 433whp/420wtq.
Mounting new tires this week and hitting up a different DynoJet on Friday.

What tires are you currently running and what are the new ones you are putting on? Lol, currently have some Michelin Pilot Sport A/S 3 (all-seasons) with barely any tread left. Putting on some brand new Michelin Pilot Super Sports (PSS).
It made 497wtq on the first run before the guy let off because it was spinning.

yep that makes a lot of sense lol. where are you dyno'ing on Friday? Are you going to be in MKE still on your way to NFZ? If you are dyno'ing nearby maybe I can stop out. I will be downtown.

I contacted Late Model Throttle and they said they'd do it, just waiting to hear back about availability. I will be staying in Milwaukee Wednesday and Thursday night. Would probably dyno on Friday our way to NFZ. If you'd like to stop by, I can give you the time if LMT has an open slot.
-
sweet if they can get you in let me know what time. I have a lunch appointment but otherwise should be open to make a stop in. I won't be ready to dyno yet I don't think, probably next week. Adjustments still being made to map 6. It may get sorted this week still but probably not going to know in time to be able to get on the dyno by friday. ;/
