    Lol...yeah, the carbon was tearing away from the reinforcement posts on the inside. Which I think also caused 4 of the mounting tabs that connect the halves together break. Originally, I was going to use some sendcutsend brackets to bolt the halves together but didn't hold since the surface epoxy was starting to fail and the material was so thin.

    If that is an example of Evolve workmanship...or at least the company they use to make that stuff...I'd steer clear of that vendor. I could see sunlight through the box...that is how that part was made. I think Evolve used maybe 2 layers of 3k carbon. You will get some gaps in the cosmetic layer, normal. I use a stitched biaxial which will fill in any gaps...which is twice as expensive than the cheaper woven biaxial Evolve used on the inner layer. The clear finish on the box is almost as thick as the carbon.

    I'm sure the box was marketed as high gloss carbon pre-preg autoclave carbon which gets the guys all hot and bothered.

    That was a quick turnaround from my house to your car. That box is shockingly flimsy. Evolve did not do a very good job designing it. The vacuum/pressure cycles are going to cause that box to fail again.

    Yes, at some point hopefully will find a good deal on a Karbonius. Assuming it has a much better build quality

    Yeah moving on alignments probably won't be using a machine too much

    And I also found a calibrated hunter alignment machine to be slightly off compared to a string alignment. I've rolled my car off one alignment rack right onto another and the readings were slightly different. Not so much that anyone would notice but still kind of disappointing.

    So i installed the AFE intake setup, I was very happy with my adapter. However the filter on the AFE is pretty small, and I just didn't really believe looking at it was that much better than a stock intake.

    Long story short ended up with a very well seasoned carbon airbox #009 for the serial number so it's old. Prior to this was on an endurance car until it literally fell apart. It has now since been repaired.

    I was able to make the stock M3 suction jet hose work and used an e28 heater core hose for the crankbase breather. Slammed into the car to make the dyno day

    Did a string alignment to see that Hunter Machine was off on the LR. Why car was feeling a bit weird. Strings ftw. Finally doing toe out.

    4mm total front toe out
    2mm toe in for the rear

    I have been working on more S54 stuff. This car needed some wiring changes done.

    Also was a traveling mechanic for this guy to fix his EML codes. Ended up being he incorrectly rewired replacement plug for TPS sensor. But also installed genuine pedal and all genuine TPS.

    I saw an old AFE Intake sitting there and asked about and he gave it to me. So been finding the missing bits and getting that ready to go in the car. One of things I wanted to do was since going Alpha N was make an adapter to put the IAT in the spot where the MAF is. Just so it was fully reversible and I like that it's measuring temp where BMW intended it too. Right now it's shoved into the airbox to keep car mobile. Using the AFE intake as an excuse to get off my ass and design that. I finally found a use for the cheap Amazon MAFs! Cut it up and used that to get the dimensions, everything was offset and at weird radiuses. Right now it is printed with PETG but will reprint with ASA when that comes in. I could get it made with Send Cut Send or something, but I think plastic should be fine.

    A lot of work to install an intake that who knows if it's better than stock. But this is the most I've felt like I've used my engineering degree since I graduated lol. Really weirdly dimensioned part so that was fun to get pretty close. Still need to 3D print or cobble together some heatshield that is missing, waiting on edge protector and a brand new AFE filter. So I can have two to rotate through.

    Went with CSL alignment settings for Toe this go around, max toe in allowed for rear on them

    Going to string align it tonight and verify what that is in real world mm for toe settings so I can diy that later on.

    I had a dyno with the HTE OTS Tune, so I can compare to that 'ish. Different dyno and weather so sort've Apple and Oranges but good enough for me.

    It's Alpha-N so with him mandatory to strap it on a dyno and make sure everything is happy, that's the main reason I am going.

    Only real pictures I got of it were the marks I did for the pinion nut.

    Oh I also installed some used takeoff Bimmerworld Race Camber Arms, my originals definitely were tired and deflecting

    Had to weld up the Bimmerworld exhaust some more

    Also on Epic DME software now! MAF is no more, per his recc I went that route. Super happy with drivability and idle. I was worried about that, I have a dyno day scheduled soon, so going to get that soon.

    Painted the bumper came out good, very happy with it. Probably won't even end up doing a cut and polish on it.

    I think I will have to redo the hood at some point. It is like hazing? idk what it is but in most cases it doesn't really show up. Here I was able to catch it in the camera well. Now that the wax is off you can tell in direct lighting. I will probably just wax it often Untitled by Sam DaJam, on Flickr

    But for a daily/track beater thing. It's more than good enough for me. Just want to finish up fixing some fitment issues on right side and call it a day.

    Redoing hood will be much later down the line. It's been great to learn how to do all this and not have to take it a shop.

I have been woring on getting him to come out in that. I doubt he will take his E92 M3, or his E28. Just my dumbass carrying the torch.
    I remember that because I had the same wheels on my car that day. I was quite worried...but I drove anyway lol
