My first BMW E82 135i

Decided to check rod bearings while we had the subframe off to do the turbo. I think it's safe to say these need replacing. They have lasted 3 years and did about 2 seasons of racing.

Toying with the idea of going 10w60 to try help oil temps. And also not sure on if it's better to change oil after every event vs using Motul 300v and doing 4-6 races on that oil.

So a few things were needed for Kyalami.

Added a oil cooler to the mix to help with temps.

Notched the shock towers to be able to dial in more camber.

Did some DIY brake ducting to try help with the brake fluid going off and causing squishy pedal feel.

Waiting on the matching Endless rear pads still, Hopefully before Friday.

Went more aggressive on the tune in the hope to get a bit more speed. Unfortunately this turbo doesn't seem to work well with the pwg actuator it's like it can't bleed enough fast enough for the car to be happy.

Planning on just getting a bigger single turbo going to hopefully solve my power problems.

Kyalami done and dusted.

I expected it to be taxing due to it being over an entire weekend, But damn was I mistaken.

Ran into some unexpected issues with moving the oil cooler up top.... The water temps got too high and the car went into a protective mode which cuts all boost for a bit. Great for a reliable daily, Less Idea when you're chasing a lap time.

So after fiddling with the file ( Not my best Choice tbh) the car was actually even worse. On Saturday I managed my PB of 2:05.6 and my closest competitor was doing 2:06 at the time.

We tried a few things that didn't work and it kept going into limp mode, After a few changes we got it to work right but bow the car felt lazy and a bit weaker than the day before.

The main issue I was fighting now was heat management, I could do 1 lap before the oil and water temps got too high and the car would enter the protective mode again.

Our sessions worked out that your PB enters you into a shootout and that lap time determines where you finish for the day.

I knew I had to give it everything if I had any chance of taking my nemesis. I went too deep into sunset and lost time but managed to edge out the win with 90ms.

It really goes to show how close the competition is in this time attack format.

Below is onboard of my fastest lap.
