Default Thundermoose Track Car Journal

A little late in the making but wanted to share some stuff about my car.

Bought this car in Jan 2012 from a guy in Chicago. I think he bought it from a track guy but never tracked the car himself.

The car was an 2003 Steel Grey SMG with 23,000 miles. It had a Fall Line half cage. It also had Cobra Imola Pro seats with Schroth 6 point harnesses. Brembo BBK in the front with KW V3 suspension all the way around.

Forum member Disapr bought his car shortly after mine but basically defined the path that my car would take. I am not nearly as meticulous as him, but was able to get a lot done over the last 3 years.

One of my first jobs was to strip out the rest of the interior and also install a CF roof. A big leap of faith there for me as you have to drill out 80+ spot welds. I punched through twice so all in all very good.

Sometime right around there, I had the subframe re-inforced and installed a Zionsville Competition Cooler w/ BW Oil Cooler. I also had all of the mounts upgraded to solid.

I was still having some elevated temps at the track, so I went ahead and deleted the AC. That helped a bunch and I have never had any temp issues even in Texas summers.

Not shown in my journal was the installation of a BW 3.5" race exhaust.

In late 2013, I started doing NASA Time Trials. Due to my modifications, I classed out in TT3. My car was not very competitive. Neither was I, but that's another matter. In 2014 I installed an Evolve Intake with Euro headers to get a bit more power. I used the Evolve Alpha N tune. I had a lot of misfire issues from 3k to 4k, so I took everything back to stock.

I did the Beisan refresh of the Vanos which I believe was the root issue. I then re-installed the Evolve intake and went with CPI stepped headers. I opted to go with Epic for my tune. I haven't had an issue since.

As mentioned at the beginning, the car came with KW V3 suspension. One thing I didn't like with that suspension was the inability to change spring rates. I wanted a bit stiffer set up. I tried Hotchkis sway bars at first thinking that might help. Eventually, one of the front dampers bit it, so I took that opportunity to install MCS 2 way non remote with 550F/650R springs. I have Rogue RSM's. I have been very pleased with the set-up.


One of the issues that always plagued me at the track was the occasional missed shift from 3rd to 4th at WOT. I tried everything - software upgrades, resistor mod, spring replacement, tranny fluids - but nothing seemed to work. I decided to go ahead a install a 5MT. I went with BW solid shifter. No pictures of the install. I love the 5 speed. Makes driving a ton more fun and it also shaved a few pounds.

Deciding that there wasn't a whole lot of HP to gain, I decided to go after more weight. In the past months, I have done the following:
  • Replaced stock battery with 6 lb Braille
  • Thinned out the wire harness
  • Removed sound deadening. Rattle canned the inside with SG spray.
  • Removed door windows and door cards. I made some travel windows.
  • Replace rear windows with 5 star bodies polycarbonate
  • Replaced headlights with BW blanks

I expect the car to be very close to 2700 pounds with quarter tank of gas.

I still have some WT/HP allowance in TT3, so will probably install Aero later this year or early next year.

Very nice build. It's fun to see a race car build in this section.
The wiring thinning job looks very tricky to do

Nice build.

And to me, Phoenix Yellow and Laguna Seca Blue are two of the best ways to differentiate your M3 experience from the norm.

This. Care to elaborate a little on the process?

The wire thinning is not for the faint of heart.

Basically, I had removed air bags, the radio, climate control, AC, and headlights. So there was a lot of wire that went no where.

Once you get the dash off, you get access to a lot of this wire. I also had to pull out the DME to get access to the firewall to pull the lights wire through.

After that, you start unspooling tape or felt to get access to all of the individual wires. Once the wires become unwrapped, it's a real bear to put it back the way it was.

For the everything that I knew that I would never use again, I cut one end off and then pulled the wires back to a connector to one of the modules (LZM, cluster, fuse panel, ECU, etc). I use a myriad of terminal tools to remove the wires from the connector.

Once I removed all of the wires, I used some Painless Performance braiding to bundle it back up.

At one point I had a giant rat's nest that would not allow me to bundle the wires. If I was I to do it again (which I am not sure I would), I would've been much more careful about keeping the wire bundles and routing together while removing wires. You just need it loose enough to be able to follow wires.

Instead, I had to disconnect a bunch of wires going to the general module behind the fuse panel. This allowed me to untangle the knots and reroute the wires the way I wanted.

Another extremely helpful tool was the website below, which provides wiring details for every electric component. I also used my multimeter a couple of times to check continuity on a couple of wires to the trunk area.

http://www.bmw-planet.com/diagrams/r.../e46/index.htm

Eventually, the moment of truth arrived and I attempted my first re-start of car. The car cranked once and everything went black. Luckily, one of the ground connections had come out of a butt splice. Hooked it back and voila car started fine.

A few updates

I started tracking with SMG, but swapped this year to a 5 speed. So to a certain extent, I got fast without worrying too much about shifting. In Time Trials, I started having problems with 2 to 3 shift with BW shifter. Not a shifter issue per se, but I was looking for something to make it easier. Brysen (Feuerbach86) and Disapr bot had CAE shifter which auto-centers on 3-4 and makes it super easy to go 2-3 and 5-4. Here's a pic of it installed. I love it. Still gotta be careful with 4-5!



After doing WRL event in friend's Miata with Traqmate with integrated shift lights, I decided to install lights on mine. I have it set so first green light comes on at 4k. Helps me keep car in power band through turns and/or determine whether or not I may want to downshift. It has a lot of configuration options.



I never really had mirror issues with stock mirrors, but wanted to expand my line of sight regardless.

Wink Mirror


After BMWCCA HPDE event, I noticed the car seemed louder. Add to that a tinging noise, when I got it on trailer, I decided to inspect. I found the weld to resonator broke.

Broken Exhaust


I had a local shop weld in straight piece to get me by. BW swapped to magna flow and you can't just buy a center section.

Repaired Exhaust


I decided to use the opportunity to swap to diffuser exit and replaced my hacked up rear diffuser with the BW piece.



Per NASA TT rules, the diffuser is counted as aero and incurs a 0.4 weight to hp penalty. I hadn't planned to go to aero until next season, but since I was already committed, I ordered the AJ Hartman Splitter and the BW rear wing. The wing has not yet shipped, but the splitter arrived this past week.

Prep for Splitter


Front View and rear view of splitter



Installing the splitter messes up the stock brake ducting, so I decided to fully block off the right and left foglight/duct openings. I have a 6" duct to port air into my Evolve box.

Oh my. I want to see the aero in person. Any plans for a CSL trunk to lighten up even more?

The battery still makes me

I am going to stay with OEM trunk. Depending on what size tires I run I may have to actually add weight back to comply with NASA TT3 rules.
