Finally got the notice that the drivers side airbag recall parts were available. Called the local dealer and they had the part the next day and my recall was done in just a couple hours. Comes with a nice new roundel in the middle of the steering wheel



And then today I tackled a little lighting project.

I always felt the AL headlights created a blurry cutoff, so I swapped in a set of OEM ZKW projector lenses using this DIY, and it turned out great





Hard to capture the look in photos, but in person the Osram CBI's look like diamonds. Very sexy looking, and the cutoff is super crisp.

Made another trip to the dyno today.

First I wanted to see if the underdrive pulleys and ATI super damper made any difference.



Nice little improvement above 5k RPM.

Then I wanted to test the difference between the 83mm pulley and a 79mm pulley. My tune has conservative ignition timing and is a bit rich with the 83mm pulley, so that gives me some headroom that allows me to run the 79mm pulley without a change to my tune.



The 83mm pulley creates 10psi of peak boost, and the 79mm pulley makes about 11.5psi peak boost. Both measured before the intercooler cores, which means actual boost is approximately 1-2psi less than that.

Here's an updated NA vs TS2 dyno



Car pulls so strong in the cooler fall air. I love this time of year.

I really like this car. I highly, highly, highly suggest you go clear corners and R/C/R tails

Thanks cosmos! Trying to be very methodical about gathering data on what each change does to the power output. Its always hard to find someone doing a valid independent before/after dyno

Yes, I know what ya mean.

Hopefully in the next couple of months I will finally have my Schrick cam dyno to see how much difference it makes with a boosted engine.

So you have more plans for your engine?

I'd like to install the FI cams and get the car tuned by someone other than ESS. And, I'm interested in doing a meth injection setup.

Also the Magnaflow cat-back is getting too loud for me. It's actually fine at WOT (sounds oh so sexy) but at cruising speeds and on the highway (2k-3k RPM) its a bit drone-y. I was considering installing race-cats but I think I'm goign to try the borla cat-back first. It uses dual 2" pipes instead of dual 2.5" pipes. I think that might help with the sound. And then I'd dyno to make sure I don't lose power.

You would lose HP if you went from 2.5" to 2".

Smaller pipes, and the twin screw pushes more air than NA.

Any FI setup likes more pipe not less. I'll let others chime in, but going down to 2in would be a very bad idea.

Could be a bad idea. Might not make any difference. The header's still shrink down to a 2" collector, so from there a 2" pipe all the way back is simply going to keep velocity up. Theoretically anyway. Thus why I plan to do a dyno immediately after so I'll have back-to-back numbers to validate the change.

So I have a used borla system in-hand, but I dont have a dyno scheduled yet. In due time.

Meanwhile...

Today I completed my first HPDE track day in the 330i, and I LOVED it! Here are some of my notes.

Car details for the day:
Stock ZHP suspension with some poly bushings
Michelin Pilot Super Sport tires, stock wheels, stock staggered sizes
StopTech Street Performance pads, braided brake lines, ATE Type 200 fluid, otherwise stock brakes
ESS TS2, ATI Super Damper, Turner power pulleys, headers, Magnaflow cat-back
Wavetrac LSD, stock drive ratio
Partly cloudy, 72 degrees F



First a note on the pads. I think the stoptech pads are an aggressive street pad, meaning, through normal street driving you will wear off the transferred pad material on the rotor surface that you should have from your first bedding procedure. And, that means you get good cold temp bite from the pads. But, on your first lap or two on track, you'll feel brake fade, but, it will go away. Once you re-transfer the pad material back to the rotor surface after a couple hot laps the pads will really start to work well. I had no more brake fade the entire rest of the day after the first lap or two. On the flip side, after the rotors have a nice transfer of pad material after the day of laps, that cold temp bite suffers again, at least until that transferred pad material gradually wears off. Oh, and even after a track day, I have very little dust on the wheels. I'm quite pleased with these pads.

Second, a note on the tires. I have heard it said in racing all the time that you need to get heat into the tires before they grip well, and I didn't realize how much that applied to a street tire like the Pilot Super Sports too. On the first lap out I can get the rear real loose in 3rd gear, but once I had a lap under the belt I was able to get right into the throttle coming out of turns in 3rd gear and the rear would just squat and plant and off I went. I was very happy with how well the PSS held up too. After a few sessions I had some nice scrub on the shoulder blocks but no chunking or anything ugly.



Which brings me to this e46 chassis, I really think its sweet spot is 300whp or so. With a summer street tire in the stock sizes and LSD, its just the right amount of power. The car is able to put it down quite nicely. I also think this chassis is very well balanced. I did not have any problem turning in at all (I employed trailbraking, which means the front of the car was loaded upon turn-in and it worked really well), I never felt like the front end was plowing at all, it turned in very well, went neutral mid-turn, and then rolling onto the throttle caused the weight to shift and the rear end to bite down and power out. I REALLY liked the way the car felt today.

I'm also happy to report that I didn't notice any heatsoak with the TS2 at all, and I ran her HARD today. It was a pleasure overtaking mustangs, C6 corvettes, and really everything I came across. I'm sure there were quite a few surprised drivers to see an almost 15-year old little 330i pressing in their rear view

I did however have challenges with my tune from ESS. I've had an issue where the car will buck if I ease off full throttle above 4k RPMs. And, on the track, this is downright scary and dangerous. So I'll be taking this up with ESS and demanding they address it.

At the end of the day I'm very happy with the car overall, and I can't wait until the next track day!

Nice looking ZHP! I want to do the same spacers on my ZHP wheels. Considereing pulleys too... Thanks for the cool pics and for sharing the upgrades that you have done!!!

Impressed with the G's you're pulling. Do you have sways?

Thanks, just stock sways. Stock suspension except for powerflex RTAB and FCABs really. And pilot super sports. There was some good body roll.

In fact, the stock sway bar bushings are originals, and I have almost 130k miles on the car now.

So today I installed the PowerFlex front and rear sway bar bushings. Car is really responsive now. I'm not sure it will cut down on the body roll too drastically on track, but on the street the car feels really great.

Also, I got that used Borla cat-back installed.



The sound is definitely different than the Magnaflow. I really do like the Borla, it sounds very German and almost makes me think of Porsche. Also, it is quieter, especially in the lower RPM's, so mission accomplished! I have some before audio from the Magnaflow captured on the GoPro so I'm going to capture the same video with the Borla and hopefully we will have a good comparison.

And, based on my butt dyno I don't think I've lost any power. Dyno is scheduled for Aug 12 so then we shall see.

Looking forward to exhaust videos. Been thinking of getting one for a while now. Also, I would look into a 27mm M3 convertible front sway. The difference is almost unbelievable with no real noticeable degradation in ride quality. Just saying. Build is beautiful!
