The First Track Day - Nothing fell off!

March 30th, 2009

I’d been working my way through the project list to get the M3 ready for the first track day of the season. My goal was to get it out there and see how it ran in order to help me prioritize mods and maintenance.

I wasn’t quite sure what to expect, other than massive brake fade from the stock pads and lots of tire squeal from the General UHPs. I was worried that I might lose steering fluid under hard load, burn oil, blow a shock…you name it, I was worried about it going in.

Fortunately though, it turned out great. Other than the fade and rubbish tires, the car ran like clockwork through the 4 sessions. Even the dodgy sway bar setup that’s on the car at the moment (stiff in rear, soft upfront) didn’t cause any problems - in part due to the massive “push” (understeer) courtesy of the tires and stock suspension.

So all in all, it was a successful day and I am much more confident in moving onto mods, knowing that the car can handle it out there. Stay tuned for some new stuff coming this week!

Test Drive: Porsche 996 Turbo Cabriolet

March 24th, 2009
Porsche 911 Turbo Cabriolet

Porsche 911 Turbo Cabriolet

Porsche 911 Turbo: So there I was at the Porsche dealership in Denver, pretty upset about my drive of the bland 996 Carrera 4S.  I hadn’t reported it, but I’ll detail it later in this review, I also drove the 996 Turbo Coupe with a Tiptronic transmission. Summary: The Transmission ruined the car.  Somehow all these cars were Arctic Silver Metallic, which was a very nice looking Silver color for a car, but about as exciting as Silver can be.

The Porsche 911 Turbo Cabriolet was definitely a different beast from the other two cars I will admit.  Most notably, there was gobs of acceleration - tons of it.  The roadfeel was significantly improved.  The communication was also improved with respect to the clutch.  The gearbox was still very numb.  With the sun setting, I hopped into the driver’s seat - brother in the passenger seat, popped it in gear and crept out of the parking lot.  The car had been idling for several minutes already, so the warm-up period was much shorter.  The car in general was very composed at regular city street speeds.  Immediately I knew I was in a different car than the C4S.  The Suspension on the 911 Turbo was much more stiff and communicated the road feel much better. The Turbo also felt lower to the ground, and the low end grunt was much more satisfying, even at part throttle, than its sibling.  There was more feeling in the clutch, so I could actually feel it engage and disengage, but I would still say it was like reading braile through leather gloves compared to the clutch in my M3. Action on the clutch was very light, so sitting in traffic with it was not very challenging.  Like the Porsche C4S, the gear lever was very light and silky smooth in its action, but still very very numb, and a fairly long throw.  After a short time, the engine had warmed up and we were ready to play.

I pulled up to a stop light in the middle of a very long straight section of road.  The cool air above, the noticeable LACK of heated seats NOT warming my ass, and the signature burble of the Porsche engine behind me.  My left hand on the steering wheel, my right hand on the gear shifter; we sat in silence, just looking straight ahead.  The light turned green and I began releasing the clutch while pressing the gas.  At first, the car lugged forward almost disappointingly.  This was my first aggressive (not balls-out) launch of this car though, so I wasn’t concerned.  I mashed the gas pedal and the revs climbed.  Somewhere around 2,000 RPM, I could feel the turbos start to spool.  And suddenly - just like in the Cayenne Turbo - a tidal wave of acceleration roared over us.  1st gear was gone in the blink of an eye, 2nd gear mashed us into the backs of our seats as the Porsche rocketed past 60 mph - then 70 - then a shift to 3rd - 80 - 90 mph.  The grin that was left plastered on our faces meant only one thing: This car is fast as hell.

We spent the next 40 minutes blasting through the gears and reveling in the breakneck acceleration.  The whole time, not even a threat of wheelspin because the All Wheel Drive kept the tires firmly planted.  Cornering in the car was great as well - again the feedback in the steering and balance was great.  The car was very composed on corner entry and exit.

A Note about TipTronic:  The 996 Turbo we drove with TipTronic was a bit old (2001), so it’s possible they have made updates since then.  The Tiptronic was TERRIBLE.  I would call it the TipTragic.  Shift times were north of 1/2 a second and there’s no aggressiveness setting.  The experience was absolutely awful, so after a very very short run, we returned the car and swapped out for the 6 speed manual.

Things that went wrong in the first week, and project list.

March 18th, 2009

After a week of owning the car, I uncovered and/or created a few problems. Here’s a sample:

  • Gear knob came off in my hand while downshifting
  • Got stuck in a snow storm and almost shunted the whole thing into a wall, then drove sideways for a mile at 30mph with the door open so I could see where I was going
  • Overfilled the coolant and had to suck some of it out with turkey baster
  • Tried to take the headlights out and broke a bunch of clips. Old plastic isn’t flexible when it’s 30 degrees outside, apparently.
  • Hood fell on my head thanks to 14 year old struts and nice winter breeze
  • While replacing hood struts, took the fuse-box cover off and placed it on the motor…but forgot about it and slammed the hood. Then couldn’t get hood open.

Add this to the list of maintenance work that has already been done/needs to be done, and it’s looking like a busy Spring:

  • Oil change to move from 5w30 to Mobil 1 15w50 [Done]
  • Replace tranny fluid with Royal Purple Synchomax [Done]
  • Brake inspection, bleed and flush with Motul 600 [Done]
  • Replace coolant level sensor (throwing code on dash)
  • Replace airbag occupancy sensor mat under passenger seat
  • Replace differential seals and fluid
  • Replace power steering hoses and reservoir, and bleed system
  • Replace clutch pedal bushings

I’m sure there’s more stuff, and this is before we even start thinking about modifications.

The Beginning…

March 18th, 2009

So this is how the story began. A story that is already making my hair thinner, my weekends shorter, my wallet lighter, but everything else much more exciting.

I was toying with the idea of another Miata (would have been my 4th) and then supercharging. Weeks of searching local classifieds wasn’t bringing up much, and while it was comforting knowing the cars inside and out, I realized that I’d be spending a ton of money to basically do the same as I’d done before.

I spread my search out and started looking at E36s M3s. I’ve had an E46 M3 for almost 3 years now and had been assuming that an E36 would be out of my price range. I looked at a couple that were affordable but beaten to death, or “modded” by children who like shiny carbon fiber and lots of armor-all. Then I came across this one.

The bad:

167,000 miles (that’s around the world 6 1/2 times)

…and that was it for the bad.

The good:

Maintenance record folder and inch thick - Everything that was supposed to have been done had been done. Cooling system replaced, control arms, shock tower reinforcements, fluid changes. You name it.

Paint in great condition except for a couple of dings; overall decent interior including Vaders; modest mods including chip, intake, sways, shock-tower brace, underbody brace.

It’s a 1995 - To most this is a “bad”. However, I’ll take OBDI over OBDII anyday. It’s also plenty quick for me and since it’s not going to be a daily driver (DD), I just don’t care about some of the other differences. Harder leather? Who cares.

The purchase was made a week or so later after getting stuck in Atlanta with work, and catching the stomach flu. Nice.  And so the process began. Update coming soon, including what I found (and didn’t find) when it went up on a lift, and the discovery of some interesting problems.

Test Drive: 2002 Porsche Carrera 4S

March 17th, 2009
Silver 996 Porsche C4S

Silver 996 Porsche C4S

Last weekend I found myself sitting in a 2002 Silver Porsche Carrera C4S.  This is the 996 Carrera widebody rear engine four wheel drive Porsche that has been popular for many years.  It was a cool evening in Denver when my brother and I headed down to the local Porsche dealer to do the drive.  This particular car had about 20,000 miles on it and the paint was in beautiful condition.  The dealer shuffled a few cars out of the way while we got in - my brother in the driver’s seat initially, while I sat in the passenger seat.  To be honest I wasn’t sure what to expect.  I had never ridden in a Porsche 911 before, let alone driven one.  I had read review after review of them though, and the 911 Carrera has always been one of the most highly regarded sports cars out there.  To be honest, I don’t think any of those people who reviewed the 911 had driven a C4S.  A turn of the key, and the engine roared to life.  We were in their covered parking area, so the sound of the sport exhaused filled the room with a very attractive metallic growl. We slowly rolled the car out of the garage and puttered out to the main drag.  The engine was cool, so as we pulled into traffic, my brother didn’t accelerate too hard.  At low speeds the car felt just about like any other car.  He continued to drive slowly for the first 10 minutes or so before cracking the throttle open.

Interior: The Porsche C4S was certainly appointed nicely.  Like any German car, the soft leather adorned interior featured subtle stitching and a very solid feel.  The doors made a nice heavy “thump” when you closed them, the handles were made of aluminum, and the switches were all solid plastic.  The shifter felt a little odd in my hand, but was definitely solid and obviously of high quality craftsmanship, while the Bose sound system pumped the tunes out with a great sound.  Of course, the orchestral exhaust note was much more pleasing to the ear, so the stereo was quickly turned off.  The leather-wrapped steering wheel felt nice in the hand, but was noticeably more skinny than the steering wheel of my M3. Still vastly better than the average Dodge Caravan though.  The dashboard display was fantastically put together.  Consistent with Porsche Tradition was the tachometer directly in the center, and the largest dial on the dash by a considerable margin.  White numbers counted up to 7,000 RPM where the redline kicked in.  The Speedometer clocked up to a healthy 200 mph, which is always fun to see on a Speedo and made me feel a little jealous that the speedometer in my M3 only showed a “180 mph.”   You sit down very low in a Porsche Carrera.  Even compared to my M3 it felt low, with the dash seeming to loom almost above your head - but visibility was still very very good.  All the switches and knobs in the Porshe C4S were in the right places.  The seats were adequate, but they weren’t the sports seats, and had about as much support as your typical 3 series BMW or C class Mercedes.  Hard corning in this car definitely sent you sliding around.

Steering & Feel: It’s hard to deny that the steering wasn’t sublime in the Silver 911.  But would I say it is significantly better than in my M3?  No.  Better than the steering in my dad’s 330ix? Yes.  I noticed immediately that, although the soft leather and curves of the Porsche steering wheel were incredibly comfortable in my hand, I did not get nearly as much road sensation communicated to me as I would have expected from a car that had been hailed to be such a masterpiece for longer than I’ve been alive.  The other really irritating thing about this car was the fact that the clutch was completely numb - and I mean absolutely totally numb.  There was zero feedback to my foot through my driving shoes that the gear was engaged or disengaged.  So bad was it, that when I did a hard launch off the line, I made the clutch smell like someone left a rubber boot in the oven while the Thanksgiving turkey was cooking.  The shifter was also incredibly numb.  The shifting motion was incredibly silky smooth - and made the shift action on my M3 feel very notchy - but you couldn’t feel when the gear had actually been engaged without using almost full concentration.  Between that and the numb clutch, I felt like Ray Charles trying to drive an 18 wheeler.

Performance: To be fair, we didn’t have a super twisty mountain road to take the Porsche onto.  In fact, we only turned right the entire time because we were a bit short on time and could only do a large square circuit.  Thankfully there were a couple of sweeping right corners to take at a nice speed.  Once the engine got up and running, my brother did some hard accelerations and corners - but hard to get a sense for how quick it feels as a passenger.  After a lap that was about 2 or 3 miles long it was my turn to take over the wheel.  He pulled into a quiet side street and we swapped chairs.  This is of course when I first noticed how freakin numb the clutch and gearbox were.  I pulled the car out to the main drag and pulled into traffic.  Immediately I noticed a lack of potency, but I was still just getting used to the car and how it felt, and thought maybe I just hadn’t pushed the car very hard.  I came to a stop at a light and prepped myself for a decent launch.  Wasn’t looking to smoke the tires or anything, but wanted to get a good launch in.  I revved the engine to about 2k RPM and let the clutch out.  With about as much excitement as my wife’s 4 cyclinder Honda Accord, the Porsche crept off the line.  “Okay,” I thought,”I’ll give it a bit more gas.” So I depressed the gas pedal further and further as the tach climbed to 7,000 RPM, shifted to second, and then hit the gas again.  I noticed I was really having a hard time pulling away from traffic - so I hit the throttle even harder.  Only to realize the gas pedal was already pegged.  The Carrera 4S was pulling about as hard as my M3 in 4th gear.  Okay, so it’s not the most exciting engine.  I thought the beautiful chassis and wonderful steering would save the day.  As I approached the upcoming righthand corner, I applied the brake, which felt incredibly weak and cold.  Now almost in a panic, I mashed the brake to slow the car before heading into the corner.  I now had slowed down too much and was at the bottom of the RPM band in 2nd gear.  Used to the low end grunt of my M3, I mashed the gas pedal down and the masterful Porsche 911 anemically groaned its way through the corner.  About 50 yards after the corner exit, the 6 cylinder engine finally found its guts and accelerated reasonably hard from 5k to 7k RPM, before I  hit 3rd gear and again found myself pining for any kind of acceleration.  It was at that point that I turned to my brother and asked

“Is there a sport button in this thing that I’m missing?”

Which pretty much summed up my experience in the 2002 Porsche Carrera 4S.

Track Day Prep

March 10th, 2009

So I’ve got a track day coming up in June and thought I’d start making my list of gear that I need to pick up.  Here’s what I’m looking at right now:

  • Cool Willy Racing Brake Pads: $157.95
  • Motul RBF 600 Racing Brake Fluid: $19.80
  • Turner Motorsport Stainless Steel Brake Lines: $99.95

The Damage shouldn’t be too bad overall.  Cost of install and labor might be a couple hundred bucks on top of that, so I’d be looking at around $500.00 to get my car prepped for the track day.  Once I order it up, get it installed, and run with it, I’ll let you know how it goes!

Oh yeah, and I’ll need some new Michelin Pilot Sport 2 Tires, which will set me back about $900 + tax :-(

Two Car Detailing Tips

March 9th, 2009

Okay, so I haven’t made too much news of it, but I am also a nut about keeping the M3 polished to a brilliant shine. Here are two spring cleaning tips I’d like to share from my trials and tribulations:

First: I had some old wax build up in some of the crevises … I’ve tried using Griot’s spray on wax to remove it in the past and it takes a lot of work and doesn’t ever really get it all off. Today I tried rubbing alcohol on a Q-tip and voila! off it came! a quick buff with a micro-towel to remove the alcohol and the crevises were sparkling like new. It’s possible that if allowed to sit for too long this may be damaging to the clearcoat, but I’ve heard of acetone being used to remove bug & tar before without damaging the clearcoat. It seems A-OK so far.

Second: S.O.S. pads to clean out my exhaust. less than 2 minutes of scrubbing and the inside of my tailpipes sparkled like new. Of course this isn’t recommended for the outside of the tailpipes, as the steel wool would marr the finish.

Enjoy!

BMW Z1 Roadster

March 4th, 2009

The BMW Z1 Roadster isn’t a car that got a lot of press or made it very far from the Manufacturer. I just found out about it today, and I have to say, the Z1 Roadster is an abomination.  It’s possibly the largest mistake to ever roll out of Munich.

In the 80s BMW decided on a contest between their own development teams BMW “M” and BMW Technik. Both groups were asked to build a new innovative car. BMW Technik dug deep into their desks and came with doors that disappear into the body, a 2-seater Roadster (this is before the Mazda Miata revolutionized the open car market. One of the highlights of the car is that all painted body parts of the car are fiberglass and can be removed and exchanged for a different color. Separate body kits were made available in all colors.
The car is loosely based on the 325 model with modifications to the frame. Many of the modifications and innovations that came from the Z1 design and project were later implemented into the BMW series of the 90s and into today.

The car was never made available for the US market. Only 8000 total units were built. Waiting lists in Europe was 2 years plus. Since the car was never federalized and properly tested the car is not eligible to be imported under the regular import rules. With the special exemption any buyer will have to verify that the car is not being driven for more than 2500 Miles per year. The car is considered a historical significant car.

BMW Sauber F1 Team - Jerez Days 2 and 3

March 3rd, 2009

The track was wet throughout march 2nd, so Robert Kubica focussed mainly on setup training.  They were, however, able to collect the first data feedback for the BMW Sauber F1 car in the wet, so this was valuable.

By March 3rd, the track had started to dry out.  In the morning it was still damp, so Kubica was back at the set-up work with the BMW Sauber F1.09 running on wet tires.  They took a lunch break and continued the program development on a dry track.  The main focus of the track day was evaluating different solutions for the car’s aerodynamic set ups.  Kubica was able to complete 98 laps during the day, even though a faulty engine sensor paused them mid-afternoon.

“Overall it was a good day”, Kubica said after completing his third day of testing in Jerez. “We were able to make up some of the time we lost yesterday when rain meant we had to change our schedule. I started on extreme wet tyres, changed to wet tyres and finally drove slick tyres. Together with the various different set-up solutions I tried that helped me get an even better feeling for the car.”

BMW Sauber F1 - Jerez Day One

March 1st, 2009

The BMW Sauber F1 team was at it again in the south of Spain today, crushing the test track with their Sauber F1 car.  They were testing out the new Bridgestone tires that were built to 2010 specs.  The BMW Sauber team will be giving feedback to Bridgestone on how to improve the tire’s handling capabilities.  Robert Kubica lapped the 4 and a half KM Jerez Race Track 47 times, but the day was cut short because a wave of drizzle rolled in.  The team swapped out to  rain tires and began simulating race starts.

Some early-morning engine changes were made as a precautionary measure because the engine sensors were firing, but there weren’t any problems throughout the day.

Several red flags interrupted racing during the day, Robert Kubica mentioned that he expects a busy 2nd day.
