Make Way for the Pony Express

Today we’ve got a guest blog by a group guys who are die-hard racers. It’s a bit long, but it’s a very interesting read about doing much with very little, and the adventures involved in budget racing. Without further ado, I give you… Team Pony Express!

Team Pony Express is a group of friends who have gotten together to build a crapcan race car. Our steed? A 1991 Ford Escort. But not just any Ford Escort – this is the Pony edition, in which Ford did Colin Chapman proud and “added lightness.” They took out the radio, removed the power steering, and allow all 88 churning hamsters of the 1.9 liter four to do their work on the remaining 2,491 lbs. In short, it’s the GT3 RS of Ford Escorts, but Ford made the very un-Porsche-like decision to charge less for it.

Our particular car was once Aaron’s treasured turbocharged beast, but blew the diff out the side of the transmission housing and the poor Pony was left to collect moss in the yard.

We watched in envy as the rest of the country got to enjoy the crapcantastic 24 Hours of LeMons, and we lamented the fact that the closest they came to us in the Pacific Northwest was the Arse-Freeze-a-Palooza at Thunderhill in California. Then, last Halloween, we saw the light: a new series, the ChumpCar World Series, with more or less the same rules! And they would have TWO races in our neck of the woods! We started putting a team together from the ranks of our Subaru-driving brethren, and began the search for a car. After scouring Craigslist and eBay for a while, we realized an ideal first race-car was right in our back yard. Or more specifically, in Aaron’s back yard, aka the Pony Corral.

Our team consists of Aaron, the Pony Corral Proprietor; Kyle, our crew chief and resident Escort expert; David, the team photographer; Tommy, who’s in charge of our torpedoes when he’s not autocrossing; Ryan, a pro at removing sound-deadening material while everyone else eats and drinks beer; Nate, Destroyer of Clutches; Nick, finder of all things free; and myself, Zach. I’m writing this blog, I guess.


Our motley crew

Out of this motley crew, Team Pony Express was born. Our first workdays involved removing the engine and transmission and tearing out all the unnecessary interior bits in the Pony. We unbolted and ripped out seats, dashboard, and interior trim, then attacked the sound-deadening with a hammer and dry ice. It took hours of work, but eventually we transformed a fully functional street car into a gutted, engine-less hulk.


The newly gutted Pony

After examining the suspension and brakes, we decided it would be a good idea to get some spare parts. Our Escort experts mentioned that the Escort wagons had larger rear drum brakes, so we sought out a wagon for a parts car. We found a running example in Seattle for $200, and Aaron brought it back to the Corral. We descended on the car like a plague of metal-munching locusts, and removed the front and rear suspension and brakes, as well as the motor. Then we thoroughly vandalized the car and put it on the street for the hulk hauler to take away.

Next order of business was to seam weld the car, install the brakes from the wagon, and install the larger 13.2-gallon Escort GT fuel tank we’d acquired from the junkyard. We had a 2.0L SOHC motor from a 2002 Ford Escort, so we swapped over the accessories from the 1.9L, hooked up the 5-speed, and slid it into the car. We ordered a roll cage and welded it into the car. We relocated the battery to a sealed box in the passenger compartment, and added an extra pair of tail lights in the rear hatch area. Then, we thought, we were ready to start the car.

While all of this work took place we lost our shifter bushings. Knowing that the OEM 20 year old bushings would still be sloppy if we did find them we got in contact with Corksport and got our hands on a set of Bronze Oil Bushings. What a difference! The shifts are much more accurate and smooth. They will also take the abuse that we are going to be giving them at the race track.

We were wrong. The fuel pump whirred, and the starter turned, but the engine never caught, and the garage was filled with the pungent aroma of gasoline. Apparently the heat of welding the cage in had melted the plastic fuel lines! Another junkyard run was in order. We also wanted to upgrade the Pony’s stock headlights to some brighter HIDs, but didn’t want to be the obnoxious guys running HIDs in stock reflector housings. Luckily I had my stock Legacy projector units sitting at home in the garage. They’ll accept an H7 HID retrofit, and we’ll get a much better pattern than the Pony’s reflectors. After JB welding them into place in the Pony housings, we’ve got much better output.


Super night-vision mode

Having upgraded the headlights and installed the new fuel lines, we were set to fire up the Pony. The kill switch and gauges were set, the electrical systems seemed to work, and we turned the ignition. It caught the first time, fired up, and settled into an awesome-sounding lumpy idle. After a few seconds of running, Aaron said, “I’ll try the kill switch!” He flipped it off…and the motor skipped a beat and kept on going. Uh oh. He turned the ignition off, and that killed it. Then we noticed that some of the alternator wiring had melted. The electrical boys were back to work, and thought they had it figured out. The wiring problem, yes. The kill switch, not so much.

Our next workday saw the tires, Dunlop Direzza DZ101s, installed on the car on our gorgeous Acura “Fat Five” wheels ($100 on Craigslist). We’re hoping the DZ101s will hold up well in the cold and potentially wet weather we expect in Portland. We also bled the brakes, worked on some of our secret underbody aero, finished the majority of the wiring, mounted the OEM gauge cluster, installed our custom “cram air” scoop and sheetmetal airbox, and labeled the switches on our beautiful wood control panel.


Our magnificent switch panel

By late September, the car had made a few shakedown runs on the road, and we decided to give it a real challenge. Five of our seven drivers accompanied the Pony to Pacific Grand Prix, just outside Pacific Raceways, for a full day of lapping on the .8 mile outdoor kart track. We shared the track with all kinds of high-performance cars, including a Lamborghini Gallardo and an Ariel Atom, and in total we racked up almost 3 hours of track time. The Pony was a hoot to thrash around PGP, even playfully kicking up a wheel going around some of the corners, though we did a number on the front Dunlops. The only issue with the car was a slow oil leak from the dipstick tube, which we stopped with…paper towels. Hey, it worked for the day!

Through all of this, our steed was looking a bit…bland, clad as she was in her original white. One of our final work days remedied this, as we busted out the rollers and painted on a pair of blue and red racing stripes and some postal barcodes on the hood and the side skirts. We also finished painting the car’s interior, painted our “inner body aero,” replaced a stub axle that had a torn boot, cleaned the MAF and IAT sensors, gapped the spark plugs, fixed the dipstick leak, adjusted a sticky rear brake, added a volt meter, cleaned up the wiring for the instrument panel, and made sure the defroster would run all of the HVAC system’s hot air into the windshield.

Finally, a few weeks later, we had our final workday, where we added our awesome enormous vinyl pony graphics and numbers, retouched some paint, and fashioned some very high-tech funnel-and-dryer vent brake ducts. After we finished work on the car, the drivers suited up in their full race gear and we spent nearly an hour practicing pit stops, with each team member rotating through driving, fueling, holding the extinguisher, windshield washing, and assisting the driver change. We had our stops down to under 3:30, which is perfect since ChumpCar rules require that we stop for 5 minutes if we add fuel to the car.

One last “mini” build day saw the Pony gain some LEDs in the wheel wells; a fresh air tube for the driver; the last bits of vinyl on the roof and hood; cornering lights; and a one-inch raise in ride height (achieved by adding washers to the top of the struts, above the springs), which should improve the suspension geometry.


Freshest… Air… Ever…

Our big day is only days away, and the ChumpCar field had better watch out – we may not have the fastest car in the field, but we’re sure as hell gunning for the engineering and theme prizes! We’ll be racing for 18 hours in Portland, OR at Portland international Raceway’s 2 mile road course.

CorkSport – Not Just for Your Mazda Anymore

Being that I usually post about new parts coming out, I thought I would change it up a little and blog about something different. We are finally rolling out some SWAG with our new logo on it here at CorkSport and one of my favorites is the slap-on can koozie. It features our new logo screen printed on a fabric layered over neoprene. It also utilizes two of the old slap bracelets that some of you may remember, so it will fit various sizes of cans and bottles. However, it does not come with installation instructions or telephone technical support.

Being an engineer, I tried to come up with a way to still get some useful data out of this post. I came up with a comparison of two typical domestic beers straight out of the fridge: one in our new can koozie and one without. The picture below shows my two test victims (opened to simulate someone who is actually drinking a beer).

For four hours, I took temperature readings of each beer every 15 minutes. The ambient temperature in my office was about 73 degrees F and the fridge remains roughly constant at 38 degrees. As you can see, both beers start out at 38 degrees (the temperature of the fridge) and remain fairly similar to one another for the first hour. However, from hours 1-4, the can in the koozie stayed roughly 7-9 degrees cooler. This may not sound like a lot, but you have to take into account that it also keeps your hand from warming up the beer as well (I did not test for that, but it may be a good excuse to retest).

In the end, the CorkSport slap-on can koozie did its job and I had an excuse to drink beer at work, albeit 71.3 & 63.9 degree beer after staring at untouched open beers for four hours.

We also have our new T-shirts available!

Introducing the XCorder (More Like XTREME-Corder, Am I Right?!)

We recently added a new part to our webpage, the Xcorder. I had a chance to drive around with one for a few weeks getting more familiar with the unit.

The primary feature is the video capture. The camera is always running on the unit and the videos get saved in 1 minute chunks in an MP4 format. The wide angle lens does a really good job of showing everything in front of recorder. You can see the complete windshield the Xcorder’s entire view.

I got a chance to test out the load sensor in the Xcorder doing product testing. I took the Xcorder out for a spin in the Mazda 2 with a new rear bar to get an idea of how many g’s I could pull around a roundy-round intersection. In the video below you can see the path I was taking and the g-load spikes. I came close to pulling 1 g around the turn which is shown just under the video screen (the spikes on the x-axis). You also get a good look at where I was doing said suspension testing in Vancouver with the GPS location. After recording the video I noticed that I slowed down going around the corner. I did not want to slow down; my sub-conscience took over while driving. This will give me something to check while competing in the next auto-x. If I can correct a throttle lift at points on the course where I need to be on the throttle it can result in quicker times.

If you really want to amuse yourself with the Xcorder turn it around backwards so you can see the expressions of the drivers and passengers. You would get a wide angle view of everyone and their faces while driving. (check out those white knuckles on Jake)

If you have kids it also gives you a great deterrent against the sibling “she said he said” conflicts that can occur in the back seats.

Getting the videos off the unit is really a snap. The SD memory card pops out of the side which is super handy. The video and picture above, I pulled off the SD card on my laptop in a few minutes.

Is it worth the $199? You bet it is. The little bit of data- logging information I gains from looking at my driving in the corner testing out the g loads is something I had no idea I was doing. That little piece of information is worth it in competition events. The extra insurance the Xcorder offers makes an incredible value. Having a constantly running video recording can be invaluable. I hope I never have to pull a video off of the unit to prove who caused a traffic accident.

Hydrolock

After seeing several forum posts and receiving many emails asking about performance intakes and sucking in water I decided to write this bog, because I wanted to get this cleared up for everyone with questions.

Water is everywhere, as our planet is covered in it. There is water in the air. When you are driving your car down the road you are sucking in water. It may be water vapor but it is still water and harmless to your engine.

Open element filters in either short ram intakes or cold air intakes have water come in contact with them by splashing puddles or rain. With air passing through the filter the water gets vaporized (evaporates) and gets consumed by the engine during the combustion process. This process is like the hand dryers in a washroom that blow air across your hands to dry them. The water enters your intake as vapor which is safe for your engine.

There are several companies that sell water injection systems for combustion engines. The water cools the fuel air mixture resulting in less chance for engine detonation. This is helpful for forced induction engines running higher boost levels to control detonation and get more power.

The only time you will experience water damage/engine destruction is when the intake in your car creates a seal with a water source, as in complete submersion. The engine creates suction from the air pumping movement thus pulling more water into the intake towards the engine. This becomes a problem when the water gets to the cylinders and the crankshaft tries to move the piston up. Water does not compress like air and causes the piston to stop and catastrophe occurs. This is called hydro-lock, which is when the cylinder is too full of water and the piston moves against it effectively preventing, or “locking” the engine from further movement. The result of hydro-lock is bent connecting rods, broken pistons, etc. It is not pretty.


Hydrolock Damage

Cold air intakes normally get the bad rap for sucking up water and hydro-locking engines. You would have to move your vehicle into large water mass, like a very deep puddle and submerge your air filter for this to occur. If you live in a climate that has lots of standing water or floods on a regular basis a cold air intake is probably not the best choice. Short ram intakes normally have the filter situated up higher in the engine bay near the throttle body. The chances of water being deep enough to cause a seal and suck in water are pretty low. You would need the water to be higher that the filter location in the engine bay. This also applies to the stock intake airbox. If you see water cresting over the top of your hood you have more problems than water getting into your engine.


Sure fire defense against water in your intake

If you want an aftermarket intake and you are paranoid about hydro-locking your engine there is a solution. The sure fire way to avoid water getting into your engine is an intake snorkel. Most have the air pickup at the highest point on the vehicle to give you the best chance when fording a river.

The best advice I can give is to steer clear of deep standing water if you have a performance intake installed in your Mazda. If you are not sure how deep the puddle or standing water is go around it.

CorkSport Grand Prix

A couple weekends ago CorkSport held an impromptu Mazda competition at the last SCCA event this year in Portland, OR. A few of the guys from MazdasNW.com showed up to come have some fun with us in the Pacific Northwest sun (Rain). There were quite a few large puddles out there as Travis found:

We had two classes to compete in, Turbo Class and N/A Class. The weather made it difficult for any racers to turn in good lap times, and the MazdaSpeed3s were having the most trouble out there trying to turn in anything resembling a decent lap time. With the course set up the way it was they were not able to get out of 2nd gear and had too much power to put to use on the very wet track. Marty Chen in his Speed3 managed to keep it together for the win in the Turbo category with a time of 50.94.

Erik Getty got to run his Miata in the first run group before it started to pour down rain and turned in a time of 48.07 giving him the win for the N/A class.

Congrats to Marty and Eric, and thank you to everyone that came out and I hope we can do this again next year!
