I made $ drag racing my stock 3 cylinder Geo! Long!
 
They held Import Day at Edgewater drag strip near Cincinnati Sunday and unlike the vast majority of tracks that allow domestic compacts in they stick to a imports only rule. Sooooo I drove the 96 Geo Metro 1 liter down there. I was worried that it would not run quick enough since nearly all tracks have a 19.99 second rule for your time in competition. I had a tach put in Tuesday to help for this day and found that on the street when I thought I was winding it tight I was in reality shifting at only 4000 rpm! I drove it down there with the gas that was already in the tank so I would not be carring extra wt of uneeded fuel. I weighed the car after every pass too. When full of gas it is 1730 lbs (I have taken 70 lbs out of it)....but Sunday I also took out the baby seat, his toys, his bag, the spare and jack for a car wt of only 1660 lbs! The gas gauge read a bit over the red mark so I still had enough gas for the mission. I put 11 practice passes on it and 4 more rounds of eliminations....the car did not use but 5 lbs of fuel during the event and the 80 miles of in town driving with another 115 miles of interstate and a total of 15 full out passes on the track gave me my worst FE ever of only 37.1 mpg.

The 1st pass I side stepped the clutch at @ 2000 rpm like I do on the street (at 1500) and shifted at 5000 rpm....my slowest pass of the day...a not good enough 20.23 at a mind bending 64.71 mph:mad: and once into 3rd gear before half track it seemed so far and slow to the end! The 18th mile was a 12.809 at 53.65 mph. From there on I experimented with different ways to launch and shift points. The 2nd pass while shifting at 5500 found this thing a blur at 19.838 and 67.51 mph while also launching at 2500 rpm and getting a bit of tire spin!!! I found that only with some tire spin and shifting at 5500 rpm could I stay in the 19s. The best pass was a 19.687 at 68.00 mph while not shifting into 4th and crossing the finish line at 5700 rpm. The 4th gear shift was alway at the mph recording light, 90 ft from the finish line.

I found that the car ran the most consistant times when leaving with some tire spin and shifting at 5500 on all shifts but the 4th gear one I was now doing at 5250, a few feet before the mph timer lights. Driving this way on my last 7 practice passes and 4 rounds of eliminations it ran between 19.842 and 19.995.....I dialed a 19.90 for the race. My 12 second SRT4 varies by only .14 pass to pass so this was quite acceptable while the 17 second Horizon I race varies by .06 at the most.

My average reaction time in practice was a .061 (.000 is perfect) while my best was a great .013 (I try for a .020-.040) and in eliminations they averaged a .066....not too great, but compared to my competition, darn good. In practice my opponents had a best of .101 and the worst of .727 then in the 1st three rounds of eliinations they had easy to beat .287, .303, and a .320. In the 4th round I beat myself by running .051 too fast against a plain jane 4 door accord that ran a 17.358 on a 17.35 dial and his RT was a .041 to my .061...I was on the brakes barely at the end and I beat him across the line by only .031.....I was okay with that because it is hard to judge finish line margins when there is a big mph difference.....in this case he was flying by me at 79.8 mph....the slowest car there but for me. Then I found out that he races there for pts every weekend with that car and his Super Pro car.

The quickest car I ran went 10.948 at 130+ while most ran 12.20s - 14.60s.

Oh yeah, the $250 did not hurt either...now I know I have a capable spare if my 12 second car is down!:thumbup:

That's awesome.

I should have tried to bracket race at some point. The car I would take had a spread of like 8 thousandths of a second over 3 different trips to the strip!

Hahaha... did you bring a thermos so you could sip some tea between shifts? Nicely done, bringing home the money in the slowest car I could possibly think of.

There is not much time for the1-2 shift at the 60' mark (@ 2.8 seconds) a little more for 2-3 shift at the 330' mark (@ 8.1 seconds) but tons for the 3-4at the 1230' (@ 19.8 seconds).

One of the spectators drove in with a new Smart car and was bragging about his better than EPA FE of 45 mpg.....I showed him my log book that had only 2 long trips of under 50 mpg and he kind of turned real quiet and pale while he just spent nearly $20K on something that got worse FE than a 12 year old, $3000 car that has room for 2 kids too.

That's great, ATaylor! It reminds me when I lived in Indianapolis (~5yrs ago) and was attending Lincoln Tech. We had a field trip to Raceway park and all the guys wanted me to run my Metro down the strip for fun. I was thinking seriously about it, but decided not to, since I couldn't afford to break anything at that stage in my life. Knowing what I know now, I wouldn't hesitate!

LOL I love that story. I bet it killed the 10 sec car waiting at the line for 10 seconds till his light came.

I had a 93 ford lightning that was an awesome bracket racer. Foot to the floor, no tirespin, auto tranny, consistant within 3 to 5 hundreths. It was fun. And got 14 mpg no matter how you drove it. LOL.

I ran my festy a few weeks back, best was 17.95 at 76.1mph. Bone stock.... well minus the cat...

A lady that flew in with her husband for the Shelby/Dodge Natls had NEVER drag raced in her life. They rented a 3.5 V6 Chrysler 300 (BIG) and she won the entire event! The car never varried over .01 and her husband taught her well on the launch! That was in 2007.

Yep, if you never red light you are pretty much golden. As long as your reaction time does not look like this --> :turtle:

That's a great story Angelo!

Forget leaving on the third one, you practically need to leave on the first yellow with a car that slow! haha

The import only events in Sacramento and Bakersfield used to be pretty easy pickins because none of the street racer Honda guys could cut lights (combination of inexperience and fwd with wheel spin on a bald starting line... ) Most of those kids who stuck with it have gotten a lot more savvy on the tree these days.

I once used a friends all stock '79 VW convertible as a 'back up' when my race car broke... I was dialing 19.50ish as I recall :turtle:

I had no tach in that car so I used some strips of blue tape on the speedometer so I could at least shift at a consistant mph. Like you said, I found it real hard to race the top end with such a big difference in speeds.

one serious question; Where did you find a tach that reads 3 pulses per 2 rpm (3 cylinder)? My 3cyl. Metro needs one
