Brian Shaw wins DuQuoin mods

I was watching the silver crown cars on the back straightaway a couple of years ago, and most were in the 140 - 142mph range at the back gate right before they let off-- with a radar gun.. one car ran 143 a few laps, I didn't get to see what the mods were running, though. I think schrader would have qualified mid pack in the crown cars this year with his qualifying run. way heavier car and small tires,,, that's getting it done for sure

I'm not so sure I buy the big engine is rougher on the engine idea when it comes to dirt racing. A few years ago I put a data logger on a sportsman car at Montgomery County Speedway and when the track was heavy and fast RPM didn't vary by more than a few hundred all the way around the track. How would it be any different?

40 miles/laps of racing on a mile vs 5 miles/20 laps of racing on a ¼ mile track. Plus the duration you run at full throttle/max RPM's on a mile. Your on the gas much longer on a mile than on a smaller track. Running 40 laps on the mile is like 8 or more full regular nights. On the Hammerle trio or cars, the Belleville motor can go 2 full seasons, all the other motors (highland and granite cars) get freshened every year.

I don't see how it's possible that you're on the gas for a longer period of time really. I was astounded to look at the data and see that the driver was only off the throttle about 1/5th of a second two times each lap when the car was "set" for the corner. The rest of the time it was basically wide open.

Since the car is going much faster wouldn't 20 laps on a 1/4 mile take longer to run than 5 laps on a mile? I would think so.

I can only tell you what a man with over 40 years of racing experience said to me....Bigger tracks are harder on motors. Seems like common sense to me.

Our motor wasn't a low budget motor had a rod bolt break in a new set of callies rods but I think the big reason they don't draw is risk of everything motor,car, and health it's no joke runnin there!

Sorry about that didn't mean low budget motor was just stating you lost your engine which really hurts.

The V10 Ford in our motor home has turned more RPM's than any of the trio of engines in the the 16H stable. That guy is SLOW! , but easy on motors. LOL
