USAC AND IMRA MIDGET SERIES JOIN FORCES FOR 2016 SEASON

*

The United States Auto Club (USAC) and the Engler Illinois Midget Racing Association (IMRA) have teamed up for the 2016 racing season to form one of the biggest production engine midget racing series in the Midwest.

*

The season consists of a 27-race schedule with the majority of the races split between two “home tracks” in Illinois and Iowa: Spoon River Speedway in Canton, Illinois and 34 Raceway in Burlington Iowa.* The season opening event takes place Saturday, April 9 at 34 Raceway with the season concluding at Spoon River on Saturday, September 24.

*

The series will also hold its first ever USAC/IMRA “Summer Sizzle Speedweek” July 21-24, kicking off the week with a two-day event at Farmer City Raceway on Thursday, July 21 and Friday, July 22 for the "Engler USAC/IMRA Nationals.” *The series will then move to 34 Raceway on Saturday, July 23rd and conclude on Sunday night, July 24th at Spoon River Speedway.* Special events have also been schedule throughout the season to bring several high-paying events including a $1500-to-win event at the end of the 2016 season.

*

IMRA has consistently gained participation with the relatively stock-based, 2.4-liter engine platform, thus eliminating the cost of high-dollar aftermarket parts and creating one of the most affordable grassroots midget racing series.* IMRA has seen steady growth over the last three years with more than 45 drivers competing in the series in 2015.

*

“This was a perfect fit for our series and our drivers," stated IMRA president Tracy Hull.* “What a huge boost for our series!”

*

Furthermore, the 2016 USAC IMRA champion will be honored at December’s USAC banquet in Indianapolis.

*

“What an honor it will be to have the USAC/IMRA Midget champion enter the USAC record books alongside some of the greatest open wheel drivers in history,” Hull said. *“We could not be happier with our decision to create an alliance with USAC and we are honored to be included.”

*

What is the payout for these races?

[jdull99]

How about the rules? I'm trying to not spend as much time on FB as it would take to find them...can someone please post them?

[speedee24]

Any engines not covered by the preceding specifications must be submitted, in writing, for approval prior to entering competition.
Fuel
Pure methanol with no additives (top lube is ok) is required for all driveshaft driven cars. Methanol or gasoline is allowed for chain driven cars. No additives are allowed (top lube ok), including but not limited to, acetone, nitromethane, nitropropane, nitrous oxide, propylene oxide or any other oxygenating agents.

Jason

Tim Engler is a sponsor of the series. The question that any racer should ask them selves before getting involved in any type of racing is: "Just how much money am I willing and capable of investing in my race program to loose money on every race.

Racing is a very poor business to get into if you want to make any money. If not for sponsors in the Mega bucks department even the NASCAR guys couldn't make it just on what they won. If you own a prosperous business and like racing>>Racing is a very good way to spend your adverting dollars and all the time enjoy spending them. Or you can send money to some TV or Radio station or Uncle Sam, that is the question you need to ask.

Most guys running the auto engines will need some form of fuel injection and Engler has a lot of knowledge and experience building them.

Even with the one time expense of injectors and other addons this will still be hands down the most inexpensive form of open wheel racing out there including "Go Karts".
