Is POWRI going to run the D2 series this year? Or USAC IMRA? Have not seen any schedules

I thought I saw a PowrI D2 schedule. Maybe not. Either way, too many D2 series, not enough cars.

Looks like IMRA's for sure about every other week at Spoon River and six or so races at Quincy. They've said there are other tracks in the works.

Their Facebook page says stay tuned for info about the "1st Annual USAC/IMRA Midget Nationals."

Sycamore Speedway released their schedule, has 4 Powri D2 shows on it.

Re: D2
 

Isnt Southern States Midgets, D2? They are Powri...

Re: D2
 

Doesn't say D2, but I think we all know it is...(& I know the link says 2017, but the headline says 2018). Interesting how we are relying on a "stock car track"'s website for these schedules; I gotta say...lol. It wasn't too long ago there was not one consideration of anything to do with open wheel racing, of any sort, at this track - but they have gone thru management changes of recent...times do change (plus there is a difference in a "national" purse & a "non" national purse too...)

Re: D2
 

Yes PowrI and IMRA/USAC are running D2. It is a great class. A lot of guys are moving up out of the class, so we need more guys coming into the class.

IMRA is supposed to release there schedule end of next week. Sounds like there is some exciting news for several big shows this year. Sound like Thunder Midget and Powri will also have a schedule along with several stand alone events including the up coming Gater Nationals in Florida first Of March...... Do a facebook search for information on all the groups listed above and individual track.

Total of 11 open wheel shows for 2018. Glad to see it!

Only 3 nights for speedweek.. Might need to reevaluate if it's worth the travel.

Badger engine rules now.

Re: D2
 

Really? How can there be a validation for 2 midget classes in the same sanctioning body then??? Running a stock block, head, & crankshaft (no matter what they came off of, just as long as they are OEM and = 2.4Ls) makes that much of a difference to people???

Bad move..Unless there is something that will restrict the Badger engines.in all fairness.. We should wait until the rules are released.

Look at the rules on badgers website and You will have powri’s d2 rules.

If it's those rules.. Cycle engines are screwed..
I wonder how many Powri D2 cars wanted to go to $15k engines

Why would they be screwed? they are mini sprints, there’s already been classes for those guys. They could run the Usac shows. As far as I know their rules haven’t changed.

Re: D2
 

I'm thinking they are already there, or real close, so are the Mini Sprints, if you want to really be in the hunt, JMHO! Bob

Re: D2
 

IMRA-legal Ecotecs have performed well in Badger shows, and in both IMRA and USAC MTM races it's always been a fair fight between the Chains and the Shafts; just because you "can" doesn't mean you "have to", and setup and skill are always premium assets...

Big difference from D2 (220hp)and Badger (350hp)

Re: D2
 

Yeah, and 2-liter Focus (Foci?) and 1000 CC Mini Sprints have run 3rd against National Midgets at Montpelier...

We ran third at Angell Park with a stock R1 against the Badger guys. My son came in and said "that's all she's got and then some".

Anytime a car can run that well against cars with 60% more HP.. Either the track was super slick.. Driver is Larson or Bell.. Or the other cars were awol.
For comparison 900hp 410s racing against 560hp..not many would tow their 560hp car to run against 900hp with nothing but hope for slick track conditions

I haven't kept up as much since getting out of midgets, but it seems like the current Badger engine is similar in power to what the -12 Gaerte motor was putting out about 10-15 years ago. Am I correct or are the numbers I have been reading exaggerated to make it sound that way? I remember the Dyno sheet from a Brayton Buick motor I had that was pretty competitive back in 2001 showed peak HP around 340. Are the current BMARA motors comparable to that? I know you can make a Dyno sheet show whatever you want it to, but realistically are the current motors right there for power? If so BMARA is far from a D2 organization.

Hopefully there will be enough gain in car counts that D2 can sustain there own series and schedules. The theory of stock engines and lower cost seems to be a great idea.BUT,you can't let others alter the engine rules and still call themselves D2.it'll be too confusing and unfair to the true D2.

Pepsi Nationals 2016 Badger ran their 20 lap feature before the Powri cars ran theirs. Track was good, groove was on the cushion, full field of cars. Mitchell Davis was the driver we ran third.Stock R1. We would make the trip up multiple times to race with them, we also would go to Montpelier to race with the higher horsepower cars. We would basically race anywhere they would let us run. Lack of horsepower never scared us off

Re: D2
 

Mitchell also ran as high as third in a "Montpelier Rules" race at Kokomo late in the year, driving an Ecotec I don't believe he'd ever sat in before. I think he ended up fifth overall and the highest non-National-engined car but he was harassing the heck out of the top 2 for a while. This was with an engine with a stock single throttle body manifold, that I'd never really seen do much in the hands of other drivers, more proof that skill and setup have as much to do with success as anything else. Mitchell's a heck of a shoe.

Re: D2
 

Badger Rules/Powri:

A. All engines must be inline, normally aspirated, internal combustion, four cycle, reciprocating piston type,
incorporating a maximum of four (4) cylinders. Engines must be a production engine from a passenger car and
reasonably available in the United States. These engines are allowed a maximum displacement of (146.457 CID)
and have no more than four (4) valves per cylinder. All production passenger car engines must use the OEM
block, OEM cylinder head, and OEM crankshaft combination from the same manufacturer.
B. The OEM block maybe machined or strengthened for longevity. Blocking and/or opening lubrication and coolant
passages will be allowed. The crankshaft may be balanced, and oil passages may be chamfered. Lightening,
chamfering or “knife edging” the crankshaft counterweights beyond minimal material removal for balancing is
NOT permitted. NO grinding on the crankshaft journals of any kind. Connecting rods, rod bolts, pistons, pins, and
piston rings may be replaced with aftermarket products. Titanium products are NOT allowed.
C. The OEM cylinder head maybe machined or strengthened for longevity. Porting of the cylinder head including
intake matching is NOT ALLOWED. Cylinder head ports must remain stock as cast. Machining, grinding,
sanding, or etching of the intake and/or exhaust ports are STRICTLY PROHIBITED. Camshafts, valve springs,
valve spring retainers, keepers, followers or rockers maybe replaced with aftermarket products. All timing
components such as cam gears, sprockets, timing chains, and timing belts maybe replaced with aftermarket
products. Titanium products are NOT allowed except for valve spring retainers.
D. The fuel injection system is open to either mechanical or electronic. Variable valve timing (VVT, VTEC, etc) is
allowed on cars using the stock OEM intake manifold and throttle body. Cars utilizing any fuel injection system
other than the stock OEM intake manifold and throttle body must have variable valve timing disabled or in a fixed
position.

Somebody/Anybody with a couple $ needs to pick this kid up! He is a star waiting to happen!

P.S.: Chase Mcderand (sp?) is another that needs a serious look too.

Now back to your regularly scheduled thread. 😊

Re: D2
 

You will also want to pay attention to the the ignition rules from Badger as well. I pasted them below. Would hate to see someone build something and not be legal.

A. All cars must have an ignition switch or emergency shut off within easy reach of the driver and labeled "on/off".

B. The use of electronic logic processors to continuously store data from any function of the racecar is strictly
prohibited. (Note this rule does not include electronic tachometers).

C. Any form of traction control is strictly prohibited

D. Only the MSD 6214 Midget ignition, the Electromotive TECs, Electromotive XDI, IG Controller and PE3
ignition boxes will be allowed.

E. Ignition systems must be submitted in writing and pre-approved by BMARA on a TRIAL basis before being
allowed in competition. All trials approved for temporary competition will be posted at the drivers meeting.

Re: D2
 

Badger definitely is not a D2 series. They never intended to be, and their members will quickly correct you if you mistakenly refer to them as D2. Another series copying their engine rules does not change what Badger is.

I believe you are absolutely correct. I think if they could get peak HP up to around the 340-350 mark by doing something to the rules without really increasing costs too much you would see racing back to how it used to be. For me the current cars look to be lacking just a little bit of power especially when there is a cushion to run on.

Re: D2
 

I would argue that Badger is there now. They don't have the peak HP of a Toyota, SR-11 or Esslinger BB7. However, that was never the intention of the rules anyway. The intention was to be fast enough to keep the fans entertained while also reducing cost to a range acceptable for the average or regional racer. The cost came in right about where people expected ($15K new which is the same as a new top of the line D2 engine) and the speed exceeded expectations.

The engines do not make as much overall HP but they are extremely drivable which allows them to turn some fast laps. The Badger guys turn Angell Park at around 14.9-15.0 today. When Badger ran head to head with POWRI National at the Pepsi Nationals the fastest lap turned in the feature was by Andrew Felker at a 15.449 with the best Badger car at a 15.659. Two Badger cars were in the top 11 for feature lap times. So they can turn quick laps. Where they suffer is when you lose momentum. When you make a mistake with a Badger engine it costs you far more than if you had a purpose built engine.

One thing people don't realize is that the Toyotas, SR-11s and Esslinger BB7s are running 161 to 166 CID and the Badger engines are only at 146 CID. The architecture of a Badger engine doesn't allow them to get to those cubic inch sizes. The Badger engine program has been extremely successful and it will only get better as more teams come on board.

Edit: I should also mention the Badger weight rule is 1100lbs with driver to eliminate the advantage of carbon fiber and titanium, whereas USAC is 1035lbs and POWRI is 1050lbs with driver. So Badger has not only tried to reduce cost on engines but on cars as well. If Badger cars were down at the USAC and POWRI weights that 14.9-15.0 would certainly be quicker.

I'm close to agreeing with you, but I think where BMARA is lacking just a little bit right now is the same as where you mentioned. The momentum issue is where I notice the biggest difference. I don't think Badger needs to have HP numbers coming close to the Toyota, SR11, or other super high dollar motors, but if they could bring them in just a bit more to make running a heavy cushion a bit more manageable, I think the on track product would benefit greatly and bring even more growth to the group. I don't know that it is practical with the current platform in that the displacement is limited by the stock block, but maybe there is a way without going "dollar crazy" again. I think the $15,000 top end new motor price is about as high as you can go to keep the series growing and it is admirable that the organization has been able to accomplish what they have so far. I just miss seeing the ability to bang off of a heavy cushion without such a lag in getting back to speed. Maybe a few year's development is all it will take to find that little extra power needed to get it done.

Re: D2
 

I have a question, about an engine I considered to start with, then found it had been removed from the legal engine list, I have asked many times, with no answer in most cases, or any reason either. The engine in question is the 2.0L Mitsubishi, Neon, 420a, Chrysler engine, what is the issue with using this engine, it is very available, and AM parts are plenty available, just curious. Thanks! Bob

Is there a shortage of current motors listed? I would say the powers that be were originally trying to keep the rules and tech simple by allowing each 2.4 manufacturers to have a motor. More brands and generations of brands make it more difficult to police. JMO

Re: D2
 

No.... LOSS Midget are not POWRi

Re: D2
 

https://youtu.be/YbiqX5TRnY0

Check out the first half of this feature from 2016. This is me and Gage Walker going at it running the cushion. Later you see Brandon Waelti and Walker going at it a bit. I think this tells most people everything they need to know about how good the Badger engine program will be when its at its full potential. Also I was in a Honda and Walker in a Ford. Waelti had a Ford as well.

Re: D2
 

If anyone would like to see a quick, clear and concise set of rules for the production based Midget engine rules I invite you to visit http://www.2-4midgetracing.com

These are NOT D2 rules. These are the Badger style rules. If anyone is interested in working together to implement a program like Badger's into their series please feel free to use these rules. These are 15 easy to understand rules that can quickly be placed into a rule book. All I ask is if you do use them do not alter them without contacting me. Thanks.

In case anyone is wondering, I wrote the rules for the IMRA in winter of 2013 that were used in 2014 and 2015 (before they changed to D2 in 2016). Those rules were the basis for the Badger rules that the Badger teams later implemented in their own way through a vote by their car owner members. So the rules on the 2-4midgetracing.com web site are an evolution of the original IMRA rules.

These rules were based off of the Chevy II engine my family built in 1973 but with updates for today's technology and engine design. The main goals were to reduce cost significantly without hindering the speed, ingenuity and creativity that Midget racing is known for. If you believe in all that and I can help you in any way please feel free to contact me.

Re: D2
 

2. All engines must use an original manufacturer’s OEM engine block, OEM cylinder head and OEM crankshaft. Engine blocks, cylinder heads and crankshafts must be from the same OEM manufacturer.

Does this mean it has to match block to head to crank as it came from manufacture 2.4/2.4/2.4 or as long as it is OEM GM...OEM Ford ect.... as in a 2.4 block Ecotec with a 2.2 Ecotec head with a 2.0 Ecotec crankshaft...all GM buy 3 different engines? please clarify
