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.
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.
