For those curious about tech at the Championship Race, here is what was done:
Top 6 cars:
- Dyno & test for altered ECU
- Weights & plates
- alternator voltage (WOT)
- Fuel
- track width
- final drive ratio
- magnet on drive axle
- measure exhaust
- diff bushing
- weigh wheels
- tap on axles (check if hollow)
Top 5 cars:
- inspect cam sprocket timing
- whistle test
- remove exhaust - pay attention to downpipes heat shield. suspect some people are reshaping downpipes and putting heat shield back on
Top 3 Cars:
- flywheel assembly weight
- intake manifold - weigh, measure, inspect walls including thickness
- Remove Head, valves, springs
- inspect head gasket
- weight and inspect valves - compare to OEM valves brought (back cutting, etc)
- length and weight of valve spring
- measure valve unshrouding
- inspect intake and exhaust ports. check for excessive shooting of short turn radius at plunge cut
- cylinder bore
- remove cams and measure profile, check for coating
- remove and inspect intake and exhaust manifolds
- inspect for porting or other alterations
- if VVT, open the intake manifold and verify everything is operational
