VHM exhaust port flow measurement with VHM's top flat radius and 4° pistons

Complete list of all VHM pistons: http://www.vhm.nl/VHMpistons In this video we show how we measure the exhaust port flow, with in this case a TM KZ10B Cylinder for karting. We show the difference of the exhaust port flow between VHM's four degree piston and VHM's flat piston. The value of the exhaust port flow is larger with the flat then with the four degree piston. The flat piston has about 2% more exhaust port flow. The tool we use to attach the cylinder and piston onto the flow meter is designed and build by ourself. 00:05 Measuring the exhaust port flow with VHM's 4° piston and VHM's top flat radius piston. We will show the difference between the two. 00:14 Test 1 is with VHM's 4° piston 00:21 For the exhaust port flow measurement we have build our own tool for attaching the chosen cylinder and piston onto the flow meter. 00:59 Setting the piston at a vast height, just beneath the exhaust port 01:08 When the piston height is fixed, the digital degree meter is set to zero. Then we turn the crankshaft for example 27° down. 01:23 The flow meter shows a value for the exhaust port flow of 42.2 with the 4° piston and the crankshaft at 27° 01:50 The flow meter shows a value for the exhaust port flow of 12.5 with the 4° piston and the crankshaft at 8° 01:59 Test 2 is with VHM's top flat radius piston 02:17 Setting the top flat radius piston at the same height as with the 4° piston 02:42 The flow meter shows a value for the exhaust port flow of 43.2 with the top flat radius piston and the crankshaft at 27° 03:11 The flow meter shows a value for the exhaust port flow of 12.9 with the top flat radius piston and the crankshaft at 8° _____________________________________________________________________________________ In deze video laten we zien hoe we de uitlaatpoort flow meten, in dit geval van een TM KZ10B cilinder. We laten het verschil zien in flow van onze VHM 4 graden en vlakke zuiger.
