*j-six, makupad sya in the sense na mabagal sa arangkada!! you have to rev the engine higher if you want speed and power that is what i mean na MAKUPAD...have you checked your speedometer?? max speed for most suzuki vans is 120kph to 140kph!! Stock engine suzuki F6a, or F5, for these kei class vans were built with a LOW gear transmission to compensate for the small engine.. i'm saying this because i also have a suzuki van..and yes it can go 120kph but at what rpm?? its almost 6000rpm!!! while in my kia carens i can do 160kph at less than 4000rpm.. engine at that rpm is stressed and can be a cause for early wear and tear of engine parts..

suzuki vans in the video you posted were modified and enhanced to do drift and race.

if you see kevin3000 speedometer 120kph is max speed.. how long can you maintain that speed?? sadly he doesn't have a tachometer to gauge engine RPM but im sure its already at 6000RPM or more..

these vans can be used in highways since minimum speed is 60kph and max speed is 80kph - 100kph.. i've tried it at NLEX when we went to bulacan with 5people on board i try to drive the van at 100kph at 5000rpm it was stable on the road but you can hear the engine under stress i hold it for 10 mins and slow down again to 80kph

makupad talaga suzuki sa highways especially when overtaking long vehicles like bus and trailer trucks..but it can do the max speed if you want...
