If you wondered what a driver has to go through to coax a fast lap out of a Pro Class car at the WTAC in Eastern Creek, this in-car video of Under Suzuki will give you a good idea. This shows his fastest lap at the event, a 1'31"456. The camera and telemetry system was set up by Orikoshi-san, owner of one of the Exceed Moat S14s. Too bad the boost levels are censured out!

Holy crap. That car can pull 1 G just from acceleration alone. That's impressive.

Look at that steeringwheel shaking on the corners!

What wonders me is that the driver is not able to dose the throttle in the corners. it's all out on the straight but the turbo kicks in so hard you can't do anything else than brake the car into the corner and let it roll through.





Key to a quick corner is to brake on the last straight before the corner, turn in and let it follow throuh by using the throttle...

The boost level can be approximated by watching the fuel pressure. Static fuel pressure on most turbo cars is ~43psi. The fuel pressure is in bar, which can be converted to psi by multiplying by 14.7.Subtract 43 psi from this figure and you get a rough idea of what boost is being run. In this is case it appears to be ~30psi.

do he use the cluch while shifing in sequential ?

Holey mis shift batman, 9000+rpm, yummy

7

Whats with the gears jumping about?



Massive over rev on the mis-selection of forth and some reasonable moments and he still goes quicker?

@neal, you need to understand these cars have big turbos and big power, the throttle is remaining open to help minimize turbo lag. so when they get onto the straight they have the power instantly

Listen to that SR20 scream!

Been round there plenty of times on a bike and all I can say is that was one messy lap!
