on a test-tune night going after green doesnt mean anything. the timer doesnt trip until the car goes by it, so no time is recorded until the car moves.

FUCK MAN I know. But hey, do u want to watch TV on ur PCYou'll get all the SKY CHANNELS there isAND from any country IN THE WORLD, on your pc screen!!!!Go to this website...frexis.*com/PCTV21.html(DELETE the *)check it out................its cool, i've got it myself.

It is a matter of traction. The amount of power the wheels can convert to forward motion increases sharply with the speed of the car.For best acceleration, you ideally want a "peaky" engine with a relatively linear increase in power as the revs increase.But you're right about the other thing, the sudden surge in power deliver that you see with small-displacement engines is also undesireable.

How is a flat torque curve evil?? Thats what ppl aim for. And the problem with big turbos is completely the opposite with a very steep torque curve. Small powerful engines can quite often double there HP in a few thousand RPM as the turbo comes on boost.

Wow, I think its hilarious that people are so critical of a car/guy that are running in the low 8's.

hes losing the time on his 60 ft. theres room for improvement

You're talking about turbo-lag. That's a different matter. You're absolutely right, you can reduce turbo-lag by increasing the displacement of the engine. You can't eliminate it of course, but the real evil of turbos is that they flatten the torque curve - delivering more power at low revs. On paper this may not seem so bad, and in lower-powered cars, it isn't. But when you're already at the limits of adhesion (e.g. a Viper), turbos push you well past that limit with unfortunate results.

Well, if you need to get two turbos spinning, you want to do it with as much air as possible. More volume flowing through an unchanging cross-section of pipe (aka an exhaust) will have to flow faster and increases the pressure applied to the turbines. That's why no one runs twin-turbos on a 2 litre honda, it takes to long to spool. An 8 litre viper takes very little time to spool up two small turbos, so the power curve is usable.

Yeah I see he sat there a bit on green. In drag racing this is bad. What was he waiting for? He could of had better times if he would get going. He not very good at drag racing. Showing off maybe but not a drag racer.

i love the way it just jumps off the starting line
