very safe. it's how you do 1/4 mile and other benchmarks on a dyno.
Yeah, but why would you want to do that? On a dyno, the acceleration times would ignore vehicle mass and aerodynamics.

It's for dyno tuning. Obviously if you've stepped up a half second after a tune you've made an improvement, be it your actual ET or not. It's just relative.

That's retarded... there's still no need to do a clutch dump like that. Every reputable tuner I know simply engages the gear gently and goes from there. You're tuning the engine... not your shifting abilities, etc. If you want to tune your engine, do it on a dyno. If you want to do a 1/4 mile run, do it at the track.

TUNE IT THE WAY YOU WILL DRIVE IT.

PITA driving to the track, back to dyno, to the track, back to dyno. The only thing you tune based on track tuning afaic (c=care) is suspesnion, tires etc...

They do the same thing here while dynotuning. If you're not gonna launch it, you're not gonna have a fcking clue what to do to make your run better.

^^ agreed.... with the torque that thing has and the fact that the rolling resistance is less than it would be on the street, he could have just as easily put it in first and romped it when ready. (although with the turbos, maybe he was trying to stay spooled?)

God I hope you are kidding, because if you aren't, you are just as stupid as the person on the dyno.

Dyno's are a instrument to tune an engine to be reliable and pull more power, they aren't there for any other purposes. Those straps that are holding that car down are not that strong, and if one snaps there could and probably will be a lot of injuries.

A full gear acceleration run can be handy, but actually drag launching on a dyno is totally pointless . . .

The car isn't seeing anything close to actual track traction & inertia conditions, which means a "perfect" launch technique on your dyno will be different than in real life. It also means clutch and tire slippage become variables in the run, making any tq/hp comparisons useless.
