Prep for Drag and Dyno

I think mythbusters did a segment that tailgate down actually creates more resistance than tailgate up! - whether it makes any significant difference to the 1/4 times, I don't know.

Yeah I saw that aswell, they said if your going to leave it on then the best thing to do is leave it up

Also put some octane booster in your fuel. Remove the air filter if it isn't the factory air box. And at the drags drop the rear tyre pressure to 25psi.

Does the octane booster work if you run 98 octane fuel or is it more for 91 95 octane fuels? cheers

So its better to have it off than to have it up?
