they are breaking in the clutch

 

They are seating the clutch. You break a motor in!

 

Ya but are they just blipping the throttle, or is there somethig they have rigged for this?

 

They are blipping the throttle. The guys at the back of the car are holding it down so it does not jump off the stands.

 

Wow. it sounds like loud POP, more thn just a blip of the throttle. Thats crazy though.

 

same difference

 

yes they are seating the clutch. You should see it in person. It is an awesome sight

a pop is an understatement. its more like a small bomb. lol you can be a few hundred yards away and it will still startle you, now you can see why the person taping it 5 feet away almost fell over.

my wife went with me this year for the first time we where watching the warm up and i saw the guys grab the back of the car. i told here to get close and watch as i took 5 steps back very funny to watch

 

Hahaha, I love nitro!

 

So what im looking for is more of a technical explination. I can understand they are seating the clutch, but its not just a fact of them blipping the throttle. its like there a ton of timing advance...almost like an antilag situation, but i know thats not whats goin on. So what is goin on when they do this?

Thats not seating the clutch. The tires never move. That seems more like something went wrong. Not to wrong because nobody seems to worried about it. Thats to short of a blip to seat the clutch. maybe they are testing the fuel valve. Or throttle response.

As for seating a clutch.

Just like when you put a new clutch in your car you have to break it in. you have to do the same thing to a slipper clutch. You want all the surfaces to mate as close a possible.
The way you do that on a fuel car or any other car when you can drive it for 500 miles is to put it under load. You will grab as much break as you can and let the clutch pull down the motor or pull through the brakes. When on stands the weight of the car will not help so the grab brake and than rev the motor.

I think you need to watch the video again because the tires do move.

I was just gonna say that/

 

You are right. They do move! Dont know what i was looking at last night. Thats still not enough to seat the clutch. it is a very fast throttle burp.

 

Crazy

Yes it is.. And that's what they do.

 

Isn't that just like .080 of the throttle?

 

with that much power, it doesnt take much effort to seat a clutch.

 

Sure looks like them seating the clutch to me.

 

there are different methods to seating the clutch. that is one of them.

 

the other is doing a burnout...

 

yep seating the clutch. thats how most of the teams do it. sometimes they blip it more than once. that **** is bad ***
