very old video, but still fun to check out.

 

Wow, nothing like melting rear bumpers! So how does this happen?

 

raw fuel

 

Meaning 110? I thought it was just when you go full catless.

 

full exhaust and unburned fuel basically

 

nice guess guys... anti-lag ftw

 

wow.. that was fun to watch =D

 

i know its anti lag, still the same thing causing the pop

 

those are anti-lag systems. you can tell by how they sound and how the backfire happens a short time after they have let off the gas. They system burns fuel before the turbo to keep it spooled when you are off the gas. Great for racing/rallying but pretty hard on the turbo.

 

You can make a car do that without using antilag. Either you can retard the timing in those high vacuum areas where you let off, or leave it pretty rich there, like 13:1. I have a rich spot up there around 4k rpm and she'll pop once in a while when I let off :biggrin:

 

That video should be re-titled to "How to take 10k off the life of your turbo in 1 minute"

Sounds pretty sweet tho.

 

id hope that everyone would know that was anti-lag.....

 

yes, we have already established that, and the fact that its an old video.
