It's called "powerbraking". It's done at a drag race (for example) to get the turbo to spool up so you launch at full boost vs bogging off the line.

Unless the HHR SS is different than the Cobalt SS (and I don't think it is) you do not have to be in comp mode to do NLS. It will NLS in any of the three trac control modes.

 

ya but you can power brake in any vehicle and you dont' comp mode. My friend use to do this in his s-10 all the time.

 

Yes and I did it all the time in my Neon whenever I raced it at Englishtown in Jersey. Brought home many a trophy too.

 

OK, I know this sounds really dumb but I FINALLY used the competition mode and after 5 years, wonder what the heck I was waiting for. First couple tries got bogged in 2nd. Then basically waited until 6500 to shift to 2nd and whammo, success. I live in a stupidly suburban environment so I don't drive like this very often. Sherrif sub station and Trooper barracks to boot means I have little chance of getting away with screeching any tires. Plus I've taught here for 14 years so someone's going to notice. My kids are also old enough to mess about a little and they actually like it when I hit corners hard so goodbye expensive tires, it's going to be a fun summer.

Cool it was almost 4 years ago Asanti was talking about it. I don't race about either, ha ha ah, anyway I find a little satisfaction with traction off and use L and I on the shifter. But I have to admit my transmission was retuned with the Trifecta. That combination works best for me....
