Wooped a Cobalt SS turbo

Testing a 19c friday night i was paired with this guy twice. It still had the temp tag in the back window so it may have still been on the break-in fuel map.

His 60's were crap, but with a 100 mph trap speed beware of these on a roll.

 

I left him like a stone on the second run. :hmm3grin2orange:

Mt two best runs of the night.

Not sure i like this turbo though, those times did not come easy. I had 5 crap runs. After i upped my 1/2 and 2/3 shift to 5500 it worked better.

never mind...

 

The new SS differs from the previous supercharged SS in a number of significant ways: For 2008, the Cobalt gets a turbocharged version of the 2.0-liter Ecotec four, complete with direct fuel injection and a relatively high 9.2:1 compression ratio.

 

This combination provides a high specific output (260 hp at 5300 rpm and 260 lb.-ft of torque from 2000 rpm) with rather economical performance—Chevy is claiming 22 mpg in the city and 30 on the highway. Controlled by an electronic wastegate, the Borg-Warner twin-scroll turbo supplies boost at very low revs, yet can pump as much as 21 psi when required for maximum power
