Spanked a TC Cobalt SS
I have yet to run anyone in my TA with my new vortec heads, usually I don't don't run many people but this guy was riding my butt for a while and it was obvious what he was gonna do so I thought why not lets see how my old 84 does,
We were single lane and he was about 4 inches away from my bumper. I was driving normal, he was riding my butt. I took off normally and slowly brought it to 40mph as I would any day. When the lane split into two he took off to pass me just as expected.
I am fairly sure he was in second and so I dropped it into 3rd going 40mph and very quickly put a couple lengths on him. I shifted early into 4th at about 75 and put one more on him before I shut down and he did the fly by.
Those turbo Cobalts are quick 260-280HP I was surprised how well he did. That turbo was really loud I could hear him the entire time. I don't know all his mods I noticed some appearance mods and he had some kind of exhaust system.
It was a good day for the old 84 TA

Re: Spanked a TC Cobalt SS
SS/SC Cobalt should mid to low 14s around 95-100mph with a average driver. The turbo should be significantly quicker trapping 103-105mph.
I've seen them go mid 13s bone stock.

this guy had a handful of 14.9-15.0 slips which is why I ran him. if I thought it was a 13sec car my brother would have raced him.
I also thought my fbomb was a lil quicker then 15.4

when my brother first got his car he ran a 14.0@97 it was late in autumn and cool day
the only time I ran my car was a 90* + july day, my brother ran a 14.4 and I ran 15.4 so is it safe to assume I could take a 1/2 sec off my time on a cooler day.

Re: Spanked a TC Cobalt SS
ET means nothing to temp. Too many variables.
trap speeds are what you want to compare.

Re: Spanked a TC Cobalt SS
And watch out for Focus ST's too. They are having issues getting out of the hole, but from are trapping between 95 and 101mph depending on the driver. People are revving the **** out of them up to 7000rpm. WAY out of the engines powerband. The power band is actually from 3000-5000rpm when the Overboost feature is kicking in provide an under-rated 270lb/ft from 2500-4500rpm. Cars weigh about 3250lbs for the heaviest model and are putting down about 230whp stock. Tunes bring them to the 250whp range with over 330lb/ft at the WHEELS.

Personally I have never seen a stock one run better than 14.0 at the track.
Either way I was happy to walk him. I was glad we went from a roll I am not a fan of launching the car hard.

Re: Spanked a TC Cobalt SS
I need to do something about the rims they are beat. I am thinking about stripping them, polishing the aluminum then masking the front and painting the insides black.
