13-up SHO upgrades / dragstrip ET/trap speed

[metroplex]

I was at the track today testing/tuning my Cobalt SS Turbo when I saw a gentleman with a 2015 SHO. He ran a 12.7 @ 106 when I was paying attention. He had an open exhaust downstream of the cats, a Diablo tune, a drop-in K&N filter, smaller diameter wheels with drag radials, and a manual boost controller. I saw a vacuum hose/check valve attached to something on his intake manifold. He was also running the stock 2-bar MAP. He didn't mention methanol injection and I didn't see a tank. He tried to do a burnout in the box and the car just chirped. It made me wish my Cobalt was RWD or AWD.

I haven't had the time to bring my 14 SHO to the track to get some baseline runs. What's achievable with just a tune? I thought the stock SHO's were running high 13s and trapping around 102 mph?

FWIW my Cobalt was running 14.2s all day long with 8 year old factory tires (ContiSportContact 2 summer tires) but with speeds averaging 106-108 mph. The more power I grab out of that engine (the cast pistons are the first limiting factor), the less traction I get for launching. It makes me wonder what I could do with the EcoBoost Mustang even if it is only a 4-banger.

Did you ever get any datalogs posted?..would love to check out how hard she is running

You're too paranoid lol...people post logs here all the time..just confirms a clean tune/pull...for people that dont know what a good log looks like , its a chance to educate the community also

[AJP turbo]

Nope. This is a good forum...the only fighting is me and Z lol...i dont think anyone here including the moderators would care if you post a log...in fact they may encourage it.....most people already know who the tuner is and really dont care....one mod already approved of you posting a log

I ran 100% bone stock 13.79@100.5 mph (non PP).

And yes, your Balt SS seems to be very traction limited. Stock they ran 14.2@102 mph.

I'll say a few things. First is I had a fast car with his tunes. Second I never had problems with the tunes. Third is I would NEVER deal with him again if he gave me $5000 to run his tunes. And I had the fastest SHO without meth for a long time before Rich beat me by less than a tenth. So that should tell you something

I have the supercharged cobalt and they are worse than the turbo ones regarding traction. IMO, I think the only way these cars can have optimal traction is with slicks.

That applies to any FWD with significant amount of tq.
