So, I understand there are a LOT of variables as to what makes 0-60 or quarter time for a car...but given estimates and those currently modded, considering the SS/TC seems to range from 5.5 to 5.8 for 0-60 and about 13.9 or so for the 1/4, any estimates as to what we could be seeing with the stage kit, if it is 315hp as I have seen?

Anyone here have about that much power at the flywheel? Any 1/4 mile times to share?

I only ask because I'm antsy as hell and I cannot wait to get my stage upgrade...the money's just sitting in the bank til it comes out.

 

I'm only hoping for a tenth and 2-3mph from the stage kit. To be honest the car may actually be slower in the 1/4 assuming everything else is stock.

Fwd FTL

 

I don't see much gain except in terms of 1/4 trap speed or on a road course. In terms of 0-60 sprints, the car won't be any faster... In fact, without a good driver, it will likely be slower.

STOCK these cars run 5.5 sec to 60 due to traction limitations, not power limitations. Any added power only reduces the chances we'll have available traction at launch.

 

Hmmm...well maybe I'll wait for someone to get it and post up some numbers

Problem is, I do most of my runs under 100mph, usually from a light or a rolling start like 20mph, and as I experienced this morning, given poor road conditions and the right kind of shift you can spin the tires up to 100km/h.

From the looks of it, the stage kit may just end up costing me more in tires and not actually make the car faster.

 

Provided you're smart about using your right foot, you will still make gains on the street... I spoke of traction issues from a drag racing perspective. On dry roads, you should be able to hook the car up from a roll with the stage kit.

For a guy like me who doesn't go to the drag strip, I'm thinking of getting the upgrade since it will give more midrange punch with those huge torque numbers. Who doesn't like that kick in the ass you get when you drop a gear or two and get on it?

 

If you can get decent traction, typically every 10 HP more to the wheels will give you approximately .1 lower ET in the 1/4 mile. The GM stage kit with an intake should be close to 1/2 second quicker in the quarter, if you are a good driver.

Not sure where you came up with 315 HP, GM has not announced numbers for the Cobalt stage kit yet. On the Solstice, Sky, and HHR it's rated at 290 HP.

 

I don't have a link handy, but I've seen the 315 number floating around a few sources...but keep in mind I said IF.

I guess it's true tires hook up better on the street than on the track, and I find given a roll, a downshift to 2nd from about 40mph does give decent traction, which could prove to be useful with the kit...

 

My main worry in trying to get the best time is I've seen a couple peoples car going into limp/safe mode if thier tires drop below 30PSI.* I've seem mine come on once* right at 30 and filled it up right away.* I'm planning on trying 30, 28 and even as low as 25-26 at the strip at the end of the month....not sure what to do. I've heard it's possible to disable it??? HOW?

 

From a dig my car is slower to 60 mph than stock ,I think, but when am passing this thing is fast. I blow by people faster in my TC now than my LS2 GTO used to. With a set of drag radials and a lot more high powered fwd driving experiance I believe that I can run high 12s or ver low 13s in the quarter.

 

Yeah with a good driver mod the car will hit 12's easier than any LSJ ever did, but these FWD cars are such a bitch to launch.

 

hmm i wonder what the difference between LSD and non LSD would be in the 1/4 mile, assuming everything else is the same.

 

i posted somthing like a month again stating (from gm) the cobalt would be 315 and it also said the manual hhr ss was 290...... i don't know if either were to the wheels..... i'd have to see an hhr ss stage 1 dyno

 

Stock there is very little difference but tuned I am not sure depends on how good the driver is at controlling wheelspin off the line. My car has all the torq management removed in 1st gear and 2nd so wheelspin is a fact of life for me now. I need better tires dammit.

 

That would be great if it was true. Knowing GM, that's probably at the flywheel.

 

if they push 30 more at the flywheel, and stock tcs make 240-250, you can expect 260-280 whp, and who knows on torque

 

Well, everything else remaining equal, I trimmed 1.2 seconds off my best ET in the Neon, adding roughly 140whp over stock. Picked up 14mph trap speed. That's with REALLY crappy street tires though.

I'd make the assumption there would be a decrease in 1/4mi times in the Cobalt.....if the driver ability is there.
