Just wondering if anyone could tell me what speed the car can do in 1st, 2nd, 3rd, 4th, and 5th gear. Thanks

 

1st is about 28mph

2nd is about 62mph

3rd is about 93mph

4th is about 124mph

5th is well....redline so 157mph??!?!?

 

Depends on your rev limit too. I get 70 in second, 110 in 3rd etc.. top speed is higher then 157 also

 

Same. I have hit 73ish in 2nd and about 114 in 3rd. I've buried the 160 speedo, so I don't know the top speed of mine.

 

This is for a stock tune i'm guessing

 

Second goes a little higher than 62 on the stock tune. If I NLS into third I'm hitting 70mph easily. I realize the car will coast to a higher speed even during the shift, but I'd wager I leave second at probably 65+mph.

 

oh, I guessing, lol. based on what I know I do at the track. I have to hit 4th gear to get to 100mph or more.

yea stock tuning

 

Alright that sounds good, I just thinking about where I'll need to shift at on the road course

 

You have to watch to if your tuned because the speedo lags alot.

 

^tru

 

This is for stock tires and stock redline:

1st gear - 36
2nd gear - 69
3rd gear - 103
4th gear - 136
5th gear - 173


Like it was mentioned, you have to watch out because the speedometer lags alot in low gears.

 

You should be looking at the tach, not the speedo, to see when it's time to shift.

EDIT: Sorry guys, I fixed the spreadsheet for the correct tire size:

EDIT 2: See 2nd post.

 

That appears to be LSJ specs, that's why...

 

I guess I kind of worded that wrong. I was just wondering the actual speeds. I know that the tach is the important part.

 

That spreadsheet is wrong.

The F35 MU3 in the 2008 and up cobalt SS with LNF has a 3.82 final drive not 4.05 which is the LSJ final drive. Also, the LNF stock redline is 6250 RPM.

 

I made the spreadsheet as a tool to see the relationship between rpm and mph for different combinations of tire size, final ratio, and trans ratios. I only got my cobalt a few days ago so I have yet to learn all the differences between models. If anyone wants to play with a copy of the spreadsheet, I can email it (since I can't post .xls files).

 

Like I said, those are the LSJ specs...

 

2008-2009 Cobalt SS Transmission Specs are:

GEAR/RATIO/OVERALL/(RPM)MPH

1st,:1 - 3.38/12.91/(6300)36 mph
2nd,:1 - 1.76/6.72/(6300)69 mph
3rd,:1 - 1.18/4.51/(6300)103 mph
4th,:1 - 0.89/3.40/(6300)137 mph
5th,:1 - 0.70/2.67/ est(5800)160 mph
Final Drive Ratio 3.82:1

 

Im on stock tune and i always trap 103mph at the track, hitting the rev limiter right before the line.
Half time it say 104mph, but its probably 103...

 

GPS certified on MY car:
1st --> F($*/&?ing too short, Jesus GM that's a 260 lbs-ft car. (FYI- a mini cooper s gets to 43mph in 1st)
2nd--> 69
3rd--> 104

 

this is with the stock lsj trans left and the lnf trans+ raised rpm right

what mine will be with 7350 rev limit: but i will prolly shift at 7500-7600
1st Gear : 42.91MPH
2nd Gear : 82.42MPH
3rd Gear : 122.92MPH
4th Gear : 162.98MPH
5th Gear : 207.22MPH

 

just listen and feel how ur car can handle each gear... its okay 2 tap dat rev limiter
