It seems like i get momentum when i slam it at 5600 rpm, rather than redline, whats best? Ive been driving manuals for about 5 years racing and all, occasionally i can get good momentum at redline, but it depends. Whats the best rpm? (havent JUST practiced shift points/launching with the cobalt)

check the dyno graphs, but i think its right before redline
if you shift at redline, your next gear will be right in the powerband at a good spot

I like shifting at redline seem to work well for the next gear

Another thing to look at is your shift extension into the next gear. What RPM will you be at when you up-shift (usually into the powerband) If you can get an extra 100 rpm from going to redline and sacrifice only a fraction of a second you might come out all the better for it.

yeah i shift right before redline and i drop right into power band cept when i shift 4th to 5th but what can i say its 5th

Taro

Ive never gotten my car to red line in 4th i hit the limiter way before redline.

wikkymaster

same here

Cobalt30

count me in. u gotta love when you can top out our cars in 4th gear at 105 and not even be at redline

TimDang

same here i hate that lol

since the limiter is set due to tire rating, if i put better tires on will the dealership reflash the limiter to a higher mph?

chipsgt

I hope so! But then again, they may not... In my experiance, dealerships are some of the biggest prudes when it comes to performance mods. But then again I am sure there are some that arent either...

Something must be wrong with my car cause i can push 4th gear to like 120-125

FLCobalt

is that not normal? could it be the chip? then again i think i had pushed it that fast befor the chip. ( i know the chip doesnt do anything)

i have pushed all my gears to redline except 5th. but my car has never topped out or hit a rev limiter. and i think my highest was 133?

if you optioned the 16" alloys with pirrelli tires, your speed limiter will be set higher. These tires usually came on the ls and lt models with sport appearance packages that had the middle suspension between the ss and base. better stance and better tires can travel at faster speeds safetly. as for shifting at red line, big mistakes. your engine at certain rpms will only make a certain amount of power. staying in that gear longer becomes usless because you no longer make power and you are actually working against your driveline at high rpms. like opposite from downshifting to slow down.

FLCobalt

shifting at redline always worked best for me

I have michelin energy tires?

forcedgminduction

all the cobalts at my dealer came with pirrelli on the 5 spoke alloys

05sedan

my car as well doesnt have the limiter...i can do 120 in 4th and be just around redline and i still got 5th but wont gain no speed as to where i think the cobalts are drag limited aka more power=more top speed, i have a base model sedan with the sucky 195/60/15 continental tires....i cant get this crappy tires to spin all the way into 3rd lol...all i have is the lower resonator box on the intake removed lol

canada6901

I have a 05 base and it goes up to the incredible nail biting speed of 105 as well. I also have the same tires as you. What all have you done to it? (05Sedan) maybe it's cause you have a sedan?

Clmbngfrk18

yeah i can hit 120 in fourth i managed like 123 once but it took a while to get there and is was probally with the wind lol

tmade

I hit 115 in my base model mtx, but pulled it back down after that...I was catching up to traffic.

AmericanRevolution

Best shift points I've found are between 22-2500 RPMS not only does it make you SUPER fast but it good on the wallet.


=P whats up ryan

jtvictoryred05

why do u guys have govenors. i can top out my speedo

forcedgminduction

if you have an ss, they will. the 05's came with perrelli's while 06's come with michelin. and the speed limiter is set different for each vehicles different configurations.
