I just watched YouTube and watched the Stock 2.2 Cobalt 0-60 in 8 seconds video and then watched a video of a 2.4 with a GMPP exhaust and GMPP intake and it was upsetting.
The 2.4 had a 0-60 of 8.7 seconds, .7 seconds slower.

I know that the 2.4 has to have something wrong with it or the passenger in the 2.4 weighs 500 lbs.

Is this common? I mean come on, a two bolt on 2.4 being .7 seconds slower than the 2.2?

I now worry about getting GMPP bolt ons.

I thought about how one driver could be better than the other, but the video shows that both were floored and getting up there in the RPMS, no faultering to be seen. I could be wrong, I am not an expert on this.

 

im pretty sure those parts arent gonna decrease your preformance. I dont know whats up with the videos

 

has to be the drivers. in my stock 2.4 i can do 0-60 in 7 seconds.

 

Watch the lag on the 2.4 from 54-60mph, its like it hangs there too long.

 

he needs a driver mod

 

lol!

 

ditto. stock time is like 7.1 right

 

dont beleive everything you see on youtube?

2.4 is faster then a 2.2. stock for stock obviously.

 

"dont belive everything u see on tv"

 

i know i can whoop a 2.4

stock for modded that is :P

 

Couple of possibilities:
The 2.4 owner is using 87 octane fuel -- which will most likely cause the knock sensor to reduce power.
GMPP Touring exhaust is only 2 1/8 inch ID, stock is supposedly mostly 2.5" -- I got rid of my Touring because I felt it slowed my 2.4.
If it is auto could be starting off in "D" and the traction control is kicking in -- also reduces power until 4K rpm

Simple fact is 20 -- 30 HP is not big enough to make a HUGE difference in performance...but if any of the three possibilities above happens it makes the 2.4 ssslllooowwweeerrr...

 

He must be running the 87 like you said, needs and oil change bad, a new fuel filter, needs to know how to drive plus he and his passenger must weigh 300 pounds each.

 

maybe if he added a tow hook in the front and a fire extinguisher on the a pillar and cut the holes in the back bumper he would go faster....

 

i can usually do 0-60 in bout 5.5 seconds

 

ZZZZZZZZZZZ...wha...Oh, not important...ZZZZZZZZZZZZZ

 

Your 2.2 can do 0-60 in less time than a 2001 Trans Am?
What mods do you have? Turbo intercooled plus all the bolt ons?

 

mad parts yo
