ZZP EFR Cobalt 60-125

Running 60-125 in 4th gear with the ZZP/EFR 6758 turbo. I started at 60mph in 4th with no boost. When the boost hits, the tires spin to 125, hang there for a bit, then grab full traction at 120. I let off when the car actually hits 125. All this in about 5 seconds!

Sorry Jsanchez- I didn't mean to remove your last post. I was re-arranging mine and now yours is gone. Anyway, these are in response to you saying that if the awd has less tirespin, then it must be faster...

What size tires do you have?

[Stattama]

@BLACKSSG85 245/40 18 on factory wheels

beautiful

@jsanchez430 NP! No reason to start anything ...... Your point's are valid .... I think most would agree that FWD wasn't designed for motor sports (shhhsh dont tell my cobalt lol) ...... more for MPG and reduced build costs.

That said.... ZZP has really brought the cobalt SS to a very respectable level that can compete (and beat) cars that were designed from the start to be sport cars. I'm sure you'll agree 60 to 125 in 5 seconds in a FWD car would be a fun ride 8)

@jsanchez430 Therefore, even though some power is wasted due to traction limitations, there can still be more power utilized overall. To better understand this, imagine how a torque converter works. When people run engines that make a lot of power at higher rpms, they run a higher stall converter to allow them to spend more time in their power band. Spinning the tires has the same effect as long as tirespin is not great enough to allow the engine speed to go beyond the power band.

@jsanchez430 You are missing 2 important components in this equation. 1. If the AWD car is making the same power at the flywheel, it will be making less power at the wheels due to a much greater percentage of drivetrain loss. 2. As I stated earlier, tirespin can actually be an advantage, and likely is in this case. If you look at the dyno charts for this car, it makes a lot more power at 6500 rpm than it does at 4000 rpm.

@jsanchez430 No, your point was its a fail, and in fact it is not a fail. Sure awd could do better, but in these circumstances this car did damn well.

@rukkee22 Great way to put it! Thanks for not trying to start a war on here. I like cobalts! My close friend has a 400+hp cobalt and it's pretty quick!

[rukkee22]

@jsanchez430 No argument here..... FWD has it's limits and there are better platforms for putting power to the ground . I have a Turbo Cobalt and it's a blast spinning in 2nd from a 40 mph roll ....it's inefficient and tears up tires .....but it's a lot of fun.

[jsanchez430]

@rukkee22 how about getting you the point you're trying to get to without wasting time/power/rubber to get there? you're correct, it may be fun, but efficiency is better :)

[jsanchez430]

@DwnNvr maybe you don't realize what my point is. awd would "move the fuck out" in the same way with the same power, but it won't spin tires getting there, hence getting to said point faster. understand? or is this making you think too much?
