I tried to do a 60-100 starting at 60 in 3rd with no boost and rolling into the throttle...
YouTube - 60to100attempt.3gp

Then I figured I would be alright if I started at 70 in 4th...
YouTube - 70 to 120 spinning.3gp
When I let off, the actual speed was 120, which means it went 70-120 in less than 4 seconds spinning badly.


Yeah, I know my message center is blown up. The airbag sensor under the passenger seat is unhooked and the coolant level sensor is broke. Oh yeah, and I need to change my oil. And get some fuel... Anything else?

 

lol wow

 

LOL Holy crap! Those lightweight wheels in the turbo can really spin up quick!

 

Jesus that insane lol

I figured you had a better clutch in it, but thats still a lot of power for a clutch to hold! Props to you guys for making awesome parts

 

yeah the EFR's are no joke. I heard about the EFR's in october last year and ive been so excited ever since. And the fact ZZP is making a bolt on one so i dont have to buy a bunch of new parts makes me soooooo happy!! i cant wait!

 

This is at what power level? 540?

 

Same as the last dyno pull, so just under 500. But that would be the corrected power. The street doesn't correct the power. should be about 525 uncorrected at this boost. It has dyno'd about 50 higher.

 

Id really like to see a pull of it making 420whp since thats my goal

 

Your tires hate you

 

can you list the mods done to that car in the video?

 

My air bag light is on too....

 

when is this turbo going onsale?

 

reading>everyone that keeps asking for a price or release date
chillax ppl the info will come when ZZP knows for sure

 

!!! 60-100 in 1.5 sec???? Mercy.

 

Id say it was more like 4 sec. Its so hard to tell with the tires spinning. Need a gps or something to really be able to tell

 

Pure sex i cant wait till it hit the shelves and my engine bay

 

NO..I'm not talking to 120...take a look how fast it takes from 60-100 in the first vid..less than 2 sec!
fastest cars here with 390WHP do it it low 4s.

 

OMG people the speedo might have been reading 120 but the car was probably only going 60. There is no possible way you could extract an accurate 60-100 time from that video.
I know I'm saying this on a Cobalt forum but FWD FTL. 500whp but only 170hp to the ground.

 

Watch the tach bouncing off the limiter. When he starts to let off the gas the wheels grab and the tach snaps back to around 6k at around 100mph. Looks to be in the 3-3.5sec area while raping the tires the whole time. Its hard to tell especially with our laggy ass gauges.

Throw some slicks on it and lets see what it can really do haha

 

Those vids are ridiculous!! So much power!!

There are no downsides to a larger turbo when it spools the same as stock, thats amazing.

Matt -

Any estimate on what kind of power this turbo would produce on 15PSI (stock boost pressure) with just an intake??

In other words I'm just trying to see if you could estimate the net gain going from the stock K04 to this turbo while leaving everything else basically stock.

 

haha ronn

 

My god :O I think my turbo just blew it's seals and is in desperate need of replacing!

 

Oh. ah-My. ah-God.

Edit: i wanna see this vs. ryans lsj........hmmmm.

 

ryans lsj would annihilate that car.

 

OK..some wheel spin, but under 2.5 sec is definitely possible.
Look at this RUF Porsche...and this is 469 Flywheel HP listed (less HP than Matts)..same curb Wt as Cobalt:
