I made it to the dragstrip finally to attempt to show the difference with the Jet Performance Modules. 1/8th mile track temperature was hot...81+ degrees, 8-17 knot headwind, high humidity. I wanted to make at least 6 runs -- 2 with the stage 2 module, 2 with the stage 1 module and 2 without the module. Unfortunately a Nova blew it's transmission at half track and closed the dragstrip for over an hour. Time trials closed for racing so I wasn't able to get but 2 trial runs in -- first with the stage 2 module since I already drove it there with it in. Then when I realized I could only get one more run I went ahead and put in the stage 1 module. Kind of a wierd feeling to change out a module and pick up 3 tenths in the 1/8 mile.

Run with Jet performance Stage 2 module was a 10.076 @ 72.07
Run with Jet Performance Stage 1 module installed was 10.308 @ 71.11

Notice the difference in time at the bottom of the time slips -- due to tranny fluid having to be cleaned up.

I'm pretty confident I could have gotten in the 9s with cooler temperatures and by taking out the spare and TTR sway bar...and losing some weight myself

My reaction time sucked too -- first time I've had the Cobalt on a track. 60-foot time was 2.41 -- I don't think that's too bad with an automatic. Going to have to learn to "hammer" it before the last yellow light.

I have pics...digital camera died but picked up an instant camera -- have to wait for developement.

With Auto tranny my Cobalt shifted into 3rd just as I crossed the 1/8th finish line! 70 MPH top of 2nd

 

sweet finally some kind of results would have been better with some more runs and maybe a 1/4 track but non the less good **** man ur the first to finally post something about these jet modules, hopefully there will more more evidence from more people in the near future.

 

The tone of the exhaust sounds different with the stage 2 module too...deeper and "raspier". Can really tell the difference after coming off the line -- with the stage 2 module the car felt quicker after the initial jump. Both modules felt the same to me in 2nd...the car shifted into 3rd as I crossed the finish line with both modules.

 

not bad, you should of ran without another mod. in also
