I finally found it and got it hosted!


This was about 3 weeks ago, only mod is an Injen CAI. On the Same dyno, my friends srt-4 made 271 whp, 304 wtq. Also that day was a 256 whp 350Z, an 02 mustang V8 automatic spraying that made 310 whp with spray, 225 whp without it, and a 2004 G35 automatic sedan that made 227 whp.

BTW, 1st pull was 3rd gear, 2nd was 4th, and the 3rd was in 3rd after we sprayed my H/E with ice water.

 

SWEET #'s man!

 

Congrats, that almost looks like stage II numbers.

 

Everyone that was there that day was surprised. The really odd thing, this was most of these guy's regular dyno, and they were making numbers right where they thought they should be with what was done to the cars. Mine was the only completely unknown car there, and the first Cobalt to run on that dyno.

 

you sure you don't have stage 2? That seems like a pretty inflated dynomometer. I dyno'd at 238 whp with stage 2 and intake. Tell those guys to get their dyno fixed, it's a POS.

 

Then why would every other car be putting down numbers in the right range for what they had? Did you even read what the others put down? And I can go in the garage and take a pic of my pulley. Most of the people I know around here are thinking more factory freak than goofed dyno.

 

So from what you said, That you sprayed ice water on your H/E, and you made MORE power, then a Nitrous spray bar would work great, am I right?

 

It picked up 5 whp after doing that. I don't know about trying to setup a spray system. Seems like the intake is in a bad spot for that. We mainly did it because we could spray it while the car wasn't pulling flowing air in. I know a setup like this works on the mini s because someone I know has that setup (IC sprayer, smaller pulley, intake, exhaust, 197 whp, 167 wtq). But the IC heat exchanger is in a different location (on top of the engine), so they kind of need something like that.

 

Yeah but I have a front mount heat exchanger

 

There are definitely people who know more on this subject than I do. We were mainly seeing if the cold spray would even make a difference. The Srt-4 tried it too, but he lost 3 whp, and picked up around 5 wtq when he did it.

 

I own the same dyno , those pulls were done with the std correction factor (gives you higher numbers) and the smoothing is turned down to zero (you can see this in the top right hand corner of the sheet), those are not SAE corrected numbers and when you set the smoothing at zero it makes the lines jumpy inflating your peak numbers , go back there and ask him for a graph with the smoothing set at 5 and the numbers SAE corrected . When you see something like this you are providing false information for the guys on this board (not sure if you even knew the dyno operator was doing this). My guess is that you will have around 15 whp and 15 wtq less once he corrects this , you don't have to redyno , just ask him to change the settings with your file pulled up and it will give you the right numbers .

 

Kind of hard to get him to change that, since they were just printing them after your run and then deleting the file. First time I've had a car dynoed. One thing I don't get though. If EVERY other car that was there, that had run on that same dyno, was consistent with what they had done to the car, why is mine screwed up? Seriously, I am wondering this.

 

I checked out with my winpep7 and compaired to my early runs of 237.42 209.78 tq SAE Smoothing 0 on STD Smoothing 0 it was 244.26 215.83 so you should be around 230-235whp. 200-203 still very Good

 

You can not base it off of that because you don't know what the sae correction was where his car was dynoed as it could be different . Why would they delete your file , that is odd , it automatically saves the file .

 

It was deleted because it was a cheap dyno day, not tuning. 3 pulls for $40.

 

Nice Numbers...similar to mine...
