I finally said goodbye to my cobalt today. Buyer came and picked her up. It was bittersweet. Happy to be out of the cobalt game finally. But i will miss the car and all the memories that i had and all the work i did to her.

Haha amazing. I can't believe someone was able to stand the sound of one of those things for more than 5 mins. I thought people just bought it as a gag gift, lol. Is that a tow strap touching the tailpipe?
Saw this beauty Thursday night downtown... Wonder if those are to cool the brakes?

It sounds like his dyno correction factor is off. From my understanding of dynos they don't care what he car has on it, it takes X amount of power to accelerate mass X. Since dynojets are just a rotating mass, even mustang dynos are rotating masses with build in resistors (for lack of a better term at this hour for me).
His correction factor was way wrong for the 351whp, not the lack of load. 241whp for a stage 2 LSJ is normal, he's just butt hurt a little 4 cylinder can put down that kind of power. To bad you don't have a TVS, or better yet a built turbo'd LSJ like some of the senor members

I think what is misunderstood here is that my car is not a simple stage 2 LSJ. It is custom tuned by ZZp and has everything stage 3 except for the smaller pulley. It has full 3" exhaust, header, large capacity zzp innercooler, stock inner cooler, 2 pass inner cooler end plate, option B reservoir, cold air intake, mass air flow sensor, and again everything for a stage 3 except for the pulley(running gm stage 2 pulley).
The correction factor for this is absolutely correct and the guy who did my dyno (Kevin Murray at MCE racing) is the guy who actually designed they dyno for the company. SO I think he knows what he is doing. That is why he put a 5% load, yes with no load you get a 241hp. But what people do not know is that if you do not put a load on the dyno with a supercharger or a turbo they will not kick in and you will not get full use of them and an accurate dyno read. What the load does is simulate the force and weight of the car that you would get actually driving the car.
I would be willing to bet that if some of you went down and got another dyno run and asked them to put a 5% load, you would find that your numbers are different. We actually ran or car on 2 different dynos , one without a brake, and one with a brake to get the load needed. But if you still think my numbers are wrong, we will see in 2 weeks when I redyno my car with the gm stage 2 computer(stock tune) installed to see the difference in a custom tune, we will show agin load vs no load and then a few weeks after that I will install the 2.8" pulley and the 60 pound injectors and the updated zzp tune.
If anyone wants to try theirs out, Kevin Murray from MCE racing is down at the Savemart 300 in California this weekend and has the mobile dyno with him. And I can guarantee that if he knows how to do accurate dyno for Nascar, that he knows how to do a streetcar. Sorry for all of you that got incorrect numbers by not putting the brakes on the dyno drum(load) to get an accurate read.
What would be really nice is to get a bunch of us together somewhere day to all get tested on his mobile dyno.
Here are a couple of links about the guy and his dyno for those of you that are still question his capabilities and the accuracy of this dyno run.... MCE Racing - Dyno testing, performance tuning, & repair ..... Dynojet Dynamometer

Just an update to my whole dyno tuning stuff. A big part of the reason I plan on getting a second dyno run on my car with the gm stage 2 tuned computer, is to verify these numbers for myself as I am hearing from numerous sources that there should not be such a large difference between load and non loaded hp readings. I think they are referring to a non boosted car. But as I do not run the dynos, and can only go by what I was told, we will find out when he returns to town in two weeks. If I run even close to the same numbers then we will know, but I am going to do a little more research into this

A TVS is a possibilty in my future, but you do not need a built turbo to get these numbers. I have worked on cars and been hot rodding for close to 40 years. I spent half my life as a professional mechanic. I built to show what can be done.

What Have You Done To Your Cobalt Today?
Fixed the sloppy shifter on my lnf. The bolts that were holding the cable brackets onto the transmission were halfway threaded out. Zikes!
