I pay attention to the dyno thread. Get them posted.

I've been super busy at work. That's why I haven't updated in a while.

As long as they get posted in there, they will be one day added to the list.

I will still argue that the + being between stock and the r wheel wise, shouldn't be thrown into the "bigger turbo" dyno numbers. There are a few on the k04 list that dyno'd using the +. I guess with not many posting numbers on the sight anymore it doesn't really matter.

I should re word it... I didn't create the dyno thread... I took over.

In my mind, any deviation from the stock Ko4 should be bunched together. Thats' how I have it in the LSJ section which I thoroughly updated.

Cobalt's drive train doesn't scrub off as much as some. I'm guessing about 12% drive train loss. Now my nova that runs a turbo 409 rwd, it's probably closer to 20%. I know it takes about 20 motor hp more to turn the turbo 400 verses 350. But that's old school stuff you all probably don't care about.

Not sure if you saw my post but my SAE to STD conversion was 1.02225.

You can use that to get a rough idea of yours.
