now for the one i think every one wants to know.... hows the tranny holding up??
one other thing, you said for the 240 whp and 241tq you didn't have a cat and was running a big exhaust (guessing the 3 in. pipe). what do you think we would get if we keep the cat and maybe use a little smaller pipe (say 2.5)?

Thanks to everyone for the glowing words and interest in our Cobalt offerings. I wanted to stop in quickly and let you know that I will return this evening to address your questions.
We should have pics of the 2.4 turbosystem available to view tomorrow!

1. We must do a prototype car that establishes viability.
2. There must be sufficient demand to justify entering production with an automatic version.
We'll begin to seek an automatic car later this year.

One aspect of the Getrag transmissions used in Cobalt that is very unique (and very encouraging!) is that unlike most other transaxles in this segment, they use three gear shafts as opposed to only two. This spreads the loading among 50% more bearing and shaft area, as well as allows the individual gearsets to be as much as 50% more robust in size.
Another great attribute is the size of the differential ring gear...it's like 8.5" big!
Overall, it's a quality transaxle from a quality supplier, and appears to be well up to the task of higher power.

Since it hasn't been touched on by Bill, I'll note on one thing...the group buy you all want.
From my past experience with HRC, yes I sell for them and love doing it, they do not do group buys. They simply have too many companies selling their stuff to give one or two a steep price break without upsetting everyone else. I know in the past, like with the Cav kits, they offer a lower price when the kit is first released, and then raise it after a preset number, usually 100, kits have been sold. If this is different then I'm sure Bill will post up.

Upon disassembly, all that transmission showed was some excessive wear to a differential side gear thrust washer. Chances are good that washer suffered during burnouts with the slicks...it's hard to keep both slicks rotating at exactly the same speed with an open differential.

Well I guess that solves the tranny banter.
