Taken from the Official 2012 Dyno Thread in the Dyno forum...

51. Cobalt Daddy, 268whp, 291wtq, Verified Dynojet, GMS1, Graph

I'd say thats about typical for GMS1.

I wouldn't doubt it. Dynojets usually read higher.

A more applicable number would be average trap speed. I trapped ~107mph on my GMS1 only setup (street tires).

I also recall Domistic Rush getting pretty much the same numbers with GMS1 on the same dyno.

To your wheels you can expect 255-270. Every car/dyno acts differently....

ya sadly cobalt is only rated at 280.. 290 is for the HHR and the solstice/sky... they don't have a flattened upper charge pipe to fit under the hood which i think plays into it a bit.

i love how the lnf is such a torque monster!

really if you told someone that your 4cyl put out more torque than horsepower ten years ago they would never believe you, most 4cyls had like 120 ftlbs and 160 hp or something

The old turbo doges from the 80's were the same way as the LNF. They could make great horse power and torque easily and crazy amounts if built. I had 2 and still have one. If you want to see a perfect example and sleeper check out this 12 sec Turbo Woody Van Imagine coming to a light and getting smoked by one?

Yeah, people see at least 350 wtq with bolt ons and a custom tune, some quite a bit higher too. I think Nathan makes like 402 wtq on the stock turbo.
