We now have the second round of C7 dyno test results. First testing was done by edmunds.com about three weeks ago, resulting in rear wheel amounts of 407 HP, 411 TQ. The complete article is at: 2014 Chevrolet Corvette Stingray Z51 Dyno Test on Edmunds.com

Motor Trend's dyno run, done a few days ago, measured rear wheel results of 400 HP, 402 TQ. Results at:
2014 Chevrolet Corvette Stingray Z51 Dyno Test - Motor Trend. In that article they note: "Factor in drivetrain losses and you’ve got almost exactly what Chevy promised at the crank. That SAE power certification really does mean something." If you want even more about MT's dyno testing: 2014 Chevrolet Corvette Stingray Z51 Dyno Test - Motor Trend

As we all know, dyno tests vary between the dyno testing equipment, temperature, humidity and many other factors. Both articles verify GM's initial press release claims that the LT1 has a very strong torque curve, echoing the Z06's 427 torque, to 4,000 RPM.

Here's another Dyno test with a K & N prototype filter. Awesome numbers to say the least.

My apologies if this has already been posted.

Thanks for finding and posting. Amazing that just with their protype air filter, the first time they saw a C7, they got 15+ HP with that prototype.

I'll be pre-ordering one of those filters, for sure!

We know have a video of a third round of dyno testing, this time testing by Lingenfelter Engineering. Results were 416 HP and 416 TQ, higher than the last two tests and proving, once again, that dyno test results vary by each dynamometer, humidity and temperature the day of the test, and, why comparing results on different dynos, different days, especially at different altitudes has never been a good idea.

However, using the same machine to later see what Lingenfelter's C7 upcoming power package results show, and adjusting the final results by corrective factors for temp and humidity, will give us a pretty good comparison for how effective the Lingenfelter C7 package is.

do a google search on K&N - they use an oiled filter and other, better intakes use a dry type filter - never have seen K&N hold up in 3rd party tests....Wait for the pros at this like CAI, Inc and Roto-Fab to bring out theirs

You guys really think that filter gives you 15hp? Like an honest question lol. Just seems ridiculous doesn't it?
