CTS-V dynoed Just a few hours ago I witnessed a beautiful, paper-plated, silver CTS-V dynoed at MTI. The car is definitely the nicest car GM has in it's line-up.
BTW, anyone wanna guess what this Silver Terror dynoed?

Since Leo is SLOW to answer, I'll do it for him.
It dynoed 318 - 319 rwhp. No, that is not a typo. We were just as disappointed. I checked the programming and it is virtually the same as the Z06 Vette. Exhaust is not too bad but there is a huge resonator in the middle of the car that merges both pipes together. Must costs some power there. Dropped the air box and put a K&N cone on the end of the MAF and only picked up another 6 rwhp.
MTI Stage II heads/cam are next...

A 400HP car with a manual transmission only manages to get 320HP to the wheels?
Can there really be that much loss through the driveline, or is it the power overrated?

I was looking at the car on the lift, the exhaust is a big problem, I guess later in the year they are going to offer a Corsa exhaust as a dealer option, rims, slotted rotors, carbon fiber stuff, etc...
Those #'s aren't impressive at all, but with a few tweaks of exhaust system and what not it should fly........especially once you start digging into the motor.....

The exhaust does seem a bit restrictive.

318 HP is impossible! Road and Track tested the CTS-V to a quarter mile time of 13.4 @ 109 mph. This beast weighs 3900 lbs. for crying out loud! You may be able to run 13's with 318HP but NOT with IRS and NOT @ 109 mph. I suggest that the car you dyno'd had issues.The exhaust is definitely not ideal. It's a 2 into 1 resonator (with mixing) back out to 2 with the mufflers tucked neatly under the trunk similar to the 'Vette. This is my first "V". I will sell this in July to buy another to keep. First mod' will be to cut out the resonator. I would expect at least 10hp/10tq pickup and a lot more LS6 noise. Good noise.

I've read the articles in C&D, MT and R&T. My statement still stands. Someone explain to me how a 3900 lb. car can hit those numbers with IRS and runflats while generating only 318 rwhp. It simply can't be done.
Road and Track also has it hitting 100mph in 11.4 secs. That's on par with the following cars:
Car - 0 to 100mph - Horsepower
Vanquish - 10.8 secs - 460
M5 - 11.3 secs - 394
Ferrari 550 - 11.1 secs - 485
S-Type R - 13.0 secs - 390
Maserati Coupe - 11.4 secs - 390
These cars all have similar girth and I doubt highly that their horsepower ratings have been inflated. I also doubt highly that GM could engineer a vehicle capable of this performance with only 318 rwhp. If they could, just imagine what all the stock Z's would do with solid axles and radials.
My BS flag stands.
