well that answers why a 300c runs nearly similar times to a Caddy CTS-V. So now knowing and keeping that in mind.....

why on earth would anyone buy at 400hp caddy cts-v to have it put down no more than an fbody did? And when you can have for 15 to 20k less, a 300c loaded up the wazooo, more room, that runs nearly identical times.

 

Is this just a bad apple or is this pretty universal for CTSv's?

If so we gotta ask why.... What made them restrict the LS6 so much?

 

 

Because some people might think the CTSv looks great and some people think the 300c, as odd as it may sound after reading this board for ... 4 minutes, looks like death.

The dealership where my friends Mom got her CTS said they cant keep the CTSv on the lots. Hopefully GM didnt **** this one down their leg, it'd be rather disappointing if this is common to all cars.

I didnt read the thread past the first page, but Im wondering if something with this beefed up version of Sigma is eating all the power, or if it's the air intake/exhaust that's choking it to death. I guess we'll find out soon enough.

 

CTSv runs in the low 13's

300C runs in the high 13's to low 14's

The 5.7L Hemi has 390tq and the 5.7L LS6 has 395tq

 

Nearly identical times? I guess if you consider 6mph and almost a second ET to be "nearly identical" you have an arguement.

The 330C is not near the performer the CTSv is...

 

I figure if the 300C had a manual tranny it'd run low 13s too.

Geez, GM is shortchanging CTSv owners to the tune of about 30hp. Makes the '99 Cobra look like a good deal.

Wow. Funny how the times are a changin. GM is the new the king of overrated on the block.

Can you imagine the conversation at the final testing?

Engineer : "These things aren't making 400hp."

Marketing : "They're Cadillac owners, not Z28 gearheads. Nobody's gonna dyno their CTSv"

Engineer : "Uh....ok"

 

How many CTSv owners dyno thier cars? I would say select few. Most will just romp on it to impress their friends and then say "Ok, that was enough I peed my pants a litte." And just cruise with it most of the time. I know I haven't dynoed any of my cars but that doesn't mean I don't enjoy the performance they bring.

 

hp_nut does have a point (although he came about it in probably the worst way he could have). It doesnt really matter it they're not putting them on the dyno, they are supposed to be making 400 hp and the owners are victims of false advertising if not.

If it is the same LS6 in the Z06 as stated in the original thread, then either an air lid or some sort of new exhaust should bring the hp level up to about 340 rwhp, or 397 hp, which unlike the 99 Cobra or more recently Madza's RX8 overstatement, should only be a $200 fix per car and the dealers should be able to install this stuff very quickly. If GM hops on this asap it shouldnt develop into much of a problem, but if they drag their feet it'd be a bad blow to a Cadillac that was headed full steam in the right direction.

 

AMEN to that. The more I see of the 300c on the street the less I like it. One of the key aesthetic problems, to me, it's too-short overhangs. It looks a little like a farmwagon, its wheels pushed way too far out to the corners. bleah.

As for the CTS-V. Why would it be low? It's common knowledge the FBody LS1 is underrated by 20-35 crank HP. Take that engine, add LS6 heads and other tweaks. It's not a big reach up to 400.

 

not to totally hijack the thread but...
i do agree the 300c (300) doesn't look too good on the street from the ones i've seen
i think it looks great in the commercials but on the street...it's another story
i guess i'll have to see one up close and personal

on the cts-v note, i think they should have 400hp and not be overrated, but at the same time, how many cts-v owners are gonna dyno them?
it just doesn't seem like something that would happen often

 

All I know is that if I spent $52K on a car that's supposed to make 400HP, it damn well better make 400HP . . . or I would be one extremely pissed individual.

Especially in light of the difference in price (gouge) between the CTS and CTS-V.

 

Well, here's my 2 ¢ . Mercedez transmissions (auto) are very efficient at transferring power to the wheels. Stock C32 AMG, 349 HP sport sedan, was running 13.2 at the local drag strip. That is LS1 times, even better, with auto tranny.

Manual is providing more power, sure, but think of the difference between FBody auto and manual. Most autos can run BETTER times, but I am willing to take the worst case scenario. Say they are slower. It is not more than 2 tenths though, so let's assume that 300C with a manual will run 13.6 to 14.0. impressive, very impressive considering it's a 4000 lbs car.

Another thing with CTSv. Same engine as the Vette. 900 lbs more weight. Running roughly .8 - 1 second and 8 mph slower than the Vette. To me, it all adds up.

It would be really good to get some more CTSv dynoed. And I'm not talking 2 or 3, but let's go with a random 10. If the numbers were still what they are, then I'd have to wonder why, because the car lays some good times with its only "365 HP".

 

BAM! Thats the bottom line right there. That car would be back on the dealer lot and I'd be demanding my money back.
