CTS-V dynoed
#41
I think the assumption is that once you spend $50K large for a vehicle like this you're probably not interested in modding. If 1/4 mile times were all you were concerned with there are plenty of donor F-Body's or used Corvettes to do this with. However there will ALWAYS be exceptions and I may be one. My first V will be for sale in July. It will be under 10,000 miles and will be well maintained. I should be able to sell at a profit as my purchase price was well below MSRP and far below the dealer markups. We'll see.
The second V will be my "keeper". I will definitely open the exhaust, intake and experiment with tires. I believe 275/40/18's will fit all the way around. Cam and heads are NOT out of the question. As with every car I've owned my mods will be carefully thought out and the providers and installers will be the best available. I'm also sure that amongst the great parts available there will be some crap. Some things never change.

That assumption about the cost of the vehicle and modifying it are not really valid. I know guys with $50K Hummer 2s with heads/cam and blowers. That also goes for the 1000s of $40-50K Corvettes out there that are highly modified. No matter what car a hotrodder can afford, he will always want to tweak it to get more. People do not buy a V8 6-speed CTS-V because they look cool, they buy it for the extra performance.
Make my CTS-V with a 427ci under the hood and 18" HRE wheels please

Yeah, I would have to agree to some point with the above post stating that this particular car may have some issues or simply not be up to par for some reason. I would wait until you have a chance to dyno at least 3 or 4 of them to get any solid expectations of what they are producing across the board.
At least the published #'s don't support 319 rwhp... more data will tell the truth though. Hopefully the owner will want plenty of mods and you guys can do them in stages to find out what the car reacts to best. Thanks MTI. Patrick

Personally if I bought a claimed 400 HP car and dynoed 319 at the rear wheels, I'd be contacting GM about a false advertising lawsuit....wait a sec....sounds awefully familiar to some Ford guys I know......

Simply plug in the weight of the vehicle as tested - 4,070lbs. in the case of R&T's CTS-V
Your desired trap speed - 109mph in R&T as well.
This equates to 420 hp needed to propel the vehicle to the top end.

Where did you come up with 420 hp? If you try it on a 105.5 mph trap speed the hp equates to 372.99604 hp.

Oops, I was putting a comma in after the 4 in 4,070. So what formula are they using? It also states at 105.5 mph trap speeds it takes 381 hp. Try taking your car to the track and see how it runs, maybe you have one those 109 mph CTS-V's.

I may go with my GTO buddies but only for fun and probably only once. My drag racing days ended first with my 67 Chevelle 454 yadda, yadda, yadda. They were rekindled with my 97 Anniversary Z warmed over LT1, 4.11's, yadda, yadda..... I'm done with that for awhile. My weekends are for soccer games now and I prefer it that way.

40rwhp from headers and exhaust? Maybe if you use a plasma cutter and do some creative bodywork to get the headers to fit?

I agree with u... Intake and full exhaust work could make a huge difference. For example my LS1 dyno'd 292rwhp 313rwtq stock which is dissapointing. After LID, Headers and Catback i gained 56rwhp 50rwtq and went from 13.4 at 106 to 12.7 at 111mph with the same 60ft.
Check the graph here http://www.msnusers.com/CarsRelatedG...hoto&PhotoID=9
Look at dyno dynorun#002 compared to dynorun #008.

I am waiting for a nice decent intake with maybe a mellow catback just to hear a little more, other than that no other mods, do some tuning and the car will have plenty of power.

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.

That's what really draws me to these new cars, the overall feel and performance.

Hot Rod,
You're all over my posts after stewing for 9 days? Man you're on top of this one. Also, don't apologize for name calling it's typical and I'm used to it. Plus anyone who signs their post with "douche" is someone to be taken seriously. Will you sign your next post with enema? Keep 'em coming HR, your posts are informative, well thought out and a joy to read for all.
