Little fun after Cars & Coffee this morning. Mexico coffee shops ftw.

Is that the outcome you expected?

Awesome caddy

More or less. It was still pretty close (imo), but I wasn't really expecting to pull on him. I was surprised my car jumped on his like it did.

Do you know how many times I have read on different Mustang forums/pages that the CTS-V isn't all that fast and that it's not even close to being in the same class as a vette? Of course not, dummy, it's a luxury sports car, but damn it certainly does do some amazing things for a 4 door!! Even its track times have broken in to "supercar" territory

Nice kill.

Yea, I agree. I'm a mustang fan (previous car was a SC'd s197), but I've grown to realize how quick these V's are with minimal mods...while still driving like a stock Caddy. With that said, the new GT500 motors impress me more than the LSA: Intake, pulleys, and exhaust and they're making 700rwhp+ on pump gas. Impressive, imo. I have a mild cam, e85, and a maxed out blower and haven't been able to break 700rwhp.

Local here has a 2013 GT500 with a little over 700rwhp....our traps are identical and I might ET 1 or 2 tenths faster.

Also, a 40 roll is the sweet spot for my car. Lets me use 2nd gear while pretty high in the revs. He says a 40 roll sucks in the z06. We'll probably do a 60 roll rematch....as well as with his nitrous. I'm thinking he is going to yank me pretty bad on the spray.

 

[da5deuce]

DAMN. V puts in work.

What is the elevation where you are at? N/A cars struggle more so at altitude than F/I cars.

i have a bolton Z06 35-40 is kill zone in 1st gear i dont the z guy can drive do u know the trap speed on ur ctsv it sounds amazing

We're at a mile high.

Here is the same z06 (same mods) vs. a 720rwhp GT500 KR.

those races seem way more closer to how they should be damn ur ctsv hauls ass then but i dont know much about elevation a mile high is high im about 800 foot above sea level where i live

Yea, mile high elevation *definitely* sucks up a lot of power...more than 100rwhp for a car at my power level.

But, the difference between blower and NA loss isn't as big as many people believe. An NA car loses a solid 1 second up here, where my car loses about 8 tenths or so. So yea, it might be a bit closer if these 2 cars ran at sea level....but shouldn't be a significant difference. Now, an electronically controlled wastegate on a turbo car with enough turbo to make up for altitude is a different story. Turbo cars *generally* see closer sea level vs. altitude 1/4 mile numbers....of course, that depends upon a several factors.

 

[UBNZO6D]

it's been my experience that because of the weight difference that the C6 (sold) will yank a Mustang with 150 more HP.

It doesn't add up. Going by those races, your car would DESTROY the Mustang even though the Mustang is making more power and weighs less?

They probably did a higher roll. I'd bet my car and the z06 would be a lot closer from a 60 roll. Like mentioned, the z06 and my car trap within a couple mph. A real race (dig) and preferably at the track would be the best way to compare all these cars

Great point. I am in the same situation as you with Denver and Bandimere where DA's get over 8500. One thing I have noticed with my two previous turbo cars was when the boost came in. Compared to being in San Diego my boost in Denver was 1000 rpm behind. Meaning at 3,000 rpm at sea level I would see 15psi and in Denver I would need 4,000 rpm to attain that same 15 psi. I am back in a turbo car with the RS6 so I'm happy. AWD and temps in the 20's the car is running awesonme.

All of my normally aspirated cars that I have dyno'd here have had a 19% or 20% correction factor.

Yea, altitude sucks for numbers, right?!

Bandimere is a little higher than our track, but it's usually a bit colder. I notice our DA's seem to be pretty much the same...sometimes bandimere is higher, sometimes we are. I've seen nearly 9000ft during the warmer months :O

A few weeks ago when I finally got me a 10.99 the DA was 'great' at 6700ft, lol. One of these days I need to get out to Texas or Arizona and see what it can do with some sea level DA's. My guess is a 10.2 with some great weather.
