Upgrades are finally complete (for now)

[KentState]

What started this summer as just wanting a air intake has turned into the addition of a pulley, thermostat, headers and a tune. Later this year, I will probably looks at a heat exchanger, cam, heads and a larger pulley.

Parts:
9.17" lower pulley
160 degree themostat
AirAid intake
Kooks headers/x-pipes w/cats

Here are the dynos for the first pull, after pulley/intake/tune and then the final after headers/tune.

Give us a YouTube vid with gratuitous revving!!


Does the car throw a cel because of the exhaust?

No. Kooks has been making them properly for while now so that it doesn't throw a CEL. I know that American Racing has updated their design to a more optimal location. I will try to get a video of it revving later in the week. Luckily, it isn't overkill when cruising, just a little louder, but really screams when you get on the gas. I was plugging my ears like a little girl when they did the dyno pulls.

No video? Someone ban him now. Right now. 😛

I would love to be in the 500hp club. Well done.

 

[RavenSEAL]

Dammnnnnn, 500 horses??

NICE!

keep in mind that's power to the wheels. the power at the crank is usually given a fudge factor of 10% or so. so the real power is something like 550/0.9 ~ 610hp.

That's ricer math.... Most just use RWHP numbers. 😀

Makes them feel better about having only 100 on the ground, even with V-TEC YO!

It always turns into a debate over the actual loss % too. Some want to use 20%, others say 10%, etc....

According to the baseline, the car is around the typical 15% loss. That's also pretty consistent across the various dynos I've seen. The average over at the Cadillac forum is around 470hp and tq. Going by that fuzzy math, the car should be around 650hp/670tq. The real test will be the track this spring.

you really can't judge that unless the motor has been out of the car and on an engine stand.

Not familar with the CTS-V, eh?

 

[Howard]

How do you like the car other than for the speed?

 

[KentState]

I like the car all the way around. I had an '08 CTS and was very happy with it as well.

I always use RWHP/TQ if possible.

 

[natto fire]

Wow, ~460 ft-lbs at 2500 RPM, what are you usually turning in top gear freeway cruise, and is your mountain of torque named?

 

[alkemyst]

Yeah and in the end pointless.

If the CTS-V was a bit lighter and tossable plus not in the 18's for MPG at the high end, I'd be in one of them or a M5.

In the end I love my M3 though...need to figure out which way I am going under the hood.

I turn around 2200 rpms at 70mph. The torque has been named Tire Smoke.

I'd like to have either, but i'm too cheap. Hell, my camaro is really too rich for my blood. D:

i am famaliar with it. wat i meant to say to OP was that its putting down over 550 hp to wheels while looking stock. even the wheels are stock, it looks like a completely stock cts-v. i love that in a car. stock looking outside with power way over stock output.

15% loss for RWD
25% loss for AWD
