Cadillac CTS-V - went to dyno to day

I'm happy with only 5.5lb of boost

As you should be! Those numbers seem high for only 5.5 pounds. Are you all stock motor? Nevertheless congrats, is it a new install or just new dyno?

whats your setup?

yes I'm on stock engine beside cam,intake,and header

Specs on cam?

5.5psi of boost and that sort of hp. If only diesels worked in a similar way, but no I need 55-60psi to eek out 600's.

yes...and then only managed 1200 ft lb of torque...damn dirtymax

It's seeing things like this that make me think twice about "vowing" to keep my engine stock..

trust me, keep it pretty stock...even though you got one with a Procharger, haha.

since you are coming from mustangs, it will surprise you at how "slow" these cars are with 500+ hp. The V1 platform does not like bigger numbers compared to other LSx cars. It suffers from poor engineering and sub par parts. I have just minor bolt ons, and the car is extreme tempermetal. I could not imagine the shit storm that would happen if I keep modding. But mine is also a DD now...and I am trying to sell it. So I am done modding, and just waiting to get into something faster, and nicer.

What do you have supplying the boost?

What do you have supplying the boost?

procharger d1sc, 4" intercooler, boost cam, fast 90, obx headers

So true, these cars can be as tempermental as a child. Drives me nuts, atleast I dont have to worry about the duraskank ever breaking down.

To be completeley honest, most of my time and money is devoted to my racebike. This thing actually makes me happy at the prices I pay for top notch brake and race parts! I'll swear I'll never bitch about the cost of running a racebike again.

If it makes good, reliable, safe power for when I want to get away from the bike, I'll be happy. Seeing the OPs dyno chart tells me I will be, with a few more small tweaks and a few hundred hours overtime at work to pay for it all....:(

Nice HP but I expected a little more torque.

Horse power is equal to the product of torque and rpm's divided by 5250. That is why on every dyno graph the hp curve and tq curve intersect at 5250 rpm. When was the last time u took ur duramax to 5250 rpm's?

I'll go change my mapping and see what happens haha. If you could build a rotating assembly that could handle those sort of pressures, and find a fuel system that could maintain 26,000 psi in that range it would be something. If I ever get some head studs and new sticks in that thing maybe i'll try for the 900 mark.

Congrats!! Can't wait to see the rest of the car finished :nod:
