Default Gen 3 CTS-V + F1X = 1,429hp

What a way to head into the weekend with this 2017 Cadillac CTS-V laying down a solid 1,429rwhp and 1,151rwtq on our chassis dyno!

Our team here have put in a LOT of hours on both the mechanical and tuning side of the build this year with this project and happy to share these huge results. We'll be heading to the track very soon and look forward to sharing our ET and mph results on the build

For those who haven't been following the build, the combination is as follows:

- ProCharger F1X supercharger and 10-rib bracket
- Late Model Engines 400ci forged long block combination
- Hydraulic roller valvetrain - Non VVT
- LME billet intake manifold with port injection rails
- Prospeed Autosports ACM secondary injection system
- Professional EFI Systems Inc. I-boost controller
- Kooks Headers and Exhaust long tube header system and connection pipes
- DMH Performance cutouts
- 15" conversion kit
- Weapon X Motorsports line lock kit

Vengeance Racing custom parts include:
- 4-point roll bar system
- Parachute mount and cable system
- Low-side race spec fuel system
- 1700cc injectors
- Air to water custom fabricated intercooler system
- Billet valve covers and coil relocation

This combination was 100% built and tuned here in house with a lot of love from the entire team here. Stay tuned for track results coming soon!

Power graph might almost suggest a little up top ?

Maybe no room for a 12 rib ?

12 rib with a strong spring tensioner will handle a lot.

Thanks for all of the kind words guys! We have zero slip with the 10-rib setup and seeing 35psi at peak. We use a similar setup on a few C7 and C6 Z06's as well making about the same on power all with 10-ribs with no issues, and a lot better belt selection.

Having done it in the past, I cannot see any good reason to use cogs over a good ribbed setup.

Perhaps on drag only maybe...but for anything else. no.

Awesome build.
Guessing it would keep making power with more RPM, is it limited due to the hydraulic or just a self imposed redline?
Curious as to why go hydraulic on such a hard core build...street cruises?

Definitely not an all-out drag car. It came to us with 1,600 miles and we will be providing more about this featured build shortly. Custom cage and all the right parts. Stay tuned

So a 4-bolts per cyl block held 35psi?

Great numbers! How fast were you spinning the F1X at max engine RPM?

Yup, they hold it with a turbo too but as far as how long is dependent on size as 35psi from a 76 or 85 may be fine but 35 from a 100mm blows the heads off. But with a procharger holding peak PSI over a shorter RPM span in comparison I'd guess it would last a lot longer assuming the crank stays in place.

hmm...35psi from a 76/85. works but 100mm wont. Can you guys share some of your results? T4 or T6? What size hot side? Backpressure for each?

It was a stock block with aftermarket sleeves, aftermarket internals/bearings, and head/main studs.
