I finally got a Dyno test on my build. Chris and all the great guys at CBM in Colton Ca. Tweaked my 2017 SLR today and have it humming.
Final numbers are
265HP at the wheel and 220 pounds torque with 6 pounds of boost.
That’s with the ProCharger Supercharger,
The DDM Works high flow fuel rail,
The 1320 V-2 Headers,
The Welter 2.5 Catback delete Sidekick pipes,
The DDM high efficiency radiator and oil cooler w/ relocation kit.
Plus all the DDM Dress up in Orange Madness
Stuff under the hood. Hoses, Coolant overflow tank,
Valve cover and Coil cover, caps and more.
Along with my Wycked Industry Hitch and the Bushtec SS Cruiser trailer I’m just about ready to take my trip in May to the Vietnam Memorial with the
RFTW group. Going the max Ontario CA. All the way to the Wall Washington DC.
Gotta thank SlingMods for their great business and all the stuff they helped me acquire.
IE. BullitSpeed, Twist Dynamics, NavAtlas, PRP Seats and TricLED.

Looks great I'm considering the Procharger kit as well for my SLR soon. Are you concerned about the longevity of the stock bottom end with that setup?

Nice Sunlinger! Enjoy your trip to the Vietmam Memorial. Twenty + years ago I had the honnor of being an overnight guard at the traviling wall when it came to my area. It was a beautiful, humbiling experience. I wish that the youth today would take the time to feel the emotion of those who have sacarificed along with the family and friends who have also given. Thinking back brings tears in my eyes at the moment. If you served many thanks for our freedom.

As long as you run the required minimum octane of gas, the stock bottom end should hold up. Our supercharger kit makes more power than the Procharger and we have not had any engine failures with our base supercharger kit, so you should be fine.

Super nice! Are you still using the OEM Clutch? If not, which brand are you using?
Stock clutch will typically hold up to/around 300hp/300 ft/lbs of torque. It depends a lot on how the vehicle is driven though and what type of tire is in the back. Stickier tires put more stress on the clutch when doing hard launches.

Can you tell me the size of your slingshot crank pulley and what size pulley you are using on the ATI CS-1? I'm interested in the ATI CS-1 for a similarly sized application. I'm curious how fast you're spinning the CS-1 to get 265whp.

Here is info I got from ATI:

On the Slingshot kit we use a 5.00” crank pulley and on a stock car and our standard boost level it comes with a 4.13 pulley at 6250 engine RPM. This puts blower speed at 62,800. Max blower speed is 80,000 RPM.

Has anyone tried running a smaller SC pulley?

Fairly surprised at 265whp and only 6psi! Procharger says 55% more than 165hp at the flywheel at 8psi which would be like 268 flywheel hp - could you clarify?
