Received my Kong 2650 last week! I have only seen the big shops installing these right now so I figured I would share my experience.

I got the supercharger mounted yesterday. The Kong does not use the long bolts that go through the body onto the heads like the OEM supercharger does. I would say that's the most "difficult" part of the install.

Also, the 130mm throttle body does sir further forward than the OEM or the 108mm I previously had so the intake tube mounting will be slightly different but not a big deal. Waiting on a few things to come in but should be starting it up soon.

Smallest pulley I've seen 👏

Some notes on the install here that make it different from an OEM install.

The kit comes with a quick disconnect fitting to go between the OEM fuel rail fitting and the fuel line that runs behind the supercharger. The placement of the fuel rails on the 2650 is wider than the OEM and this makes up for that difference.

I had the 5/8 spacer on my ported blower. I had initially tested closing the hood with the intake off and it closed just fine, however, after installing the intake, I noticed it clashes with my bwoody tube. I will likely end up taking the spacers off and just using gaskets if I can't find a hood that will give me the clearance I need. The hood closes if I push hard but not correctly. So I think I can conclude the 1 inch spacer would definitely not work here.

Here it is mostly put together. I did my first few test pulls. It made 19psi on the 2.75 pulley and that is at an elevation of 5200ft. Peaks at 19psi in 4th with a 6500rpm redline. So for those of you at high elevation that's a good data point when picking out your pulley set up. Sea level would probably make another 2-3psi on the same pulley.

Nice!! What’s your engine displacement? Any Headers cam etc.?

That Kong 2650 is looking super efficient.

With their smallest pulley, the 2.35", at redeye WOT of 6500 RPM and with an ATI 10% lower the 2650 rotors are spinning just under 25k RPM--slower in fact than the IHI male rotor on a stock HC setup with stock lower and 6250 RPM redline, and yet putting up Whipple 3.8 levels of performance...

It's much easier to source bearings that can handle 25k RPM than the 30k+ RPM some are pushing their IHIs to--so these Kong 2650s (assuming they did put in good bearings), are not likely to eat themselves when pushed this hard. These units should be very durable.

Catching attention and rightfully so.
