I will say this as an argument. If I can gain reliability over the stock ihi or a competing company it is worth it to me. Obviously, this isnt for the guy who wants to be the fastest person. The whipple 3.8 will out perform this blower no doubt. But for the guy who wants what I hope to be an 8.5 capable blower (maybe faster) it is a good spot to be. Or someone who wants to run the 9.0 class this will be a great option.
I do a fair amount of street miles. More then most people who run similar times to me and I make a ton of passes when I go out and test.

I have a 2650 on order. Placed it yesterday morning. Curious the kind of track numbers it will put down. I'm excited. I asked Greg at Kong how hard can I spin the blower he told me as hard as I want. The Magnuson used an Eaton rotor pack and people spun those extremely hard. It was the Jackshaft tube that kept breaking on those. So it is sounding like this thing will be reliable and take abuse.

The main draw for this design is they are symmetrical 4 lobed rotors--so both spin the same speed--so should be much easier on the bearings than the 3:5 IHI design which tends to destroy the male bearing if pushed too hard.
I don't know what the efficiency comparison is between this rotorpack and the IHI rotorpack. An rpm per rpm psi comparison between them would be nice to know.

SDG will call you and talk to you if they find issues and are very knowledgeable. They won’t just slap your stuff together and send it out the door. SDG is hellcat only. Stick with them, use no one else (big name wise). Have been around for a long time and dealt with most of the names in the business. SDG are the only ones I’ll trust now.

agree the SDG snout and plate are fantastic parts, I am never doing anything else to my IHI except selling it and going with their setup when the inevitable happens again for bearings going out....bushings I can handle, the rest is just something I have HAD done enough times to check off ANY BOX

Yeah but turbos are a pain in the ass to deal with. I learned that lesson a long time ago. Reserve those for the racers trying to win money.
...........Or win races! I agree that they are more work to setup but once you get them done and keep maintenance up on them, they work.
Not nearly as much fun at sane speeds on the street either.
It depends on how you set them up and how you size them. A big turbo car won't run like a blower car on the bottom end but if you know that you're not going to drag race (street driven), you size the turbo one or two sizes smaller or throw a twin scroll turbo on and you have a nice little, happy street car that you can adjust boost on. I know that you can adjust boost on a blower too but it's not as common as a turbo and doesn't work as easily as pressing a button (or using C02) on a turbo car.

I tend to favor a turbo setup over any other type of forced induction and it's just my opinion.

whipple style generates less heat than the TVS style
You got data on that?
Yes this is actually correct. The 2650 bricks are massive. IAT2 temps actually go down as you make pulls with it. I have logs upon logs seeing this with my own 2650 on my ZL1. Vs the stock blower that would sent temps flying.
As far as heat goes Whipple has all these designs beat for one main reason the others designs can’t do. The Whipple in bypass mode, ie idle, cruising around, etc is passing bypass air through one stage of cooling keeping the blower housing and rotors cool, all others only cool the air going through into the engine and recirculating already compressed air over and over and over at idle and part throttle getting the blower and rotors hot. The smaller the pulleys, ie more air, the more part throttle recycling of hot air goes on the hotter the blower gets in part throttle running.
