1st) Not all heads and cam setups = $5000+. I can port my own heads and a cam that works with the stock springs and lifters is $450 bucks and I can install it all for FREE + head gaskets. So it "ain't the same price". Of course "your price will vary"... it just varies a lot more on the heads and cam than the supercharger which will ALWAYS be in the $5500 to $7500 range.

2nd, FI, is a huge increase to torque and this can lead to drivetrain failure, which is NOT cheap. Sure there are lots of caveats like I have an auto, I only run street tires and never will track it... Clearly the hedging is an admittance that with traction and / or a M6... stuff breaks at 650 ft lbs. Said stuff is expensive.... and should be factored in with a supercharger in relation to usage.

3rd, longevity of the ring lands on this 11.4 DI engine is an unknown. I'm not saying it is going to fail the first drive down the street, but clearly especially under road race conditions, there could be longevity issues. In all cases NA is going to live longer and yield closer to stock OEM longevity, given any reasonable cam / red line NA.


4th, NA stuff can be added piecemeal, which is usually better when the commander and chief is looking over the budget.

5th, NA stuff for the most part works with a supercharger

6th, we all know just about NOBODY just blots on a supercharger and is "done"... right.. LOL, I know that is what you tell the spouse, but deep down power is addicting.

so do heads and cam = supercharger? Depends and obviously it depends on a whole lot.

My Challenger was supercharged and so is my 2015 Civic SI.
