Cam or s/c
Idiots... any block can handle a certain amount of psi from any charger especially a supercharger. In my honest opinion a supercharger is loads more efficient than a turbo, but that's another story all its own. Anyways a block has a safe psi range, and as long as you stay below that range you are fine (max psi). Also when you are driving normally you aren't producing more than a few psi as compared to the max which is applied only at WOT. If you drive a vehicle like you stole it a supercharger or not the engine will be completely ruined before too long.

Wow. Ok well its true every part in an engine has its limits. Our rods for example are rated at 400hp @ 6000rpm. To make more power than that you have to back away from the 6000rpm mark or replace the rods and pistons. I'm at 600hp but my shift points are at 5400rpm and my soft rev limiter starts at 5600rpm just in case. As efficient as the Whipple is it cannot match the efficiency of a turbo. A turbo does not require HP to turn. A blower does. Anywhere from 50hp up depending on the blower. A blower however can produce boost much quicker than a turbo. A twin screw for example can produce full boost at 2000rpm. No one else has that ability. Also under normal driving no boost is made. Bypass valves whether electric or vacuum operated prevent this. Boost is made based on engine load. Similarly a turbo only produces boost when enough volume of air comes through the exhaust to spool it up.

Well if we are gonna argue turbo vs s/c let me throw in my 2 cents... Nitrous better than both.. Cheaper, easier to set up, easier to tune and less wear and tear on engine parts since you only use it when wanted. Superchargers always have drag on the engine creating load even when not in use... Turbos are hard to make efficient on most applications especially with universal kits since exhaust gas does spin the turbo but it is actually the heat that really gets it going... Nitrous dry shot will give you the same gains of a blower or turbo for about 1/4 to 1/3 the cost. It may be cheating but im a cheap ***....
I was on your side... Like I said superchargers are better IN MY OPINION. I hate turbo lag and inefficiency and believe superchargers are honestly better for Gasoline engines, but once again that is in my own opinion. I also agree with you that at a certain RPM no boost is created, but it will kick in before WOT, correct? I'm not trying to be a smartass and I appreciate the information on boost.
As for Whipple paying me...don't I wish lol. I recommend them cause after months of research and homework that's what I chose based on what I learned. The one flaw in the Whipple kit is that it uses our stock 24lb injectors. Now keep in mind Ford approves this seeing as how they make the tune for Whipple and this is a Ford Racing/Whipple blower. As I stated earlier its a horrible idea. It runs the injectors at 90-100% and runs the fuel pump very hard to bring rail pressure up to 67-70psi at wot. Again all approved by Ford. I even called Ford to speak with them about it. But then again they approved the cam phasers and these cheap *** injectors to start with. It's an easy fix though. A set of 39lb injectors can be had for $250 and get a custom tune. You will get 30 more HP out of it this way and you will be much happier. Trust me tunes sent from any of the blower companies suck.

As for drag on the motor all the time...blowers have come a long way. The Whipple and Saleen create a 1 HP draw when not boosting. The Roush and Edlebrock blowers are just a little higher along with the centrifugal blowers. I hardly call that putting load on the motor.
