It depends on how you look at it. The intercooler does not affect the efficiency of the compressor directly. It does affect the overall efficiency as a system though. It's a compromise situation. You loose boost running any intercooler. But if the intercooler increases the density of the air charge to the point that you still obtain an overall increase in power then it has increased the efficiency overall. On a street driven application an intercooler is always desireable. In race applications it is a different matter. There are Pro 5.0 cars running 30 psi non-intercooled as that's how they've found the most power. They are also running AFR's in the 8's or lower.

 

One question to the "panel" I sort of suspect I know the answer but I would like to hear it verified. On a new vehicle, I would assume the addition of a s/cer would void the warranty. Am I correct?

 

No, products don't void warranties.. People do if they are allowed

Wow,,I never herd that one before!

I do not understand this comment. Please explain

 

The law says that the dealer must prove that a product caused direct damage to another product thus voiding that items warranty.
Innocent until proven guilty..........Only in a dream

The reality is that you have to prove the product did not cause the failure of the item in question.
Guilty until proven innocent............The real world.

If your brakes fail, trans goes out, the dealer cant just pop the hood and say... supercharger.... that caused the problem... Warranty voided...since they actually dont know untill a tear down of problem area..

 

I doubt any with a roots but more so with the twinscrew.

 

Just FYI KB is notorious for not updating there page. I do know they are suppose to release several (10-12) new kits are so in the very near future. Now not sure if some are going to be intercooled or not though.

 

That is one of the first things I noticed after the swap. at 60-70-80 mph (I lived in Houston for a while, rush hour traffic flows at 80-85mph ) I could ease into the throttle and I could feel the pull without having to kick down. Same when towing. Now it's more fun to kickdown and pass but you don't need to IMO, if you are driving sensibly.. haha !

 

No it will not change the efficency of the blower but it will increase the efficency of the "system"! The cooling mechanicsm is centered more around making more power, or efficient power with the charged air. By cooling it you are making it more dense allowing for a better burn, more volume, and more timing.


I understand, but it's easier to compare two differnt blowers by keeping as much of the inputs the same as possible and seeing what the output is.

 

I think what you saw was a result of a lean tune more than the fact that air wasn't hitting the blower directly. I could be wrong but charge temps aren't directly related to engine temps but indirectly through the burn.

 

Some but not all. For example, if you have a Roush certified technician install a Roush supercharger and you don't change it up, you do have keep a warantee but from what I understand it is no longer a Ford warantee but covered by Roush.

And it is true that they must prove that modification is what caused the failure but most of the time they can run legal circles around you and you can't find a way to defend yourself.

 

It's true with all similar setups. You get a pressure drop across a radiator/intercooler. Pressure is related to temperature. Pv=RT where v and R are constants. In simple when you give up T you are giving up P also.

 

Then you learned something.
