So what is the deal on top of the plenum in this picture. I found it at Summit Racing.

The kit you found, even though it says it will fit the new mustang, is for the 99-04 4.6 (notice the direction that the throttle body is facing). That kit will not work on the 3v 4.6.

 

when you have a nitrous kit that taps into the fuel rail that is a "wet" system correct?

So if you are looking into staying under warranty the easiest way, wouldn't I want to go with a dry kit so that it can be taken off incase I had any engine problems?


Which one is safer for our cars? wet or dry?

thanks

 

Actually the ZEX and NOS wet kits just use a spacer on the sensor in the front of the fuel rail to get fuel. This spacer can easily be removed with two bolts and put back to stock.

 

not always true. a centrifugal blower adds boost progressively, begining around 2000-2500 rpm and reaching full boost at redline. below 2000 rpm there is virtually no boost, so the engine isn't "always boosted"
