Cam questions on turbo and N/A

Mike,

In my Coupe GT I did the MC cam in it, I can't really say I noticed a 
difference, I think I just revved the engine harder afterwards to justify the 
work.  A very noticeable difference was felt when I upgraded to the Elgin 270 
cam, much softer bottom end, but that baby screamed all the way to 6800 RPM.

Also, makes sense about the NA cam giving some power on the turbo cars, the 
increased overlap will definitely help at the high RPM range.

<< Hey list,
 Of all the silly things I've heard....
 So a few people suggest that the turbo cam in an N/A car will give a slight
 increase in power, especially on the top end. Huw tried it if I remember
 right and he said he felt some gain.
 The thing that is making me wonder though, someone told me that replacing
 the MC cam with one from a JT (N/A 4kq) gave them more power in their turbo
 engine. So the turbo cam gives more power in the N/A cars, and the N/A cam
 gives more power in the turbo engine? HA why didn't Audi just install them
 like that at the factory!?
 I'm still not sure about the N/A cam in the turbo engine (seems the overlap
 would be wrong, but what do I know), which is why I ask here. Anybody have
 any insight?
 Thanks
 Mike
