OK, that's my case.

Any takers?

 

Interesting. That's a really good read on the RADIX. Where did you egt that from, I'd like to see the pictures too.

 

Yep....do you have one?

 

which read? I'll post the link no problem.

 

damn more grip, you like to type.

 

oh I can copy and paste with the best of them

 

The first one mainl, but both links would do.

Cliff notes would be great

 

Boost "seen" is dependant on the volumetric efficiency of an engine. The reading on a boost gauge will never constantly read what the blower is pulleyed for. Boost is a measurement of back pressure. It can be misleading when manufacturers state full boost at any rpm. One assumes a 5psi pulley will show, on a boost gauge, 5psi at any rpm. Once you're wot a positive displacement blower will deliver its "full volume of air"(aka full boost), whatever volume the pulley is sized to deliver. Although due to the flow characteristics of an engine, boost readings may rise or fall as rpms increase. The Lightning is set for 8psi from the factory yet can yeild a few more psi up top with just air box mods. Apparently, with the Cobra boost readings drop off up top.
