That's what I was trying to say about the Lightning intercooler...

Pics can be seen in the articles on this page: http://www.timskelton.com/lightning/articles/index.htm

 

The Lightning motor does not have all that pushrod stuff and cam in the way, so the intercooler can be quite deep.

 

Yeah, I was just trying to say that 'making the' / 'installing a' intercooler the full length of the base of the blower would 'probably' be beneficial since the L's come like that. (not knowing the F-body Radix's do too).

 

It is not the length, it is the "depth" of the intercooler in this case. Putting a longer I/C core that is not as thick will not result in any gains.

 

How close are the blowers to the bottom of the hood? Would there be any room for a deeper IC, with some kind of blower spacer?

 

just buy a whipple J/K

 

Even if it has more surface area??

 

Yes..

 

Fandango's idea crossed my mind too. Put a spacer between the Radix and the lower manifold. Then mount a deeper cooler that extends up into the spacer.

 

Surface area does set the measure for cooling calculations (other than design bar and plate vs. fins etc.) But if you look at the roots blower, it outlets in a small section just below the blower. The LS1 kit has 1/3 of the intercooler acting as a 'heat sink' instead of a medium of convection cooling.

Lengthening the intercooler would have some benefit if the intake manifold plenum volume was increased by way of larger height. Although, at higher pressures, air finds the quickest way out - directly below the outlet in this case. What you really need to do is gather all of the heated air into a pipe, send that pipe to the intercooler, into another pipe to take all the cooled air back to the engine. ...tough to do in this case.

Guys have run what, 12psi on these blowers? You should be okay. And that is a lot of power gain. You are just too much of a gear head BigTex
