Need intercooler sizing help.

Yes, charge air path cross section is the same. For almost identical charge air cross sectional area, the Bell cores are rated much more conservatively than Spearco's.

I talked with Gerhard Schruf at Bell Intercoolers today (co-owner/engineer with Corky Bell) and got everything figured out in 5 minutes. I'm finalizing my end tank & tubing designs this weekend and ordering next week. Bell says they can build my design and ship in 3-5 days. Yay!

I'm going with a 28" x 3" core (charge air cross section) in either 8" or 10" high. Gerhard said even 6" core height would be plenty given my reasonable discharge air temps but more height will aid in efficiency especially on those 100-110F summer days and the additional height gives up almost nothing in terms of pumping losses through the core.

Now all I need to do is take a sawzall to my radiator support between the headlights, lose my center hood latch, and rebuild from there.
