Greddy Evo X FMIC
Isn't tube&fin lighter and cheaper to make while being less effective? So what's the deal of a "top notch" tuner company still using that "old" technology? Is there a reason to it? Anyone elaborate on the subject?
Tube and Fin
Pros:
Generally weighs about half as much as a bar and plate core of similar dimensions
Generally less expensive
Generally less flow restriction within the core than bar and plate designs
Less flow restriction through the exterior allowing better flow to the rear of the core and to a radiator, AC condenser, tranny or oil cooler, etc. which may be behind it
Bar and Plate
Pros:
Generally off greater heat rejection than tube and fin design
Those with turbulators offer even greater heat rejection
Offered in tons of varying shapes and sizes
Less likely to be damaged by rocks and debris
Charge air entry sits flush with core allowing for cleaner entry
This is old, but here is a little info on the differences.

The Greddy T&B has many good qualities that (I assume) can be efficient enough for higher HP cars. Maybe just not 700+.
Radius-ed end tanks, and the air diverter seem to address the flow issue. Like it was said above...only tuning will tell. I should be on the dyno in a week or so w/ the Greddy unit.
