Not quite....
Even though my ic core (726 cu/in.) is 124% larger than RS4 (323.75 cu/in.) pressure drop is still under the 2psi limit for the entire system. i just do it all in the core, where as the stock system as pluming losses and core losses. Also stock RS4 only has 130 sq/in. of cooling surface where as mine is 242 sq/in. Considering the number is MAJOR in calculating ic effectiveness, which do you think will make bigger numbers?
Every other car with this mod (skyline, Silvia, DSM) have nothing but good things to say.
Hot side fin count is the major factor in pressure drop not length.

You're the one who covered up their radiator, my design increases radiator airflow
You know what huge lag is because you have it, you told me so.
Yep, all those 11 second DSM, Supra, 300z, Silvia, and Skyline owners are wrong....
They all wish they had tiny coolers in front of their tires.

dual/dual flows more air accross the fmic and radiator
You say a LOT larger, like it's a bad thing?
Hot side fin count and type were choosen to optimize pressure drop along with the rounded and tapered endtanks. Dave and I disagree about how to make an S4 fmic, he likes big high volume pipes with square end tanks. My core is .5" thinner than his, but with greater swept cooling pass area (MAJOR number in the fmic efficency equation). I will post pressure data and temp delta's after datalogging, which he did not do.
