which one would be better for stock twins. The 3 inch inlets or 2.5 because I have read about loosing boost with FMICs because of the pressure loss.

The NPR IC(Med): at 329cfm and 290°F on the inlet side of the IC, the
pressure
drop is 0.09psi. The outlet temp is 130°F, heat rejected is 55553
BTU/hr, and
the calculated heat exchange area is 1404 square inches.
Starion IC : (the bigger one) at 324cfm and 292°F on the inlet side of
the
IC, the pressure drop is 0.29psi. The outlet temp is 139°F, heat
rejected is
52287 BTU/hr, and the calculated heat exchange area is 1217 square
inches.
Saab 9000 IC: at 332cfm and 295°F on the inlet side of the IC, the
pressure
drop is 0.81psi. The outlet temp is 123°F, heat rejected is 60350
BTU/hr, and
the calculated heat exchange area is 1602 square inches.
Volvo IC: at 331cfm and 293°F on the inlet side of the IC, the pressure
drop
is 0.55psi. The outlet temp is 126°F, heat rejected is 58809 BTU/hr,
and the
calculated heat exchange area is 1539 square inches
for those of you who dot believe that this IC is good enough, check out some cars from Puerto Rico that run 7's 8's and 9's with this IC.

If those guys in PR are on the bottle, then most of the O2 ain't goin thru the IC.

Like I said: The large one probably won't fit. At least not in a true front mount application, in front of the radiator.
I'm pretty sure mine is the medium one. I believe the overall dimensions were like 9x28 or something?

the core alone is 15 tall X 23in wide.
the radiator must be stood up to fit it, but even with rad standing straight up, it clears the hood with NO problem. so YES the large WILL fit.
i actualy had on that was 19.25in tall X 19.25in wide i was going to use that DID fit. i opted to sell that one to someone else though. but not because it did not fit.
the one on the right is from an NRR.

HMMM... i beg to differ...i just went and measured mine. i know it was much bigger than 40oz's old one and fits in front of the rad. fine.

I just meant without relocating anything. Thats the best thing about the one I have, nothing has to be moved
Good info though

sorry about the newb question, but: what is npr, and why are the ic's so cheap?
How hard is it to get custom endtanks created? The ones in the pic posted by rxrotary looked very restrictive IMO
How do they compare to the m2/asp intercoolers or some of the better front mounts (apexi)?
