Intercooler sizing assumptions
I just got my spearco guide to intercooler and was wondering if any of you guys have some input. The flow charts are based off of engine size. So my question is, should I go with 1.3L. Considering we have combustion on one rotor 75% of one rotation (rotor), I think we should assume a larger engine. Let me know what you guys think

Well I know little in this subject area, but clearly a rotary doesn't breath like a 1.3L piston engine does. I would suggest you find some engines with comparable power/breathing characteristics. We don't want this turning into another 'is a rotary a 1.3L or 2.6L.'

The cfm will be more accurate, especially if you want to compare the intercooler stats at different rpm's. If you don't want to figure out the cfm on your own, then 350cfm will be close to your max figure.
BTW, the 13B is most comparable to the 2.6L / 160 CID.

Ok, so those CFM #'s listed are NA cfm's and not boosted CFM? I'm shooting for about 400 rwhp out of a 60-1 or something similar....ahhhh..so many assumptions. Core 2-192 looks pretty good, as do quite a few others. Pretty much any of the cores that they list for $518.00 looks good..DOH.
I also need to figure out where to route the IC pipes. Right now it's looking like making a hole where the old battery vent pipe was and another where the fuel pump relay lives. It seems to use the Greddy kit, you have to ditch the windshield washer tank. My IC will be limited to the space between the *frame* rails in the area right where the horns are located, just infront of the oil cooler.
so my core with endtanks and outlets (top view) would look kinda like this

You could do it like this... top view. Using mandrel bent pipe it shouldnt choke the air much. Or you could have the end tanks welded differently.
These guys have an excellent lay out of the different styles you can do
