Also that is a $500 core + $120 for a couple of end caps (save the 120 if you weld'em end caps up from aluminum scraps). That intercooler is sized for 900 cfm at 1 psi pressure drop and 50% efficiency, or 520 cfm, 0.4 psi drop at 70% efficient (at 20 mph airflow trough the ambient side) - how many HP are we looking for here? I figure 200 to 320 cfm is plenty, or am I way off? That's cfm of compressed air by the way. I'm currently looking to find room in my little Long EZ cowling for some intercooler that'll flow sorta 200 to 320 cfm at 70+% efficiency so bigger is better, except it gets to big and heavy. I'll have to re-read that NACA study: http://naca.larc.nasa.gov/reports/1944/naca-report-784/ I figured IF I buy a new core, $260 ought to be enough. like a 2-110 or 2-95 or 2-210 sizes but no flow graphs at : http://www.turboneticsinc.com/air.html their paper catalog has flow graphs. Where is the throttle body or a blow of valve? in that design? I guess right in front of the intercooler would be a handy place.
