How many pounds of boost will the stock intercooler take without being over restrictive?? I just ordered a couple new twins (Switzer S4-D on top, S4-T on bottom) and need to know.. They said my combo should move some pretty serious air.. All help is appreciated...

most with twins have pushed ±60psi without changing the charge air cooler... there also isn't really a lot of aftermarket coolers avalable... i think piers has some, but i am not sure...
