It's good enough for draw through systems, yes, but how many slant six draw-thru systems have you seen being put together, lately? Or draw-thru V8 systems, for that matter, which was my point. They are just not very popular, though they don't seem to be down on power, when compared with blow-thru projects. I think it's the intercooler problem that keeps them out of the mainstream... could be wrong.
And, don't worry; if the alternative to the original creates problems, the users will find out about it soon enough... :banghead:
