Paxton a/a ic

Well i ordered a custom IC thats way more than i need (rated at 1200hp) at the begining of summer but it still hasn't came. So i'm thinking about ordering a Paxton a/a ic, but was wondering what is the max HP on those, I have a Vortech YSI-Trim and plan to run 20 psi and hoping for over 700 HP. My friend thinks the Paxton IC isn't that good and should wait for my custom one, but i was wondering if anyones had experience or heard anything about it on high hp cars running boost around 20psi, or should I keep waiting for my custom one?

I know but its been so long and I keep calling but it still hasn't came, so i was just planning on canceling the payment cause i used my credit card and get the paxton one cause i know that one will come in in about a week.
