The numbers your looking for are nothing more then arbitrary information. Guys love numbers...period. If I tell you it will handle 800hp...you'll be happy. If I tell you 650...you'll still want a different unit. I don't believe guys keep records of what the intercooler are responsible for. It depends on which part of the country you live in, how humid, elevation, and the entire engine combo. I can tell you this...my friend has run 10.90's with a stock intercooler with a Dutt neck welded onto it. Don't get caught up in the numbers. You can give 5 guys the exact same parts, and they will never tune any 2 of them to be consistant within a few tenths. Those 5 guys will be within 2 secs of each other. happens here all the time.
With a good proven combo, a really good tune, and a chassis that works...I'd bet low 10's with that cooler on the right day with the GN1.
The design of the PTE was simple...we have this many square inches of space. We have mounting points in these locations. Cram as much intercooler into those 2 factors as you possibly can. It is huge, but it's also selling for $1000 now. You can buy the RJC Megacooler for that price. When it was $750...it was a great deal.
