How much power can the Vortech Aftercooler handle?

Just as the title says.

I know LJ has gone 139 mph with it. I've made 680 rwhp (auto) with it, which is about 850 fwhp and good for ~142 mph.

I'm just wondering if it's holding me back.

Anybody??? TTT

id call em and see what they say

If possible, I'd measure the boost levels immediately before, and immediately after the Aftercooler. That would be a dead giveaway that the unit is a restriction or not...
