That's the thing about the jug, you can run alot on high static compression engines like this with a much easier time of it, since you get massive charge cooling effect from the
N2O, which means you don't have to pull as much timing or resort to using low compression pistons. Wet kit, you can get away with alot more as the fuel side's covered but, I don't think I'd feel real good going over 125 with powdered metal rods. That's alot of cylinder pressure. 125 is going to to push like a 200+ HP gain blower kit, easy, due to no pumping losses and accessory drag. Plus, on a hot day at the track, you'll be laughing as the blower guys try to CO2/ice bag/fan their intercoolers and engine bays between runs, while you sit back and watch the action.
I LOVED the jug, best, easiest power adder out there, bar none. I hated filling the bottle and constantly having to monitor its pressure and temperature, though.
