16 psi CAN net you nearly 450 rwhp with a 60-1... allegedly. I haven't seen it done yet, but its possible. The most I have ever seen was BDC and his FC doing 425 rwhp at 16psi with his 60-1 hifi with a relatively small, undivided .96 exhaust housing. bigger exhaust housing and more fuel... I think BDC's car could top that 450 mark...

Brian, hope you don't mind, but I'm going to post your dyno because its the ****:

 

you can run 50psi on 2mm seals. its not the seals that limit the boost, its the fuel and tuning. the 2mms actually work better than the 3mms, the 3mms just offer more resistance to detonation, giving you a lil more leeway in tuning the car.

 

kurgan is right tuning is VERY important, i guess it is so common over here to have 400-500 hp 7's driving around everyday i forgot to mention that. i wouldn't go as far as saying running 50 psi of boost on 2mm seals, tuned properly i would say no more than 30 psi, but 2mm seals are the best!! 3mm is more for a tuning crutch and extreme boost!

 

i was making a generalization, not a definative statement that its safe to go out and run 50psi on your stock seals..............but by all means, id kinda like to see what detonation will do @ 50psi, just not on MY internals
