Awhile ago I read some article, it might have been on here, linked from here, or totally unrelated to here, where some triple turbocharger setup using ultra lightweight car type turbos with cutting edge fancy 1:1 impeller to turbine weight or something was supposedly putting down something like 1000hp on surprisingly moderate boost. I haven't really heard of it since then.
What i'm curious (both about that and related to that) is what is the biggest power attained without taking boost much beyond 60psi? The reason for this is from reading lots of articles here and elsewhere it seems that streetable O-rings should work up to about 60psi, over that you need not-streetable (short lifespan) fire rings to climb much higher, therefore I had set about 60psi and assumedly about 600hp as the max I should consider attainable on a two stage compound boost setup that I wanted to otherwise have long life. (when I wasn't shortening that with my foot in it)
Since i'm re-going over my build plans and such though recently i'm just reanalyzing my basic assumptions to make sure they are right. My basic priorities again are 1) long engine life (mostly keeping my foot out of it), 2) tow ability (I assume compounds for sure to keep EGT down, max tow HP of 400-500hp), 3) as much power as I can get for an occasionally wild drag time.
#3 could include nitrous, propane, CNG, super cool oversized intercoolers - just curious whats possible and feasible without the extreme pressures that it seems fire rings are required for which seemingly put a limit on boost pressure.
