Can you say 100 psi

Google Blowermax too hasnt dynoed it yet but estimating around 2k hp

Steve, its worth noting that he isn't actually runnuing that much boost. Guys are running over 50psi through the 4G63T blocks. What Spyro's idea is is to run more compresion than most. THis amkes the engine more efficent (as long as you dont get dept.) at any given boost level and thus make more power. Think they where looking to run around 2-3bar on the 2000bhp methanol monster.

Thats fine when you have 6.6ltrs, but this guy is doing it with 2.0! also with the duramax you have 32valves, again this guy only have 16. This makes a difference when it comes to shifting air and thus making power!

I met a guy at a drag auction a few years back that does similar stuff here in WI. He was buynig like everything at the auction so we went up and talked to him and dubbed him "moneybags"....lol. Real cool guy and quite the operation hes got.

We went up and toured his shop....Wow.. he had machined a complete engine out of a block of aluminum. Does some R & D for nascar in his secret room....lol. wouldnt let us in there. and he designs a lot of cams for comp cams he said.
I dont know if he lays low but we'd never heard of him prior.

with 6.6 the volume of air is over 3 times what he is moving thats like blowing up a small balloon and blowing up a large balloon its not going to take much to blow up the small one and you will get higher pressure with less because of Lohm Laws for Gas pressure is resistance to flow so with 16 valves 2.0 thats a huge choke point and will you will get alot of pressure with less but then with 32 valves and 6.6 liters of displacement its going to take ten times more work to get the same achieved pressure as that 2.0

I'm a pneudraulics mechanic in the airforce and on our helicopters the pilots would complain that at ground idle system 1 pressure was at 3000 psi but if they used the controls it would drop a lot and I always had to explain that they were not getting their full flow until they were at 100% rotor speed and full flow of 7.5 GPM

Totaly see where your coming from, however i was refering more to the BHP the setup was making, rather then the PSI needed.
