366 + 122hh(3.4)= 12psi, 325 +122hh(3.4)= ??psi
here is the 366 specs.
with the 5.3 what kind of PSI am i looking at with a 3.4 pulley?
complete LS2 engine. Motor was built for a corvette to hold 20psi from forced induction.
Complete 366 Stroker includes, 3.622" stroke, 4340 callies crank, eagle 6.125 3D rods, Cartek/Diamond forged pistons, Balance assemble, Z06 oil pump, Nitrated double roller timing chain, custom cam shaft, High grade cam bolts, Plasma Molly ring set, Clevite H series race bearings, Cromoly push rods, Cartek Stage 3 ported heads, New valves, Titanium retainers, Race springs, Viton valve seals, Serdi "radiused" valve job, CBN milled .005, new head bolts, Hone with torque plate, all machine work, clean, blueprint, and assembly.
I have upgraded the cam to a Lingenfelter GT2-3 cam which makes it idle better than stock, but gives it excellent power with boost. I had a paxton novi 1200 supercharger first, but then upgraded to the magnuson mp122 with 12 psi. Because the escalade was AWD, nobody could dyno the truck, but RPM in Garner, NC who did the tune estimated the HP to just over 500hp at the engine. The engine is capable of well over 800hp which enough for most folks.

PSI is resticted air flow right. the 366 has better heads and a cam that will allow more air in and out quicker. there for reducing the restriction(psi). right/wrong??

i asked the original owner how much PSI it made and what pulley he had. he said 12PSI and the pulley that came with the kit. well there is a 3.4 on it right now. that is where i got 12psi on a 3.4".
