Take a 1000 hp to spin? kobelco 14-71 std helix with minor dmpe mods. At 20 over it should be moving 1500 hp worth of air and making 40 psi of boost. it makes the right boost number according to my data. If I put 1500 hp worth of fuel to it, it makes 750 hp and just barely colors the plugs (assume 2 lb/hr/hp and 4.1 target. Ya I know, that’s a lean target but at 3.5 it makes even less power) if i put 1200 hp worth of fuel to it, it makes 850 hp and burns all the plugs to the top thread. If I put 1000 hp worth of fuel to it it will make 1000 hp for about 1 second before it torches the heads completely off. The blower case never gets hot on a run, but I don’t measure iat yet. is it possible for a blower to be bad enough to soak up 600 hp more than a normal blower or almost 1000 hp total???? I’ve changed converters twice and rear gears once but the power just isn’t there. Different heads, cam. 50% through the blower up to 80% through the blower. I can make the plugs look exactly how I want on every cylinder with no problem. Only oddity is the right side idles WAAY lean even if I flood it with the barrel valve. Actually only 2,4, and 6. 7 and 8 are so far at idle they’re hard to keep lit.
