Re: Dennis Moore's thoughts on heads
I'm only running a throttle body with 2 openings, not 4. The longer runner design is supposed to increase low torque, like the mid 80's TPI systems chevy used on their Vettes. I don't know, it seems to have decreased my plane time, but I did install smart tabs at the same time. The boat litterally ju8mps out of the water with a mercruiser 14X21 SS prop.
The lower CC combustion chamber, 17occ runner design of the new heads should increase compression, and give more high rpm (low to mid 5000 rpms) hp #'s..., shouldn't it?
The new heads should be here today, and I'll report back. In the meantime, I was fishing off Longport/Atlantic City, (caught approx 30 blues)NJ and got boarded by the USCG yesterday. . I got a warning for the expired flares, but they didn't care about my MPFI system. They really were just happy to see my life jackets, and spark arrestor. Guess my system does pass the USCG inspection as I got a slip that says I meet all federal regs...
