WHAT IS THE BEST LS INTAKE UNDER BOOST? SINGLE PLANE vs DUAL PLANE BLOW-THROUGH DISTRIBUTION TEST!
I’ll always remember the primary time I used to be in a dyno cell whereas testing an engine with 8 oxygen sensors. As an alternative of simply having one or two, which is the norm on most of what we work on round right here, every cylinder had it’s personal O2 sensor, as a result of knowledge is sweet. Or is it? It definitely is frightening! However why? Properly that’s as a result of the O2 sensors you’re used to watching for information are in reality taking the combination from 4 cylinders and studying all of them on the identical time. That implies that one could possibly be lean whereas the opposite three are a bit of wealthy, and they’ll even out to the place the O2 sensor offers you a superb quantity you want. When you’ve got all 8 cylinders underneath statement independently, you see the great, the unhealthy and the ugly. And typically it actually is frightening.
Watch how this performs out in Richard’s consumption check. He’s testing blow by carbureted intakes on an LS to see how the distribution is between a twin aircraft and single aircraft consumption. Watch.
