I only got a 'B' in thermodynamics, so someone who did better will have to explain to me why airflow through a serpentine path is more efficient than a straight path . Looking at the intake and exhaust systems, it sure seems to me like there's lots of hp just waiting to come out. The aftermarket will go after this if it makes economic sense. Hopefully they'll also get rid of that annoying exhaust boom at 2100 rpm.
The Bellteck affect: This is what happens when Bellteck has too may beers and BBQ Beans. The internal pressures cause a system malfunction usually resulting in a mixture of deadly gases easily released with a minor reconfiguration or roll to the side.Kodiak said:It’s called the helmhotlz affect. This creates a wave of pressure that stuffs more air into the intake manifold when the switch valve opens. This is a relative simply way to boost power. Alternating the intake system would be a significant mistake. It is doubtful you will duplicate the tuning that has been accomplished with several Cray computer modeling systems.
I added a Borla catback to my Expedition. It did change the sound to a soft rumble but ya hardly would notice unless you're listening for it. It certainly did not provide any noticable increase in power or mpg. It's supposed to reduce the exhaust back pressure to help in this regard but knows how Honda's computers are going to react to that. I won't be doing it again, not worth the cost.maybearidge said:I sent a message to Borla asking when a Ridgeline Exhaust would be available. Did you get a nice sound (v-8 like) or one of those annoying rice burner sounds?
yes, but within certain parameters. Weather considerations, sound level, over all power, etc are something that aftermarket intake and exhaust makers don't have to worry about.shovelhd said:The Cray is a very outdated computer
Seriously, do you really think that Honda optimized the intake and exhaust system for maximum power?
