I'm looking to increase my supercharger whine, and in my search the bwoody intake always comes up. However, there doesn't seem to be a consensus on if it actually reduces overall hp/performance (due to heated engine air being sucked in), or if it improves it.
I just want to increase the whine sound, but not at the expense of power, even if slightly. Has anyone done any before/after dynos of this intake?
So far, some dynos have shown gains (
Bwoody IAT harness HP gains!!! Dyno results) and some 1/4mi track results showed gains of 0.1-0.2s and an increase of 1-2 mph trap speeds that have been debated.
With no filter and the stock box, about 0.1s gain in the 1/4mi (
No stock filter and OEM airbox)
No reports of losing HP with them.
If the intake temperature on the BWoody exceeded the stock air box temperature (most likely to occur at idle), you would see some loss in initial performance.
In two measured scenarios on previous Challengers, an open filter element took roughly 1 minute to reach a certain temperature whereas the stock box took 3 minutes. Conversely, once moving, it took 1 minute to reach 5 degrees above ambient temperatures with an open element vs. stock box it took 2-3 minutes to reach 5-10 degrees above ambient. Not saying this is the case for the Hellcat since the design of the stock airbox also includes the front air catch inlet. However, you'd likely see similar results where an open filter will react quicker than the stock box to intake air temperatures changes.
Overall, an open filter element will react quicker to temperature fluctuations than a closed filter air box (you'll notice this in throttle response). Just don't sit idle too long and keep it away from rain and you'll be alright.
