They did some testing comparing the different intakes (Stock + K&N drop in, PRL High Volume Intake Street MAF, Eventuri Intake). The question that I wanted to answer was... Is the Eventuri worth 5x the money? (PRL = ~ $500, Eventuri = ~ $2000).
As expected, the intake doesn't do much to peak power gains (PRL = ~5WHP/?WTQ, Eventuri = ~ Peak 8WHP/Low end at peak boost 12WTQ). But that's not the whole story. From what it looks like so far, it looks like the Eventuri is better optimized - tad bit more torque and faster spool. Alex said he was having some trouble tuning with the PRL. I wonder if it's because I have a dirty wildfire soaked filter lol.
E25 - E30 Tune w/ Eventuri Intake & Catback vs Stock Tune w/ Catback
E25 - E30 Tune w/ PRL Intake vs Eventuri Intake. Both w/ Catback. Corrected to dynojet.
Edit: Added dyno graphs. It still doesn't make sense to me and it's not a true representation of the intakes as there's some ethanol in it. Currently waiting on the uncorrected Eventuri vs PRL comparison.
