N52 intake shootout

[hoveringuy]

I finally got the DISA-enabled ECU and had a chance for a quick test drive. What a hoot!

Next step is to put a few miles on it and take it to the dyno...

I know you went booster delete, so for those with booster'd setups, time will tell what sort of combo will work with that.

Spoiler alert, before I bolted everything I test-fit a Tesla booster. Clears fine.
Note: All the cool kids are running the CR-V remote reservoir (there's a picture of an S54 car with that setup somewhere....) that gives even more room.

There is some data on this already, N54 intake mod was widely discussed starting around 2016 and there are some before/after dyno plots that show an increase in top-end power, but most of the threads devolve into name-calling and nothing really shows real-world performance. My theory is that I spend more time accelerating between corners in the the 4k rpm range than drag-racing down the straight at 7500, so lap times would really be the ultimate barometer, plus not everyone cares about power at 7000 but just wants useable power for commuting.

I think that's a valid theory and thought process.

More power down low to keep up with a Chrysler Pacifica and overtake a Toyota Sienna with more ease would be nice. I know you went booster delete, so for those with booster'd setups, time will tell what sort of combo will work with that.

EDIT: OH MY LAWD WE HAVE A SECTION BOYS, ITS A CHRISTMAS MIRACLE.

This aligns with my interests, looking forward to all your findings.

Yay! I love hoveringuy experiments

Excited to find out the pros and cons of each manifold.

Looking forward to updates!

I have, at this point, gotten my N52 swap pretty well sorted, run plenty of track days and put enough miles on it. This has been on the N54 intake, which isn't necessarily the "best" intake for the motor, it just happens to fit, clears everything and makes good power.

My mission for this year is to run 100% on the dual-DISA intake and do a comprehensive compare-and-contrast. Dynos. Lap times. (top speed on the straight, too!) Driving impressions, etc.

I have the new intake completely mounted and have already driven it a bit. It still has the tune from the N54 intake, my plan is to have a duplicate ECU just for this intake. It definitely has more torque down low but can't say too much more because the DISA isn't active yet. The sharp-eyed will notice that I have a dual-MC booster delete to clear the intake,

(this space reserved for future updates, like who would take it?)
