Has anyone deleted the resonator in the stock airbox? or made a larger snorkel?

I drive like that daily

After the tune I honestly can't keep my foot out of it... it's just to fun ahahaha

I've just measured the stock snorkel intake and it's 60mm at the opening give or take, which is plenty. IMO you want as little to disrupt the airflow as possible so I have blanked off the resonator holes inside the snorkel and capped them at the bottom to reduce any possible heat soak.

I have also capped off the 50mm hole in the airbox and cut a 46mm cardboard blanking plug for the inside of the airbox and used tape to airtight the hole like so:



This means that there is noting to disrupt any airflow from entering the snorkel all the way past the filter. I'm still awaiting a silicone bung to remove the resonator in the intake pipe.

FWIW, I've got airflow results for my setup with the snorkel. I can test some without the snorkel on if some would like to see whether it makes much of a difference? That will stop all the assumptions about how well the snorkel actually does!

Sorry. I read the 46mm as being the ID of the snorkel inlet.
60mm is much better but still 15% smaller in area than the 65mm throttle body. So a 15% restriction to the potential of the throttle body.

Right, I've got some definitive numbers for you. Some interesting figures though. My setup is a K&N filter & AVO pipe for reference.

Full intake system, ambient temperature 4*C:

Max MAF - 144.0g/s
IATs - 4-15*C

Snorkel removed, ambient 8*C:

Max MAF - 140.27g/s
IATs - 22-34*C

I actually saw temps of up to 44*C on the IAT pre-logs when connected via ECUTek. Sounded great but the car could not handle the high IATs and started bogging really badly!

One conclusion, removing the snorkel has made no difference except made the intake incredibly prone to heat soak. I'll run some further tests once I return the snorkel with all resonators removed.

Did you get data logs with the stock intake system to see if there was any change in a/f ratio after the intake install. It's my understanding the car stock runs rich which most factory cars do anyway.

keeps us posted for the last data with resonators removed. Great info!

What about with all resonators deleted? Not necessarily the snorkel deleted. Thats what im interested in! But this is very cool!!!

this is my car, a true cold air home made intake. it extends off the stock snorkel and i felt a bigger gain with that, then with a drop in. this is a honda thing though lol

Any other pics of this setup? I imagine it would be a really cost-effective CAI

I refitted everything yesterday. I might get a run out in the car later or tomorrow morning so I'll get some more data for ya.

With OBD readers (ECUtek, Torque, Rev etc) people can start getting data rather than speculating and actually test things. Following my results yesterday I'm going to test how bad the heat soak on an injen is on a mate's car.

Grip Ronin, do you have access to any of the above and what's the rest of your intake setup?

i dont have anymore pics. its just 2 elbows and a pipe.

hyrdo lock is a fear but id have to submerge the entire intake opening underwater for that. id just open the air box in the engine bay before that lol. ive had this setup for months no problems yet

the rest of my setup is stock. with no dyno runs
