Hi all

the resonator box in the inner wing on the classic.

Is it worth removing.

Are there any pros and cons.

Cheers
Dave

seanie boy

have you got standard filter still if so then i wouldnt if you have a induction kit then i proberly would

silent running

No real reason to unless you need to put piping through for a front mount intercooler.

just makes the induction roar a bit louder and the recirc dump valve is a fair bit louder.

got mine removed and cant really see any increase in power.

Might take it of just for a bit more noise then.

i took mine off and you could actually hear the turbo spooling and dumping air off when you lift off the accelerater....

Removing the resonator will make more noise if that is your thing.
That mod on its own without any other alterations will also cost you a small amount of power eg 8-10 bhp at 335 bhp.

Harvey I assume that wil not be the case if you use the GP moto elbow to reconnect the standard air filter box back up to the standard air feed.

I removed the resonator on my 03WRX and was a bit concerned with people's comments that I would lose power due to the 'mod'.

To settle the arguement I RRd the car without the resonator and it came in with 312bhp, I refitted the resonator and produced a figure of 298.

I did make sure that the snorkel fed directly into the wing and that the airbox obtained cold air from the wing ie no air feed from the engine bay.

To be purely scientific, I should have taken the resonator back off and RRd again but at £50 a pop you can understand why I didn't

IIRC the difference in power did not start to become apparent until 4500rpm, until that point the graphs were identical.

This was performed on dynodynamics rr at Triton Motorsport.

LOL

somesays u loose power someone says it gains power lol

Sometimes the answers to the question make the decision harder.

might be a long shot but could it be that when being fed from the inner wing you lose the small gain in airflow from the small ram air effect of the air from the standard cold air feed from below the bonnet.
With the GP moto elbow reconnecting to the existing feed all you have done is remove the resonating chamber but not really changed the flow. Unless the resonator puts some sort of swirl in the air which makes the flow more efficient.

Dont think they do the GP moto elbow for a classic

scooby-k

biggest problem i can see with the classic is the air can be quite warm especially when radiater fan kicks in. subaru addressed the problem on the new age by feeding the air from the front of the car. but as Harvey has said the standard air box is good for 350 bhp.

More than that.

Would quite like to hear the dump valve dumpt, without having a new 1 on.

Dont want a fmic on, been there done that lol.

Just thought it was a good FREE mod for more noise and a little bit of oomph

Varboy

you can botch your own 'elbow' together from cutting up the resonator

better still you fabricate a cold air intake from the offside foglight area with a pipe leading directly to the inbox.

have a look on NASIOC and search for ghetto mod

and yes it is a good free mod
