Mate, you’ve done a great job with this video. If I where to point out the only issue, it’d be that it wasn’t the PCV you removed. It was the crankcase breather. The PCV valve is the white plug in the rear left corner of the cam cover. Only a tiny inconsistency. Otherwise, you’ve done bloody well.

@ysomadbeats4 жыл бұрын
The Restricter in the air box is to increase the velocity of the air going into it for more low end power. It’s not much of a restriction at all, it’s just forcing air into a narrower hole to get it through the filter quicker
@backyardbunkybuilds74614 жыл бұрын
Hi Harrison. Yes that is correct but at higher rpm it becomes a restriction and we are regularly seeing 6000rpm
@jarrod64004 жыл бұрын
Yeah, old mates not wrong here, when your engine revving out its wanting to be breathing in more air so a restrictor in the airbox seems silly if you ask me. The barra has enough low end torque already there Haha.
@ysomadbeats4 жыл бұрын
Jarrod the same about of air will go into the the engine reguardless, the only difference will be its velocity, the restriction adds pressure to the air which forces it though the intake quicker. You can test this with a hose at home. Fill up a bucket with the hose and time how long it takes, then do the same thing but pinch the end of the hose, the 2nd bucket will fill up quicker because the faster you push out water, the faster the water can move to rush behind it. Same principle applies to engines and removing that restriction decreases the amount of airflow across all rpm, it is however much more noticeable in the low end then it is in the high end, if he’s not opting for a larger intake then he should keep the restriction there.

If you just disconnect the breather pipe from the cam cover outlet to the air intake system and put that little air filter on it it will throw up a check engine light. You either have to run an oil catch can or run the breather hose into the silicone pipe intake otherwise it will keep throwing up the check engine light.

@@backyardbunkybuilds7461 I think you will find that there is no low RPM power loss from changing your intake pipe. But also no low down benefit since the standard air box flows enough to not cause any significant loss up to around 4-5000RPM. After that as you have described you will get a power increase. People believe some strange stuff that they don't even understand. All the power due to velocity effects is for intake port size and extractor diameter including length, not with an intake pipe. Reduce restriction before the throttle body and you will not see any negative effect!

Yes that will work and probably perform just as well. The stock intake pipe has a muffling system to reduce intake noise but it shouldn't restrict flow. So you should get the increase in flow without the noise. 👍🏻
