It seems that a functioning VTCS provides better air swirls, and thus better fuel atomization...Also it helps with low-end power....if you remove VTCS, you loose a bit of low-end, but gain power in the upper RPM range. Logic dictates that Mazda would not spend so much money on research, just to put those flappers to block airflow.
Don’t believe I said they put them there to block air flow. I know why they are there. I’m currently built bottom end with a big turbo I don’t care to much for low end power as most racing is going to happen at 3k RPM’s and up.
@@AdamAkers okay great I was wondering on the correct way to do it, has yours been holding up? I went with the high temp jb weld… I thought that would be the best option
I didn’t fill the hole for the map sensor the map sensor is on the left side at the bottom I filled the holes for the VTCS system because I deleted it. Also I ground off the supports because I don’t need them any more.
@@AdamAkers thanks for the quick response! Yes - turns out I was mistaken about the MAP sensor location I buzzed off all of the VTCS supports this afternoon
Yes! You need to have a custom tune otherwise your car will run awful. Also it’s going to run rough in the winter. I wouldn’t recommend doing this unless you’re big turbo.
Disconnecting it opens the flaps all the way but they’re still in the way I also ported out my runners making them bigger so I had to completely remove them.
I know this is an old post but bro, you did an excellent job!

Is flaps open or closed when vacuum valve don't work? P2009 fault

Nice job.
I had a PnP intake I’ll be honest I didn’t feel anything I’m considering trying out the st manifold
Did you use anything for the jb weld for support or did you just put it on there? I’m about to do the same just wondering
Thanks
Yup just filled the holes with it taped the inside so no access enters the manifold.

Why did you grind off the supports and fill the hole for the MAP sensor? Isn't that still needed?

They come stock with the insulator

The weed whacker! 😂😂😂😂
My speed6 has that pad
Any benifits from this for stock ko4 with a full bolt on and tune?
They’re there but small. Even big turbo the benefits from this are small I’ll upgrade to a JMF intake soon.
If I have it tuned do I have to re tune it to do this ?
Yes.
Do i need accessport to avoid problems when doing this?
Yes! You need to have a custom tune otherwise your car will run awful. Also it’s going to run rough in the winter. I wouldn’t recommend doing this unless you’re big turbo.
Instead of deleting it completely, why not just disconnect the solenoid? Same thing no?
Disconnecting it opens the flaps all the way but they’re still in the way I also ported out my runners making them bigger so I had to completely remove them.
@@AdamAkers im lazy to remove it lol im just gonna disconnect for now and delete the codes
For the VTCS delete do I need to be tuned?
Yes absolutely. You will throw a code and it will not run correct.
@@AdamAkers what code will it throw ?
😬 GOLD THOUGH? I thought you were trying to make it look better 😆 to each is own I suppose 😝
Does vtcs delete need a tune?
Yes you will require a tune with this, because the ECU will think it’s getting too much air and set off a code.
