I installed the intake in the 323 .. But when driving I feal like I lost some low end power, the the car picks up slower.....
The car picked up a lot faster before the intake .. hmmm has anyone also noticed this ...

anyone have any quims on why this might be .. Do I need to adjust the VAF ,,, do you guys have any pics of how to do this , I know I saw some on the net , but I can't remeber where, I have to check Mazdaspeedwests site again and see if it was on there...

I also cleaned out the throttle body also ... sprayed it out and gave the flip door a good cleaning lol ...
The car runs sweet though , just need to fix the muffler now ...

I will have pics tonight

Did you replace the VAF as well? If not, then there's no need to adjust it.

Bruce95fmla

no I did not replace the VAF , ok so i don't need to adjust it ... thanks

I will reset the ECU tomorrow ...

thanks

what kind of intake? I'm gonna guess that if you made it yourself, and you used a 3" pipe....that will hurt some low end.

and for future reference, my site www.mazdaracer.com

Bruce95fmla

no , I did not use a 3" pip ... lol ...
factory tubing is on there ..
It just feals like it has lost some low end grunt .. hmmm

When I put a cone filter on my Pro I noticed a slight loss of low end power as well. Didn't notice it at first, but after a few days of driving, I started feeling it more and more. Loss of low end, but definately an improvement in mid to high end power. I guess if you weigh them out there's not that much of a difference at the end. I did eventually make an improvised CAI, so I am overall pretty happy with how much air gets into the engine.

Have you considered an RX-7 VAF as well?

hey bruce, from my knowledge of what people have told me from discussions in the past, cone filters decrease torque but increases a little hp. so that might explain your little low end problem when u start driving (from a stop?). someone correct me if im wrong

kinda bad for an automatic

The stock air box is restrictive for mid-top end power but offers good low end grunt (more so than a cone filter) In order to get that low end back, either fanagel a CAI into the stock airbox or start going to town (header, exhaust, etc, etc, etc....)

your the best,,,
I am gonna do that when I swap the 1.8 in ....
most likely after the 1.8 is in the protege

hmmm 2 turbo cars ....... an idea to contemplate..
