Say you add a Buschur WAI to a car that has an SAFC which was dyno tuned to 11.8-12:1 air fuel. Also say you keep the stock mass air pipe and do not upgrade that at the time, only the filter. Will the A:F lean out enough for the car to need retuning to be safe? Help?

 

You know you want one.

 

Hush up, you! I've already ordered one lol turn around in the brain.


I do not, however, want to run too lean before I can get the car on the dyno with the filter.

 

Excellent.



I am not sure how much this F's with the a/f but since you have already tuned out some of the factory richness I would be careful of course. Maybe bump up the fuel a bit just to be safe at higher rpms. ??

 

Better safe then sorry 0 out until you can get back to the dyno. Because there will be some Maf readings going up and down with the intake.

It won't affect you that much. You will probably be fine but if you want to feel good about it , go down about 1%. 12:1 is a little bit on the lean side I thought. Just a sugestion. I am sure your consern will mostly be right on and around your highest torque range. Rather safe than sorry.

 

Wai?

Noize,

Aren't you the one telling us not to remove the stock airbox
cover??
How's getting a WAI any different..

 

That absolutely was me. I bowed out of that part of the thread, because a lot of people were more interested in sound than learning about making power with the intake.

I still think removing the lid on the stock airbox is completely ghetto. Using the stock paper element, you're not going to let any more air in there, and at that point, it is hotter air restricted to the same design. Moreso, any water that gets into that highly absorbant stock paper element has nowhere to go but follow gravity- straight down and out the bottom of that filter- right into your air tract. No thanks!

Regarding the WAI, I'm going with a couple guys to rent out a dyno for a day later in the year. I'll be testing this unit and the stocker back to back with open and closed hood runs. I'll also attempt to fabricate heat shielding for the WAI element if its cold underhood air-temp power looks more promising than the stock unit.

With 100% honesty, I don't think it will make power; I hope I prove myself wrong! But I wanted to make sure I didn't get too lean in the interim between WAI installation and dyno tuning time.

 

warm air intake

 

After that thread... I actually bought a thermometer...

It hasn't come in yet.. but once it does... I like to know the
termperature difference when cruising at speeds...

 

Awesome! Please post results for both the box and the WAI.

 

Noize, the post-5500rpm power gains are there with a WAI, seriously. I am looking forward to your dynos... is it a hub or drum dyno?

 

drum this time
But it was the most runs I could get for the cheapest. Looking like early December to get it for the whole day.. Stay tuned! I will be the "slow" 4G63 car on the dyno that day, I'm sure, as the other car is a 1G with a FP green and another 1G with untold mods.

 

WAI? I would have thought you were talking about Water/Alcohol Injection with your concern about leaning out the car to much.

Noize, warm air intake? wtf good would that do?
