maybe this will have similar results for the RA..with just a k&n

That's nothing.. There's some other air filter you could get that will add 900WHP!!


/sarcasm

 

thats nothing? i think it's great for 50 bucks for just a drop in lol

 

I'm typically skeptical of claimed air filter gains. Because if it's not reducing restriction by increased filtration area, then it's reducing restriction by letting more crap through the filter - an idea I'm not too fond of. Just my .02

 

as far as i know , the RA dont have the X tune problem. So the RA is not running that rich. I'm sure you will see gain but because the tuning and hardware and design differences, the RA will not gain similar to the X with only drop in, in my opinion.

 

The Evo X had the bad tune, which with just a drop in, it gained substantial ( for a filter) gains. anyone know how rich we are running compared to the evo x? im sure it could free up a little more hp than your average drop in.

 

Actually, the R/A is running a bit rich. It seems to me like TTP Engineering is taking advantage of this with their plug-in "chip".

 

According to our data, there will be next to nothing as far as gains on a STOCK Ralliart with an air filter.

The Ralliart Air Fuel Ratio is much leaner than the Evo X due to its lower stock boost level and associated ECU mapping for those boost levels.

We have another ZChip Ralliart car coming in today for some more ZChip action. Stay Tuned.
