My first concern is AFR. It will be quite some time before I can afford a Hondata s300 and have my FA5 dyno tuned. With that being said I would like my AFR to remain near stock with a short ram intake.

Now Injen claims a near unaffected AFR according to their dyno charts, but the Fujita seems to gain a tiny lil' bit more power and torque based on their charts. At the same time Fujita doesn't say anything about the effect on the AFR.

As it stands now I would like to purchase the Fujita short ram, but whats it gonna do to my AFR?

 

While I can't say exactly how the Fujita intake affects Air/Fuel ratio....I CAN say that it keeps it within factory limits otherwise the car would throw a CEL. I've had my Fujita for well over a year now and have never thrown a CEL for a lean or rich mixture.

Just remember to disconnect the battery prior to install. And let the car idle for about 10-15 minutes after installing the intake and re-connecting the battery.

 

forget the s300, get a flashpro from hondata instead.

 

S300 wont work anyway.

 

another and better reason to get teh flashpro then

 

s300?
hmm i didnt know the new si came with a b series

 

Hmm lol I didn't either, sorry I hadn't even looked into ecu's yet, just assumed. Its weird I'm so used to B-series, I'm starting to get used to the idea of owning a K engine.

Thanks RICO,

While Im at it ima thread jack my own thread!!! Two things,

1) Opinions on this Skunk2 "mega power" header, so far its what I have decided to purchase.
2) Opinions on Apex'i WS2 catback exhasut, I found a few crappy youtube videos so is it relatively quite with normal driving and a nice tone in vtec? Its looks somewhat cop proof to...

 

WS2 is keeps the noise down in normal driving and has a nice deep pitch in vtec. the header is a good choice.

 

well maybe u should.. the flashpro is only 695 and you dont have to pull your ecu..

 

maybe AFR isnt an issue with the Fujita. But what about heat soak? That is the one thing i couldn't help but think about when i installed my Fujita.

I don't like how the upper radiator hose comes in contact with the intake. Or how far back in the bay the filter set. Anyone have a way to correct this? Samco or Gates radiator hoses maybe?

 

heatsoak! that's why i always just retain the stock intake personally, since teh rubber tubing from factory protects better then a aluminum aftermarket pipe, and in the case of the k20, keeping the intake temps down is important, the way honda ran the hose's was sorta a temp killer, lol.
