i think u should send be a set for testing purposes, i'll get a before and after dyno, installed on the dyno

 

no maf's or he converted to MAP????? wheres the maf? if by the filter isnt there to much turbulence, doenst it affect the MAF? looks good though!!!

 

this was in my newb stages and before i knew they sucked

anyone wanna buy em?! LOL

 

I completely understand that. My main concern is just that I have heard so much about the great job done by nissan engineering these that I have heard there isn't much room for improvement! If anyone can improve upon them, I hope they do! I also wish the OP well in this project! I meant nothing negative by my post and hope nothing negative was taken.

 

i dont yet know if im a believer of this CAI setup because so many intakes have failed but i will support it with one point.

nissan engineering was amazing when they created the intakes for our cars. NOW, there may be no room for improvement with a short ram intake, BUT, nissan would not develop a CAI for the liability of water gettign up into the intake. i have never seen a factory car come with CAI. just my 2 cents.

 

Heh, that's cool.. This is generally for my car. I am pretty impressed with the results since I was expecting nothing myself. At stock powers levels I will it is probably agreeable that the factory intake system is more than enough. Although I do have camshafts that I am planning on installing as well.

I am figuring power from filter elements we used and possibly reduced inlet temps. The AFR's are very similar except for the on the top end where it clearly lost horsepower. The car actually ran richer here. Part of me is curious to see if we can play with the AFR on the top end to see what we can possibly pick up. I have another set of K&N filters I will be trying next week that should help me out a bit. Although it is agreed the stock boxes would get the best fresh air but that still doesn't account for the clear gains I did see. More testing.. more fun... my

Nope! If I had to take the bumper off.. I wouldn't have done the intake down there at all! I'm lazy!

Both... posted plots are with the filter.

Probably not...

1 million food stamps I don't think I am going to go into production with them. Just a 1 off set or 2 color matched to vehicle

Yep... went rich on the top end.

uhhh Thanks ... Skeptism is permitted... If it makes you feel better .. ME Too!

Nah, intakes have been worth a very small amount of power from jump. That doesn't stop people from doing them. Call it the inner ricer in me. Since when did they become the jury?

Underneath, it looks so much cleaner that way. I am sooooo picky about small stuff.

 

If the power gains are real and not just dyno variation (etc.) then I would put it on a couple hp to filter elements, and a couple hp to the smooth tube all the way to the TB. Less turbulence into the manifold should be good for something.

 

updates???

 

what about heat soak, are the piping metal, if so that will attract a lot of heat and may lose power.

 

Myth.

 

We need mythbusters!

 

ATTRACT a lot of heat is definitely the wrong way to describe/explain that. aluminum and steel are very good heat insulators (this is why when you lean against a piece of metal in your house it feels cold, it pulls heat from your body very quickly). there are coatings you can spray it with to aid in the repulsion of heat.

HOWEVER, once the engine is warmed up - the surrounding ambient air is a continuous ~ 215 - 225 F (correct me on the temps). so either way, a plastic or aluminum tubing will heat up to about that temperature. plus, the air moves through that space so quickly that the temperature gain isn't really what your concern is.

the main concern: what you want, is an effective barrier so that your air filters do not bring in ambient air from the engine space.

 

Metals are excellent conductors....but the air is moving fast enough that the conduction rate of the metal has negligible impact on the IAT's.

 

aaahh, meant conductors. thanks for the correction.

 

Anyone see these before?



Someone posted this picture at another 350Z site. I searched here and in the intake/exhaust forum, but could not find any mention of it. If not, is it a photoshop?

 

i would guess its a custom job. i also would guess that it didnt gain based on the ridiculous angle to the filter

 

that is not necessarily true because AIR travels through STATIC not FLOW

 

travel and static arent words that describe the same action, you should explain further

 

What kind of filters are you using? If you can supply them with Green double cones, put me on the list.

Brief Update switched to a shorter style intake I am very happy with the fitment etc and the use of a Standard K&N Filters. The CAI didn't work like I wanted. I couldn't fit a filter big enough on each side to give it the least restriction as possible. Switched to a shorter pipe length seemed to work like a charm especially with the filter being placed right behind the ducts.

Like I said before.. I really didn't have a plan to sell these but just made a set for my car. I am going to have them color matched for my ride so it will look pretty clean. You have no idea how expensive that tri stage paint can be.

Powder coating would probably be a better solution but I am just picky.
