intake hack

[kenny's 370z]

well,i first tried the k&N drop ins.then bought the z1 tubes.i honestly didnt feel much.so after many observations of all the different intakes on this forum including custom.i decided to try my own.i can tell you that it does pull harder than the k&n drop ins and maf tubes without question.and its not a placebo effect either cause i really cant hear the intake because of my exhaust.it pulls so much better and easier now.

sure it's not perfect but its not throwing any cel's and it does the trick.even on the interstate,it pulls better.so anyway,i tried to copy the k&n typhoons as much as i could just from the pics.the filter has a 3" opening connected to about 2" of aluminum pipe that you can't see.from there i have silicone reducers going from 3" down to 2.5" connecting it to the hacked oem pipe.everything is smooth inside and works great.dont have the money right now for the k&n's so this will do for now.thought i would share.and yes,i know alot of people prefer the gen 3's cause of their local providing cold air and such.but honestly,i didnt feel any power loss over the drop ins.only felt gains.here is a pic.

doesnt look bad at all. The couplings look a little off but who cares. As long as you like thats all that matters.

thanks. it was an experiment that worked out very well on the performance side as i just didnt feel the drop ins were doing me justice.i will have to wait and see what it does after i get a full exhaust as to whether i will keep it or not.for now,im not complaining.

Kenny's at it again...

Whats the deal with smog in your state? In California that would not pass smog without a carb sticker.

no cel's and a clean exhaust gas is all i have to worry about.

I like the way Kenny thinks!!

I experimented quite a bit with this method, I can pretty much guarantee you that you lost power doing that. Likewise, another member on here did something similar, and also saw losses up top.

The MAF sensors are VERY sensitive to airflow tumble effects. In short, if those intakes are moving around and or you relocated the MAF sensors, the MAF misreads will cost you power.

Also, the filters are not heat shielded, and that too is likely to cost you power.

Check out my proven power dyno thread (search my username and that); the K&N filters actually add quite a bit of power, and those plus smooth tubes are within striking distance of the G3's at half the cost.

Attempting to rate the impact of tuning mods with the butt dyno is ill advised -- if you compare that to stock + K&N on a dyno, odds are very good you will see big loss in power up top.

It will SOUND mean, and FEEL like its pulling harder, but its 50-50 at best that it's performing any better.

Let the Frankenstein intake live and he might just end up with an innovation that passes all of our expectations. I enjoy seeing fellow inventor and experiments.

i appreciate the info,i do .but it does pull harder where i need it and the filters do have some heat shielding.the intakes are stationary and the airflow is pretty smooth.if in fact i feel like im losing power,i will rid these intakes.for now though until i can get the typhoons,i will enjoy the power this setup provides.

EDIT;today is the first day i had a long distance ride with these intakes.i didnt feel any power loss up top to 140 cause thats where i let off.car just feels 100% better even in 90 degree heat.i did notice about 1 1/2 seconds worth of heat soak after sitting at a light upon immediate acceleration but makes up for it everywhere else.me like.(this is not my first rodeo making intakes).

today i was looking at my set up and i decided to improve on it more.so i put the filters as far away as possible from the hood where heat gathers.filters stayed cold as ice tonight with ambient at 65.they were cold like i was holding the filter out the window while driving. when i got home and popped the hood,its like they were sitting in ice.i do have fender liner vents as well and the vacuum that is created there,its pulling more air from the oem cold air vents.

after what jordo said,i made sure the intakes would not move.i simply loosened the z1 tubes at the throttle body,and turn the tubes inwards putting the filters right in front of the cold air vents(after modifying them as well) and the tip of the filters are braced on the part of the oem box i retained.

still havnt experienced any power loss and since i buried the filters,my gas mileage also went up even at 100 plus.anyway,im just sharing my project thats working great for me..i feel that after i get the pullies,m370,exhaust,and a tune,this car will be scary to drive in 65 degree ambient.

I have to ask... Why?

For $325 you can get the K&N Typhoon that looks a lot better and has real engineering behind it. Plus it fits perfectly and has heat shields.

To each his own, but for a little more, I would have gone with the K&N.

edit; because these pull way better than the drop ins and the k&n typhoons sit way too high towards the hood.im keeping my custom setup.3 days of driving with them now and the car pulls hard enough to impress me and thats saying ALOT.
