Maf pipes
 

Has anyone dynoed to see if silicone piping really makes a difference. Are these worth paying $100 for. THANKS.

I didn't find any dyno reports but I didn't dig very deep. https://www.google.com/#q=site%3Athe370z.com+HPS

A LOT of people think they're amazing. With pretty "good" dyno sheets.


If you have the money to buy a real intake, do it. If not, K&Ns and the post MAF tubes

I figure if it's good enough for tiddies, it's good enough for me.

We all know that the silicone gains for tiddies are real; seems it should work for Zs as well.

:iagree:

get something better, i highly doubt you'll gain anything noticeable from silicone tubes

I have them, I have not ran on a dyno to tell you anything. I didn't think they made a difference at all. I installed K&N filters first and then added them, never reset ECU or anything. Figured I would at least feel something with the two but I did not, the intake nose was still the same.

I bought them as my first mod used for $100 w/ K&N's. I switched to stillens right before my tune.

fuk K&N's

says the guy with an ebay intake on his Nismo :shakes head:

I'm willing to bet that the intake that was GIVEN to me will dyno more than Silicone tubes and the intakes that were given to me cost like $10 more as opposed to silicone tubes.

Seriously I saw a dyno on a 370z Facebook page with drop ins and HPS tubes that gave 3whp over his FI exhaust setup with stock intakes.

IMO not worth the $200 someone will spend on drop ins and silicone tubes.

Sure they will. With the hood open. Once you shut the hood you'll be down on power compared to a stock intake since you're sucking hot air. Whether you bought them, someone gave them to you or they fell from the sky, you should take them off and sell them to someone who doesn't understand how cars work.

I have them and I can't complain, they're not going to give you the power as per say a Stillen Gen3 CAI would give but better than a Short Ram?? HELL YEA!....my first intake set up was the K&N short ram, Worst mistake I could make my car over heated and shut off due those things....so I decided to go with my current setup since I HAVENT FOUND ANYONE selling Gen3 CAI on the parts for sale section and well I can't complain its actually very benificial, I will be dynoing soon and definitely want to share this to the the Z community but after I save a few bucks to install my nitrous kit and a tune at jtran. My Opinion and Experience with post mafs and drop ins first hand have been the best choice I've made atm if of course money seems to be an issue in getting the Stillen CAI.

just want to inform you, i see IATs 8 above ambient when moving(i have logs to back this up as well), sitting in traffic is the only time i heat soak and even then once i start moving it drops fast, one thing no one can measure with a dyno is the ram air effect, there are no dyno fans big enough and push enough air to make a difference, that holds true for both the stock box and short ram intakes

yes im an advocate for CAIs, yes if i was buying one i would bought a CAI, but compared to MAF tubes id buy ebay short rams for the extra $10(and some of them are actually the same price as MAF tubes)

heck for a little more you can convert those short rams into cold air intakes using some silicone couplers and pipes that can be bought for under $50 and still be under the cost for maf tubes and drop ins

seriously maf tubes and drop ins are a joke, id recommend drop ins for someone who wants to save money on filters but thats about it

if i had the time and patience to dig through 3 weeks of facebook posts and comments, id post that guys dyno just to show how useless they are when it comes to making power

So you fixed the problem that had you seeing 160 degree IATs?

yep, it was the filter i was using, i moved from a pod filter to a cone filter, i think it was because there was no opening in the top of the filter where the air gets rammed into it was left to suck in hot engine air

i did take the intakes off for a period of time but than randomly i decided to buy 2 cone style filters(specter air filters at orileys) and put the intakes back on, it made a world of difference

the most i have seen is 130 IATs and that was literally in dead stop for 30 mins cause CHP had shut down the highway temporarily cause of an accident(thankfully it wasnt long)

ill wait until summer to see what IATs are then but right now my IATs are the same as the stock box from what i logged and im extremely happy with the intakes, although i do plan on extending them using similar parts Synolimit(only difference is it being in bigger size) used so i can have a true cold air intake until i supercharge

let's see your log from december 30th from around 19:00

you should follow your own advice:

and when did i post that? i can tell you that was months before i saw someone actually dyno that set up, hate to break it to you but people's opinions change and i feel that mod is stupid and a waste of money for a gain of 3whp over their a full FI Exhaust, at least now i do

also i dont have a log on that day, i dont run torque all the time but here is a log from DEC 26

the highest IAT i saw was 24C which is 75F and i saw as low as 57F(14C), not bad imo for something that sucks in 200+ engine bay temps all the time

INTERESTING you say this as I too bought the spectre filter but it didn't fit my Ram Air Tubes because filter was too big....I'm curious to know how you fitted it?

what was your piping size? my intake piping size is 2.75in with it tapering down to 2.5in at the MAF, i bought a 3in filter but since it was only .25in off it fit just fine, no leaks or what not

if your intake piping is 2.5in or within .25in smaller of it, you want to get their 2.5in filter

you were driving 100mph at 2k RPM's and you're still not even at ambient temps? this is a really bad example.

I will check the pipe size I have it stored in a storage on the other side of town lmao I just said "Screw you RamAir and rust for all I care" Lmfao bad experiences man, not bashing the ram air, but I was left over heated in a part of my county that is close to mexico soooo yeaaaa NO BUENO that day....

thats 100kph or 60mph(was still fixing some of bugs with the app not uploading the proper measurements), at 100mph id be well above 3k in 6th

stock boxes dont get to ambient temps anyways, the most they are at are 8 above from what i saw from previous logs

like i said, im seeing the same data as stock boxes but the butt dyno says there is more power, i definitely noticed a difference in torque

there is a log from the DEC 5, stock boxes and this was when it was close to 37 out iirc and the lowest i see is 11C(51F)

Shows quite a bit more than a 3 whp increase here.

Iirc those dynos are from a couple years ago and they are on a stock 370z, as you can tell from the dyno, heck I think they are from the original maf tube and drop ins thread.

What would be interesting to see is maf tubes over stock intakes on a car with other mods and than see the dyno. I doubt anyone will see more than 5whp on top of their current setup and that's being very optimistic(and even than 5whp is is like changing from a dirty filter to a clean one)

For a DD, probably not worth the cost for a very few more HP. But it's an easy mod and, if you like the look, why not?

Personally, I'd put the money toward an exhaust. You won't gain a lot of HP that way either, but it will sound better. ;)

You're not going to see much in the way of gains with cheap, easy solutions. Nissan has already picked all the low-hanging fruit.

ya when i had the K&N pod filters on there i was running into problems with acceleration, heat soak, ect.

i dont know what caused me to put the intakes back on my car with a different filter, i was just at o'rileys and bought the filters randomly and slapped everything back on my car

either way when im done fixing my transmission ill be extending out the SRI into CAI since it costs less than $50 for me to do it, if you get the chance to id suggest you do that as well since its only gonna be better for the car anyways
