Motordyne ART pipes review-Dyno inside
 

OK, well i took the day off today to go ahead and do a review...temp outside was about 75 with 50% humidity, 93 octane on a DYNOjet. I have the print outs which i will scan tomorrow but here is the actually file...its a little messy, its like 6 pulls on on chart, but they were having some problems with the system...And as before with my previous dyno exp there, they had problems with TQ reading :( BUT the HP gains were Solid...AGAIN sorry for the messy chart( i will clear it up for tomorrow)

MODS:
AFE drop in
HPS post MAFS
ART PIPES
everything else is stock

Final numbers with those 3 mods was 296rwhp

my previous was 285rwhp wihtout the ART pipes

i dont have a scanner here at home so i will have to wait till i get to work tomorrow to upload the printouts

my next mod will be a Motordyne XYZ pipe and Top Speed exhuast and then a tune[IMG]http://img101.imageshack.us/img101/867/gabe370z.png[/IMG]

11 hp isn't bad at all! I can't wait to get mine I wish they would hurry along the production of these things.

when are you planing on getting the TS cbe?

yeah definatly good! Am very pleased with theses pipes

its on order...should be here SAT! The XYZ though is on back order for a couple of months

What are ART pipes?

Intake/Exhaust Components - MotorDyne Engineering

check them out

Nice numbers gabe!

thanks man!

I should also add that the 289 numbers were done in 4th gear...i had to tell them 5th is 1:1.... i hit 296 back to back

any bad hiss with these pipes? since i added the nismo s-tune exhaust, i have zilch for hiss and would like to keep it that way. great #'s btw!

No, Zero hiss! Just a smooth tone...love the way these pipes sound

Nice resonated Y pipe Motordyne has. That would be great for people trying quiet down their system with HFC's.

GZ3 I cant see pictures!!

but glad to see its done nicely, gratz

Dang..not bad

you cant see the dyno graph??

check back in tomorrow... i will have the actually print out loaded up...much easier to read

296 - exact the same as me with these fitted... ;-) Nice

You will love the TS CBE, I am really interested to see how it sounds with these.

Hey man,

YGPM

Had these on my 350Z and they were great.

Looking forward to cleaner dyno chart. Curious what the area separation is to see how much power was gained throughout.

Same here!

Keith, what mods did you have when you got 296?

ART + Y pipe dude

sweet....i think am just gonna get the OBX or the JIC....no drop ins or anythng?

here is a cleared sheet, this is one of my baselines vs drop ins, Post Mafs and ART pipes

If you can get me the drfs I can make all sorts of graphs that point to gains trhoughout the rev range. Also, I might be able to clean up the weird tirque data -- it might have done that because the dyno was torque over wheel speed rather than engine RPM.

Also... a couple of those runs are in a different gear -- looks like 4th (up to 125) and 5th (over 140).

11 hp is a great gain. But thats around the same as most people are seeing with plain TP. Correct me if I am wrong? But not having rasp might be worth the price alone.

I called them, they said they would send them over this afternoon. And yeah the 289 was done in 4th, i reminded them that 1:1 is 5th on 6mt 370...i dont understand why they have so trouble with the TQ reading

Is that JUST test pipes? Or after exhaust? That could make a big difference.

On the 350z forum, the ART pipes definitely made like 5-6whp more than the test pipes.

Thats just Test Pipes.

completely stock exhaust other than ART pipes

i have drop ins and post mafs tubes

After you do the catback you will feel great gains. :tup:

cant wait! it should be here tomorrow ......will you be joining the Dark side?

Well, I don't have a 370z. My friend (red6spd) has one so I said wth and joined lol. I have an Accord 6MT :p

I know a decent amount about the VQ motors though and can say you will LOVE your full exhaust.

It might smooth once converted to RPM. Could be a glitch in interpolating by MPH with data from two different gears -- dunno, I'll play with it and try to fix when I get them.

Oh, and thanks again -- I appreciate it!

I apologize if this has been covered before, but can someone explain the design of these pipes? They certainly are unique, and I'm assuming the construction has to do with fluid dynamics to maximize flow and create a specific sound but they do look a bit odd.

so these would show greater gains on my Nismo over a standard 370z?
because 11hp is a pretty decent gain especially for the price.
and noob question, but what are post mafs tubes..
Im going to guess the piping from behind the MAF to the intake mani? or am i way off?

You are correct. It seems that with replacing the stock tubes and air filter with a drop-in you can gain around 8 whp. True the stillen CAI gains 17.5 at the top, but the install/filter cleaning requires bumper removal (not a big deal) as well as some dremel work on the core support (install). Many people on here are going with just hoses and drop-ins as their intake mod as the stock set-up is already pretty efficient. I think I may do the same. And you save at least $300 in the process.

excellent. and the drop in's are just a better flowing filter?
sorry, for sounding so ignorant on the subject. I'm just used to CAI.

The drop-in's flow better and the pipes provide for a smoother path of air inlet.
