Ok Guys..Time to vote please. Short or Long Route Piping??

[BigLGST]

Ok man....I just wanted to know everyones opinions. Is short route piping really that much better than standard piping. I think short route is SOOOOOOOOOOO "over rated"!! But I dont know is it just me or wtf????? Like any1 have some numbers I can take a look at??? Cuz I just been arguin with a friend of mine for sooooo long about this and he says its 10x better than standard i just dont see how its sooo much better of course its a shorter route but what does it matter???????

 

[eclipsegsx9797]

with short route it is better sense it is alot less pipes for air to go through to start making power, makes the engine cleaner and helps with spool up.

The only reason to go with long route piping, that I can see, is that if you already have a UICP and BOV combo you're in love with and don't want to get rid of it. Otherwise, short route is the way to go. It clears up space in the wheel well where the stock SMIC was so you can put something else there, such as a cold air intake. Or, if you're A/T, a nice aftermarket tranny cooler.

 

[BigLGST]

Ok maybe good points, but I just dont see how much faster it can get there from a pipe being about 6 inches shorter. That just doesnt seem worth it. Plus w/ long route you can put a GM MAS on the UICP and and "removing the MAF from the intake means just filter straight to the turbo" which in means you have no restrictions which means you would have a faster spool up. I just think this long route piping would perform A LOT better than short.

 

[cait sith]

It's not the straight pipes that cause the pressure drop as much as the BENDS that cause the pressure drop.

 

[eclipsegsx9797]

yep short route less pressure loss witch will make more power and spool up no other way to go then short unless u have a greddy fmic that goes to the stock location

 

[kpt4321]

Long route has no benefits, they ONLY reason it is used is so you can still keep the stock piping to save money.

 

[eclipsegsx9797]

yep ^

 

[doug]

Why would you not be able to use the MAFT with short-route piping?

 

[eclipsegsx9797]

ya u could use the gm maft set up with a short route just get the pipes cut between the t/b and the bov and hook up the gm mas there u go same thing and still better spool up sense its shorter

 

[Defiant]

Shorter route = less volume to pressurize under boost.

 

[bigfoot]

You convinced me BigLGST. I think the long route is waaaaaaaaaaay better for you. I however, will go short route. Everything I have ever read said that you want the turbo as close to the TB as possible for a responsive motor.

 

[DSMJim]

From what I understand, every bend is like a 3 foot section of pipe so those extra 3 bends is like adding 9 feet to your intercooler pipes.

 

[eclipsegsx9797]

this is easy to decide i mean wouldnt u rather walk in a straight line to the store instead of around a few blocks. i know i would rather walk straight because its easier, less tiring, plus its quicker same thing with the piping, short route is quicker, helps the engine keep moving. and all around looks better . its ok leo your fmic is acutally a goo long route all your piping is on one side so its not like the greddy.

 

[slodsm]

DSMparts.com already has a pipe to be used as a blow through with a short route front mount too so that can't even be argued anymore.

 

[eclipsegsx9797]

do they realy i have never seen it on there site is it up there

 

[slodsm]

Sorry bro, just went back and checked it out, I didn't even notice you had a 2g, its for a 1g with a front mount. It would probably work anyway but it is listed for a 1g under intercooler pipes.

 

[MJD_GST]

Not trying to jack the thread, but does anyone even manuacture short route piping for a 2g?

They both offer FMIC kits with short route piping, and the AHP site has pics. It also makes it very easy to setup a blow-through style MAF also. Just requires a little trimming and some couplers for the MAF. I would like to see how the SBR FMIC is routed, although AHP will route the race kit any way you want it.

Short Route really isn't a whole lot shorter...but it does look nicer and does have less bends.

Is spool up really faster....no
Think about it, you have an engine that is using up 2.0L of air every 4 revs...right .5L per cyl. Each cylinder fires once every 2 revs. So in 4 revs the engine has fired each cyl once...ok.

Your at 3000rpms. Close to spool up time for smaller turbos. 3000/2=1500 (I divided by two because other wise I divide by 4 revs and multiply by 2 liters...) I did the math right, right?

so that "means" your engine uses 1500L of air/min, throw boost into it, and your turbo must be able to push more than that amount of air to create boost...

That is a basic idea...you can go and argue about throtle position, Volumetric effiency, head flow ratings...etc. Which would probably turn out that the car is using considerably less than 1500L air/min at 3000rpms but the idea remains the same.

The amount of piping is very small, and its not hard to "fill" the pipes with pressure, whether long or short...and would not effect spool up time. The size of the IC may effect pressure drop across it...
I think the main benifits of short route are, less clutter, and probably better flowing...especially 2.5".

So it looks like the vote is 11-1 so far, plus your friend.

Wrong.

Each cylinder fires once every 2 revs, which means that in 2 revs the motor has fired each cylinder once, and in 4 revs it has fired each cylinder twice.

One rev means 360 degrees of crank rotation, when means that all of the pistons come to TDC. Half of them fire.

 

[eclipsegsx9797]

im sure if more people responded to this it would be like 200-1 im his friend the on that says that short route is better then long and this thread just proves it i love being right

Technically, a bunch of internet jockeys (me included) chiming in with their opinion doesn't "prove" anything, but I understand what you're saying.

Short pipe. it looks cleaner.
