Hello!

So I am currently using the ETS Long route UICP for the stock battery. I got this setup b/c I read and was told that small batteries suck.

Now i've been really toying w/ the idea of getting a short route and maybe moving my battery to the trunk due to "better gains."

Question I have is... is there really a performance gain with going w/ a short route vs the piping I have right now. Like eventually i'll do it but is it worth spending another $3xx.00, buying the pipe, moving my battery to the trunk, then selling the long route pipe,etc ,etc. Would I be better buying something useful like spoolin up cop kit or something. I was thinking of getting the CBRD short route which doesnt need battery relocated but thats almost $400!!

This summer im doing Red, GSC S2's and meth....if that factors anything into the equation lol.

thoughts, suggestions.....

 

ours is more expensive because of the battery tray-

if you want to trim the corner off of the factory tray then you dont need it- that takes 68.00 off-

ok but is there a difference in performance vs a long route UICP that others sell?

 

There will be increased throttle response. I believe a little decrease in spool due to the fact that the air has less obstructions from bends and less distance to travel.

 

1) There wont be much in gains from the UICP routing.

2) the weight distribution benefit will outweigh the pipe routing.

3) I can save you hundreds more! The spoolin up wont be neccessary if you do a SD Tune (I reccomend English Racing). You can talk to them, they dont really see any gains with switching to the prius plug/coil setup compared to the OEM setup on SD tune.

4) If you are dead set on the UICP purchase then ETS has 20% off on their piping (http://www.extremeturbosystems.com/)

 

You won't gain much by going from the ETS long route UICP to a short route design. As others have pointed out there will be some minimal gains.

Living in Alberta I don't blame you for not using a mini battery. I use one but I wouldn't in a colder climate. The CRBD UICP looks like a nice option for the standard battery, but you should check to be sure that it is compatible with your intake pipe arrangement.

 

I would love to try SD and ER, however my issue is that ER doesnt like tuning ECU Controlled boost. I run meth, so I kinda need ECU Controlled boost for my fail safes.


Thanks for the explanation !

 

I was also wondering this.. I tuned on stock UICP on e85 with 30lbs of boost and ran into no problems.. I think its more of looks then power.

 

I believe that your gains would be very minimal. Even the ETS UICP short route claims "12% better flow over stock". I don't even know if you'd be able to notice that kind of difference. If anyone knows otherwise from experience, please share. I was wondering the same question not too long ago and this was the type of answer I gathered.

 

Keeping the same tune (not the best answer but...) I noticed a HUGE difference on top-end (no numbers sorry/but you can take my word for it ) when I swapped my stock upper UICP half with a Perrin Boost tube (the "GIANT silicone coupler" as someone stated here a while back lol). It's massive and extemely smooth in diameter transitions. Too bad it's been discontinued and there isn't much info. It also made taking it off and on trivial.

More importantly, smooth transition and performance to heat cycle ratio should be a buying and installing factor and the least amount of hump type couplings should also be a factor. On a final 3 dyno pulls a stock UICP may be great, but over time, the rubberized stuff will get spongy and air transition from the sections will get screwd up during expansion.

Mini bat are fine on a car that is driven a lot. It's only when they sit for mons at s time that they can suck. I have had a Ets mini bat on my evo for 60k and even on e85 it's fine.

I hate batteries in the trunk. Adds a ton of weight with all the cables and crap, never really looks clean, and to make your car leagle at the track sucks.

I like the mini bat and shout route for weight and how much cleaner the engine bay looks.

 

what if you run a sub? Think its recommended to run a mini battery?

 

Guess it depends on how large the system is. If the car is running I don't see a problem with a sub. If you ever run it with the car off it would be dead very fast.

 

lol true! Its just a 12" sub. Now heres the million dollar question for ya...

With me currently having the long route piping, thinks its worth it for me to get a short route? Im running GSC S2 cams, FP red + meth.

 

IMO it's not worth the money for whatever gains you might get. You already have a aftermarket UICP so why spend even more money for such small gains. I have the ETS stock route UICP as well and I would never swap it out for the short route, plus I think the short route piping looks ugly in the engine bay. I'm doing a HTA green and cams soon and I see no reason to swap UICP's.
