from reading around i know that aftermarket licp help free up the stock pipe restriction. however, is the stock uicp restrictive and changing it out will will see any gain?

 

I hear the UICP does not really show any gains, however the LICP is a completely different story, put them on you will see gains.

 

The oem one has no restrictions, if u get the short route one it will prolly free 5whp, but u also need to switch to a small battery kit, the oem ones are good to 400 whp then the cplrs will start blowin(not all the time but i seen it happen), but other than that the oem one is pretty good

 

I changed out my UICP when I did the FMIC & LICP.
It may not add any hp but the stock upper pipe does blow off sometimes and the stock rubber hose does balloon under boost.

 

Nothing for the UICP and maybe a few of HP for a LICP on a stock-ish car.

 

Are these gains from the LICP real? Anyone test this?

 

the only time id go to a aftermarket UICP is when you use a tial bov cause you need the flange welded onto the pipe

 

Something to think about:

OEM piping on the IX, and VIII I know have alot of aluminum on them. The aluminum transfers a high degree of heat. Meaning heat from your engine really does a good job of getting through the aluminum into the air traveling towards your manifold.

My ETS Upper and Lower pipes are made of stainless steel. Stainless steel has a lower thermal transfer coefficient, meaning high engine temperatures will do less "damage" to the air thats been cooled by your FMIC.

 

Heat transfer works both ways. SS may take longer to heat up, but it also takes more time to cool down.

 

but with the intake stream you only want heat transfer from the fmic itself, not the plumbing.

 

Sorry, how does this relate to what I said?

 

Sure, it's been tested to some extent. Higher HP cars have been known to benefit significantly from an upgraded LICP. Mildly tuned stock-ish cars, not so much.

 

trying toget back on subject.....its there an advantage with going with a short routeother than looks and space.?

 

Number one gain from a shorter UICP is transient response.

 

Haven't installed mine yet, but i've heard there are some gains. I've been told the main benefit to having an aftermarket LICP is that the turbo will spool quicker.
