nice side by side pics!

almost 2 years on here and havent seen that yet

 

LICP gains are an urban legend imho...

The only thing that makes sense is ~.01 or so sec of less lag because it's shorter than stock.

I got mine (used) because the stock one had a dent in it, and i will sell my nisei as soon as i install an ebay ams copy that i got for like $10. And because it's a better looking piece that i get to see ....never? Vendors that charge $200 for a bent pipe -

Another important thing is - Diameter of LICP does NOT matter, because all LICP's retain stock turbo outlet piece that is small. All you're doing by installing a piece like nisei that does not gradually increase in diameter but rather starts out 2.5" right away is creating potential pressure drop point.

 

This is incorrect. The Buschur unit replaces the stock turbo outlet with its own larger diamater outlet.

 

I'm sorry you're right some of the Buschur ones come up all the way to the turbo. It's most likely the only licp that does that though.

 

For example Buschur's 8 and 9 regular LICP is not like that:


Only the $270 BR Race one is and you have to have a BR Race FMIC....so i was mostly right.

 

im with you on the price they charge for bent pipe, but the fact of the larger pipe does help with lag, does help with better performance, i would say most gain would be with LICP, comp. FMIC, UICP, and of course a tune to pull the power out. I def. think that there will be more of a gain on the IX's than the VIII's.

 

I put the nisei LICP on my car yesterday. ~10whp gain according to DLL. My car only has a tannabe full exhaust, works drop in, and now a nisei LICP.

 

Could you post the power graph? Did you take into account weather and weight changes?

10 hp is nothing to complain about given the stealth nature of the mod.

 

This is uncorrected. Normally I hit around 320/315 with correction applied, less without. If I added correction these would almost be more like 340. Peak boost went up as much as .4 but I dont recall checking it this run so not sure. Also, this was the 4th 3rd gear pull in a row but it was the best. All of them were around 330 give or take a few whp. Also, feel free to critique my DLL setup as there's not alot of guidance for setting it up or on how to figure correction.

and with correction and less driver weight.

 

I was interested in the one power graph showing the before and after gains.

 

Wow, i cant beleive people think a licp gives them 10whp.... Get serious.

My dll fluctuates like 15hp from day to day. The only difference i make in my car are..... NONE. Besides maybe me wearing different clothes and shoes. Must be the nikes that make all that power.

Noone has ever proved any licp gain by dynoing the car with a stock one, then switching it to aftermarket and dynoing the car again right away.

I'm not saying it's a bad mod, I'm just saying stop giving people wrong ideas.

 

Honestly nj1266, I'll post a comparison later - I didnt log the car right before the install because I was in a hurry to install because I had limited time to do it. Basically we all have that occiasional high reading log but not 5 back to back runs all showing at least 10 more whp than our previous highest logged amount with no other changes to the vehicle. I've never logged close to 340whp on my Evo. Also, I made no tuning changes although I need to work on the timing some to get it to hold torque better through the run.

mplspilot.. Yes I know that datalogs can have varying power. Most differences in logs are related to inconsistant logging techniques and enviromental conditions which if you know what you are doing can be controlled. All I can say is that there is a real gain because I'm seeing numbers considerably higher than I've ever logged.

Here's someone else's gains
https://www.evolutionm.net/forums/sh...ght=LICP+gains

Here's mine. These are not back to back runs but I tried to find a similar temperature to compare.

 

This post has the LICP and FMIC installed at the same time. Results are inconclusive.

 

To the nay-sayers: I give up. Believe what you would like to believe. It's funny how my gains are very similar to his. Maybe you guys who are saying licp is not good just bought a poor LICP and we got the one that actually makes power.

To the OP: I experienced 10-15 whp gains as a result of licp installation. In addition to the DLL results my trap speeds also increased 3 mph. Went to the track last night and ran a new personal best 12.55 @ 109 with a 1.8 60ft (stock clutch) - My previous best was a 12.9 @ 106. Since the above logs were run I added 1* of timing from 5K- redline and have logged as high as 350whp but normally in the 340-345 range. Not too shabby for a IX with just a TBE, LICP, and Works drop-in.

 

^ I'm one of those ba-humbug guys. This stems from trying three different LICPs. I even have a thread about them. I didn't see any change at all.

In all honesty I think most of the gains people think they see after the install are probably from corrected boost leaks.

The pipe is shiney and lighter but it doesn't make more power. Like I said above I tired various pipes including the original AMS unit. They look better but perform the same.

I think you would be better off getting samco couplers and tbolt clamps than a new pipe.

I've gone back to the stock unit and I'm staying there. Because I road race and the engine bay sees extreme heat and lots of wiggling, I like the multiple stock mount points. I also like the heavy duty material that allows me to tighten my clamps up without damaging the pipe. The first time you blow a LICP coupler off you'll remember those words.

Trust me, its no fun getting towed to the pits, then pulling the splash guard off, and then wrenching on your wicked hot car when you could be out racing. This is especially true when you paid $350 for the track time.
