None. An UICP does virtually nothing. A LICP might net you a consistent 3-4whp in the current state of tune.

 

I also noticed a little bit quicker spool up with LICP.

 

Only issue I have ever seen with the stock UICP is the upper rubber hose will start to ballon to **** once you start getting some extra boost in the car.

Doesn't really have an effect as long as it stays together

 

I heard the stock IC is fine enough for ALOT of power? I know of a rally team running with stock headers and IC with more than 25k$ on the engine only. They have been running in rally since the evo 6 so they know alot about the car (and they are own a mitsubishi dealer).

So my question: why are people changing their stock IC unless they aim for monster power?

 

Heat soak is a beotch. Go out and log 10 back to back pulls you'll start to see the picture a little more clearly

 

Does this go the same for a stock turbo with just bolt-ons?

 

Sure, your setup won't see any significant gains, either, with just the piping.

 

You will deff notice a diffrence in spool time also.

Might need to upgrade some of the fuel system also if your still running on stock.

 

Can you point to a dynograph that illustrates such a thing? I've yet to see one that shows decreased spool time on a stock-ish car.

For pipes? Why?

 

Get the IC its worth it

 

I don't think you'll notice much difference just driving normally on the street. During street driving you're not likely to get heat soak.

I had my care tuned recently with only a mbc, downpipe back exhaust, test pipe and drop in k&n and made 298 on a mustang dyno. I'm sure a bigger intercooler will help with higher horsepower, but with the stock turbo on the street I think the stock intercooler is fine.

 

So your saying the stock intercooler will suffice? but up to what peak in whp ?

 

I think its worth the upgrade. I can't wait to upgrade from the Stock IC. I think you would be happy with the upgrade.
