We have just begun production of the lower IC pipe that we tested in the latest tech article in Modified. The picture below shows the pipe with silicon couplers, the kit will also include the necassary hose clamps. The piping used is 2.5" at the intercooler and features a long taper, smooth transition down to the turbo outlet size. These peices are the highest quality available.

Why spend money on a full piping kit if you don't need it, these pipes are shown to make very impressive HP for the price. In fact the lower pipe is worth 5 times the HP that the upper pie is worth. So for everyone looking for 10-15 extra whp, this is for you.



Pricing is as follows:

Regular Price will be: $225

Price for the first 20 orders: $199.95

They are scheduled to ship 4 weeks from today (feb 12th)

Will this bolt up to a stock IC? Is there any other mods necessary for applying this piece? AMS FMIC, cutting, heat shielding, etc?

At what boost levels did you get this 10-15 whp gain? What level of tune? Just peak power gains or across the boosted rev range?

A graph compare would be nice.

Thanks

 

Please show me, with graphic evidence, that the lower pipe is worth 5 times the HP that the upper pipe is worth. It's not that I don't believe you, it's just I'm a scientist. Show me this and you can count me as a customer for one lower IC pipe.

Ok I am not sure where the original test went to which was around the 330-350 whp range, but we did have these dyno sheets from when we started to pull parts off of the car and replace them with stock once we were pushing the limits of the turbo. I know that it is the most conventional way of testing the parts but you get the basic idea.

This first graph is the upper IC pipe that we installed and tested


And the second graph is with the stock upper pipe in place and the new lower pipe.


When we combined the 2 pipes together we saw an increase of only 1 average hp over just the lower pipe. I am still trying to dig up those original graphs from the 500 total dyno pulls we have made, as those will reflect the types of gains that you will see on the street and beleive it or not they are larger gains than you see here.

 

that would be aproximately 3 times as much power in my book. 5 times as much is about 167% more than it actaully is

 

That is why I said that I couldn't find the original results, and hey 3 or 5 times as much is proof enough for me.

What boost levels were you running during this test?

I appreciate your posts - great graphs! Different turbo, eh? It seems your piping really work in the high-flow/hp applications. What would the results be for us normal guys who have only done a turbo-back and and Xede? PS - give me your website, my google search failed to find you. Thanks

 

AMS's website is www.automotosports.com. There products are great and the quality is awesome.

 

On these particular dyno graphs it was around 25-26 lbs (holy maxed out stock turbo batman )

It's kind of funny that you ask that because the results are better at sligthly lower boost levels due to tha fact tha you aren't stressing out the stock turbo and running it out of it maximum efficiency "zone". From what we have seen here, most of our mods will give the biggest HP increase in the 21-23 psi range where the turbo shines. In my opinion at the point you are with your car and those mods, you will benefit most from and intercooler upgrade, the lower pipe, and a set of headstuds. With those mods and the fuel control that you already have your car should scream on 20-21 lbs.

as far as i concern, we are all normal guys with stock turbo, no matter what Xede or EMS or Safc or other engine manergament on it, we donot need to worry about getting after market FMIC till change to bigger turbo.
so, the intercooler piping is the best less expensive mod to push out all the power from the stock turbo. stock EVO's rubber piping is really suck(expendable), and upgraded piping will help you to hold you boost stronger and throttle body response quicker.

so far i really have great experience with AMS services.

Then what kind of gains can we see on a more normal car running 19psi??? How about one that isn't pushing 450hp already!

 

I would also like to know what gains is here to be seen on stock Evo and or Evo running 20psi to redline?

 

Are the lower i/c pipes ready for shipment yet???
