4GEN Liberty/Legacy - RAM INTAKE SYSTEM

[SubMeister]

+1 Good to see the R&D on this is continuing

[Tradewind]

Had hoped to complete this important pressure drop testing today

Will have to wait until the tune ROM is repaired, something has gone wrong with the file I was using and it wont load, meaning car isnt going anywhere with the CAI on until tune file is fixed

Very excited to see if loss reductions can be made and by how much

[Tradewind]

Here are the results of today's testing with high accuracy pressure test equipment. Measured in inches of H20

The result shows pressure rises (red line - CAI) of between 300 and 800%!

The car really comes alive insanely when it can breath this easy, the first few mins after loading the tune just blew me away like it did when I tested previously.

TO UNDERSTAND THE CHART - consider the top of the chart atmospheric pressure, and bottom of chart is BIG vacuum, for engine to breath easy (and make MORE power) you need a pressure line to be nearer to top of chart

Quite interesting how the start points are very close for both systems, up to 3000rpm there's nothing in it between the 2.

Now I have this data - I feel more certain about the attached dyno XRT did for me way back last year is correct. With pressure rises this massive (more air molecules in manifold) it can only be expected that 10Kw of extra power is possible - AND maybe more. I would expect I am likely to be overwhelming the stock cats through sheer extra flow with the headers and the CAI combo.

The next thing is - the BIG BLACK box that everyone removes when they add their 3" CAI pipes actually causes NO restriction and is best left ON the car. Removing it is only a bad thing, it would be same story for the H4s as well.

Yay for stealth!

Stealth and great plenum filling too

Time to take car for another blast and get the feeling all over again - sometimes testing isnt a pain

Nice work Tim.
I'm following this with great interest.



Also, are you testing along the intake to identify where the drop is occurring?

[Brunsy3.0]

I think there is a bit of a cult following here and for the headers. Could be a great combo pending these results and end cost

Agreed.

I would love to see someone take this all the way with a H6.
Headers, intake, E85 and a ton of dyno time.

[west_minist]

So is it the same design or v2?

Yes CAI, Headers and full exhaust system. An yes E85 tune would get you great results. I still think the SC is a better alternative.

[Tradewind]

This is SAME design CAI we tested from the beginning. I simply took it from storage box, fitted it back to car and made the new tests

We think we are doing marvels with the EZ30 (and we are) however, I am reasonably certain the EZ36 airbox is no better and motor has more capacity! This on an EZ36 would be even more amazing

so many h6's on here are gonna be powered by raptor soon

soooooo keen on both of these!

any photos from the testing?

[Tradewind]

I am pretty much sitting on the design on this one, I may be able to come forward with a partial shot that doesnt give too much away

Leave it with me for a bit

That might be teasing!

[Tradewind]

My car is away at the moment - so NO pictures just at the moment as I hadnt already taken any

A little alteration has seen the bonnet needing a respray!

Have made a MAJOR breakthrough on this project today - I expect to be able to bring the CAI to market in the next month - WOW - even I am amazed!!

[RX25SE]

Development or production breakthrough??
