To the masses that don't know any better, Hennessy is a big name like Saleen or Roush. It pains me to even put their name in a sentence with the other two.

I might want one of those once I do my BOV's.
Can't wait to see the CAI you guys come up with...
BiGMaC said:The biggest problem with the stock box is the restricted intake and the "saxophone" coming out... 68GT definitely has the idea.. that's what 4DR and I want to eliminate as well in the new dual CAI under development.
A lot of the idea can be seen in the install instruction manual for the Hennessey CAI although they still use the OEM intake cut off the box :naughty: ... they do eliminate the saxophone with it's 180 degree curve and tapering diameter. :thumb: Pics here in their install manual on pages 3 and 4. Plus they have a separate tube for each turbo and eliminate the crankcase recirc into induction air that is present on the stock intake. The Hennessey pics are here and include SHO and MKS

bpd also did and still has a "one of" single intake... I think it's in a "how to" thread here.
As far as the new one 4DR has been working on (and I joined in on at his invitation) should have all the info from Jeremy at BMR so we can have a custom fab of the first one started in about 2 weeks... We'll have Jeremy dyno my SHO stock and then again with the new dual CAI on the same day... and we are also talking about a third step: having it coated and dynoing again to see if it is worth doing the thermal coating. Along the way we'll be doing underhood temp studies for the PPE coating of my downpipes too... More on this last stuff later.

Once it is finished and we see dyno gains to justify purchase ..... there goes my money ! !

The tb inlet pipe isn't cheap... Its $160 bucks on fords website. Probably better off buying part of the hotpipe kit.
First, I am completely aware of the dynos (albeit not on '13 SHOs by any of the major manufacturers) that are available for K&N, AirAid, and Hennessey CAIs and have corresponded with all of them. I'm not trying to debate the idea of a CAI or dis anyone at all, yes… denser air means more power, and there are other reasons than just air to have one. This is just what happened…. and my thoughts on what else we need to know.
Here's an interesting performance fact… at least on my '13 SHO… regarding turbo inlets/air induction. During the testing done recently on multiple sets of downpipes at Black Market Racing (thanks 4DR) using my SHO with stock tune we did this test:
On one occasion after the pull with the pipes we completely disconnected the air intake box from the "saxophone" turbo intake… no filter, no box, and the hood was up with a fan blowing on the engine, temp was about 79 degrees and humidity was about 30%…… Just the big open pipe drawing air.
We were astonished that the difference was less than 3 HP when compared to the pull with the OEM Ford induction in place… This was with stock tune and no other performance mods on the car at the time.
After I get tuned (with down pipe adjustment, but all O2 sensors on) we will be testing all the pipes again as we feel the gains will be larger. I hope Mike and Jeremy will be agreeable to testing at this time. I actually am starting to feel that the major restriction is after the SHO filter box. If the tune doesn't make a difference I'll be pretty sure that we need to work at least as hard on the portion of the air induction after the filter. In fact I think bpd decided this when he built his "one of" custom CAI.

This doesn't surprise me.
The stock piece may not be flashy but it is very well engineered especially when it comes to heat soak.
The only reason I reinstalled my k&n is for sound and I like how it looks.
The question is where CAI manufacturers are pulling their "dyno" numbers from.
My guess is out of their sphincters, and this proves it.
Has anyone paid close attention to the POS dyno graph k&n provides?
It's conveniently missing some needed data.
I did not.SHOdded said:And I am sure you can get a 3-4 mpg improvement in fuel economy too just by changing to a CAI kit.
I swear the car has better throttle response with the stock intake, which will be going back on when the temps rise.

I think Shodded was kidding.
I put my stock box back in.

I did not care for the sound. The pipes sound much better.

I love the sound with all the plumbing done and the VTA... Much more aggressive with the noise maker gone, like a larger engine almost, and the sound is more with me and beside me, rather than in front of me, when I accelerate hard at any speed, but completely quiet cruising.

you say noise maker, but it's actually a baffle to quieten the intake noise right ?
DJE why did you remove yours ? "the pipes sound much better" ?? downpipes / exhaust sound ?
