Hoping for your positive results, hell, even if this adds very little to no power overall, if it at least enables the stockers to breath to redline, that, in and of itself is a plus!!!

Good luck and thanks for posting up your process and parts being used.

Good work.
Even if it only lower the WGDC needed at redline, it's a good thing.

Do the 1.75" elbows fit over the inlets easily? I thought they'd be closer to 2".

They slip on great, nice and snug. The OEM inlet has an OD of 1.8" so it is within the spec of the coupler. Any bigger and you would risk them falling off IMHO, I prefer to have a snug fit without the clamp, that way I don't have to torque the hell out of it.

I also did not want to risk the elbow ever popping off. As many have mentioned, the front is a cakewalk, getting to the rear is not fun, even with the subframe out you are having to twist and turn.

Are you removing the waterpump and tstat for the front inlet?

No, the front is exceptionally easy to access. Removing the front inlet pipe is a little work but installing the new silicone is very simple. I am AT with an oil cooler so I have plenty of things stuff in there. I will post a few more pics here soon.

As many have mentioned, I am sure you could install all of this with the subframe in place but I sure as hell would not want to try it The rear at least.

SUBSCRIBED, looking like a healthy alternative I thought about doing this for a while but **** just keeps getting piled on top of me (Baby, adopting a teenage blah blah ...) If this works out, I would gladly hand my wallet over to you! haha

Same thing here, I relocated the front months ago as well as relocating the coolant and steering tank.

I considered going to a 2.5" pipe but I just did not see the reason to clutter things up even more and the actual turbo inlet is only around 1.5". I should have the car up and running either tonight or tomorrow.

Results should be easy to notice on the dyno. While I did not have a baseline there are 100's of cars with my mods and oem inlets.

Thanks for the additional pics... Looks great in place and can't wait to see more.. However I fear one problem here for us RHD guys, that's the steering rack being on this side and the rod possibly being in the way...

However, using 2 separate runners out each turbo to its own filter could squeeze past it...just a thought for further RnD..

Sweet, I've thought about mating some aluminum piping together to do the same thing in the past. Just never found the time to do it. Nice to see someone else thinking on the same page!!! Not too mention, about $1400 cheaper than like products on the market lol

The engine moves. If you are going to make it attach you are going to need a flex section of some sort. It generally is a bad idea to attach something to the engine and frame without something that can flex.

If this provides results I am sure you could get plenty of orders.

I would prefer two separate in takes if possible. It may not be without a custom fab job.

You ran CFD on a the N54 inlet length to diameter aspect ratio at these flow speeds? If you own the CFD package to do so, that's awesome, but this is a simple hand calc. I'm really just asking because I buy and sell analysis codes and I know what CFD costs. It ain't like buying microsoft excel.

The silicone couplers will flex enough. Just think...your fmic is hard mounted but the coupler is what's providing the flex from charge to the intercooler

My guess would be the CFD function in SolidWorks or some other 3D design program. Honestly, I wanted to go equal length and combine the intakes, thinking along the lines of an X/H pipe. Time will tell.

Everything is installed and fits well. Should fire her up tomorrow.

Nice. Programs can tell you all sorts of ****, but testing is optimal for real world numbers. I wasn't knocking on TFT at all. The product seems to be very good.

Equal length is a good start and the combination intake could help pressure distribution (but I doubt it). Not a bad thing, you just lose the cool look of duel intakes. They always say: the dyno will tell the truth.

Everything is mounted, and clearance is good. I ended up having to add an additional silicone joint to align things the way I wanted. That said it ended up being where I wanted to have silicone anyways.

PCV is setup just not connected at the moment. I will be adding some heat shields etc in the next few week, in addition to the wrapped *********.

I experienced some strange buffering/surge with un-equal length separate inlets. No clue if there was a correlation but hopefully I will find out soon.







More to come!

Looks legit! Did you run the PVC line under the tubing? What are your plans for the reservoir? Keep the pictures coming can't wait to see it all buttoned up.

The PCV runs under the intake to the main connector between the elbow and the filter. Reservoir and steering have luckily been relocated for a while now. Buttoning everything up today to hopefully start her up!

Here are the coolant expansion tank relocation brackets. Just some basic silicone hose and couplers to get everything run together. I will continue to look at a few OEM options for connecters to cleanly tie into the system. As it is you don't see anything, I know it is there .

very interesting! I will definitely be staying tuned for updates. im just curious to see if the silicone elbows will hold up to all that heat.

I know vtt is using silicone intakes as well but I wonder if they avoid heat because they are routed differently.

good work!
