idk if i would buy one or not. I have a hard inlet from agency power (not that smooth internally, but it works) but knowing how high quality your products are i'd definitley consider adding it when i change the fuel system to go with flex fuel since the manifold will already be off.

in for information and interest. I would love to have a metal inlet pipe for my plastic mani (lgt/08+wrx).....metal reflects sound better and should make the turbo spool louder.

Wish this option was around years ago when I replaced the OEM inlet back in 2012.

Just to verify will this fit other vf style turbo's, in a 05-09 Legacy GT, Outback XT? That would increase the market.

I am into the stock air box with modified intake tract idea so I am into this if I end up modifying the car that far.

If the price creeps up too high it makes the HKS dry carbon one more appealing as carbon is arguably a preferable material for the application.

That being said, I still want an sti aftercooler

I can't see the pics in the OP, I'm super interested in at least seeing those but also would be interested in purchasing the hard inlet.

Seems like a bad idea. There are lots of turbo inlets out there already. Quite late in the EJ game to invest in making hard inlets. I might buy one if they already existed, but I wouldn't suggest investing a lot into making a new part for an old engine platform that isn't worth the higher price(for most users).

What are the real performance numbers? What kind of flow do you actually need to get before you see inlet collapsing issues? I would think it's quite high and doesn't actually apply to most people.

More importantly, if the inlet pressure is getting so low that the silicone inlet is collapsing, then the inlet needs to be larger. Making a hard inlet would eliminate collapsing, but that doesn't fix the problem that the inlet is too restrictive. With no collapsing, you could push the turbo harder, but the higher pressure ratio increases the work the turbo has to do and reduces the efficiency of the whole system.

If you added some intake manifold spacers to fit a larger inlet, then you still have the bottleneck at the bend behind the PS pump. I guess you could add a couple bypass hoses to get some more flow around that, but that is getting complicated and making a rotated setup look easy.

So many inlets have come and gone over time. Hard inlets are few, and none install as easy as ours. Not saying ours is magic, just different. The engine is old, but it's still in new 2021 models and the meat of our customers are those just out of their warranty. So I think we still have a few more years before the EJ market starts to drop.

We say 14whp and 19wtq on a stage 1 STi. These are averages over several pulls, not cherry picked numbers. We're going to release all our data once we have a release date for the product, which should be soon.

No one can answer the collapse question because it depends on the inlet you use. Crappy ebay unit would collapse long before a quality brand. We've run 600whp through the Perrin and it didn't collapse.

The problem here is that the inlet doesn't just collapse, it can partially deform under various vacuum levels and potentially (hopefully not) collapse. Or not. When the silicon gets hot and has a decent vacuum pulled on it, it moves. Maybe a little, maybe not. A hard inlet is consistent under all conditions.

One of the other things you'll also notice, and comes into play in regards to flow/pressure drop is the shape. Nearly all the units out there have a sharp corner. Ours is MUCH more subtle and we grew the diameter in the corner to further reduce turbulence.

Adding intake spacers give some height, but you still have other issues that prevent enlarging a simple tube, plus the power steering pump is in the way. We have that all laser scanned, OEM inlet laser scanned, and so on. We have a whole engine laser scanned actually

Appreciate the feedback!

Am I the only one that cant see the dyno plots referenced in the first page?

15WHP and 19WTQ over the OEM intake is nice, but the real question is how much over the average silicone inlet? Obviously there are lots of variables, but silicone inlet usually claim ~10WHP & ~10WTQ.

I do not doubt your ability to create a high quality product. I just figure it's a large investment and if its going to run 50%-100% higher cost than a silicone inlet, then it needs to perform a good bit better too. I could be wrong. Maybe people will drop the extra cash just to get 'the best' inlet.

Not really worried about the performance cause I know you guys don't mess around but really I'd like to show support towards a super high quality part comming from a killer company. I would choose a killer b part over a perrin part any day!

Thanks for the feedback guys!

On the pic hosting, I'm waiting on a response from nasioc. Something with the img site is wonky and not letting us login. The pics I've posted were from our facebook posts, and it looks like those links may be dynamic. I'll try again...



I agree on the bang-for-the-buck. higher quality units are in the $200-$280 range. Ours being $300 should have better performance. Is that last $20-100 worth the extra 5hp and 8 ft/lbs? Maybe to some. To the Ebay bargain shoppers, our products are not a fit to begin with and I wouldn't say the products are comparable.

Forgot to mention...

We have committed to tooling, CNC programming, and so on. Hope to have some firm dates on availability soon.

Any idea if these will be ready by March for the gr wrx? I'd hate to buy a Cobb and regret it.

Nice. After doing a perrin turbo inlet on my own car yesterday, i can definetly say its not really a begginer job or atleast a job to claim to say its easy. Its a pretty straight forward job in removing and replacing but requires patience, skill, and finnesse. The perrin piece was pretty tight without pulling the manifold, i could only imagine how an actual hard inlet would really fight to get in.

I would imagine that something like this would have to be made i guess more narrow or not as wide. Also how to do plan to get it to attach to the turbo snout? I guess by using couplers? At that point might as well just do a whole silicone inlet.

Isn't the GR WRX OEM inlet different?

All hard inlets use a coupler, but a coupler does not move like an entire silicon unit since it's short and supported on both ends.

Our hard inlet has a larger I.D. because the wall is significantly thinner than the silicone versions. It's also contoured very differently than other units so it slips right into place. Our 90° bend is also not nearly as sharp, providing a smoother flowing bend.

Interested in getting this since I plan on upgrading my fuel system somewhat soon. My tuner suggested the Cobb SF intake to do as well. Will this be compatible with it?

So you mean to tell me this will be easier to install than the Perrin turbo inlet? Will I need a tune to run this if everything else is stock?

Yea it only shares fitment with the 05-09 lgt as far as I know. I'm guessing this will be an sti only deal then? I wasn't sure from the thread what fitments you were going to be offering.

KB,

So have you decided to make a coupler that will fit your inlet and the FP turbos?
My FP inlet collapsed on the track and I’m hesitant to purchase another one just to possibly have it happen again.

I usually put one or even two hose clamps with about an inch and a half between them on the center section of the fp turbo inlets under the runners because they pretty much suck the male chicken and collapse guaranteed
