Prototype turbo inlet pipe

[Sourskittle]

No... I actually do think its possible Europe got a bigger TIP... Or that Puma speed felt it irrelevant to measure the stock because its so painfully obvious.

Really that being a 90* bend with an inside dia of 35mm super tops it off. Its very obviously the biggest restriction in the intake system. From the filter to the turbo, its BY FAR the smallest and most restrictive part of the intake.

I honestly don't think its going to take dyno numbers to sell these.

If you held them both in your hand as I have.... You'd laugh, honestly. A G.I. Action figure could BARELY fit in it, lol.

Also... Please no one edit Dyno's post. 1 year from now... I'd like to bring them back up

And he is entitled to his opinion. We agree to disagree

Bolt it on, bolt it on. I'm getting older here......

if I had a manifold and DP it would be in the tuning stages but alas I must wait my turn...

I believe the bend isn't a huge issue. The inner diameter of the tubing is less than the overall bend radius so it's not horrible.

I wish most smaller shops had the ability to fabricate a fully smooth size increase from turbo outlet it the end of the fitting though...

 

[Sourskittle]

Iso a big issue is keeping the stock flange. The bolts are only so far apart. If the piping is too big, directly off the flange, you will never be able to get bolts into the flange to bolt it on.

Also. We are not going to except any money until the 5 are built and in hand. So when they are done, it won't be "3 weeks out", it will be "pay and it will ship tomorrow". The builder is just old school and doesn't want to take anything until its done.

But we can keep the list and I'll let everyone know when they are finished and ready to ship.

The stock turbo inlet is about

that big. Lol. Sorry. Didn't have the mic on me that day I guess, lol.

But is the compressor inlet size is the real limitation, then our stock air box and all the plumbing is incredibly over sized and should never be replaced.

SS - Thanks for measuring this, looks like 1" 3/8" which comes out to 34.925mm, which is super close to your micrometer measurement of the outlet of the stock pipe (35.11). Confirms what razor said.

I am interested, but as of now im puting in the ot! (Funding trip to utah!) But if this is still available in a few weeks im down!

 

[Sourskittle]

Its going to take 2-3 weeks for the first 5 to be built, so you have time. Just two are already spoken for

Any concern with turbulance or flow issues when the air arrives at the turbo inlet? The stock pipe gradually works it way down to the 38mm, which would smooth out the air flow and increase the speed as it enters the turbine. I am thinking of a column of air hitting a flat surface around the blade and needing to find a way into the turbine against the incoming flow. It seems to me that the inlet pipe where it meets the turbo needs to be the same size as the turbo inlet. This would create a velocity stack type design. It has been a very long time since I have done any fluid work, but it seems like this would be something to look at. I might be totally off base, but just my thoughts from looking at the pictures. I haven't seen the parts in person enough to make a better judgement.

I am also kind of shocked at how small the turbo inlet is. I knew it was going to be huge, but wow, it is smaller than I would have ever expected.

Yes, a step would create turbulence. So something like this works well for a larger compressor wheel and inlet, like the turbo Skittle is testing, which is why he is making this inlet pipe. I also think it's great that he is taking the initiative to make this stuff.

Personally I think it would actually be detrimental for a non modified stock turbo because of said turbulence from a step. It's the same concept as port matching intake and exhaust ports on a cylinder head.

I am also kind of shocked at how small the turbo inlet is. I knew it was going to be huge, but wow, it is smaller than I would have ever expected.

I've been saying this for a good long time. The stock turbo is S M A L L. It's actually laughable and surprising the car even makes the power it does. This is also why I chuckle a little bit at upgraded intakes and exhausts. If you think the compressor wheel is small, you should look at the exhaust turbine size for a real good laugh.

I haven't dug into the car enough to look at much of it, and haven't paid enough attention to the 1.6L cutaways at the auto shows. Sometimes just seeing a tape measure across the inlet really makes you realize the size!

The quality and look of the inlet pipe is awesome, and great work on taking the steps to bring it to production. For those of us with stock turbo housings, the inlet tube being matched to the inlet on the turbo is the best option. A 3 bolt flange connected to a 38mm velocity stack connected to a pipe that will bridge the gap between the velocity stack and intake tubing would be money for the stock turbo.

17mm wrench

I've heard the Turbine is small

 

[razorlab]

So cute.

I was just wondering how easy or hard this is to install. Do I need to remove the turbo, or can I install this simply by removing the stock turbo inlet from it's current place?

'scribed...

As soon as I get mine I will tell you how it feels to my butt.
To me that is the only performance gauge I care about.

Once this inlet pipe is installed, anyone else that wants to feel my butt is welcome to do so.

You don't have to pull the turbo. There is a cover that has to come off ( two flat head screws ) and the intake tube its self of course. Its 3 5/16 screws and an air hose

 

[D1JL]

Its 3 5/16 screws and an air hose

On this car, that would be 8mm.

Great! Sounds easy enough. How do I sign up for one?

 

[Sourskittle]

Just quote the list and i'll let you asap when they are finished and ready to be shipped
