Hurricane turbo intake upgrade

[74Nitro]

Update:
Preliminary Info;
A. The crossover tube is subject to substantial heat from engine, turbo, and underhood heat. Actual overall length does vary as temps increase or decrease.
B. The turbo is mounted on a rigid cross brace. Although mounted on that brace, the extension of the inlet flange (towards the pto side) does vary as temperature fluctuates.
C. A+B together causes fluctuation in distance between turbo and air box or CAI. (In this case, the CAI was a solid aluminum housing mounted to the belt guard so there is a fixed location of where the crossover tube located on that end).
D. While running, especially at high boost levels, there is substantial suction created in the crossover tube by the turbo.
D. Identification of plastic used to 3D print the inlet tube is needed to establish specific melting point/tolerance to heat. What temp causes it to become flexible or elastic enough such that turbo suction along with decreasing overall mounted distance would cause it to collapse on itself?
As previously stated, I will (hopefully) chatting with Dave Marshall tomorrow to gather more info.

There is plenty of heat under the hood, but while running, there is always cold air being sucked through it. The compressed air is the warm side which can get up to 120f.
No need to over-think it. I agree with twiztid. It's just a case of the wrong material(poor quality) being used for the application.
The rubber on the stock piece will also act as an insulation barrier preventing heat transfer from the aluminum of the turbo to the plastic.

idk. Mine seems to be holding up fine. Aside from the initial problem I had clearancing the coolant line everything looks good and sled had been running great. I’ll just keep an eye on it

Internal and external temps could be vastly different.

Mine mine has deformed a bit causing the hose clamp connection to become loose, twice. The indentation to clear the steering post also sagged a little too. I was able to take the heat gun to it and massage it back into place, but i have a feeling I may just order a new intake duct now that ive seen others with the problem...

I've only had mine on the sled for 300 miles, if mine were to collapse like the one Turboflash posted I could be in for a Helicotper ride to get the sled out of the backcountry in the mountains.

Stat Holiday in Canada today so you maynot be successful

You are correct. In USA it's President's Day; in Canada it's Family Day. Holiday.

It's really good to know that quality was sacrificed and this could have worked had it been built better. Thanks...

Wouldn't leave you stranded if you have a screwdtiver. Just take it off temporarily.

I have no idea how many of these were sold, I know how many I sold (which I sold all of the ones that @Turboflash installed) and 1 has a failure that we know of. Some of you are crying the sky is falling, for f sakes, it was 1 failure out of 500 or 1000 (I don't have an actual number) and throwing Dave under the bus. Sometimes #*$&@ just breaks, it's not a part that's going to ruin your weekend, you could literally trail ride at 60-70 mph and never know something was wrong!! I had one on an asphalt sled all summer long running 30 lbs of boost in 100 degree heat and I looked at it this morning and it's perfectly fine. This sled never gets the hood opened up because it has a radiator, fan, bilge pump mounted on the back of the tunnel to cool the sled, it's driven to the starting line, down the track, and back to the pits every time all summer long.

Relax a little, I sent @Turboflash another intake tube next day to him at no charge so their trip isn't compromised. Take your undies off and untwist them so you can enjoy the rest of the week!

Well said Alan!

 

[Turboflash]

A Huge "thank you" to Allen for sending a new one to get the sled back in service.
He had to drive a ways from his shop to get to a Fed Ex location. He even paid for the shipping!!! Whi else would do that?! Great guy!!!

Well with it being below the secondary intercooler it would be more than a screw driver, but yes hot underhood air is still better than no air at all.

Found another one today. Sagged/partially melted from heat.

What does Hurricane say about this???

Crap Gotta dig into mine and recheck after my last trip. Wonder if there is a more heat resistant material he could print them out of?
