*** Intercooler Hoses Popping off ***
To all of you guys who are running high horsepower 993 TTs.. What do you guys do about the intercooler hoses popping off??
I have gone through 3 sets of the hard rubber hoses with the orange ends. Last night, I made a high boost pass and as I lifted off the accelerator I heard the flutter. I knew right away what it was; passenger side intercooler hose had the ends torn off and oil all over the place.
I am getting tired of replacing these things. Anyone got any ideas?
I can't understand why the intercooler input pipes dont have any recessed grooves on them to hold the hose in place where the clamp goes over it. An engineer fell asleep when they designed these things.
Also, does anyone know if there is a hard-pipe kit for our cars?
Thanks in advance.

How much boost are you running?
I just had my first one blow last week. It didn't actually break, but just kind of popped off and the orange end was a bit mangled. I purchased a new hose clamp from a generic auto shop to get me home. I ended up running a complete DE at Buttonwillow with it Monday as the new one did not come in in time!
It was my first one in 15,000 miles.
I run an FVD ecu but I don't know what the boost is. (I was told it is not too much over stock though.)

I am going to talk to a friend of mine to see what it would cost to manufacture a hardpipe kit for the 993TT. I think there would be a market for it.

Been there & done that! Hose blew off at the right side upper IC connection three times after very high speed runs. The solution? Breeze"constant torque" clamps fixed the problem. I have about 75 runs above 200 mph on the present set without incident! Breeze has a web site with data. The clamps may be purchased from most truck repair centers. I bought ten sets and passed tem out to my open road racing friends. Less than ten bucks for a pair. New hose and Breeze clamps should fix the problem but you may have fried the turbos because the engne quits when the hose comes off and the turbos do not cool down properly. At least that was my experience.

Roland,
Thanks for the info. Here's the site for the terminally lazy:

Scott: lets order a couple of sets? This sounds like a no-brainer that even a doofus can and should do!

I'm in for 2 complete sets (I always want spares). So anyone know which ones we need?
I am assuming Victor that you also have K24s or some such upgrade. I found that when I went to the new turbos, the bumps on the outside of the turbo housing no longer meshed with turbo tube. My old K16s has 2 bumps and the outside of the housing and the inside of the mating surface of the turbo tube had a bump. The turbo tube when pushed down all the way on the K16s meant that the bump from the tube fit in between the two bumps from the housing. Throw on a screw clamp and your fine. On the K24s, there was only one bump on the turbo housing and at the same point as the bump on inside of the tube. What I found was that when I tighted the clamp that the turbo tube tended to try and push off the turbo. Solution: I cut the bump off the inside of the tube. Now it seems fine...
Wish I had a picture so I didn't have to try and explain poorly with 1000 words.

I'm thinking that the advantage in a large order is simply saving the shipping costs. Unless there is a quantity discount, it may be better to have to Nor Cal guys organize their own purchase, and the So Cal guys do their own. Then there would be no "reshipping" expenses.
Roland... what size, what torque? Got a part number?

Yup. I have the K24S Race Trim turbos (ceramic impellers, ported internals, etc). The hoses have never come off the turbo side. They always pop off at the intercooler. Its on the intercooler that I wish there were some ridges.
Right now the intercooler has 2 smooth pipes that bend downward. When you slide the rubber hose onto the end of the intercooler there is no ridge to hold it in place, so it will slide right back off very easily.
I would have assumed that if they machined ridges/grooves into the intercooler itself sized the width of the clamp that it would help to hold the hose on there when it was clamped down. Right now, under boost, they just slide right off.
It also doesnt help that our engines blow oil through the intercooler, so god help you if a little bit of oil finds its way onto that pipe. The hose will definitely slide off at that point.
These constant torque clamps might be the ticket. I am going to see Al tonight so I'll have a chat with him to see what he runs on his car.

I had the same experience as Ruf Racer, after a Mid Ohio DE. No engine mods. I might try the Breeze clamps. Does anyone happen to know the correct part #? My car is at the race shop right now, so I can't measure anything.

We use Breeze model CT300 clamp. Changed the IC clamps only! I always lost the upper right side clamp. My wife bought twenty five sets from a truck repair center. I think they were about five bucks each! Believe me they do work. We torque to approximately 6"/lb! After cleaning the hose carefully install and then locate the clamp close to the "bump" on the IC pipe.

Huh? What? Darn it Steve you woke me up.
Where is the nearest big truck repair store? I think there is one off of the 101 in Oxnard, but I can't get by there today. I'll see if I can call them tomorrow.
Anir: By the way, because of your description of losing your brakes the other week at the track, I stopped by my tech and had him take a look at my brakes. I ended up getting new pads because of it before I went to Buttonwillow. Thanks for the heads up.
