Anyone have anything available yet. Lost another gasket on Friday and this is getting on my nerves. I've expanded the pipes for a tighter fit. This helps but not a cure. I have two of the soft sbc doughnut gaskets left and can't find any more.

I am interested as well. I posted a query on TDS about 6 months ago and there was innuendo that DI might have something in the works analogous to the one piece up pipes for the Garrett Turbos. Anyone?

so are the H2e OBS and Superduty up pipes all the same? Will OBS pipes work on SD?

Who makes the soft chevy donuts? The Ford donuts are to small and the flange bottoms out, The cheapies from Checker burn out in a few months. I've had Victor Reinz for almost a year and now they're leaking but its still to damn hot to mess with them. Ive got Felpros to try next.

Mine are not leaking, but the turbo has only been on there for about 2000 miles. How long does it usually take for them to start leaking.

This'll be my 4th set in just over two years.

These were in every SBC Felpro set for years. For that application they were too soft and everyone threw them away. I hand found a few old stock singles in a couple NAPA stores. As far as I know they are no longer available. They are thicker and as soft as the factory Ford ones. The heat from pulling take a toll.

IIRC, Hypermax recommends using the oem donuts. I tried the sbc donuts and they failed too (they're too thick and didn't crush correctly). This time I used a plethera of anti-sieze on oem donuts. I also "eye mic'd" my flanges with a straight edge and found one of the clamping flanges was too deep. I hit it with a grinder pretty hard and then refinished them both with a flat file. I also had my up-pipes coated by Jet Hot (when I had my dp, turbo ped, and turbo mid and center sections coated). The few thousandths of coating on the slip end of the up-pipe I hit with a light sandpaper to smooth the wrinkle finish just a bit. Only got 1-2 k miles on it since, but so far so good.
House is right about the "pulling" temps being extra harsh. I might "pull test" my system over the next few months.:gun:

I have used the F17250's with the Hmax kit and they work well. I have a set runnin around here that have been on the truck for almost 4 years and they have seen dozens of burnouts and racing and even multiple engines. Just have to tighten the crap out of them to get them to seal, if they leak at all they will burn up in no time.

The one time that I surface ground the clamps to reduce the depth of the seat and crush the dounuts more they didn't leak. The actual up-pipes just wrinkled up and push the manifolds off of the heads and sheared the rearmost bolt on the driver's side.

After that I was done with the bs pipes with ZERO provision for the hanus expansion/contraction that is unavoidable when you go from 2 or 300 degrees to over 1600 degrees in a few seconds, then right back to 400 or so, only to shoot right back up to 1700.

I now run these.

I'm sure that is what the H-max kit will also turn out like.

Work like a charm. I warped the driver's side flange that holds the bolts to the manifold, but I beleive that I might have overtorqued it a little in conjunction with the 1800 degrees egt and it's got a little curve in it now. I'll cut it off and straighten it out, but they don't F'ing LEAK.

Try 1800 degrees with 40pounds of boost on a 38R with the stock trash. These have been running for around 7 months now I believe. Tough as nails. (Tougher than the manifolds that warped, started falling off of the head on one side and cracked between 3 and 5 on the other)

I've got to give credit where credit is due. Other than the warped flange, they are flawless. Nice job David. (He mutters with great reluctance)

:D

Hey Bean
The F17250 is the silver gasket that's made by Victor Reinz and sold by NAPA right? If you have a source for them you better stock up. It's a discontinued item and none of the stores around here have any old stock. I understand that the Victor Reinz company no longer manufactures and sells to parts supply houses, only direct to manufacturers, at least that's the story I've been told by two different NAPA stores. All the stores around here now carry the Fel-Pro FPG8194 for the SBC gasket.

I used one out of my old stock today. Good enough for a second place at the pulls tonight.
Yes they are discontinued. And the new ones are too hard.

I'm glad you mentioned carquest. I havent been in one of their stores in probably a dozen years and didnt even know where one was. I googled it and found one only 4 miles from here. I went down and they had 2 of the F17250's on the shelf. When I told him about the NAPA Victor Reinz story he said they're full of #### and probably just found a cheaper supplier. Any how, he looked it up on the computer and there are 84 sets here in the local distribution center.
