AK, you are right I heard Inconel mentioned and do know a little about it but did not know what the pre cups were made out of. I assumed Inconel was what they were without finding out first. This material incidentally is extremely hard and I don'y know if it is machinable?
For many years, Inconel has been used for Formula One and Champ Car exhaust systems. More recently, several Winston Cup racing teams have utilized Inconel for producing ultra-light, high-durability exhaust headers.
Burns Stainless recommends Inconel 625 alloy for exhaust systems due to its...
Inconel by far, is able to withstand far more abuse than any 300 series stainless. Modifying the Inconel cups would be advantagous. In case you didn't know in general, turbos turbine impellers are all made using Inconel. It's melting point starts at 1600°F. In racing turbos pupose built they...
It's just something the Swedes have been doing on the BMW's. They are pretty good improvisers making something work better. Just like o-ringing any engine they need to be custom machined. I understand the physics of the pyramid method and thought it would work well for your level of boost. It's...
They don't remove the original stock ring... The pyramid ring only sticks up slightly and supports the outer portion of the stock ring so it can't be pushed back from boost. The pyramid rings are custom made per application they aren't ready made.
Of course it would work with cast iron heads. These are not like a fire ring but rather a dam to reinforce the stock gasket. This way there is no need to groove the heads or deal with the water jackets leaking with the copper gasket.
I been thinking of the o-ring issue. The Swedes have been machining the BMW blocks to accept a large o-ring that has a pyramid shape and it only fits into the block. Nothing is done to the head. This ring provides a structural support for the stock head gasket that creates a dam and doesn't...
Thanks guys,
I found a crimped wire by one of the dually fender mounting nuts. I must have not paid attention to what I was doing when I widened the fenders for the 22"s. :mad2::mad2::nonod:
I am trying to figure this thing out. I checked the bulbs and they are all fresh. But the running lights including dash lights keep blowing the fuse at random. It will work fine for a few days and then it blows the fuse. It is intermittent??? Any ideas?
Yes it looks like a bolt that threads into the hub and that is drilled and tapped and another bolt but with a bearing on the end. The compressor shaft is tapered with a key way. Snap On sells a tool set that has a set that fits different hubs. Most auto parts stores can get the pullers from...
