At the end of last year I ran the 1/4 at Darlington. First full pass I didn't expect it to run the mph it did and hit the rev limiter and for some reason it caused a huge backfire. After this, the supercharger had a different whine. I made another pass and drove it around a little when I got home and then dropped the oil in it. Nothing was on the magnetic drain plug, so I kept gettinn it. I drove it on the street and raced it several times up until last Saturday. I stood in it, and on the coast down, the car picked up a vibration around 1800 rpm's. Last time it did this, it slung the rear bearing out of the alternator. Not so lucky this time. Knocked the blower belt off and it didn't sound good turning by hand. The next day after it cooled off it sounded worse. Dropped the oil and it looks like bearing material that has spalled off of a race. I guess it got a thrust bearing as the impeller will move back and forth a little bit. From what I gather it's around $600 for a rebuild, so I'm thinking I can finish the turbo installation for about the same money, so it's just a good reason pushing me that way. I could probably do it myself, but from what I gather online, Procharger used some propriatary parts that you just can't buy. We'll see what happens. Clay

That sucks but maybe it time for a change to the turbo. For a street car I think the tubo is the best way to go.

Are you looking for a bigger head? There isn't a real advantage to switching over to a turbo once you have a centripetal up and running (well there is in the sense that the turbo doesn't get it's power from a belt), but in terms of economics I would stay with the blower.

Everybody needs at least one......I have a few reasons for making the switch. The head unit is big enough to support any plans I have in the future (rated to support 1050 h.p.). However as I have posted, the powerstroke intercooler isn't and I've been running on racing fuel with no intercooler at the track. So I would have to get a different larger intercooler. Another reason is camshaft requirements. I like sneaky fast and the Procharger with the camshaft that's in it now is impossible to be sneaky with. Turbo camshaft durations should be much lower and smoother idleing. Also turbo's will make the exhaust note quieter which is also the direction I want. My goal is to drive to Darlington (about 1.5 hr. drive) with slicks in the back, put them on, run a 8.99, put the street tires back on and drive home. It's a stretch to do this on pump gas at my weight, but I like to have a goal that's just a little bit out there. I want to be that car that drives into the track and nobody pays any attention to, then after a pass everybody looks up and says " holy sh&t, that car ran a what!!!!!" Very Happy . Clay
