guys, here is some good info. Vortech is working on a sprag setup on their v20 and v28 blowers. Although not useful for us at the current time, I'm sure that the technology will trickle down at some point. I just got off the phone with a vortech tech and he said that the sprag on theirs is going to be built into the blower transmission. Perhaps once they get this done, then they can make a blower pulley with a sprag for us. Here is the article out of this months race pages magazine:

Enjoy!

They are using a similar bearing to the some that is used in the crown vic police alternator pulley. I had one apart and its a needle bearing/one way style. I would really hate to have to spend money on a new blower and brackets.

can these bearings be easily bought? Can we make one of these things? Are there any links you know of? It's been a while since I took a look at this stuff.

Yeah, I'd hate to have to buy another head unit being that I have a ysi with less than 2000 miles on it. The v20 series does look awesome though. That v28 123 is insane. Similar to a procharger f3

The sprag alternator pulley is a one piece with the pulley make by nsk. i had one apart. They don't press apart.

Old thread but new interest on my part.....what ever became of this?

Rokka

Old indeed, but still looking for that sprag.

Can anybody sell me just the sprag for the pulley or tell me where I can order one? I havent found anything to fit yet.

I have D1 and want to use 34 teeth.
So the outer diameter have to be less than 2.5 inches.

Rokka

I still dont have that sprag.
Can anybody give me advice or help me to get one?

qwiketz

I did a ton of research but never found one small enough to work with our setups. I even called a customer of mine that specialized in bearings. Anyone else know anything about this or know of anyone making one?

btw, I posted on ls1tech which gets more traffic these days.

Ok, thanks!
Maybe I start doing it (design and fabricate) here in Finland.
But it takes time and effort to find something to start with.

Hi all i am new to this forum but really interested in what your doing with this sprag setup on the blower pulley. Wondering if this can be adapted for a 8 rib serpentine belt. Working on custom build 1972 panterra and space is of a premium. I am using a F1A-94 Procharger and need a 3" 8 rib serpentine pulley.
