I currently have the 2.95" pulley but I'm not sure if that's the standard pulley w/ the kit or not. What boost is this pulley supposed to make on a stock motor (it's a p600b btw)?

Where can I buy other pulleys (it's an 8 rib setup)?

Do any of you guys have some laying around that you'd like to get rid of? I need a few to play around w/ on the dyno.

Any help will be greatly appreciated.

Thanks!

 

I got my pulley from ATI (1-913-338-2886). I am also running a P600B, but with a 2.55" pulley. The 2.55" is giving me 12#, the 2.75" was good to about 9#. The 2.95" is good for about 6#, and if you want to go higher you should really run an innercooler if you are not already. If you choose to change the pulley yourself, I recommend using locktite on the bolt - it WILL back out - cost me alittle over $500 for new bearings and new pulley from ATI after the bolt came out. Hope this helps - good luck

 

Thanks man.

How much did they hit you for the 2.55"?

 

I can't find the receipt (from when ATI replaced the pulley and bearings and inspected the charger for me), but as I remember, the 8 rib charger pulley was $150-200. Also, the tensioner pullies are $90-100 each - not cheap!!

 

Have you also considered reichard racing? Jimmy there makes awesome pullies. Just a thought.

 

I would contact ASP racing. They will make you any size pulley you want.

 

I have the 15# pulley for the p600b if you want it. I sold the supercharger a few months ago but still have this pulley. It has maybe 5000 miles on it. I did'nt see 15# though, I only saw about 12-13. Let me know if you want it.

 

SD concept engineering has great pulleys and use better bearing than stock ATI bearings.

 

I could have sworn that when you buy a pulley it does not come with a bearing.

 

How much would you want for it shipped to 37620. Also did you run that pulley on pump gas and what was your timing set at. Also what was the compression on the motor?

 

I bought a replacement pulley from them because the bearings were shot in my stock one. (froze up and broke the blower belt.)

They sent me a new tensioner with the sealed bearings all hooked up. I don't remember what I paid but I think it was $80............but I guess we could be talking about the "other pulley"

 

The 15# pulley krazwag is talikng about is the 2.55" pulley and gives about 12#. Seems all of these pullies from ATI make about 2-3# boost less than advertised. The bearings are in the tensioner pullies, not the pulley on the charger, those bearings are in the charger itself on the shaft.

 

thats fine. I bought the ati 2.75 pulley "12lb" but I only see 9 and I was planning on up grading.

 

Blownred...hey man make your own post!

You got a pm krazwag.

Thanks everyone.

 

Never got the pm. I was runnig pump gas with a crane cams boost senitive timing controler with 9.1 comp. Never had any problems. As far as being for sale Lt1homer has first dibs since its his post but if he dos'nt want it then whoever else wants it just let me know. I still have the orginal box they sent it to me in but can't locate the reciept. I'am almost positive it was around $60-$70 dollars. Oviously I'd want something less than that.
