I am curious what is safe for a supercharger Crank and pulley size with an 8 rib? Let say I went with 8" crank pulley size and would a 3.40" diameter pulley be safe for a 350cid Goodwrench Engine?

Just curious and let me know thanks.

 

Anyone, know??

Please let me know thanks.

 

No one, know? I am wondering also if there is an 8" Crank Pulley and 3.75 blower pulley out for sale? What brand and what is the boots?

Please let me know thanks.

 

What type of blower do you have? Is it a Vortech or a Paxton?

 

I was thinking of getting a ATI Procharger D1SC. I was told that they do have a 8" Crank and 3.75" pulley that would fit the charger, but not sure about the belt length. I try finding information if there is a 8" crank and 3.75" pulley out there, but no luck.

Thanks.

 

Try this spreadsheet, calcs blower speed with different pulley combos, dont know who to give credit to, found it on the web some time ago

Thanks, that interesting.

 

Well on my basically stock engine with a 7.65" crank and 4" blower pulley I would get 10psi at 5500RPM, with a 3.4" would end up with around 16PSI depending on pulley slip. This is on a D1SC blower but should give you a idea what to go for.
