Boost Amount Per Pulley Size?

[TYSHO]

Would anyone happen to know what the SS pulley sizes were for the given kit of either 9psi, 12psi, and 15psi?

9psi = Pulley Size Here
12psi = Pulley Size Here
15psi = Pulley Size Here

Any other sizes and given psi would also be appreciated, basically what you run and what psi you're getting.

I searched and searched but came up with nothing.

you will also need to include mods and the specific S/C you are running

I'm just looking at what SS offered in their kits per given PSI, and what others are running[if different from SS diameters] and the PSI they're getting.

3.48 was around 12 psi from SS on my SS S trim setup and boost pipe
3.25 was 15 psi on my SS S trim setup and boost pipe
3.12 was somethere around 17 or 18 psi on my SS S trim setup and boost pipe

and...
2.87 was 2x psi

I think you sould sell me your s/c car since you have that Viper now.

I think Vadim changed the sizes over the years .... but around the year 2000 the 9 psi kit had a 3.48" , the 12 psi kit had a 3.33", and if you requested it you could get a 3.125" for I guess a "15 psi kit". My 3.33" would produce 14 psi boost at around 7800 rpm. The 3.125" would produce 17 psi .. and of course these are non-intercooler figures.

Thanks for the replies, guys!

On a T-trim boosting a 3.0L with EH, BBB's, ported heads, and cams, I got 11 PSI with a 3.6" pulley (stock motor would probably see 12-13 PSI). I got 381whp with this pulley slipping at 10 PSI (loose belt and original Vortech pulley - Before the Reichard).

My next pulley will be a 3.5" Reichard on a 9.5:1 compresssion, 3.2L with all of the above mods. My guess is 13-14 PSI on that setup, but could be more like 12-13 PSI given the extra displacement and slightly lower compression. I'm hoping for 450whp on street gas, we'll see.

On a completely stock long block 3.0L, Pat runs a 3.33" on an S-trim for 15 PSI. He got a best of 445whp running this setup.
