**** 545 on 3psi....you turn up the boost to around 8 psi, i would think you would be at least 650rwhp. as long as the blower would hold up to it. in your case i think a 122 would be better on a 403ci motor than the 1900. it i had more than 400ci i would go with a 122. i think im going to put the crank pulley on this week and the meth and see what it turns out. i hope it around 600hp - 600tq. if so i might put a 100 shot on just for the hell of it.

 

i am very interested in this upgrade and i cant send my 112 to you because of the distance....is there anyway that i can buy the 122 head unit and install it my self..
i see there is only 6 bolts holding the top part (rotor housing) to the lower part(intercooler housing).. is this just a simple top part swap??? if not then what do i have to order?? complete box 1??

 

Does anybody know if I can upgrade on the SSR 112 to a 122?Where can I purchase an 8" crank pulley for the SSR?

 

The only guy that has the SSR MP122 Set up is Joe @ Left Coast 32.

 

05crew, don't think the 122 will give 8psi without overspinning it! marine02ss, try ASP ask for Lee.

 

Joe is pumping 10 psi into a 427

 

from what i have read and talk to joe at left coast the 122 will give you 8psi and some if you want, blownchevy can help you with this!

 

talk to Brian and just got done talking to Joe these guys are really cool and very helpful!!

 

I searched but couldn't find any info...

Are there any threads that discuss what boost levels can be made with what diameter pulleys on the 122HH? Need to know what pulley to have installed with the upgrade...

 

So...having paid considerably more for my Box 1 kit a while back, what will I need to spend to make my old MP112HH work again? As I didn't do the work myself, I'm not sure what came with Box this or upgrade that...R/
