What pulley to use
What pulley setup should I go with as I am sending my snout over to a person who modifies my lsa 1.9 twinscrew blower. Wanting 800+WHP on e85 what should I run for the top and bottom? How much psi would I be running with my 427 lsa block ? Supporting mods would be a blower cam headers ported blower and snout my custom 5 inch CAI stock lsa heads for now. 11:1 compression. Sorry idk how pulleys work with a blower first time
thanks
thanks

I don't know the blower sizes on those, but id be surprised if you can make 800 with a 1.9 blower. I pretty well maxed out my eforce, which is a 2300, and made 780.

some tuners and weapon x thinks it’s posisble been seeing ly6 and ls1 pushing 620-650 on pump gas with just a cam figured everything ported and pulley it with e85 would get close to 800whp on e with a 7liter or maybe 700 on 91? Or close to 680 I’d be happy with that then like 750whp on E

Olson Kustom Works only has a 2.45 upper pulley, they biggest lower I know of in vette spacing is 8.350. I would call ATI or IW to see what they can do, other wise you might just have to do the normal 15 OD INW-8502 from Innovators West.
Looks like a lot of places dont recommend going much over 23k rpm on the LSA blower. so with the 8.350 IW crank and the 2.45 upper you are at 23,800. (8.35/2.45 = 3.4) (3.4x7000 rpm = 23,800)
