T76 Turbo. Stock LS1
I have a Large Garrett T6 flange with a 1.30 turbine housing and a 76mm compressor side turbo and a stock cubed LS1. I am going to run it at about 5psi and wondering if anyone has any idea about what rpm's I will see full boost at? I don't know how to figure it out and have yet put it on the car. I never did understand those compressor maps. Thanks for any and all help!

Thanks for all the replys. I originally bought it for a 434ci but dont have that any longer. So the .96 housing will help alot on this monstor? If not then....well. I have a rebuilt turbo for sale.. Anyone interested? Or trade for some smaller turbos.

A T76 will not reach 20-30psi on a good flowing LS1. Hell a S88 will make around 28-29psi max on a built LS1. The biggest baddest T4 76mm unit will probably still only make around 20psi max.
