So I have a S480 in a compound twins setup w/ V-clamp. 62/14 on top.

I'm seeing 30psi from the bottom turbo and 60psi overall. How much is optimal to stay within the effeciency range of the s480? 35psi? 40psi? what is the max?

Thanks!

 

id say right around 0-40 psi


reallly dont know bud sorry

 

geeezus. .

wondering if someone has a map or some expertise.

 

I ahve a map to the shop.

No one has maps for these things. It seems that 32-34 psi is about max before you start seeing drive pressure issues anyway.

Are you going bigger on the secondary? Something like a 64/71-14?

for now i'm not. i want to see what is capable with what i got....


someone has to know what these s480's should be running at for sure.

 

What do you think you are capable of putting down as of right now?

 

Call Nate at MPI he builds 62/s480 twins right?

 

Heres your boost map

 

Good job Red.

 

thanks brah!

Any chance you have a map without the "race cover"?

My goal is to figure out what to set my overall boost of the bottom turbo at. Is 45psi safe? Is 50psi safe? Where am I going to get the biggest bang for psi?

Thanks again!
