Twin 61mm on stock cube ls6?

Tried searching but couldn't find where they tend to spool up at. Any experiences with them and details on your setup would be much apprecatiated!

Thanks!

humm.... for stock displacement I think 0.68's would be better, depending on your ultimate power goal...

I agree with Tiago, run .68 hot sides if you're concerned about spool. My guesstimate is that they could reach 20psi by 4,500 or sooner if ball bearing. Assuming p-trim wheels those turbos can support 1000+rwhp.

I would say full spool would be in the range of 3800-4500rpm.
I have full spool at about 3500rpm,but I have a little more cube's!
You will enjoy it. Daily driving will be normal until you hammer the gas pedal.

Define "full boost" The same combination running 5psi peak will reach "full boost" much faster than the same combination at 25psi.

i would say 25psi. it seems that this is the amount of psi to flow air to make 900 crank hp, no?

I agree with the others and go with the .68 if spool is your concern. I have a 408ci and I hit full boost in the 3500rpm range with .82's....

The bottom line is keep the 61mm turbos and just change the A/R. You will be fine..
