ok, i have a small turbo(t04 60mm), with a 1.00 a/r split pulse at the moment and full spool is around 4000rpm.
i also have a 1.32 a/r that i wouldnt mind trying out, but was wondering if anyone knows how to work out at what rpm would i have spool with that housing compared to the 1.00 a/r?
I understand that ill get more lag, but also i should get more top end, correct?
Just trying to figure out if its worth trying.
i would try it as long as i get full boost before ~4500-4700rpm.

If anyone has any way of figuring this out, please let me know.
cheers.

I think you answered most your questions. But the only way to know is to try it. I doubt your full boost will be off that much. Maybe 200-400 off of what you have now.
