I am wondering if anyone can explain something to me? If you were to upgrade your turbos to the BNR stage 3 twin turbos or any bigger twins, can you run them sequentially? if you can, is it better than non, and why? Would you expect same power band(low to high rpms) as the stockers with more juice, or what? I am really trying to get this straight.

 

bump, bump, bump

 

someone has to know and can explain it? please?

 

Sequiential turbos operate from a flapper door in the exhaust that directs gasses into the second turbo at a preset boost level. This in itself is a restriction, and they tend to fail pretty often. Thats why most people run them "true twin" or switch to a larger single.
