i am looking into getting a bbk full. But I have some questions. I am sure I am going to do a bbk turbo on my car but. How much more whp does a turbo make over the stock turbo. I under stand the tuning is a big part i will have cbrd do the tunning. I looked allot and i don't really see the same setup with just the add of a new turbo. I do under stand that you may need injectors and what not. So i mean say 20 psi stock turbo and 20 psi on a bbk what would the whp differences be. I did a search and did not find the same psi for bass line numbers.

Read this thread.
BBK turbo is a very good choice! Lots of info here

 

Well the biggest gains won't be had from swapping turbos and running the same boost. You'll want to run more boost on the BBK to get the most out of it.

 

nobody running the bbk would have their turbo tuned to 20psi. look through the dyno results thread as thats the only place youre going to see anything back to back.

as for my experience, my boost controller for my first run was only at 20psi and the car did somewhere in the neighborhood of 300whp. at 25psi and fully tuned, it did 370.

 

you just answered my question. I could not ask for anything better. I searched for 1 hr on here and found nothing like that.

Thanks man

Yes i know that i just wanted a base line that all

 

at 23psi on a clients car, only thing changed was a ported manifold and the BBK from stock evo 8 turbo, we picked up 67whp and about 30 wtq

Get it right Chad, it was +76hp and +38tq!!

Don't short me now buddy.

 

Ya, that's a very well written thread comparing all turbos on the same car with the same mods and same boost.
Good luck!
