I have an s5 turbo motor that was just rebuilt and am running a lt-10s with 550s and 1680s. the motor has not seen any load yet and I am going to street tune it this week with a wideband. As of right now I am deciding on/saving up for a turbo. I have blocked off all turbo lines and am running a header to 3'' exhaust. I probably won't have a turbo for 2 months or so. Is it possible to get it drivable somewhat, with a smooth transition to the secondaries without boost? Possibly set the staging at 4000 rpm and 5hg? any suggestions??

 

from what i know a smooth transition from 550 to 1680 is dificult but can be done in matrix mode.

 

Dosnt need matrix mode.

Switch them on at 1320 rpm and 03HG.


4000rpm is too late.

 

thats opposite from what I thought, why activate them earlier than on a turbo?

 

i mean NA

 

turbo or n/a It dosnt matter.

To get a smooth transition you have to do it somewere were the 550cc is going to be able to match the 1700 and thats not going to happen in heavy load and high rpm.
