does anybody know what size pulsar gtir throttle bodies are? and what power people run through them before they change to another system (if they do)?

any help appreciated

 

The butterflies are 45mm'ish in diameter each.

They tend to be swapped for a big single TB to make it easier to run map based management rather than maf. Not sure what the max power is you can run with them but 450hp is certainly possible.

 

If they 45mm then the limit is almost untouchable on a turbo application, as throttle size is less important than with n/a.

As Jamz said, its harder to map with TBs tho so people change em as on turbo cars TBs dont make a huge difference, just slightly better throttle responce.
