I have a 2.5 fully forged motor,want 500bhp or as near as dam it,thinking 321v or s206 ? anyone running any of the above on a 2.5 ?

 

500 - nice number

 

lol,i thought the same

 

Aren't the Scoobyclinic turbo's making that figure quite easily? I'm sure the s206 is developed more for a 2.1ltr.

 

Quite right although there is also a 2.5 version available called the S215B.
It features a cutback turbine wheel to open up the back end and makes it much better suited to 2.35 and 2.5 motors.
We've used the Evo version to great effect seeing over 530bhp on 99 octane pump fuel.
This one was on a 2.3 stroked Evo with Kelford cams, 2 bar midrange 1.7 bar top end.

 

The SC46 is a popular choice on 2.5's (im running one and cant fault it).

It probably wont see north of 500 till you put some meths in it, but it spools really well on a 2.5.
