What boost at what revs


dude

Recommended Posts

Must be an auto as it's an Aero.

 

I'm getting maximum boost as the second turbo comes in. I've got a full CW decat and a Hiper with one of Chris's restrictor rings in place. I generally hit 1.1 - 1.2 unless I turn the boost controller on.

 

Before fitting the restrictor ring, I would hit anything between 1.3 to 1.6!:eek:

Could not see that detail on screen Matt, you have a better memory than me.:stupid:

 

I have virtually the same set up as Matt, but no boost controller, a 3” HKS cat replacement with CW pipe and restrictor. I can get my max of 1.1 to 1.2 in any gear(auto) on second turbo, not sure about revs, I am generally looking down the road with peripheral focus on EGT and Boost pod gauges.

 

From memory I think it is probably from 4200 - 4500 rpm onwards. I will go and check later, all in the interests of research of course.
