Have you bothered looking in the RB25 dyno section or doing a search of SAU?
At a guess it will be relatively late making boost and probably making full boost later than 4000rpm. The 76mm comp will probably max out around to 300-320rwkw pump fuel and 350rwkw for the 82mm compressors??
I would stop and have a good think about whether it is worth the effort fitting either of those turbos.
$100,000 less to spend on things he doesn't already have.....
Mansion in the UK....nope
Porsche....nope
There must be something he doesn't have (no jokes about the missus please).
Jones is the pick IMO due to the sun being behind your back and the ability to see the run into turn 1. Brabham has the sun in your eyes and you only see the cars when they arrive at turn 1.
Why? Have a look at the bottom of the 040 pump and have a look at the bottom of an R33 fuel tank. Nestling a sock on the bottom of the tank guarantees no pick up issues just like Nissan did it. An 040 mounted shy of the bottom can be a problem. Certainly plenty of guys have mounted them successfully without issues but there are quite a few SAU'ers who have had issues on low tanks.
As long as the sock is on the bottom they are fine.
Given the crop of newer style pumps then there is little need to use large diameter pumps like the 040/044/984 but it simply isn't true to say they are dangerous.
The slow Finn couldn't keep it up but that is no surprise due to a lack of familiarity and driving time.
Hard to believe but apparently Button wasn't happy with the balance or grip....again/still??
It will fit the RS4S and I can confirm that the NVH isn't affected in any noticeable way.
Yes, they wear, so do the bushed versions....
ps. the Hardrace ones are much more sturdy than the other rosejointed arms you linked from JJ.
