heat soak at 170mph

i reset the secs before the run whilst moving, the peak reading was from being held on boost for as long as i possibly dare before a corner not to be taken at silly speeds approached rather fast!! i glanced at the r+b gauge just before breaking and read the peak data from the secs whilst cruising after the run

you have to consider outlet temp also..... (were these tested in the mag? i havent got it )

mine will be a considerably higher than yours given the smaller turbo being borderline oversped, yours aint anything like the shaft speed or outlet temp a t34 is at that boost/rpm

PS presuming you have a t4 at approx 2 bar held?
