Not sure its been shown before with a graph so here it is,

The main point of concern from a few discussions on here was the GT28'rs being bigger and maybe experiencing more lag, not at all it seems, they spool up much quicker and hit full boost 600rpm earlier in the rev range. It makes more torque and power right through the revs, great turbos!

I found it stuffed down behind the passenger seat smile lol

Yeah Gadgie, between 3-4k rpm the car feels like its pulling a wheelie,

Never really looked into the difference till now but the best bit has to be still having 600bhp at 7000rpm where the T28's have tailed off down to 525bhp by that point, 75bhp more at top end! makes such a difference.

Oh yes. smile

Nice one Graham! Spool up looks pretty much like mine from memory (1 bar of boost at just over 3k) - these GT28's certainly work well!
