What do you reckon these turbochargers could flow (two working on a 3.8 V6) on 100 octane V-Power- do you think they could get anywhere near 690bhp? If not what do you think would be a realistic max?

Turbine Blade no. 11

Compressor Blade no. 6 + 6

Turbine Rotor Size 53mm / 48mm

Compressor Rotor Size 60mm / 46.5mm

Max. Turbine Speed 165000 rpm

Wastegate Open Press. 78 kPa

A/R Ratio 15

Compressor seal material Synthetic mica + Teflon

Yes Jamie, new GTR. I'm just interested if the conspiracy theorists can support a claim that the GTR had 692bhp on Top Gear & Nurburgring. Petty yet quite interesting (to me).

 

Gav, I've no idea where to find compressor maps for these IHI's
