Woot the boost controller fixed it! 307.9rwkw at about 14psi
Im a happy camper!
Re the GTR motors. Thats great but a 2 litre can make over 400rwkw too. Its not really the same. Think about the power delivery I get boost at 2000rpm, would a 430 rwkw 2.6litre be the same? Im sure there are heaps of other variables making the examples different. Turbo size, rpms, different coolers and piping, exaust systems etc etc etc.
