Twin K27's might spool a tad slower than the GR BB turbo's but will still hit the same peak HP rates, given the same manifold PSI. The torque curve will not be as flat as your tubo's will build manuifold pressure at a slower rate due to spool time, however once at 12psi they will generate the same power as any other turbo at 12psi.
The big difference is twin GT BB turbos could generate 30psi and get htere at a lower rpm, where your turbos might peak out at 15 or 20psi.

Mine were never matched up when callaway did these cars so in the map on this turbos they will bo off the map at 12 psi . But we will see . This car is getting the GT twin BB on it .
