Im getting bored of my escort cosworths power and am wondering whats the next step to take in upping the bhp but still keeping it nice and driveable.
Heres the spec so far.

Long studded 200 block with 7.9.1 low comp
Nick Waples fully ported head
bd8 exhaust and bd16 inlet cams
403 greys running a gt30 compressor with a 48 exhaust housing on standard manifold.

Its also got 3.9 gearing, its drives great but just runs out of power after it gets over 5k rpm.
Just interested in what you think?
