the 181 should generate 18.3psi with stock intake - add 0.7 for DCAI
the 62 on 155mm crank should generate 19.0psi with stock air - add 0.7 for DCAI
you will need a
PSK for slip +
Supercooler for cooling +
SL55 fuel pump +
tune
(and as others have said - maybe not - but to be safe
looped rail+
550cc injectors from TTM) however stock are already 480cc so I'd be tempted to go 750cc based upon 80% duty cycle.
Lean - I think this maybe the case if you dont have a DCAI as the engine will not be wanting to draw aginst the 0.7psi drag on the intake.
A wavetrack will assist with traction + save tyres.
