Pick one :) unless its a 7 speed DSG unit from VW its one or the other.
ran some calculations on how the AMR500 supercharger would fair up on the Z14XE
Supercharger: AMR500 (Small i know but hear me out)
Dimensions: 170mm Long x 180mm wide x 130mm tall
Displacement: 500cc per revolution.
Safe working limit: 16000rpm
1.4L x 6500( Assumed redline) = 9100/2 = 4550 liters per min
5(psi)+14.7(psi at atmo) = 19.7/14.7 = a boost ratio of 1.340 br
Air requirement at Boost
4550(lpm)x1.340(br) = 6097 Liters per min at 5psi at 6500rpm
Charger rpm required
6097/0.5(charger displacement) = 12194rpm (safe working limit for the AMR500 is 16000rpm)
Pully ratio required
12194/6500(redline) = 1.876:1
Unsure of the Drive belt pully size on the Z14XE But can always work that out later
HP increase figures are as such:
1.4x8hp = 11.2hp (rough power increase per 1psi of boost)
11.2hp x 5psi = 56 hp
90hp (factory) + 56 = 146hp at the flywheel (not accounting for HP loss to drive the supercharger)
146x0.745= 108kw at the flywheel (not accounting for kw loss to drive the supercharger)
torque would equal 161nm at the flywheel @6500rpm, Substantially more lower down in the rev range(not accounting for HP loss to drive the supercharger)
= 42kw/51nm gain at 5psi
Pop in some z18xe injectors which will hopefully fit, Tune the ECU, Pop an exhaust on and have some fun :)
Unsure what the strength of the auto box is though. that would be the real question if it could keep up with the power.
