Anyone tell me what capacity the Q alternator is?The ZX one is 90A, but as I now have electric water pump, PAS pump and cooling fan to run too it might be worth looking at a Q45 one if its bigger.Would solve the mounting problems anyway!

Q45= 110 amperes.

However important to compare the amps vs rpm [crank pulley vs alt pulley diameter].

Thanks. Was going to make the new pulleys to turn it at it's max running speed at stock rev limit when my engine is at it's higher rev limit.
