Hi TurboFreaks,
We (Kent Auto Developments in the UK and I) are building a
Mini-Cooper (a charming little front-wheel-drive car that goes like a
striped-a** ape) using a ZZR1100 as the engine. The Mini will come
in at around 1500lbs (682kg) with engine and my fat-a** strapped in.
The plan is to use the ZZR1100 as a "mule" engine until we get
everything sorted. After that, the plan is to turbo-charge
(probably) or super-charge (maybe) a big-bore version of the same
engine. (Don't worry, we pretty much have the reverse gear part
figured out.) I'm looking for an engine result of something like
225hp and 150lb-ft of torque. (Torque is of more value than
horse-power.) Other than the fact that the engine alone will
probably cost about $10 grand, I have other concerns.
Will the stock gearbox handle this? I doubt it because of the
automotive shock loads, even with all of the "cush-drive"
arrangements. [By the way, the gearbox output sprocket will
chain-drive a Quaiffe differential, which will (in turn) drive two
constant-velocity shafts via cogged-belts. (Trying to mitigate the
shock loads as much as possible.)] Will high-strength road-racing
gears take it? Am I better off going with a drag-racing gearbox with
fewer ratios and stronger gears? I can use, but really don't "need"
six speeds. Any thoughts, comments and/or ideas will be appreciated.
Thanks in advance for your advice.
Cordially,
Rich Crispin
