As mentioned by SGirl on the kiddy-seat thread, we chucked the Cerb (pics coming when it stops peeing down) on the Rolling Road at Power Engineering, and we got what I assume are reasonable out of the box figures: 254 bhp at the wheel(s), 336 flywheel at 6066 rpm, but "only" 298 Lbs/ft torque.

A set of Nitron dampers/stiffer strings are clearly on the shopping list, but engine-side, I seem to remember reading a while ago a point by DannyLT that Joolz has an induction side fix that gives a wee bit more torque. Anyone had this done/any thoughts on the matter?

joospeed said: that torque is quite low .. More important than peak torque is the spread though .. if you've got 298 all the way from 2k revs upwards then don't worry too much ...


Thanks to all for input.

Joolz, no doubt you will see the Cerb sooner rather than later (ever thought of moving down south? Much higher house prices, crowded roads, superb trafic calming schemes..you know it makes sense), so we can discuss the 1000 & 1 reasons. Torque at 2750 is 270, and "peaks" at what looks like 5500, then goes south at about 6100. (Not in work. Can't scan)

As far as preliminary investigations reveal, the thing's got a 4.5 back box (baffles periodically patched up by just about every independent in the car's history, judging by the receipts), and the fact that the Lambda sensors seem not to be wired up to anything leads me to suspect I need to check whether the cats are present & accounted for still, it's got a fresh MOT from the dealer..so it MUST be ok
