Hi all
Im thinking of building a challenge vehicle, north offroad which is the best engine box combination do you think?.

Torque to STOP wheel spin really200 or 300tdi - plenty of power to be released from within them, loads of torque to stop wheel spin. go for the r380 box as it does seem to be better than the lt77 for taking some hammer
if an engine can be driven on its low down torque characteristics that then negates wheel spin - have you never wondered why the WRC rally cars have a massive torque figure but are limited to only 300bhp - they can shred there tyres through grip within 25km - not wheel spin that is induced by bhpTorque to STOP wheel spin really
No i have never wondered why that is, there restricted via a turbo restrictor, the 300ps limit is due to the amount of air that can get through that restictor and this if i remember correctly was done for safety reasons.if an engine can be driven on its low down torque characteristics that then negates wheel spin - have you never wondered why the WRC rally cars have a massive torque figure but are limited to only 300bhp - they can shred there tyres through grip within 25km - not wheel spin that is induced by bhp
you are correct about the engine bhp being limited by the use of restrictors, which is why in conjunction with the tyre makers (Pirrelli and Michelin) they then found that by increasing the torque figure the tyres where gripping better than had ever happened in the group B era so the times on stages are quicker than in years gone past. Having spent the last 8 years as part of the Ford WRC test team I think I am qualified to pass comment that is fact.No i have never wondered why that is, there restricted via a turbo restrictor, the 300ps limit is due to the amount of air that can get through that restictor and this if i remember correctly was done for safety reasons.
Well your never to old to learn something.

also after increasing the low down torque of my 300tdi I am now able to climb up loose surface hills/tracks that before I was expeiriencing wheelspin in 2nd gear but am now able to climb the same hills/tracks in 3rd gear because of the increase in torque through less wheelspin.
