[QUOTE="AE80TypeD, post: 277436, member: 722"] hahaha of course torque oso rises... but ideally for 4WD since there are many links in the drive transmission that can slow down in respect of momentum quickly; we'd want a torque curve that maxes in the low-mid rpm range so that upshifting doesnt suffer a lag, a compared to high revving motors which need to "re"build momentum at every upshift. have u played NFSU2? notice the dyno graphs for certain cars, generally the ones with default big cc engines/v engines. see that their torque curve peaks out in the middle instead of the redline, giving them excellent pickup from any gear at lower RPMs. compare this to the RX or AE86 dyno graph. there the torque & hp rises accordingly bcoz they are made that way. all im saying now is, we would actually prefer the former power figures (earlier max torque) in a 4WD system rather then the power provided by a peaky engine like the 4AGE to compensate for the heavier drive system (more parts between the engine and the wheels to turn). various driveshafts/longshafts/axles and gears in the 4WD system would slow down faster then 2WD drivetrains, dont u agree? an engine that builds max torque at higher revs would spend more time rebuilding momentum of the moving parts. im stating it as a "more suitable" application, not saying that 4AGEs SHOULDNT run 4WD systems at all.
