FWD vs. AWD Pull
Is it true that two cars with identical horse power with one being awd and the other fwd, the awd will pull you back more to your seat? I test drove a bone stock sti and that thing was pulling me back hard even after 45mph punch. And rwd, I think they pull you back harder too in terms of displacement.

All in how they hook up... identical hp means of the three, AWD is going to get the least power to the wheels, but will get the highest percentage of that to the ground, assuming identical tires.

If traction is a factor (wheel spin) AWD will (99% likely) accelerate faster.
If traction is not a factor (no wheel spin) FWD will accelerate faster, the extra drive line components in AWD add weight and increase frictional and inertia losses.

My ss/tc is about 290 @ the wheels, I punched it in 2nd at 40mph and hooked up uintil 5.2k rpms and I did the same thing on a stock STi it pulled alot harder even tho I was in 3rd at 40mph when I gunned it. I dont get it I have more torque, car hooked to certain rpms yet I didnt feel the pull as great as the AWD.

as said above, assuming traction is NOT an issue (IE neither car spins or hops or anything) such as from a higher speed roll, then the FWD car willbe the fastest.
another thing to take into account though is do both cars have identical gearing? Cause the answer here is almost certainly no.

Honestly the AWD platform that sees the least amount of top end power loss is the EVO. The EVO has a higer RL and better all around gearing.

True that. I also drove my douchebag's friends stock m3 (notice the corelation douchebag and m3 haha) anyways it seems to pull you back pretty good also. I guess its just fwd that doesnt pull back hard even if it hooks.

Not true, when I raced my buddies sti (different one 3202whp)and beat hime, my other friend was with me who drove the sti also said he didnt feel the pull even tho I won. It was a race from 50-110 and even though I started in 2nd.

Some say gradual constant increasing G forces feel like the strongest pull, as you are accelerating over a longer period of time, but the magnitude of accel would be less, meaning you would actually be going slower. This type of bulling FYI is what a lot of turbo cars or high revving hondas deliver.
at the end of the day though, instantaneous pulling is proportional to instantaneous accel.
Hell, there are products that measure the amount of G forces you're pulling in the car and calculate acceleration and HP off of it.

The sensation of pulling is caused by G forces. G forces directly relate to acceleration.

a friend of mine gad a 180 hp turbo saturn sc2. that mother ****** would pin you in the seat. the reason was turbo lag. the boost hit you out of nowhere. my mustang felt faster than my ss, but thats because the tq was instant on the gt. another thing that makes on car feel faster is noise and how smooth the ride is. a lot can contribute to a car "feeling" faster.
