I can't tell if you guys are pulling my leg...

Do you understand the following?
  1. What is typically shown on a power & torque vs RPM dyno chart is wheel power, but is not wheel torque (rather it's engine torque minus system losses).
  2. Cars make more torque at the wheels than they do at the engine due to the fact that your engine spins faster than your wheels (and gearing multiplies your engine torque).
If so, it's nonsensical for you to write "2k gets you 70-80 whp- 80-100 wtq. In a tc that's probably about 20-25 whp-10-15 wtq." and "And another thing 300wtq on FWD is epic fail".

Did I claim otherwise? I don't hate FWD because it's slow (it isn't). I hate FWD because (all else being equal) it's not as fun. Of course, all else is not always equal and I'd rather drive a MCS than a V6 Mustang. But thanks to the FT, I won't have to settle for either of them.

You used the term wtq to describe something that is not wheel torque (after I thought it had been explained).

Not making much sense and I'm not the only one not getting what he's talking about with the the whole wtq comments. WTQ stands for wheel torque in the gear that's closest to 1:1 ratio on a Dyno, it doesn't need to be any more complicated than that.


The overall ratio isn't anywhere near 1:1 in any gear. For most cars, it's in the ballpark of:

1st gear 12.0:1 to 16.5:1
top gear 2.5:1 to 4:1

Please reread what I wrote about how much wheel torque an S2k and MX5 make, and see my response to SUB-FT86 earlier in this post.
