We're missing some information.

What does his car weight, and what did yours dyno at?

Motors are different from build to build.

The same setup will always differ.

94 teg's weigh around 2500lbs.
power to weight = weight / power ( which gives you weight to power ratio )

I think your'e forgetting a very very important point...Gear Ratio...If your tranny is geared shorter than his and/or your wheel/tire size is shorter than his, you will have a larger amount of torque being transfered to the ground...This will make all the difference in acceleration...
