Let's then use a car w/ a somewhat similar power/weight ratio--the e36 M3. Power/weight = ~12.9
Twins power/weight= ~13.7

The M3 typically traps ~99 w/ slightly better power/weight, but ~5-6mph?

Are BMWs underrated as well?

I have other examples...

We were sold a bag of HP goods! lol
I don't know what kind of math you're using. Make sure you use weight of the vehicle with the driver and fluids. This is the equation.

hp = weight ([trapspeed/234]^3)

Using this equation, with 2900 as the weight and 92mph as the trap speed...you get 176whp. Which seems about on par with what 200hp should be. About 12% drivetrain loss.
