RE: Exhaust Problem

[Bradley Peet <btpeet@effervescent.com>]

Most 1983-1987 1.8 liters sold in the US make 85 (base model Golf, Jetta, 
Fox) or 90 hp (Scirocco) depending on the emission equipment and the exact 
model of car.  I believe the Digifant equipped 1.8 liter engines in 1988 and 
up make 100 hp, again it depends on the model (the exhaust system in 
particular).  Don't some of the later 1.8 GTI/GLI engines put out 105 hp 
stock?

Anyway... my main point is that the formula for horsepower has NOTHING to do 
with bore and stroke.  That's displacement you're thinking of.  For an actual 
horsepower figure, you need to know the torque at a given RPM.  That's how 
dyno's work, by directly or indirectly measuring torque.  The formula for HP 
is:

HP = RPM x Torque (ft-lbs) / 5252

Class dismissed. :)
