Horsepower Variations?

[TheEdgeofSanity]

I don't understand how the LA1 can have only 170 hp in an alero and grand am, but 180 hp in the impala and monte carlo and 185 hp in the chevy venture (and related vans) ... what's so different that gives it an extra 10-15 horses?

[AbHeLlRaZoR]

possibly the way they are tuned from factory look at the differences in sizes each vehicle has as the vehicle gets heavier they come with more horsepower. keep in mind each of the vehicles you listed were designed to be economical.

[Redog]

Yeah it all comes down to the program that model car has.

Also the venture has the 4t65 tranny

[TheEdgeofSanity]

so, why wouldn't they tune the alero and grand am to have that same power? I only question this because my grandma's 2000 malibu has the 3100 and it is rated at 170 hp, which is the same as the 3400 and it seems dumb that a car with .3 more liters would have the same power. can I tune my car to match the tuning of the impala and not have to run premium fuel?

[Redog]

Because the different divisions of GM where like that

Chevy was the basic car, Olds and Buick are the luxury line below Caddie, and Pontaic is the "fast" car.

Plus different models like the Venture line are going to need more power. An Alero weighs in at 3300 lbs and the Venture around 3950 lbs.

(I knoiw this because I'm looking at either a Bravada or Olds minivan now. Don't worry, it's going to be a brother to Redog not a trade)

bravada FTW

3300LB alero? yours is overweight. They only weigh ~3000LB V6 is around 3024, 4cyl 2960

[99alerogirl]

mine is a high 32xx... with the V6 and GLS package..

[JLw7123]

mine says 4000 pounds that can not be right.

[AZFire316]

Yeah, definatly not 4000LBS curb weight, you'd be weighing in similar to what a Chrysler 300 does.

[JLw7123]

ya that is what I think because it can not be 4000 pounds

[AZFire316]

even 3200 seems a little bit high for an alero, they should be around ~3000
