ok theres a bunch of cars that have the series 2 right? and all the ones ive seen like in magazines and whatnot list them as producing 200 horsepower. all of them except for the Bonneville which says 205.i know thats not much a difference but what is it that makes ours just slightly more powerful? hey i was in school in a boring class so this was what was runnin through my mind.

The LaSabre and the Park Avenue NA'* have the same motor. I guess Riverea'* too! I think its weight relative so they both are equal. Bill help me out here.

The smaller cars have a more restrictive exhaust. That accounts for about five ponies.

My gut feeling on this is that the smaller cars ARE lighter, but because of the size, the intake and the exhaust are more restrictive....which explains why they're rated lower. My observations lately have been that the lower hp and tq figures make up the difference for us in weight.....so a GTP that weighs 400 pounds less than us is equal....because he has less power. Whether or not the 5/5 less is enough to make up for 400 pounds is a question that would be tough to answer considering the different factory gearing.

well thanks now i know. i was just curious as to why we had just a little bit more.

also is the 205 for the SE or SSE? cause i would think the SSE'* exhaust would flow better than the SEs? thus creating more ponies? this one occured while i was takin a pee(some of the best thoughts come at that time)

Funny you should mention that. I think the SE, SLE, and SSE are all rated the same in output, but I'd expect the more restrictive exhaust on the SE to perhaps deliver that same power at a higher RPM.

Any takers?

I dont' think the 'dual' exhaust makes much of a difference.. it is mostly for looks anyway. It'* more a dual outlet setup.

hey, i agree with ya there . plus its more efficient as well for having dual exhaust other than the appearance. the downside is that you incur the cost of two sets of pipes. for every plus, there is always a minus . if anyone thinks/believes that they are gettin more power for having "duals"......theyre sadly mistaken. take care and ride on !!!

If I'm not mistaken, the SE has 2.25" pipes, the SSE, SLE, and SSEi have 2.5". Can someone with an SE confirm this?
