Default Q; Power to weight

How large does your car have to bee before the weight really makes a big diffrence?
Reason I ask, my freinds 01, 02 civic stick can keep up with my car, but the bonnie is supposed to have 175hp right? So does weight really play that big of a deal in street cars? IE BONNIE 97 se.

your 97 will have 205 hp, you must realize that out cars weigh alot more than a Civic, but the torque of the engines is what really matters

Same here. I like off the line power. Freeway power, ehh. who wants a speeding ticket anyways? I just got a car and driver magazine from 96'. My LSS goes from 0-60 in 6.8 sec and a Honda Civic 5 speed manual in 7.9 sec. Isn't that /honda'* the samre as a series II NA? I don't know i'm drunk anyways.

Highway speed is the best, IMO. My car feels faster on the highway, then it does on the street, compared to when I floor it for each scenerio. I think its pretty good that a sedan can hang with a light civic to begin with.

I dunno, it seems most superchargers now-a-days are to compensate, rather than add an advantage. I mean heck, 3.8 supercharged SII = 240hp, naturally aspirated 3.0 in an Accord = 240hp. Meh...

Weight always plays a big role in vehicles. For example, at 3600lbs and 205hp you have 17.5lbs per HP to lug around. A 2001 civic with 127hp and about 2400lbs has 18.8lbs per hp. BUT suppose an 18% driveline loss in the automatic Bonnie and only 12% in the 5speed Civic and that goes to 21.4lbs for BOTH cars. Funny how that works out eh?

For reference, the Ferrari Enzo has 4.56lbs per HP...mmmmmm

thank you sir. Wow I will definately take that into consideration.
What besides, the four door factor causes the bonie to weigh so damn much?

NP....Its large size, wide stance, plush interior, larger engine, probably a thick frame, larger tires, then all the heavier components that have to carry that weight (suspension and such). All sorts of things contribute to its weight. I wouldn't say its so much one or two pieces that really do it, its a combination of 20lbs here and 40lbs there. That stuff adds up quick though.
