I ran my buddies 98 328i auto tonight on the highway while I had two passengers equalling almost 400lbs in my car...

I usually pull on him easily....but tonight was different...I got about a car jump off the start from ~70mph....and then by 130 he was passing me....until he hit his speed limiter at 130something.

he had no one in his car....I can't believe how much of a difference 400lbs makes at even high speeds....

from now one...only one person (preferably a chick) is allowed in my car at one time

 

"weight reduction"

 

Own3d! hehehe

 

and whom may I ask was getting pulled on last time we ran above 100 a few weeks ago

 

maybe its the new motor??? hehe
have you raced him with this new motor yet? there is alot of debate over weight not mattering once your up to highway speeds. i feel weight doesnt matter as much but i think it still plays a role.

example
3000lb 190hp car
vs
2600lb 150hp car

in theory would be that at highway speeds the 190hp car would always win cause it has more horsepower and the weight wouldnt matter. dunno??

 

the new motor feels stronger than the old one all around....so I doubt it's that...I ran my brother Grand Prix before and after the new motor...and I beat him by more WITH the new motor....but I hadn't raced the 328 with the new motor until tonight...

 

i think im going to go for a run now amd then buy some SlimFast tomorrow

 

Weight matters whether you're at 0mph or 160mph. This is an engineer telling you this.

The laws of physics say F=ma, or (F/m)=a

The total force you can put out divided by your mass will give you the acceleration capabilities of your car. If weight mattered less at higher speeds then the formula would be...

F=(m/v)a, or [F/(m/v)]=a

This formula says the same thing only your velocity (speed) starts to cancel out your mass at higher speeds, but that is NOT how it works. It's F=ma, NOT F=(m/v)a, and Brian's race here proves that very nicely.

190 HP / (3000lb/2000) = 126.7 HP/ton
150 HP / (2600lb/2000) = 115.4 HP/ton
190 HP / (3400lb/2000) = 111.8 HP/ton

The Maxima wins not just because it has more horsepower, but rather because it maintains a better power to weight ratio than the other car. It has more weight, yes, but also more than enough power to compensate for that. But now look what happens when you add 400lb of passengers to the Maxima

 

toss the passengers..

 

exactly!

 

FYI most chicks are very unimpressed by racing, so why put that extra 130 lbs. in the car when you do that? I'd think a 328i would toast a max 6 ways to sundown, even an auto. Not sure but even a 98 may have been a 5-spd auto on the 328i, unless that tranny was reserved for the auto M3.

 

i still ran down my buddies 2k1 IS300 auto last night when i had me and three other people in the car and it was just him. gotta love mods.

 

Weight reduction is key. One can add as many mods as they want but if they're heavy, they'll never get the full effect of the mods.

 

Mass is the enemy of every aspect of vehicle performance.

A few weeks ago at the track theblue and I decided to have a little fun. We each took extra people in the car (me with two other 200lbs+ guys and him with 3 other smaller guys) for a run down the track.

Before this we we're both running 14.5's and 14.6's all night.

I ran a 16.8 and he ran a 17.2. It was quite funny.

"So that's what its like to drive a Honda..." - theblue

 

I was simply stating that as a joke, not that I'm going to have a chick in my car every time I race.
They are only 193hp and yes they do have a 5-speed auto....BUT they weight MORE than a 4th gen maxima. I have toasted E36 M3 AUTOS at highway speeds before...theres no reason I shouldn't be able to toast a 328 (which I've also done before)

 

You guys must have a lot of fun at the tracks up there. All of the tracks I've been to so far frow at having other people in the car.

Yeah, our track is really lax on the rules. Hell, unless you're deep into 12's you don't need a helmet.

 

 

Neal just be a smart@ss and state than your best N/A run is .4 off Brian's best 100 shot run

 

well i added subs, and that added some weight, but improved handleing alittle. i think that the subs cancel their own weight out though. i joke around and call them my "boost". the extra air flow lightens up the max and allows me to take off faster also. its all about timing and finding a bass song, the new eminem works pretty well....

 

I just took out my 2 subs + Box today, they probably weigh about 75lbs. I could feel a little more power because of the weight loss. It was great, now im building a much lighter enclosure.

 

You should build something that's easy to remove so when your ready to hit the track, you can just pop everything out with no porblems.
