Go to the drag strip and let's see what this modified '83 of yours can do.

Sorry to hear it.

No, I was goading him a bit into sharing his vision of the events.


Better yet, I need to get on a dyno and get real data for you Imo.

I would never exaggerate the facts here. That Bimmer could Not lose me. It is 1000 lbs heavier though.

I certainly would never make fun of a fellow 928 owner...

But Yuppies? Sheesh ! Yuppies !!!!!








All in fun ! ! ! !

Forget the dyno, take it to the strip and get some real numbers. 1K lbs is good for around 1 second faster in the 1/4. I totally beleive you, have no reason not to but a time slip is where the real proof is.

Maybe the Bimmer was a rebadged 320i?

HP sells cars, torque wins Races. I can say that because kibort is on mute.

Your weight reduction is what helped you. I can take 335s easily in the E55, but because of 500hp, not because of weight. A stock, normal weight 928 will have issues even with some of the newer V6 japanese sedans.

Say it three tines and he will appear

I want to dyno to know the gains.

Sheesh. It was one of these: https://www.google.com/url?sa=t&rct=...30839,d.cWwbmw 335i, 300 hp and 300 lbft torque


Your preaching to the choir.


They only have 300 lb ft of torque, with the added 1000 lbs and frontal mass, the math works out in my favor. This is a big car.

I went down to the garage and took out my factory Owner's Manual.

1983 Manual weight: 3351
Acceleration 0-60 6,8 sec at curb weight WITH half load capacity.
Half load capacity: 341.5 lbs
Total weight for factory 0-60 time: 3692.5 lbs with stock 234 HP / 263 lb ft

My RS weighs about 2700 lbs. I weigh 180 dressed, Astrid 120 i think.

Total embarrass new Bemmer weight in RS about 3000 lbs.

BMW 335i weight 3750 lbs plus 2 yuppies estimated at 350 lbs.: total 4100 lbs

So he likely had a 1000 lb weight disadvantage.

This is all the data I've got at this time,
other than he wouldn't even look over at me at the red lights.
dyno when i get the time.

Sorry, but I take issue with it too. Peak torque or peak horsepower is almost meaningless.

Speed, via acceleration, is what wins races! Instantaneous power is the easiest to convert to acceleration.
Not torque?!

The drag strip is for cars that can't corner!

"BMW 335i weight 3750 lbs plus
2 yuppies estimated at 350 lbs.: total 4100 lbs"

Not so fast there Pythagoras.....

Everybody knows Yuppies are commonly known in the wild as "Air-Heads".

But, Yuppies are also overly self-absorbed which gives them "The Big Head"

This increases the Air Head displacement by the Big Head Factor (BHF) which is 3879.33333

Giving us 2{3879.3(10)} = approx 77,580 pounds.
Thus rendering the BMW weightless.

An even greater feat of easy-going prowess for the indomitable 928 ! !

Did you dyno it before you did any work? If not, there is no point to compare it to. The 1/4 mile time slip is the ONLY thing that proves how fast a car is in a drag race. After all, this was a drag race, nothing more so a good trip down the 1420 is the only thing that proves anything. Everything else is just "magazine racing".

Also, why the heck do you keep calling your car an RS? It's a modified '83 US model and will always remain that regardless of the sticker on the trunk.

rnixon

The issue is that weightless does not equal mass-less, so the BMW would not be able to accelerate, as there'd be little to no friction at the tyres, but still the same mass to accelerate. BMW drivers make these kind of mistakes
