We know acceleration times are very dependent upon the amount of weight the engine needs to move. How much weight does the 911 need to shed to be .1 seconds faster to say 60? 100lbs? 200? Just a random thought flowing my brain today. It started while observing most professional racers are small in stature and wondering if say 30/60 lbs on someone makes much of a difference and at what lbs it does.

 

Seems like 0.1s per 100lbs, I used this calculator.

I'll tell you this. Both my 997 and 991 were/are noticeably slower in any acceleration with a passenger on board.

 

Nice find thanks

 

Ok, ok. I'll go on the diet!

 

ive lost 40lb in last year,my car has to be faster now:}
I know its a hella lot easier getting in and out

 

Congrats on that.

Lose weight, P-car goes faster. Now I have my incentive!

 

I know that this has to be taken with a grain of salt (you have to be extremely consistent and with little traffic for it to make sense), but my best lap times are typically 1s better with no passenger, all other things being equal: same day and conditions, same amount of gas in the tank etc. Now this can just be a coincidence...

 

No salt Serge, I am on a go faster diet - it will make me retain fluids!

Seriously, our weight can be a big issue when you are buying a racing bicycle. It is much cheaper to lose a few pounds than pay for a bicycle that is a few ounces lighter, pass the salad. Otherwise, pass the cheeseburgers!

 

It is much more fun to not have to lose a few pounds, have a $12k race bike and eat cheeseburgers when ever you want to.

 

I wonder all who contributed so far ...how many of them are engineers by training/education. I'm one but not sure if this is the problem I'd like to solve or think about. I just love how this thing drives/handles and may be this topic is a good datapoint....I'll be paying some attention

 

Do chemists count? Do really bad chemists who went to law school because they could not balance an equation count?

 

Lose some weight for that .1 second faster car or pay $15k for power kit to get it.

 

FYI, do not turn to your date or wife and say that while driving the car.

 

The correct thing to do is:

Always tell your wife she is providing additional weight to balance out the handling, and then tell your date she is helping provide down-force to the rear.
