Yes, this is true. I saw the engineers present this at the Society of Automotive Engineers Motorsports Conference in 1998 in Detroit. They use the F1 TV in car camera feed so there is no Dopler shift to filter out. Very accurate. From acustic information, power, gearing, and downforce can be estimated quite closely. | ||

actually when they released the info on the bmw williams they said it had about 930hp and the ferrari was supposed to have the highest in F1 this year, so actually it could be around 950hp. the article i read in race car engineering about figuring hp by the acoustic signature of the engine was pretty interesting though. teams would record engine sound and try to figure out how much hp the opponents ran. they came up with the equation f=SN/120 where f was the frequency, s being crank speed, and n being the number of cylinders. of course there are probably numerous other factors that could fray their numbers, but it probably gave a pretty decent estimate. | ||

Mitch, as Rob stated, they use a 96ish Octane gas. | ||

Yah if I remember correctly I've heard it's around 340 ft-lbs of torque. I believe the regulations stipulate pump gas. | ||

Thanks for the info. | ||

Mitch, great answer. Though I thought the regulations stated 'pump fuel', which is something like 96 (ron+mon)/2. The days of hyper-expensive custom brews were gone? | ||

I looked at quite a few sites and HP and Torque are always listed as "N/A"; makes sense I suppose as that would be very proprietary/confidential information. But I'd like to know. | ||

TQ is mainly a function of displacement and compression. With 3.0 litres of displacement and a compression in the 13:1-14:1 range and the exotic fuel used in F1 cars, one can expect 270 lb-ft of TQ. I expect this TQ to be pretty flat from its peak around 14K RPMs to HP peak in the 18K-19K range. Say we loose 20 lb-ft from 14K to 19K: HP is a function of TQ and or RPM (HP=TQ*RPM/5252), so you get 850 HP with 250 lb-ft of TQ at 18K RPMs, or 900 at 19K RPMs. At least this gives some working estimates that are in line with known data (850+ HP and 19K RPMs) | ||

I am just curious as to how much torque the '03 F1 Ferrari has. I'm not sure, but it has around 900 HP right? I heard the torque was really low, but I can't even guess on the matter. Thanks! |
