Lets torque performance.com NISR227s updated site

[Fast Guy]

I thought this might be of use/interest to some people, so I dug it up for people to see again.

I've been playing around with my performance (all types of cars) THEORY spreasheet, and its formulas, and now finally added a 0-100mph formula of my own too, so allowing for the poor areodynamics of Pulsars, here's what it comes up with:

bhp kg bhpton 60 ..100...... 1/4. Termspeed
...........................*..............................
220 1250 179 5.54 15.30..... 13.92 95.84

276 1250 224 4.52 11.73..... 12.84 105.17
290 1250 236 4.33 11.12..... 12.64 107.16
290 1210 244 4.22 10.83..... 12.53 108.09
300 1250 244 4.21 10.73..... 12.51 108.52
320 1250 260 3.99 10.05..... 12.27 111.06
350 1250 284 3.73 9.22..... 11.98 114.54
370 1250 301 3.58 8.76..... 11.81 116.66
400 1250 325 3.39 8.18..... 11.59 119.59
400 1100 369 3.13 7.68..... 11.33 122.09
450 1100 416 2.94 7.06..... 11.09 125.97
500 1250 406 2.98 6.86..... 11.08 127.66
500 1100 462 2.82 6.60..... 10.92 129.30




And these are the same with 0.5 secs added to the 0-60 to allow for a slightly more careful launching and some for gearchanging (probably closer to real times achieved in most cases):

.............................*..............................
bhp kg bhpton 60 ..100...... 1/4.... Termspeed
220 1250 179 6.04 16.96..... 14.42 92.68

276 1250 224 5.02 13.09..... 13.34 101.47
290 1250 236 4.83 12.43..... 13.14 103.34
290 1210 244 4.72 12.12..... 13.03 104.20
300 1250 244 4.71 12.01..... 13.01 104.61
320 1250 260 4.49 11.27..... 12.77 107.01
350 1250 284 4.23 10.36..... 12.48 110.29
370 1250 301 4.08 9.86..... 12.31 112.29
400 1250 325 3.89 9.22..... 12.09 115.06
400 1100 369 3.63 8.68..... 11.83 117.35
450 1100 416 3.44 7.99..... 11.59 121.03
500 1250 406 3.48 7.77..... 11.58 122.70
500 1100 462 3.32 7.48..... 11.42 124.21

Its difficult to know if the 0-100 times are anywhere near correct becuase not many people get them offically recored, let alone at a drag strip like Santapod. The formula is connected to the terminal speed formula and time, so if you went over the line at exactly 100mph then it will caluclate the same 0-100 figure, and so on.

Check out NISR227s site at

http://www.letstorquebhp.com/default.asp

Direct link to the performance calculator


You can find out the 0-60/100 and 1/4mile times of most (if not all) performance cars on that site

You can work out the times for your own car with the performance calculator.

Thanks fastguy, I've worked hard on the site, improved formulas and figures, but if anyone is interested, here's the update text thats going on loads of forums this week... (there's a pic me on the homepage, and me with the R on the team section )..


www.letstorquebhp.com UPDATE

Please check out our new and now updated site about THEORY PERFORMANCE AND STATISTICS.

After the previous development site, we have now updated to a more professional look with many new features:
- new enhanced performance calculator with improved formulas for 0-60, 0-100 and 1/4mile etc
- updated theory stats for 1000's of cars, now with sort options
- articles on the Evo MR340, and Bugatti Veyron theory figures
- detailed 2005 event calendar (UK)
- many recommended links including UK club forums, other stat sites, circuit/track day sites, and other useful links

If you are interested then add it to your favourites and check for regular future updates:

NISR227- could you work out the performance figures for an R running 1 bar of boost?

 

[Fast Guy]

If you know the weight and power of your car, have a play with his performance calculator. If you just want to know what power you'll get at 1bar, his site won't tell you, but it'll be around 275bhp with filter and exhaust.

He has a 1bar Gtir on his 4x4 listings, he lists it as 290bhp which I think's abit optomstic (but possible).

 

[hmmm]

...

It's definately possible. Mine is running 298bhp at 1 bar (Powerstation). But you never know, could have been an inaccurate reading, although I really hope it's not .

We had Duey's car dynoed at 1bar at the PowerStation and produced 296bhp at the flywheel,about 2 months later it was rolled at Thor(AHMMM)and produced the same figure on a power run before being mapped to 1.2bar.They also had mine at 293bhp@1bar before they cocked it up

Nice one guys I'll have a play with the performance calculator thingy...
