800 hp quarter-mile times by weight
| Race weight | 1/4 mile ET | Trap speed | 0–60 (RWD) | lb per hp |
|---|---|---|---|---|
| 2,200 lb | 8.16 s | 167.0 mph | 1.71 s | 2.75 |
| 2,600 lb | 8.63 s | 158.0 mph | 1.95 s | 3.25 |
| 3,000 lb | 9.05 s | 150.6 mph | 2.19 s | 3.75 |
| 3,400 lb | 9.44 s | 144.5 mph | 2.42 s | 4.25 |
| 3,800 lb | 9.79 s | 139.2 mph | 2.64 s | 4.75 |
| 4,200 lb | 10.12 s | 134.6 mph | 2.86 s | 5.25 |
| 4,600 lb | 10.44 s | 130.6 mph | 3.08 s | 5.75 |
800 hp is hypercar-level power: figures usually seen in factory flagships and serious tuned builds. These numbers come from the ideal-traction formula, so treat the quicker end of each range as a best case.
The estimate uses the widely published Patrick Hale equations: ET = 5.825 × (weight ÷ hp)1/3 and MPH = 234 × (hp ÷ weight)1/3, with weight in pounds and hp measured at the crank. They are documented, along with the more conservative Huntington (6.290 / 224) and Fox constants, in Stealth316’s horsepower / ET / MPH calculator notes. See the full formulas and sources page.
What weight does 800 hp need to run a certain ET?
| Target ET | Max weight at 800 hp | Trap speed |
|---|---|---|
| 14.00 s | 11,107 lb | 97.4 mph |
| 13.00 s | 8,893 lb | 104.9 mph |
| 12.00 s | 6,994 lb | 113.6 mph |
| 11.00 s | 5,387 lb | 123.9 mph |
| 10.00 s | 4,048 lb | 136.3 mph |
| 9.00 s | 2,951 lb | 151.5 mph |
For example, 800 hp is enough to run a 12.00 second quarter in a car up to 6,994 lb, and a 10.00 second pass at 4,048 lb or lighter.
800 hp compared with 750 and 850 hp
At 3,500 lb, going from 750 to 800 hp saves 0.21 s, and going on to 850 hp saves a further 0.19 s. Gains shrink as power rises because ET follows a cube root, so the same 50 hp is worth less each time. At 800 hp, the 1/8-mile ET for 3,500 lb is about 6.11 s at 114.5 mph.
The power-to-weight of a 3,500 lb car with 800 hp is 4.38 lb per hp, or 504 hp per tonne. See all horsepower comparisons.
