900 hp quarter-mile times by weight
| Race weight | 1/4 mile ET | Trap speed | 0–60 (RWD) | lb per hp |
|---|---|---|---|---|
| 2,200 lb | 7.85 s | 173.7 mph | 1.55 s | 2.44 |
| 2,600 lb | 8.30 s | 164.3 mph | 1.78 s | 2.89 |
| 3,000 lb | 8.70 s | 156.6 mph | 1.99 s | 3.33 |
| 3,400 lb | 9.07 s | 150.2 mph | 2.20 s | 3.78 |
| 3,800 lb | 9.41 s | 144.8 mph | 2.41 s | 4.22 |
| 4,200 lb | 9.73 s | 140.0 mph | 2.61 s | 4.67 |
| 4,600 lb | 10.03 s | 135.8 mph | 2.80 s | 5.11 |
900 hp is dedicated drag-racing power: the realm of extreme builds where traction and a safe chassis, not power, are the limits. 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 900 hp need to run a certain ET?
| Target ET | Max weight at 900 hp | Trap speed |
|---|---|---|
| 14.00 s | 12,495 lb | 97.4 mph |
| 13.00 s | 10,004 lb | 104.9 mph |
| 12.00 s | 7,869 lb | 113.6 mph |
| 11.00 s | 6,061 lb | 123.9 mph |
| 10.00 s | 4,554 lb | 136.3 mph |
| 9.00 s | 3,320 lb | 151.5 mph |
For example, 900 hp is enough to run a 12.00 second quarter in a car up to 7,869 lb, and a 10.00 second pass at 4,554 lb or lighter.
900 hp compared with 850 and 950 hp
At 3,500 lb, going from 850 to 900 hp saves 0.18 s, and going on to 950 hp saves a further 0.16 s. Gains shrink as power rises because ET follows a cube root, so the same 50 hp is worth less each time. At 900 hp, the 1/8-mile ET for 3,500 lb is about 5.87 s at 119.0 mph.
The power-to-weight of a 3,500 lb car with 900 hp is 3.89 lb per hp, or 567 hp per tonne. See all horsepower comparisons.
