300 hp quarter-mile times by weight
| Race weight | 1/4 mile ET | Trap speed | 0–60 (RWD) | lb per hp |
|---|---|---|---|---|
| 2,200 lb | 11.32 s | 120.4 mph | 3.74 s | 7.33 |
| 2,600 lb | 11.97 s | 113.9 mph | 4.28 s | 8.67 |
| 3,000 lb | 12.55 s | 108.6 mph | 4.80 s | 10.00 |
| 3,400 lb | 13.08 s | 104.2 mph | 5.30 s | 11.33 |
| 3,800 lb | 13.58 s | 100.4 mph | 5.79 s | 12.67 |
| 4,200 lb | 14.04 s | 97.1 mph | 6.28 s | 14.00 |
| 4,600 lb | 14.47 s | 94.2 mph | 6.75 s | 15.33 |
300 hp is serious street performance: territory for modern muscle and sports cars and well-built tuner cars. 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 300 hp need to run a certain ET?
| Target ET | Max weight at 300 hp | Trap speed |
|---|---|---|
| 14.00 s | 4,165 lb | 97.4 mph |
| 13.00 s | 3,335 lb | 104.9 mph |
| 12.00 s | 2,623 lb | 113.6 mph |
| 11.00 s | 2,020 lb | 123.9 mph |
| 10.00 s | 1,518 lb | 136.3 mph |
| 9.00 s | 1,107 lb | 151.5 mph |
For example, 300 hp is enough to run a 12.00 second quarter in a car up to 2,623 lb, and a 10.00 second pass at 1,518 lb or lighter.
300 hp compared with 250 and 350 hp
At 3,500 lb, going from 250 to 300 hp saves 0.83 s, and going on to 350 hp saves a further 0.66 s. Gains shrink as power rises because ET follows a cube root, so the same 50 hp is worth less each time. At 300 hp, the 1/8-mile ET for 3,500 lb is about 8.47 s at 82.5 mph.
The power-to-weight of a 3,500 lb car with 300 hp is 11.67 lb per hp, or 189 hp per tonne. See all horsepower comparisons.
