350 hp quarter-mile times by weight
| Race weight | 1/4 mile ET | Trap speed | 0–60 (RWD) | lb per hp |
|---|---|---|---|---|
| 2,200 lb | 10.75 s | 126.8 mph | 3.31 s | 6.29 |
| 2,600 lb | 11.37 s | 119.9 mph | 3.78 s | 7.43 |
| 3,000 lb | 11.92 s | 114.3 mph | 4.24 s | 8.57 |
| 3,400 lb | 12.43 s | 109.7 mph | 4.69 s | 9.71 |
| 3,800 lb | 12.90 s | 105.7 mph | 5.12 s | 10.86 |
| 4,200 lb | 13.34 s | 102.2 mph | 5.55 s | 12.00 |
| 4,600 lb | 13.75 s | 99.2 mph | 5.97 s | 13.14 |
350 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 350 hp need to run a certain ET?
| Target ET | Max weight at 350 hp | Trap speed |
|---|---|---|
| 14.00 s | 4,859 lb | 97.4 mph |
| 13.00 s | 3,891 lb | 104.9 mph |
| 12.00 s | 3,060 lb | 113.6 mph |
| 11.00 s | 2,357 lb | 123.9 mph |
| 10.00 s | 1,771 lb | 136.3 mph |
| 9.00 s | 1,291 lb | 151.5 mph |
For example, 350 hp is enough to run a 12.00 second quarter in a car up to 3,060 lb, and a 10.00 second pass at 1,771 lb or lighter.
350 hp compared with 300 and 400 hp
At 3,500 lb, going from 300 to 350 hp saves 0.66 s, and going on to 400 hp saves a further 0.55 s. Gains shrink as power rises because ET follows a cube root, so the same 50 hp is worth less each time. At 350 hp, the 1/8-mile ET for 3,500 lb is about 8.04 s at 86.9 mph.
The power-to-weight of a 3,500 lb car with 350 hp is 10.00 lb per hp, or 220 hp per tonne. See all horsepower comparisons.
