Dynocom dynos compute power numbers to whp and wtq. Dynocom dynos read quite a bit higher (~15%) than a Dynojet dyno. On a Dynojet (which is the dyno most use), the numbers would be around 410-420whp and 450-460wtq which is about what I'd expect for the mods and an ethanol tune and stock turbo.

Without a log or knowing how much timing, it's hard to believe 480/540+ on the stock turbo at 18.5lbs of boost.

Your map certainly runs more timing than any OTS. The closest OTS map to your custom map is probably BM3 e30 stage 2+ which runs 21 psi and 13 degrees of timing.
The log above shows you running 18 degrees of timing with a target of 18.5psi of boost. It would be interesting to see a bit more boost with the higher timing. There’s definitely room for more power over the stage 2+ OTS IMO. |

At your peak hp ~5100rpm, there's only 9.5 degrees of timing and 18.5lbs of boost, at peak torque you have 7 degrees of timing and 20.6lbs of boost. The max MAF HFM you hit is about 40.2 on one pull. For comparison the stage 2+ is at 11 degrees of timing and 19lbs of boost at 5100rpm, at 4000rpm its at 9 degrees of timing and 21.5lbs of boost, and maxes out the MAF HFM at 41.3. I'm not saying there isn't a gain to be had over the stage 2+, but I'm having a difficult time believing that dyno isn't inflating numbers. Last edited by 5w20; 09-26-2021 at 03:41 PM.. |
