Like the title says. I dyno'd my card today. It was a random dyno as I thought my cousin (who is taking a dyno tuning class at school) was suppose to dyno my car last week but it failed through. So he called me this morning and asked me to bring in my car. So I did. I didn't run a big fan infront of my car, when I should have because my temps got really high. I'm waiting on my teacher to email my dyno graphs and air fuel ratios. Because of some circumstances (one being my cousin doing the dyno run and not fully flooring my car, which might have been the reason why i ran lean the first run) I will be dynoing it again. But I'm pleased with the numbers.
Power mods (lol i wish they were):
- Turnermotorsport 24lb Injectors
- Chuck & Stickley chip for (s50b30 US)
- 3.5" HFM (from 540i/740i)
- Custom catback
The rest is stock. Stock obd2 manifolds, stock obd2 midpipes, stock clutch and I pass emissions. =P
First run: Was running lean and hot for some reason when my cousin did a 3rd gear pull. Only made 215-225whp/210-15wtq (don't really remember).
Second run: I decided to do the dyno pull. 4th gear pull with a/f ratios around 12.9 - 12.3 but temp was still very hot. Only made 225-230whp/210-220wtq (don't really remember).
Conclusion, pretty good numbers if my memory serves me correct (i need those graphs lol I might be wrong on the numbers). Could be better if conditions were slightly more ideal but I will redyno soon with a fan to keep my motor cool as it was nearing the RED area on my temp gauge as we were dyno'ing. My teacher who's been working as a dyno tuning teacher for over 20 years says I should be able to squeeze slightly more numbers with proper temps and running rich.
He told me running hot and lean = power. And running cooler and rich = power. Running hot, and rich = less power. Running cooler and lean = less power. < --- Don't know if there's much truth to that.
But yea, enough with my low numbers. Could it be my car? Could it be the dynojet? Who knows. That's what it is.
If e30polak (Chris) doesn't mind speaking, he will tell you himself that these numbers don't do our race justice considering he put down 235whp/229wtq. =P
