I made the switch from 50/50 to 100% meth. So I added an extra nozzle to make sure it can spray enough meth. Thank god I had that extra bung welded on when I did.
I've also spent a lot of time tuning in the past week. I like to use Virtual Dyno to help visualize and quantify any changes that I make to the tune.
Here's where the car was BEFORE installing the Aquamist system:
- 326hp / 364tq
- 22psi across the board
- 11.8 AFR
- Max timing of 13* at redline
And here's where it's at now:
- 393hp / 385tq
- 0.8mm+0.9mm nozzles, 100% meth
- 22psi to 4500rpm, 26psi from 5500rpm to redline
- 11.8 AFR (NOTE: I had to scale down the open looop mass airflow in order to achieve targeted AFR)
- Max timing of 19.5* at redline
As far as cooling the charge air temps, here is a comparison just to illustrate how the meth is helping.
I must say that I am very pleased with the results!!!
