Hi guys,

I plan to increase HP & TQ on my S65. Goal is to achieve 500 - 550 chp for my daily driver.

There are a lot of opportunities to achieve this:

supercharged:

ESS: seem to have a great scalable kit.
Gintani: works quite well, needs more psi to achieve power compared to ESS.
G-Power: reputation issue.
AA: looks good, but much more information would be needed.

In general, SC noise will be an issue.

na:

Various ECU tunes are available. Still no flash @ home capability.

- Use good gas.
- Intake upgrades will come down to use a high-flow intake air-filter.
- Midpipe seems to provide most power gains ( by deleting secondary catalysts only ).
- By deleting the primary catalysts you will gain another ~ +8 whp.
- Muffler upgrade will gain 3-5 whp, if any.
- ECU tunes / Black Boxes will be needed to support deleted or changed primary catalysts configurations.
- ECU tunes provide power gains as well.
- Power pulleys help.
- Water / water-meth configurations have still to be applied and to be tested. Compatibility to the knocking-system of the S65 ?

Now, start with bolt ons or go with a supercharger. You might have to go back to stock configuration for various reasons. Curious what you think about that.
