G-Power vs ESS dilema

Be advised that previous kits required methanol (?) injection. I do not know if this is still the case.

Here is an ESS VT2-625 & Active Autowerke level 2 super charger kits.
Both kits were installed on both cars at the same time.

Same dyno, same time of day both on 91 pump gas.
Both cars have same exhaust setup "factory cats and middle secion" different brand rear mufflers.

The Active kit puts down more power and on the street it pulls way harder and performs better then the ESS kit.

Dyno used is a low reading Dyno Dynamics.
For Dyno Jet you can add around 18% but you can see the difference in power between the 2 here

I have an Active Autowerks Gen 1 Stage 2 with Meth injection kit+ Air to air intercooler upgrade, with custom Carbon fiber Manifold, beautiful kit and fast as Fuck!
With the Methanol injection and the Air to air intercooler it can be faster than the one mentioned.

All boxed up. looking for $6.5k + shipping.

Why did you remove it?

The methanol upgrade is next.
Clutches are being upgraded along with some better cooling (engine oil and DCT) then methanol

As an owner of a ESS kit - I'd steer you to Harrop.

any details on why?

How would you also evaluate a reliability of the s65 engine under ESS Supercharger if used on the track?

Think it's important to note that these are two fundamentally different supercharger systems. Even besides the difference in blowers (ESS uses a Vortech, while G-Power uses the ASA), there are substantial differences in how they cool ambient air: ESS uses Air/Water (just like VF), while GPower is Air/Air (similar to AA and Evolve).

When you say tracking, if you're talking a track with turns (and not just 1/4 mile or airstrip events), the Air/Air setup should be more beneficial. While the Air/Water will give you better IAT suppression, once the water temp exceeds thermal efficiency it'll be difficult to keep them from increasing. Yes, you can pull over and pour ice in the water tank, but Air/Air should be more efficient over a prolonged period.
