Is ESS really any cheaper

[larr12]

Is it me, or is the ESS kit just a vortec or paxton type head unit with the procharger mounting location? I remember a time when everyone complained that prochargers were breaking cranks due to the added stress from the head unit being mounted so far away. Now that his company comes around everyone forgets about it.

ESS belt/bracket setup is different than procharger.

but the supercharger is in the same spot

Correct. From what I read here, different belt position on the crankshaft damper and procharger use an additional pulley*.

one of the reasons i purchased the procharger carb legal kit was because the supercharger is in the same location as the vortech/paxton and was driven off the stock balancer. so it all depends on the kit

I already have a tuning device and injectors as a fbo… i can get a G2 with upgraded intercooler for less than $5k… that’s a bargain…

we can do a vortech and paxton which is a larger head unit for the same $ we are typcilaly a couple hundred less on our stage 2 and 400 less on our standard than the g3 which is more comparable kit

I have noticed posts being made about the G2 being the “smaller” head unit in comparison to competing systems base head units. Consequently, putting the G3 in place of the G2 as the comparable system. I just wanted to clear things up and make sure the facts are out there. And just for fun I decided to do a size comparison with two blowers I had sitting at the shop. One being the G2 and the other a V3si which are both the “base” head units in their respectable kits.

First, some performance specs as provided by both manufactures:

V3si

Max speed: 52,000
Max flow: 1,150 CFM
Max power: 775 (crank HP)
Discharge OD: 2.75”
Inlet OD: 3.5”
Inducer diameter 3.1” (78.1mm)

G2

Max speed: 57,000
Max flow: 1,300 CFM
Max power: 800+whp
Discharge OD: 2.75”
Inlet OD: 3.5”
Inducer diameter 3.2” (82mm)

Here are a few pictures of the two impellers and volutes for comparison. As you will see, the G2 doesn’t just have more capacity on paper, it is also physically larger in both inducer and volute size while remaining much smaller and lighter in overall physical size and weight. When spun to max RPM, we have seen over 900 whp with the proper supporting mods. We commonly see 800+ whp on standard setups.

In packages that contain the v3si, customers can opt for the v3si or v3jt or 2200sl in any of our kits at no charge. In our packages that contain a 2200sl or v3jt, customer can opt for a v3si at no charge

Would be kind of cool to see the same comparison stats added for the G3, Paxton 2200, Procharger P1SC, P1X and D1X.

Likely splitting hairs though... for me anyways, the inability to start the car in the winter with cold temps, without risking damage, would be a no-go for me... also oil slinger / lubrication / bearing longevity etc...

YMMV with where you reside and what you expect from your car.

The great thing about our kits is they are proven 8 second setups. Tried and true for over 10 years. here is a nice writeup on one of them.

I like facts through comparison measurements. ESS IS definitely, noticeably a more robust flowing turbine. Thanks
