[E-Tech]

Working hard on this. Been putting this project off for way too long.
Should be finish for the worlds finals for viewing.
More pic's to come in the next few days
Just a scrap piece of material to start with

Not looking for any of your "secrets" but what do you feel is gonna set your cylinder apart from the rest?

1-Cheapest price for a Billet.
2-I just try to make thing better that's my nature!

what are your time frames for testing and then production?

 

[E-Tech]

Here is more work on the test piece. In 5 axis mode! Check out the undercut. Good cooling flow.

what are hour time frames for testing and then production?

Sleeves and pistons are 4-6 weeks. Still there is testing on the dyno and then field 2-3 months.

Here is some more. working on head this week.

What's with the zip-tie? And what's going on with the front exhaust area ? Looks like a chunk is missing

 

[waxhead]

It looks awesome for sure. What makes this different from all the other cylinders out there. Im not saying dont do it or trying to slag on your product just wondering why i should buy this one versus another

Wax I asked the same thing, then I saw him and the cylinder at WF's. This is an opinion I'm about to state and in no way represents the company. It looks like even cooling for both cylinders has been addressed, the roofs of the transfer ports have some extra angles in them, exhaust port angle is a little different than the current available cylinders. Nothing super radical but definitely worth a look and consideration for anyone's next build. He also told me his domes would be stepped like the old Cool Design domes which doesn't hurt cooling at all with the added surface area. Hope this helps.

 

[E-Tech]

The zip tie is just to show there is flow under the bolt holes. The chunk is my math mistake. Just a prototype.

The dome is also has coolant all around the dome accept where the boltholes are. Also the flow from cylinder into the head is restricted in some areas to make sure the cylinder and head are evenly cooled, This allows for maximum compression and squish without detonation = power and reliability.

did this die?

I am not a representative of ET in any way but Art is working on a finished product that will meet both his performance, quality and price expectations. He is not a man to hype his stuff, rather let it speak for itself like his chargers do.

Just finished head!
