This is the link that should have been sent for the 12v system.

Looks perfect for a 12 Volt starter alternator.
The big questions are; what does it cost and what does
it weigh? The liquid cooling is good.

Paul Lamar

The website states temp should not exceed 105C/221F.
Isn't that a bit cooler than we want the engine?
C. Smith

That is about right. What bothers me is what happens to your starter alternator
if the temp exceeds 105C. This spec. seems a bit marginal.

BTW for those people that have not heard the rational for these systems
take a look at these jpgs.

I found it interesting that Government Motors discontinued them and
reconfirms the logic that unless a fuel saving device, like a hybrid
or starter generator clearly pays for it self in fuel savings, people
will not buy it. I wonder how well they are selling in Europe
where gas is $5 to $7 a gallon and global warming hysteria is
more prevalent.

Here's the reply back from SpeedStart.  Not encouraging for aircraft with unit weight at 11.8 kg (26 lbs).

Greg,

Can you provide any more details about your intended application and timing both of which could affect project/unit costs.

Our SpeedStart product is currently at the production intent design stage with design validation testing of the final design underway and high volume production targeted at Q4 2012. We are producing SpeedStart in batches ahead of that time.

The unit weighs 11.8kg and has been designed for 12V and 24V use, though calibration for 24V has not yet been scheduled.

We have supported one design study for a gear drive installation and do not see a reason why it would not work, though we would need more information before commenting further.
