For those racers on the west side of the country, our windmill has sort of become our theme showpiece. We won Banned / Dangerous Technology at Reno with our windmill powered supercharger. For Thunderhill, we have stepped it up a notch.
May I present, WindCharger 2.0
It quite simple really, the windmill spins the auto-tranny flexplate, which spins the starter gear attached to the exhaust side of a 14L semi-truck turbo. What could possibly go wrong?

Absolutely spectacular!

I like it... but I'd feel better (and be a little more sure it might get past tech) if it had some kind of shroud around it.

The fan blades are made out of HVAC ducting, so they have 0 weight. Our last windmill was actually much larger, but made a lot less torque. It's noisy, but extremely solid.

Severed limbs waiting to happen! I like it!

Holy big turbo Batman! Cool!

Yeah, it's not the weight that worries me, it's the fact they they are sheet metal and thus sharp enough to slice flesh. Even if they stay attached to the car, in just the wrong situation... somebody could get shredded!
Since the intent here isn't to REALLY make something functional, why not make the fan blades out of something flexible that can't kill someone?

Well they don't start spinning until about 40 mph.. so I guess if a corner worker decides to attempt to hurdle our car.. yeah, it might hurt.
Since when is Lemons sane? It stops spinning if you hit under 40mph. Our old plastic fan blades wouldn't spin it.. we tried

After looking at your sig, it's clear you have bigger problems than worrying about our theme. Like figuring out how to make a car run reliably.

Hell if it can't kill you what's the use in having it on your car. Case and point the Metro gnomes with their chain drive motor.

Will this be featured in the upcoming "Saw" movie?
Nice upgrade! See you at T-Hill!

While the chain drive on our car seems scary it's not what make our car dangerous. It's our drivers that make the Gnome a terror on the track. Anyhow, I think that setup you have there is pretty great. I am a bit worried that a heavy thing like that could break free and hit another car though. How about a leash made from nylon webbing just in case?

If you guys keep this up you'll start making boost with these things.....and yes we were impressed at Reno..

Our used Harbor Freight boost gauge indicates about 1psi at about 65 mph... We havent had it up to race-speeds yet.
The Nylon strap is a pretty good idea... although there is enough hardware holding this thing down now, that I would be extremely impressed if it moved more than an inch in each direction.

That death trap has a 0% chance of getting on the track.
Fair warning and all...

Yep that should do it!![]()

As unfair as you might think it is, the TECH (i.e. safety inspectors) can't accept bribes.
But, your death trap has a 100% of making it through BS.

really? you need to talk to the guys at the new england race then. we had to go scramble for some more liquor to go through bs. didn't bother us, figured they should share in the wealth too

Oh hell yes! What could possibly go wrong, I ask you?

We also had to cough up some of our contingency cash in the tech line at Stafford. The cage guy caught sight of a wallet being readied for BS and started mumbling about tubing that looked "a bit thin". It took us a minute to figure out what he was trying to do because we assumed tech was a legitimate operation.
That was $58 less in the judges' pockets.

Reminds me I need to put Lexan in the gaping, debris swallowing, neck-severing hole that prior to Reno was home to our windshield. I think you guys are well on your way to inventing a perpetual motion machine.
