Challenge: I think I have the world's fastest 308

I'm probably at 5 or 6 seconds I'd guess, on the slow side. I dont have the "boosters" and I havent yet installed Birdmans fuseblocks (which I'll get to as a winter project I guess). Mine appear to do fine for the first 3/4, and slow up when they near the top. That indicates that maybe I have the "old hard grease" problem rather than an electrical probrem.

So, I'm out of the race.......

Anyone else....

That's pretty speedy.... my driver's side takes about 3 seconds... the passenger side about 5.

 

The logical question is - Did you do anything special to make your windows so fast ? (mine are about 6 sec)

 

#20405 is pretty fast...I'll take your challege!

Keep the motor grease fluid, a little spray silcone on the window channels....that's all I have done, since buying that one.....

 

A pair of new HD motors would help, along with lube for the pullys and new felt channels.

I don't even have a car yet but am tempted to buy them anyway

Mine takes 2.6 days one way then another 2.6 days back up

 

only 2.6 days?

 

Sorry but I've got you all beat. My 308 goes 2,670 feet per second and its made by Winchester! sorry I had to do it! Joe

 

ummm... thats 308 not POINT 308.... or 30-06 (or 30.06)...... LOL

Strange what you find on the web......

Interestingly, that board also appears to be "f-chat".....

Strange little world.

If my calculations are correct, when this baby hits 88 MPH you're going to see some serious sh*t!

Even FASTER with golden wheels! LOL!

 

Wheels? Who needs wheels. I've got the hover conversion.

 

"Roads? Where we're going we don't need roads!"

 

Aaaah, I remember when mine were that fast... good times, good times.... Now mine are running about 8 months and counting. Hey, it's on my list of things to do!

 

Fellows,

You can shave off a few tenths by adding a 4 degree taper to the interior side of the glass and another tenth by cutting a tiny (2mm) V channel 5mm down from the top on the exterior of the glass...this improves laminar flow by about 22%.

Replacing the track felt with Wight cotton felt made from the coats of free range sheep adds another handful of tenths...it's pricey, but this is racing, right?

Nitriding the assemblies also makes the moving parts much more resistant to wear as well as more amenable to lubrication with today's synthetic lubricants. Selecting a good 10 or 12 turn electric racing motor will reduce your times by quite a huge amount, but often require stronger lift gear and tension wires ass well as the addition of a properly sized heat sink for the decelerator unit and quite possibly will require the installation of an exterior NACA duct to cool the works.

 

+1 maybe next spring for me

 

Posted my windows video on Yahoo Ferrari Tech forum after I rewired both doors. Memory serves it being 2 seconds down and 3 up. As I don't have a stopwatch I will defer the win to you.

Gravity does help, down definitely being quite fast. In addition to bringing fused 12V into the door and adding 2 relays (per side), I also spring loaded the idler pulley and put a limit switch on the bottom.

Ain't it great having zippy winders!

 

LOL LOL LOL!!!!!!!!!

 

What windows? They move??

 

I propose a bracket system. That way we could have more interesting racing with better results. I'm not sure this is fair for us guys with original window motors (ie no boosters, grooves, grease, etc). We should not be in the same bracket with guys running sub 4's or even sub 1 days. Just trying to keep it fair...

LOL! One of the 'quirks' of my car is that drivers window will only go fully up if the door's closed whereas passenger side will only go fully up with door opened. Both in about the 2.4 days vicinity...
