Default Lenco now offering overdrive unit.

I have talked with Gary Sumek at Lenco Racing over several weeks.
They can now offer a permanent overdrive to the back end of a Lenco CS2 racing system. The unit runs about $2600.
It comes between 1:1.56 and 1:1.31 overdrive.

The 1:1.56 overdrive is a 0.64 ratio this would really help a landspeed racer or high speed drag racer at the top end.

Call me if you have any questions, I have already asked him a lot of them.
It is a non-standard part and he will try to sell you a transwarp motor adapter plate and a full system as well. It is basically the reverse of the underdrive "gear reducer" they sell.

He would only put it on the back of a Lenco CS2 without paying for full development costs. So it is a little bit of a big gulp to take. But if you are into building custom plates and shafts this could be for you.

So they consider it standard when its on the back of their CS2 transmission and it costs $2600? Putting it directly on a transwarp (like DC plasma's Gearvendor) is what costs extra?

By permanent do you mean it is not switchable? I guess what I mean is can it be used to make a 2 reduction lenco into a 2 reduction+2od=4speed?

Tried to make that not confusing. Hope it worked.

$2600, Yes, pricey, eh? Building the TWarp adapter costs $450 extra.
Permanent, meaning it's always active, no switching it on or off like GV.

My solution to this problem is in my Assualt&Battery build thread. Two cases, four speeds. plus reverse and neutral. Used parts about $3200.

Does that mean it will transmit torque in both directions and both speeds? Thinking Regenerative Braking.

Edit: I misunderstood. This is a fixed gear, not a shiftable overdrive, so I wonder what advantage it has.
