Anyone running a Lenco ST1200?

[DanBadger]

Transmissions for 4-digit power are new to me.  Feeling my way blindly through the maze of mega-bucks trannys for big boys, the answer I have come up with for 1200 crank HP is the Lenco ST1200.  I talked to the tech guy named David at Lenco, and he recommended the 4-speed version with upgraded bearings, which would end up costing right at $5500.  That's a real wad of cash to me, and I would appreciate some input from the guys who have been there and done that.  The application is 1200 HP, 3600lb, seeing about 1000 miles of street use and 2 or 3 land speed events a year.  I was first leaning toward RPM's T-56 Magnum, but the ST1200 is only a couple hundred bucks more, is cheaper and easier to service, and is many times cooler.

Thanks in advance!

i would run the regular lenco with a breather not the st1200. you're maxing out the trans with a 1200. the reg.lenco can handle much more and can still be driven. seen it done. ask dave about where the breather would go and then start looking on racingjunk or in the digger.

Dave is of the opinion that the ST1200 is going to be fine at that power level, or more.  I have no objection going with a CS1, I am just attracted to a reverse and neutral, as well as the price break of the ST1200.  I'll look around for a used CS1 that will fit my needs, and if I track one down for the right price I will be right on it.  Thanks for the input.

Someone on the landspeedlist in the last week or so was posting that they were having trouble with the ST1200 they were running. They were having problems with either the bearings or the sprags. Maybe they will see your post and reply.

that all fine and dandy now while you're making 1200 hp. but you know as we all know that next year you're gonna want more power and you'll do something on your motor to make more power and oh wait ..........now i need another trans to handle the extra 350 hp i got from the nos. just get a cs1 and be done with it.
just my 2bits worth. that ST1200 was just a way for lenco to make a cheaper trans and sell them for the same price as a comp model. put a breather on the cs and you'll be fine.

The "room to grow" argument makes a good point- at that price level, I would much rather buy it one and never think about it again.  It looks like I can pick up a used 4-speed CS1 for around $3500, put another $750 in clutch packs and bearings, and have a transmission I won't have to worry about.  Any idea how much the reversers are for the CS series?  That's kind of an important chunk to me- streetability (and parkability) is a real requirement.

The more I talk to guys who have been there and think about it, the more I drift away from the "little brother" transmission.

98% of units sold have the reverser on them. Most racing organizations require them. I think they only make one reverser for all their models. Just make sure it has a neutral detent on the reverser.

Ah- based on the sample group of 2 that I have driven and 1 I have found for sale and looked deeper into, 2/3 did not have the reverser, so I assumed that they were not as popular as you suggest.  Chalk it up to my new-guy inexperience.  Thanks for all the help, guys.

LOL. you must have run across all the ones for boats. You should also ask on the CS1 if the gear sets are course or fine spline. Course gears are OK for LSR use but are the older Lenco gear sets for the CS1. Fine spline is what they now make. Also you can buy two two speeds and lenco can put them together as a three speed, but the cases have to be machined. Some of the ins and outs I have learned over the years dealing with Lenco.

I had some two speeds I had them make into three speeds and bought the parts necessary to run them either with or without the reverser.
