Competition really dumb question Hee hee

OK way out in left field here. what kind of transmisions do NHRA stock cars use. you know, the "door slammers". i know they are manuals.



i was watching drag racing on TV the other day and they showed a race from inside the car. the driver just rocked the shifter front to rear for each gear change. as in; start out pulling back, push forward, pull back and so on. no gate just straight each time. and just the one lever. they used to have like four or five levers they would pull for each gear.



I want one in my truck. running 6's obviously they can handle the HP. can i handle the price tag?

 

[Morphious]

it's called a ratchet shifter... and don't work with a toploader to my knowledge.



Morph.

I've been out of racing a lil while but that shifter is called a V-gate shifter. A company called long manufacured them. As for transmissions, They are Liberies at around 5 grand a pop and a clutch that goes for 3000-4000 * edit... the 4-5 rodded shifters where lenco transmissions they were before the Liberties

 

[F8LDOSE]

top manual transmission companies are Jerico, G-Force, and Lenco ... . they are 4 speeds and 5 speeds.

In-line shifter. Husrt made them for a while, maybe they still do? My cousin had one in a 67 fastback. It was cool, but a PITA to keep adjusted.

thanks gang, i'm after the whole shooting match. not just the shifter.



when you compare what i will have to spend for an automatic that might hold up. this looks like the next best thing. I'm sure Peter could build me a clutch for it



just wonder what the longevity of one of these units is?



what about Doug Nash, they still around?

 

[340Mark]

Doug Nash inc is long gone. These units handle high horsepower like 1400 at 9500 rpm. I can't say what there torque capability is. Cool idea though. By the way they are not synchronized. Each up shift disengages the previous gear.

Lenco's. I like those the best. Nothing like having someone get in your ride and not have a clue what to do.

 

[willyslover]

Doug Nash is now the Richmond transmission. . they bought out Doug Nash several years back



the last Nash I was involved with would bind up about 50% of the time with high torque loads

 

[SWalker1]

I spent 3k+ on my DTT auto , the best money I ever spent ! To-date I haven`t been beat by a standard. Can`t imagine spending a bunch on a standard to be out-pulled or out-run by an auto! I`m not saying they`re for everybody, but I sure mine.

 

[HEMI®Dart]

Here ya go Todd. This trans would hold the torque. (maybe)

Todd...

The transmission in question as already answered is either a Lenco or a G-force. While Jericho is widely used in comp eliminator and stock/super stock they are not used much in a pro stock application. Reason being you may make a gear change with the Lenco/G-force by splitting the transmission at the track and adding a new section while the Jericho has to be a complete change as its easier to do that then disassemble the whole assembly to make the change.



Now the shifter in question. .

While in the old days a V-gate was the norm way to many problems arose with them binding and jamming in gear causing either breakage or a round loss. Most have been abandoned a long time ago. You will find most P/S teams using a design of their own or Long shifter from here in Pa right near me. They are simply the best manufactured piece today for a racing application. They are a small family owned company who gained their fame by developing a shifter for the Nascar boys to roadrace with. Most of the FAST comp cars all use them along with the quicker stocker and superstocker guys. They are not cheap but quality is what you get. I do know someone here who has inquired with them and was turned down for any for our trucks.



Now for my own insight here from my experience. .

A Lenco,G-force are not designed to be downshifted and are a PIA to street drive. My old pro street car had a Lenco in it at one time and was sold due to its difficulty to drive sanely. At WOT it or my old Nash were hard to beat. The Jericho's can be made street user friendly but are not cheap. I am not sure how they would stand up behind the massive amount of torque our trucks can dish out. Now if a Lenco style is what you seek check with Jeffco as they make a Lenco style that can be street driven... ... Andy



P. S. -Upon edit I had mistakenly forgot completely about Bruno and Liberty both of who make a good planetary style transmission. Now will they hold up in a diesel application,who knows,street friendly nope,just figured I'd better add them.

Top fuelers don't even use a transmission, they use a multiple stage clutch pack( don't ask how it works because I'm not sure how it works). they can't find a transmission that can hold 4-5K horsepower:--)

 

[78repowerwagon]

Once the clutch is released, It it not touched untill the end of the track. Hold her flat on the floor and jam gears without the use of the clutch, is that hard on stuff

One of my projects to do some day when I get all caught up is to build a shifter using linear actuaters to make the throws on the transmission and two micro-switches, one at either end of the throw to signal the shift. Another switch (like a 2 speed rearend switch on the stick) would tell it whether you wanted to upshift or downshift.



To do this on a toploader would require your components be sitting on the transmission hump.
