Clutchless tranny in S/S?

[SuperStockDodge]

Well heck, maybe it can be revised to "clutch cars" prohibited and not even have a manual transmission/clutch, flywheel, flywheel shield rule in section 6 of the NHRA bible and all the manual transmission cars will have have no choice other than to run a slush pump, since hardly anyone (not everyone) wants to race a stick car like it is intended to be driven in Super Stock, as well as Stock Eliminator.

I don,t think anyone has said you will have to run clutchless. Pretty sure you can still run a column shift.

Yeah,

I also heard they were going to allow neutral stars for automatics but the starter was going to be in the tower.

i agree with x-techman and superstock dodge, all a clutchless is is an over-priced auto for people too cordinationally challenged to clutch and shift at the same time. i think they should install a little camera on the roll cage and make sure everyone clutches when they shift. worked at are local strip. we have always clutched and shifted in a conventional manor at all strips where cluthless is prohibited. in testing, running a true cluthless trans we picked up .09. i have seen uncordinated people pick up as much as .25 with true clutchless. i have seen superstock dodge run at k.c. and he does use the clutch as we did. he did a damn good job also. hey, we were the cobalt parked next to you guys.

This issue was brought up for a vote by the NHRA S/SS committee at Pomona and did not pass. The rule will be inforced as written for now is what I was told.

How many people that are talking about clutchless trans being so much easier to drive have ever drove one or even know how they operate? We are talking about Jerico,G-force and Liberty right, if you are using manual shifter (no air etc.) the clutchless is no easier to drive than the clutch versions,if anything the clutchless is slightly harder due to not being able to keep in gear if off throttle or if you blow tires off.You think shifting
without clutch came about since Jericos or G-forces,or anyother face plate trans,people shifted old crashboxes(synchronizers took out every other dog took off gear)and pro
shifted gears without the clutch,just can't do it many times. face plates made it to where
you can do it for 100's of passes.
Anybody that is good in a stick car will tell you shifting is the easy part with or without
clutch or clutchless doesn't matter.
The only ''helpers'' I like and use are high side rev limiter and line loc switch released
with clutch and can do without if want to.
People that worry about losing to sticks are the same ones that would worry about
a quadrapalegic having a advantage in a fist fight.
I would be ashamed to have a RPM activated shifter to make one gear change.

Very well said

I was told there is no advantage of running a true "clutchless" trans compared to clutch (i.e. GForce GF-4R or Jerico DR4). The primary advantages with the DR4 over a T-5 is durability and quicker shift action. I learned to "speedshift" a stick long before switching to a Jerico. And while you can shift the DR4 without kicking the clutch, it's usually at the expense of "out of power band" shift points or a fully adjustable clutch like Soft-loc or Advanced is used.

I have a friend who purchased an ex Larry Morgan Stratus complete with power train (Liberty) which turned out to be a nightmare. He found that clutch setup was very critical..and difficult to master. It made the difference between tire shake or destroying clutch discs @ $400 per set. Tire shake ended up equating to chipped gears @ $500 per repair. Shift points also played a part in keeping it in one piece. The first 2 outings costed $1200 with only 5 passes. So the Liberty went bye-bye in favor of an automatic.

Lenco is perhaps the easiest to operate...but it's a power robber especially with lower HP engines, requires many adjustments, and stupid expensive.

In the end clutchless transmissions (might) offer a couple hundredths, but at a ridiculous cost.

i think every combination differs. i have personally not seen anyone break a g-force cluthless at are local track, and they all picked up when changing from a trans that is clutched between gears and a true clutchless. we only know what it did for us. not changing any thing in the clutch from one set-up to the other we picked up .09 on second pass, and according to the computer we missed the shift points by a few hundred rpm. we just ran a single disk soft lok.
