TQ Damper ? . . . one way or two?

nothingclever · 2008-10-20 12:29:33

Hey can someone who has a torque damper answer me this: Is the damper a one way (damps only in one direction) or two way? Do they return to fully extended when released? Thx for any input, just tryin to be cheap and make my own, but I need to know the type of damper first

My RevAuto TD is pretty much solid..I suppose it dampens in both directions though...let someone with more knowledge answer that for you though.

I do know one guy on here made a cheap torque damper from a 240sx ebay TD...

the tq dampers are meant to be installed in one particular direction. for ex. the rev auto, the damper is suppose to be closest to the firewall.

However, sense there are only 2 forces that would act on the damper i suppose it could technically dampen in either direction.

Yeah I can get industrial dampers for like $20 lol but they are one way, I figure the motor is really only going to kick in one direction, right? All I need to fab is some brackets

kktohot · 2008-10-20 12:44:51

you can buy rev auto's brackets from them pretty cheap

nothingclever · 2008-10-20 12:46:17

yeah, but it's also the fun of makin something. and free is even cheaper than cheap lol

but how much can you get the dampers for? and can you get them to sell them?

Yeah maybe. They are like $23 I think (?) but I would get one for myself to check it out before I started selling them to ppl, they might suck for all I know. I've really only got part # and specs to go off of, they don't really even show a pic. Just tryin not to spend $$ right now, but can't fight the car project urge

would you be able to link me or PM me the specs by chance? Id like to check em out.

We use a site you gotta log onto which I can't really, but I was looking at those and also P/N 6521k53 from McMaster-Carr (http://www.mcmaster.com/) that might work too but I don't know about the ball joint at the end, might snap over time.

you also could get two of them and hook 2nd one up in reverse, so you end up with dampening both ways.

(lawls) thats not a bad idea. I should just put them all over my engine bay

and yes McMaster is the shit

kktohot · 2008-10-20 15:45:47

rev auto has the ball joint...on theres its needed because its not exactly 90* to the firewall.

however I think you should get the 575 Part force,lbs comp for 65$.....but that may be too much for the aluminum head

nismored · 2008-10-20 23:36:47

I dont think you would need to dampen a 575 lb force from a rotational movement of the motor. I think the 117 lb damper would most likely be durable enough. The ones with the ball joint are something you would put on a hood or tailgate. It just keeps the item from slamming up or being force really hard opened.

nismored · 2008-10-20 23:43:45

Well here is my logic. When you floor the motor under no load...car not moving and you are looking under the engine bay. It is a rapid rotation of the motor. If you were to pick a point on the motor, when you floor it, that point would move maybe 2-3 cm....thats a rough estimate. So you need to dampen 3 cm of movement which happens in a matter of less than a second. I guess the only concern would be is if it is a viscous damper and it is designed for a lower load then it could blow out. I still think the 117 would be fine.

You can just install 2 of them, one in each direction
oh fuck someone stole my idea!!!! I better read the whole thing before posting!
