Hey,

I was talking to level 10 a few weeks ago about getting a built transmission and they were telling me that when I dyno the car I'm killing the transmission.

They told me that one run on the dyno is equal to 25 1/4 mile runs, and that I'm hurting my transmission every time I dyno the car.

I know they have had a bad reputation on the forums, and people have had bad experiences with there valve bodies.

Is it true that dyno runs are bad for the transmission, or do they not know what they are talking about?

I don't know anything about this, and I'm sure someone will know. I just like to be on the safe side, I would rather not blow my transmission.

Thanks

a dyno simulates gunning it on the road, without hydrodynamic friction. i can't see how its any worse than a single highway run.

 

This thread = fail

 

I didn't think that a dyno run is bad for the car, but I figured I should ask because level 10 made it sound like the transmission would explode if I dynoed it.

 

I will say a two things regarding there comment....

1. When something has been done to your vehicle (engine related), would you rather have it tested and wosre case break on the street or in the shop on the dyno?

2. If you were having tuning done, would you tell your tuner to stop, just because he's making a lot of pulls to give you the best tune?

 

hydrodynamic

lol.

 

epic fail

 

It would only be like 3 pulls, I'm just on the TN re-flash.

I guess they just worry about me blowing my 5AT, probably over cautious.

 

If there an experienced tuner, then they should know went to get out of it. If your 5AT goes on the dyno, then it would have gone on the street.

I have been a shop while a car was being tuned for over 5 hours and nearly 60 pulls. Dynos are your friend, they make you feel all warm and happy inside when your car puts up good numbers...

 

Maybe Sam from GTM or Sharif from Forged or JT from Performance Factory can chime in... They are the ones that do the actually tuning. I mearly observe, and sit in trucks of 1200 WHP Supras to help get traction on the dyno....

 

A dyno tune revs your engine to redline in one gear.

A drag race revs your engine to redline in several gears.

How can a dyno run be harder on your car?

 

+1

not to mention the burn out, the brake wear from slowing down from high speeds.... your tech doesn't know what he's talking about.

 

I would have laughed in his face...

.

 

i would have also

 

well....yes and no....

obviously after doing extensive engine work on the car, from its stock parameters, a few dyno runs are needed to tune the car and make sure its all functioning properly. as mentioned prior, its obviously the safest and best way to test.

however, i tend to believe that people who constantly do dyno pulls with their cars aren't nesacarily "hurting" their cars....however, the car was designed to run under a constant load.....no dyno can simulate that 100%.
so you are putting unneeded stress/wear on the entire car, no matter how you look at it.


however, at the hands of a qualified tuner, i see no problems for tuning purposes.

 

I was told this over the phone I thought it was b.s. too, but I wanted to make sure. Probably wanted me to drop 4k on the built transmission.

 

You are putting unneeded stress/wear on the car by bolting on aftermarkets parts.

If people are worried about causing there car to not last as a long as it is suppose to, those people should NOT be putting aftermarket parts on there car. So saying dyno'ing the car is adding unneeded stress would be wrong, because the aftermarket part they put on to need it dyno'd/ tuned is unneeded stress also. People that are worried should stay stock!!! (Just my little two pennies)

 

To the OP. If you are extremely worried about your tranny though my suggestion to you would be that Stillen makes a pretty good tranny upgrade for the 5AT's.

 

Sounds to me that they don't have any confidence in their own work in building a transmission, so they tell you that it could blow on a Dyno. That way when it does blow, they can say that they warned you and it isn't covered under their warranty anymore. I'd find a new tranny builder.

 

Stillen is not the best.

I have been told spg or gtm.
