The converter has a one way clutch. Being a 9.5 inch unit it is made from a front wheel drive GM converter. The sonnax kit comes with the race to use the stock roller clutch, for low power cars it will work but really needs some lubrication issues fixed to survive much abuse. Mechanical diode and sprag style assemblies are available. I include them on some models and make them optional on others. What matters is the lockup system. A carbon clutch alone does not make a good converter. These units with stock fwd gm lockup pistons and a ring welded to the front cover are all too common. This company I am familiar with they are the ebay advertisers with too good to be true statements. For now I don't know much about their products so break one and we will see how it goes.....It takes about 6-8 hours to properly assemble any decent race converter, at minimum. I will not mig weld inside a converter because of the slag getting use in the unit, but it does make the process much faster. Unless someone is giving this place their parts for free or they are holding people at gunpoint to do the work they cannot be doing it right for the money. In time we will find out what the deal is. I barely scrape by charging what I charge, are these people just filthy rich and want to give away the product? All the other companies prices are higher than mine but this one is much lower. It doesn't make sense....
Maybe I am incorrect but I believe ReVmax is out of Arizona. Are they are sneaking illegals over to build TQ's for less? Dingy should call the Authorities!
I have to admit that years ago Dingy revolutionized the torque converter industry.
and I were witnesses to Dingy's business start-up... He was once a friend of ours before he sold his soul and went to the Darkside...
DingyDog was working at a transmission shop. I took plenty of pictures for him... some he still uses... He decided to sneak in there at night to build and sell TQ's with his bosses tooling and possibly material. For some reason his boss must have asked for a cut. Oh NO!!!! How dare he!!! Dingy turned into "Greedy Gertrude" and refused. So he was fired!
Dingy decided to start his own business.
Since Dingy's old boss changed the locks he had to find a contractor to build his torque converters.
reported to me how Dingy traveled around the country looking for TQ shops to build to his specifications.
One time Dingy called me. He wanted me to get me to have one of my draftsmen to draw what he called a billet TQ cover. It was not machined out of aircraft aluminum, instead it was stamped. I could not get my name something that I consider false.
In the end, Dingy decided to sell his soul and join with what
used to call the Darkside a/k/a tccoa sales & marketing elite. They set him up with a Muscle Mustang Fast Fords Article and something to get started.
The truth be told, the reason Dingy's TQ are more expensive because they have double mark-up's on them. First the cost and profit for the contractor to make them plus Dingy's profit.
Suffice to say that it seems there are many TQ companies that now build a performance torque converter. Here are some assumptions as to why there are so many TQ companies are out there:
- Dingy may not have had a Non Disclosure Agreement with the shops. So they took his design.
- Others simply cracked open and reverse engineered his TQ's.
- He is a Greedy Gertrude and may have pissed off several shops and had multiple suppliers, some of which became competitors...
Who knows... maybe... just maybe... Revmax makes DingyDog Torque Converters?
