But if you figure 2 - 3 200's vs. 1 Turbo 400 that will last... Obviously the Turbo 400 will have less weight. |

To the OP.......here is a article that will interest you.
Overdrive Swap / 200-4R Overdrive in place of a Turbo 400 https://www.hotrod.com/articles/ccrp...smission-swap/ As you probably are aware depending on the power/torque level of your situation the 200-4R in stock form can be a hand grenade. That said, many have found and fixed all the weak points in this trans. And they can and do work fine. I personally agree with using a nonlockup torque converter for performance applications based on personal experience. And the obvious, building a strong 200-4R does not come cheap. https://www.hotrod.com/articles/ccrp...mission-build/ . . .

thank you
1) weight - less hp to pull
2) parasitic loss - less hp to turn |

LOL!
C'mon Tom... Really? Don't deal with a guy that has been in the game a lot longer than 99% of the people on this forum and 95% of the builders in the field? LOL! |

FWIW, comparing HD transmissions (T400 and 4L80E) vs light duty transmissions, and parasitic loss from Jake, of Jakes Performance. He specializes in T400s and 4L80Es which are pretty much identical internally as far as direct internal parts interchangeability. He states that the 2 HD transmissions only rob about .05 seconds over the lighter duty in a 10 second car, below that ET the loss is even less. This quote is taken from his frequently asked questions concerning parasitic loss. Of course either of the HD transmissions weigh more, because of the mass involved in making them strong in the original design.

That is not what he said. First, there are TWO Art Carrs. Second, the real Art Carr wasn't too bright, selling his name and all. Third, CK and Jake are at the top now. I get it, you really like Art Carr. He built you a billet everything 700R4. But the whole "dyno tested to 900 hp" rhetoric is something a circusmaster might hawk.

He said that has to do with core availability. In business, you go where the demand is. If things ever slow down for him, I expect he'd build another 200-4R, IF you supply a good core.

And I do have a good 200 4R core, but just as Jake says, the reliability is the driving factor, especially on a street, or a street and strip car. So unless you're going for a record, which I'm not, I'll be using a 4L80E, in my own car, anyone else can spend their money as they see fit on their cars.....

It appears the OP has had his questions answered, so I'll close it before this goes the way of every other 200 R4 discussion.
