Is there any opposition to a th400?
I don't think there is a performance advantage at all. I disagree with clay above about launching harder with a 400. Pretty sure John P over in tsm doesn't hold back on his 200 by the looks of his launches.
A th400 will not make you faster, weighs more, takes more power to turn, has the same converter selection. So nothing there.
Heard someone say that there has not been a 200 failure that caused a ths racer to sit out. There goes the theory of a 400 being an advantage in durability. So no gain there.
Only advantage is the cost. It is cheaper to build a 400. That in itself should be good for the class.
The gain to the class would be to let people in that may be legal everywhere else but the trans. I have a 400 now and gaurantee I will show up to at least one ths race this year if a 400 is allowed. I've already made my mind up that I'm not going back to a 200. I would like to know soon which way this is going to go. I got some decisions to make on front suspension and if I'm putting ac back on the car.

Kevin, Doesn't a 400 have a 2.48 first gear compared to a 2.75 for a 200? Some would say that would be an advantage when working with cars that make a lot of torque like turbo engines tend to do. Before we get to carried away with that conversation, I know gear sets can be changed in either but will maintain that the majority of TRs out there are using the stock gear sets.
The important question to ask is, how many cars does a major rule change like this bring to the races? Do you know of very many cars that have 3x2 housing turbos with ac and turbo 400s?
