Injected nitro motors are not as consistant the blown cars. Yes when they run correctly (not dropping cyls) I think they have a performance advantage over the blown cars. I know there is a injected nirto hydro that runs TFH. They really have never made a good pass with it, and struggle alot. I think you might have the same proplem with that motor combo in a flatbottom. Plus I think it costs more $$ to field an injected nitro race operation than a blown alcohol deal. And as we all know there isn't alot of guys that have extra money to switch motors deals for the same performance they can get with an existing package. In my opinion, I think we should bring back the TFF. Now with the invention of the saftey capsual we wouldn't have very many, if any at all, fatalities. I am sure there will be accidents in a TFF class, but no more than in TFH, and no one seems to be complaining about that class (TFH) being too dangerous, and outlawing it. Just my $.02
