do TC's kill the top end?
do TC's kill the top end? I know that in a quarter mile the TC runs great. What i would like to know is do they kill the top end performance. No i am not talking about dyno's i am talking about on the street. lets say in a highway race or roll race would the TC be an advantage, disadvantage, or no effect?

That is a bit of a loaded question. Meaning, to know your specific combination would be useful. For example, if you have a power adder then I would say that a high stall or loose converter is not going to get you where you want to be. But if you have a Heads and Cam combination with a little gear and some sticky tires... then yea you would definately benfit from a converter say in the 3,200 - 3,800 rpm range.
If your car is stock, I would ask what upgrades are you planning in the future... short term and long term. Because a converter should be considered to be very combination specific. if it is stock, and going to stay stock I would say that a converter that had a stall in the 2,800 - 3,200 rpm range would be ideal for a daily driver and would yield the benfits you are looking for.
Hope that helps!

I already have a VIG 3200. I will soon have H?C. I already know my acceleration is much faster but it feals kind of dead on the top end. Does a TC loose top end performance? IE roll racing from 60mph.

Stock gear?
Ordinarilly not. A converter is going to allow your engine to hang in the power band, up on the power curve longer. Usually when one slows or runs out of legs on the big end it is due to the Heads cam combo or the rear axle gear. If it is a stock gear then you simply are not making enough power.

A good designed (meaning a good package set up) verter should not loose top end mile an hour. In fact, every car I have taken the stock one out of and put the correct power band stall has gained a few mile an hour. Extension sure helps out the cammed cars! Your PI3200 has a good flash and OK extension (not great for overall NA application) but is a lot better than a stock converter. That drop off in power is most likely due to the converter gaining a lot down low in the rpms and not being able to add torque higher in the rpm band. Nature of the beast! If you went back to stock converter the whole rpm band would feel slower and the top end would then feel normal...

and based on what jimbob is saying is that even though i feel like i am loosing performance it is only based on the fact that i gained so much down low.
am i understanding this correctly?
TC's do not loose high end performance?
Correct a good quality efficent converter will not loose atthe top and more than makes up at the bottom, More than likley you are just not used to the feel of it because it seems so strong now in the bottom
