    torque specs i am building my motor and trans up to handle to boost for a hellion twin turbo system . do you think this will help me spool up for a better launch at the line. thanks jesse

    • Definitely. I'm going this same route and have been doing a lot of research on the subject. A 3000 to 3500 stall with a turbo system is gonna be awesome!

    Will this work with comp stage 2 cams and my factory transmission?

    What are the actual torque converter bolt pattern on my 03 Mustang GT ? I did some research and I found 2 different bolt pattern for 4r70w torque converters. The first one is 11.250 and the second 10.625 depending the flexplate and the year of the car. Will this TCI Street Fighter work on mine without any bolt pattern issue or I need to change my flexplate ?

    Will this converter require a custom tune

    • A custom tune is not required for the TCI Street Fighter 4R70W Lockup Torque Converter.

      Improved 60' time!

      Great performance gain. Improved my 60' time by 4 tenths. Locks up good on the street. One pin was a little off at installation and had to be ground slightly at the shop. TCI could have had a little better quality control, but it hasn't been an issue. I would recommend this highly; between the convertor and 4.10 gears I took of almost a second in the 1/8th with drag radials!

      TCI torque converter

      Great product. Hard to say about the performance gains due to me installing a TCI streetfighter transmission also. Great improvement over stock by far.
