According to Yank's website the TT2600 will increase 0 - 60mph times .3 to .4 seconds. My truck went 9.873 @ 72.4mph in the 1/8th and 15.22 @ 90.9mph in the 1/4. Would it be save to estimate that with the TT2600 the 1/8th mile time be around 9.5x and 1/4 mile times would be around 14.8x.....assuming good traction and similar weather conditions?

 

So far with goin from my stock unit to the yank TT2600 i only dropped a half of a tenth in the quarter.....if i go to the track tomorrow while weather is cool maybe i will see a differance..

 

I dropped .3 in the 1/8th with Dacco 2300-2500 stall and Transgo shift kit, went from 9.80 best to a 9.46.

 

A half a tenth in the quarter doesn't sound right....did you get a best with the stock unit while temps were cool and ran it again with the Yank in hot weather? What track are you planning to go to?

A friend of mine just built a very mild 383 for his 98 Ext Cab and put a STS turbo @ 6psi. He is still working on a few issues with it but he is planning to give it a try tomorrow night at State Capitol so I'm going to try to head that way also.

 

i was told with my 3200 to expect about 5 tenths in the quarter if you can get decent traction...you should see between 3 and 4
