CenWaSS Posted April 7, 2009 Report Share Posted April 7, 2009 I've got a tbtc currently and recently installed a radix. My question to all you with tbtc (and those who are also radix'd) did you notice a difference on the top end? Good or bad? Did your trap speeds increase or decrease. With my tbtc (and LT's) my 60ft improved from a 2.1 to a 2.01, et's from a 14.39 to 14.15, but traps stayed even at 95mph. Now that Im blown, 1st and 2nd gear pull nice and falls flat in 3rd, convertor is unlocked as well? When I say fall flat, I mean once in third gear I could not pull away from a 5.3L 2wd truck running 14.1's, he wasnt gaining but still, wtf? Any ideas?

When I say fall flat, I mean once in third gear I could not pull away from a 5.3L 2wd truck running 14.1's, he wasnt gaining but still, wtf? Any ideas? are you running 22's at the track? With your mods you should be seeing better times with stock weight wheels. Also your 60ft should be in the high 1.8 or 1.9 range. I've cut 1.7's but that was with stock 17 steel wheels. With the centerline 22's I'm running 1.8's. I never thought about the TBTC hurting my 1/4 runs but it probably is. Once I get into 3rd the truck just seems slower and I think my trap speeds are a little slow. Quote Link to comment Share on other sites More sharing options...
