For those of us following the plenum wars:
By now we have all seen the dyno results from mustang depot that state 70-75mm throttle bodies basically outflow the stock 65mm T-Body and produce a higher torque curve and hp ratings. Today I finally ripped off the 65mm and put on a 70mm T-body. I did this swap once before and lost a noticeable amount of low end torque, so I sold the 70. I had my fingers crossed that this plenum could better utilize a 70mm, so I bought yet another one. Unfortunately I don't have any dyno's or tracks nearby, so I did the next best thing. I slammed the gas from a roll, from a stop, and on the highway.
To make this analysis short, lets just say the 65mm wins hands down in the low end torque department. The 70mm feels much better than it did with the stock plenum, but the 65mm is still champion. I encourage all of you who have blown $$$ on these plenums to try the same experiment. Though I have not experienced the C&L, Dragon, or Trick Flow plenum, I am confident you will all notice a much better pull with the stock T-body in place. The 70mm feels good up top, but it takes longer to get up to speed.
To each his own..
