If you do the math - ~3450lbs at 155mph in 1320' = 1050hp at the wheels. The last Heffner kit made 1005hp, so I'm sure one of Heff's 1000hp kits will do ~155 in the 1/4 as well.

Don't have to do the math, just look at the dynos:

Underground Racing 1026whp

Heffner's Performance 855whp

Almost 200whp difference! Question is why? Is UR simply boosting a lot more?

Not entirely true. Heffner also has a 1000+hp version. And I'm not taking sides, the UR run was incredible, but Heffner was the pioneer in the TT G.

Who will be crowned the title 'First Gallardo in the 9's'?????? UR or Heff???
