Also, the power figures given are for crankshaft values and not at the rear wheel. To figure rear wheel horsepower you need to derate the crankshaft readings by approximately 15%. That gives the RWHP ratings at 68 and 59.5, so don't be surprised when you get to the dyno.

I would be curious to take out the headers on a TBS and a TB to see if there is a difference there other than the crossover.
I had a long conversation with the chief of service at a local shop here. He is the one who finally convinced me to put the cams in because the price was quite right. According to him the biggest restriction to increase the HP will be at the headers. Just for the sake of it I will look at the headers on my Sprint to see if it would fit.
I would think that the air box filter is the same on both but I do not know if the TB has the extra air chamber connected to the air filter box. English is a second language and I am missing the word for that extra box. (caisse de raisonnance)
Before changing the cams, the dyno numbers are 77.7 HP at the wheel and 50.6 ft-lbs torque. Of course I could be happy with that but why not try for more. (all stock except the of road pipes)
I will order the jet kit since I am allready on the lean side with the mixture screws open at 2 1/2 turns out.
