Thanks for confirming all of thisPowolotti wrote:I was surprised (and suspicious) as you are. Transmission was 1) calcualted by the Dyno (Amerschläger P4) and after the low peak and high torque 2) checked by a Lammy gearbox table and the calculation was correct. All runs are in 3rd gear. Varitronic Ignition has to be set at the Dyno software (Value 0,5 - which means 2 pulses per revolution). The people owning the dyno also checked everything again.
I think it is important not to look at bhp on different dynos, but on the curve itself - how does the engine perform and when (at which revs). The Dyno i use has a 5% +/- tolerance, so in the worst case you might do a run with + 5% (eg 31,5 bhp) and on another run you will read -5%, 28,5. Tyre pressure and engine temperature also make differences. At the Dynoplace there was an exhaust from Pipe Design, "Duster" which is also a very long and fat pipe and produces about the same curves like the italian SM pipe on heavy tuned malossi cylinders.
I am getting a CE pipe within the next week and will test it against the italian pipe, maybe these two are totally different (?)
It will be very interesting to see how the CE pipe (that I have) compares with the others you have tested on this kit, and obviously it would be great if you would continue to post your findings up on this forum
