Not sure what his powerl loss ratio is from crank to wheel, but wouldn't think it would be more than 22-23%. Am I off? The ESS kits seem to yeild better numbers. Maybe this is why sooooo many folks have these kits.  |
Please remember the dyno he has posted is my first set of dyno numbers with no boost log.(My setup has changed with different exhaust parts) The day after that dyno i went to another with a boost log and it was only 6.5 psi. Dyno's aren't everything and AA kits aren't dyno queens. If you want real world results my 501 hp vs 590 hp ess at Atco AA wins all day. Also FBO 335 beating ess vt-2 kits on the street. So you can judge yourself fairly instead of bias info.
I am the sedan and the e92 with the flag in the back is M33 that run 120 ess 122 AA both of us had traction issue.
