I am trying to see how many members in this forum have purchased the Granatelli wires from the forum sponsor StingThis which reports that with their wire set you will get an increase of 13hp?
Only if you add "Slick 50".Correct me if I'm wrong, but I seem to remember the video stating that an oil change was also performed prior to re-dynoing with their wires. Every time I've changed out old oil in any vehicle, there is a noticeable increase in power... my .02
Changing out old oil with fresh leads to measurable HP gains. The gains are even more pronounced if changing conventional oil out for synthetic.Only if you add "Slick 50".
Seriously, on an engine that already delivers 460 HP I really do not think you are going to "feel" anything different, seat of the pants, by adding another 8 - 13 HP. This would be true of any easy bolt on's ie. air filters, wires, etc. If you start hitting 30 or more HP or torque, due to headers, tune etc. you will start to feel that. If you want to feel a real difference in a car that already has 460 HP, you start talking forced induction and/or headers and tune. I certainly think someone can imagine feeling an additional 8 HP once they spend a couple of hundred dollars for something.I purchased these cables I was expecting a lot from them but to seriously tell you these cables didn't meet up to my expectations, I don't think it gives the performance which it promises to give.
Even if it happens, no one will ever think to make the link from the new wires, to the radio frequencies emitted from them, to disturbed vehicle electronics.More important question to me, after changing the wires, did anyone notice any change in the performance of the vehicle's electronics due to RFI effects?
