Your first statement totally contradicts itself by the way. I'm not trying to get in a pissing contest here either. If you want to buy a $50 emi filter than do so. If someone wants to buy the Sun Perfomance hyper voltage system for a $105 or the one that has APEXi name brand for $200 or any other brand for that matter, let them. What I'm trying to do here is explain why and how the device works to let people make an informed decision. There are always variables that can be changed in any situation on a dyno. If your dyno fluctuates 20whp or so between pulls than I'm afraid your dyno or person running the dyno sucks. I have many pulls on a couple different types, and all my runs are consistant within 1-3whp if no changes were made.

Needless to say, I'd rather provide useful information to others on this site rather than just provide a shitty statement without justification similar to all the other thread trends I've been seeing lately. Let them make their own EDUCATED decision as what they want to spend their hard earned money on.

 

blah blah blah.. i've seen it all. make a pull with the hood closed pull 305whp, open the hood run again and viola 324whp. pull the car on the dyno after it's been sitting and the air in the tires is cold, pull 310whp, on the seocnd pull the air is hot, the pressure is higher and you pull 5whp more. do a pull with the garage doors closed and only the exhaust evacuation tube hooked up, pull 315whp, open up the doors get fresh air in and viola 10 extra whp.

chasis dynos should never be used to gauge how much power an item gives you, because it's totally inacurate for that. chasis dynos are tuning tools, nothing more, nothing less. the only way to see how mucch power an item gives you is in a completely controlled enviroment engine dyno.

why do you think all of these companies claim "up to xx.xx more horspower" instead of just blatently stating "gives you xx.xx horspower"? cause they can't prove what they say, they have to advertise in a way that will give them a foot to stand on if someone comes after them

 

I think this and the hyper voltage system is only good for people who are running a lot of electrical components.. suchs as a sound system, gaem system, etc.. I could be wrong but Im pretty sure thats what it is made for so you can get a better ground and voltage throughout the car without losing it.. like a capacitor kinda but prolly a little better
