I'm not saying it doesn't work, I'm just saying that this has been around for a while now and is not worth the money, IMO. If you AutoX or something like that where you go WOT almost constantly for long periods of time, then yes this would be a good investment. But for a 1/4 mile of track? I highly doubt this will help much, if any at all.

Would I waste my money on this? Nope. There MAY be minimal gains to be found with something like this, but I'd rather spend that money elsewhere (like on a water injection kit that WILL actually do what this claims to do, but do it MUCH better).
