Well then.. After work I decided to fill up my Kizashi with 93 octane, and I was veeeerrryyyy impressed & shocked how much better it performed, I was shocked lol, I don't think I will ever go back to lower octane gas ever again, the throttle response is crazy

Quicker off the line with 93?

To be honest, I'm surprised that you saw that kind of difference. What brand of Gas was it?

Yeah it was quicker off the line def & it was Marathon, they had the old school pumps but I don't think that matters, I feel it much quicker off the line, plus I got this installed in the front of the intake tubing, it does increase the response with it too but not too much, every time I step on the gas pedal I feel more air coming into the engine, it sounds like I have an intake, plus it says I get 1 to 2 extra mpg http://www.ebay.com/itm/250842545418?ss ... 1439.l2649

I heard go-fast stickers add extra 20-30hp at the wheels too

lolz

Yeah I'll for sure cover my car in these http://www.ihatestickers.com/motorsport ... ower-p-255

I, too, notice an increase in performance (and mileage) when I (normally) fill up with Mobil 93......

I can promise you I am no sucker

I can't see how you could physically pump more air into the engine by using an impeller which is powered by the same amount of air coming into it. Besides with that impeller intruding, you'd actually be getting LESS air coming in as it'd be restricting the air flow. The only possible way to improve air flow and mix (without going FI) is to have small vertices along the intake tube to optimise the air flow and maintain air pressure, also you could go with a larger ram effect to increase air speed, volume and pressure.

Hate to break it to you, but you wasted your money on these ebay gimmics. It's the better fuel quality and increased octane that's giving you better engine performance at the moment.
