That does surprise me. I do not like Zoomies especially with a front engine car but I have several sets may try them some day. https://postimg.cc/gallery/np3zpruo/"Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge. Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion |

| That's a significant improvement. Is that in the 1/4 or the 1/8 ? quote: Originally posted by I Hate Dragsters:

| Wow I was thinking maybe no gain at all. I wanted something to not stir the dirt up like my downsweeps do at dirt and grass pits. Looks like Chris is going to fix me up. Much appreciated and I will try and do a back to back comparison if I don’t run out of tow fuel money. Funny but not funny. I appreciate the reply’s and Thanks for everyone’s time.

| Definitely a gain on boosted stuff, helps with torque off the line as well

carbs or injection. Carbs don't seem to pickup. My thought is because how carb works and dependence on air velocity thru it in relation to exhaust. Either back pressure or collectors scavenging effect.
