how gear ratios affect dyno results

[PRowlett]

I was checking on the air intakes, and to my surprise I found one that says that it can get up to 24 hp. TQ Gain: up to 29 lbs./ft. on a stock engine: https://www.carid.com/2004-chevy-cor...287635845.html Of course there is no DYNO diagram to prove it, unless not on the website. Do you think it's even possible?

anything is possible. would you get that on a completely stock unmodified car? most likely not. maybe their test car had headers and a catback system already on it. that would increase the numbers for the air intake.

Heck, anything is possible, I guess. Each engine is different, and some respond to even minor mods better than others. Some aftermarket intakes might flow more air, but not filter the air as well as others, whereas others will try harder to keep contaminants out of the incoming air and therefore be more restrictive on the actual airflow. There are always tradeoffs in designs.

Just try to make decisions that are rational for a street driven car if you are driving it on the street.

Yeah, the Edge programmer I have on my diesel truck says that it will gain 100 hp and 200 ft/lbs of torque without any further mods on the highest setting. I have a 4 inch exhaust system on it so it should be doing better than it claims. I only run it on the 80 hp, 100 ft/lbs setting and it's pretty impressive.
