Default how gear ratios affect dyno results

this was on my 2000 pontiac formula automatic when i did gear testing for mikronite through vinci high performance. basically the easier it is to turn, the less energy is exerted and lower dyno numbers are a result. of course your acceleration is quicker, resulting in lower et.

this graph shows my stock 3.42 gear vs 4.10 gear.



this graph shows 4.10 gear vs 3.73 gear

I changed gears on my Jeep Cherokee XJ when installed 33 tires, and never actually thought about something like this for corvette, but your DYNO looks very impressive. I must say that speedy acceleration is much more entertaining for me than a high speed run, so I can easily sacrifice lower gains at high RPM.
I was thinking about getting an air intake first, I assume it will give me about +5-10HP.

you would be correct on the air intake.

Just remember that when you do a gear change, when driving a stick shift, redline will be reached a LOT quicker than before.

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.
