Default dyno testing affected by: must read this

okay,,i posted a dissapointing thread but must take it all back. I talked to a guy who talked to a guy. Told me something regarding my gear change to 3:73. So I did some looking and this is what I found.

Re: Does changing the rear gear ratio change the RWHP #and/or torque? (mowrey96)
Changing to a lower gear, 3.73, 4.10. or higher, increases the torque multiplication force applied to your rear wheels, but lessens the horsepower. Lower gears increase the rate at which power is applied, i.e., faster acceleration. Going to a higher gear reduces the rate of change , but increases the amount of power (power is a function of time) that can be put down, faster top speed, less change of rate (acceleration). It is just a simple engineering trade-off associated with auto dynamics.



so even though i got 268 rwhp I probably would have been higher had I had 2:73 or 3:31 gears. I did change my bama tune from street to performance after dyno. I am getting another next weekend and will post results. I must say, my car lights up the tires if I turn everything off though.

hope you all liked the info

faster top speed, less change of rate (acceleration)
poorly worded

lower gear ratio: higher top speed but slower acceleration

high gear ratio: accelerates faster but has a lower top speed

Having had 3.73 in my '10 , I feel the 3.31 that came with my 6'er is much better gear IMHO I do get good accel. and good top end.

you can't really compare 2010 to 2011 because the final gear ratios on the transmissions are different
