Anyway, why all the hostility toward a guy with no track experience that was just enthusiastic about a great car and how good it runs with some mods he did? Some people act like it was a challenge to their manhood. If you want to straighten the guy out about how hard low 11's are to run then just say to him what the deal is without insulting the guy. The fact is that if you do run low 11's, you probably don't have any real handling worth talking about with 20 lbs of air in your rear street et's and no front sway bar on you bouncing 90/10 shock set-up. Get real and back off already.
Didnt realize that I was being hostile there boss More constructive information. I am just speaking based on info I have gotten from some of the more competitive 1/4 mile racers around. By the way I have been high tens (just dont have the timeslip so dont post something I cant prove with paper). What gear are you running and what have you ran? Again not trying to insult just trying to help. Guess you cant tell tone and gesture from written word (big surprise). Take care bro

Most guys think of engine mods effecting RWHP only....Stop right there!
Just like a torque converter....the 4.10's multiply the HP coming from the transmission tailshaft and put even more to the ground...
Most people don't realize this. Our shop does a trmendous amount of rear ratio changes and the results are always amazing.....
Also, from a tuning standpoint, you can be much more aggressive with tuning because with a higher ratio there is less load on the engine...
Things not to overlook when comparing his engine mods to others...Don's got something big...and it ain't under the hood!

Larger gears use horsepower and you only accelerate faster. (quicker of out of the hole slower top end) You would normally use larger gears in a car that needs help out of the hole.
I have a bone stock auto with 3.15s and I have smoked the stock tires out of the hole. Just imagine what Dyno Dons car will do with 4.10s and his mods Unfortunately, a good bit of his horsepower may go up in tire smoke with the stock tires.
Since when does going to 4.10's multiply HP? Dyno back to back and you'll see you'll lose HP on the dyno. The only thing that may increase is torque. New math I guess.
Differential gear ratio neither adds, subtracts, multiplies, or divides horsepower or torque. Only the engine is capable of producing horsepower and torque. Higher numerical gearing allows quicker acceleration as it turns the drive wheels at higher rate/ratio then a lower numerical gear.

The wheels spin slower with 4.10's than with 3.42's. Just like 1nd gear spins slower than 2nd. 4.10's are like having a gear under 1st.
For those that think they hurt you.....put in 4.10's and start in second.
You pick the gears by your trap speed in 4th. If you are looking for 130 get 4.10's. If you're looking for 138 get 3.90's. We are assuming you have a cam with a power band matching the max usable rpm for that trap speed.
1st you gear it then you increase power until you can't get it to the ground.

Maybe I said it incorrectly but if you change from a 2.73 to a 4.10 rear you will use a small amount of horsepower. (drive train loss we usually use a percentage well it would be minimally larger do to the larger gears) Actually shopdog could probably explain this much better!
