I believe that many cars turn off the air conditioner at wide open throttle (at least corvette).
you could change the tune to leave the air on, but redirect it to help cool the air. It may work, but the money and time spent would probably cost more than meth injection. Also you would lose...
My friends own a high performace Corvette shop and specialize in FI and NA.
I help them out with sales and support and really know the NA side since I road race, but my knowledge of FI is still limited.
the knowledge I do have says that water methanol injection is the way to go with a higher...
The 3.42 gears that Chevy uses has always been a debate. MY Trailblazer SS has 4.10 gears from GM and my road race vette has 3.73s from GM so it is not like they do not have choices.
I think everyone has to remember the vette is designed for highspeed Autobahn type driving (more like road...
BTW - thanks to everyone that responded. On other boards people attack you here I got answers without attacks and that makes it much easier to understand.
yes it doesnt measure hp I just talked to our tuner about this (this is why I am inside the car and not under the hood). The calculation of hp is rate of climb of rpm versus mph increase or something like that.
Based on talking to him I think I understand.
Fundamentally speaking a car that...
the 10 rwhp would be 3.42 to 4.10s. if you changed from 3.42 to 3.73 it would be less loss.
Maybe it is just the result of the way the dyno works and calculates both.
4.10s are installed aftermarket not OEM. Options for a 6 speed mn6 are only 3.42s (a4 have 2.73 or upgrade performance to 3.15).
Isnt horespower a function of torque
hp = tq * rpm / 5250
if so then if tq is lower than so must hp.
corvette speed is registered from the wheel speed sensor so changing the gears has no affect on the speedo. chaning the tire size would have an effect.
An Automatic though would require a change in shift points to prevent over-revving.
The dyno is an above ground chassis dyno and works as...
Sorry RWHP - stands for Rear Wheel Horsepower
We dyno tons of corvettes and all of them result in about 10 rear wheel horsepower loss when comparing 3.42 gears to 4.10 gears.
I am not sure if I should post this in the gears section or the engine/fuel section, but I will start here.
the question is around gears and gas mileage. The discussion came up during a conversation about corvettes (which I happen to road race).
Corvettes from the factory come with 3.42 gears...
