Hi everyone. I am reasonably new to tuning, only a few months now. But i am having an issue with gear ratios. Is there a formula or anything to help with setting gear ratios?.
I am wanting to tune a drag car, and i just don’t have a clue on setting the gears and the ratios good. I have tried and tried, and just can’t seem to get it right. But i am using a RWD car class S1 all upgraded to Race.
Also getting to much wheel spin, that is probably because i am using a RWD maybe?
I have lowered the final gear to speed, and set first gear lower to compensate, but loose a lot of time.
Set it higher. To much acceleration and not enough speed, takes longer to get up. I lose alot of my cars MPH/KMH. I could go and download a tune, but i would rather have satisfaction in knowing that i actually fully set up a drag car/tune of my own. Not someone elses.
I could have the same car as someone else.
Example: Porsche 911. They always get way out ahead and no chance of catching up to them. I have done tune after tune on all the parts. But it is the gear ratios i don’t have one clue about.
Any help would be greatly thanked appreciated 
Dear AussieStorm86,
I do not have a formula to gearboxes but I guess your problem is still using the RWD tunes… In this game, FH3, all my tunes are AWD (all wheel drive)… Additionally, in order to improve the performance, you should focus your attention to improve the acceleration and launch indexes of your cars…
In summary, I try to follow these guidelines: 1st – set a handling index you are comfortable with… for example: 6,7 for A cars or 7,6 for S1 cars; 2nd – buy the parts for your cars that reduce the weight and increase acceleration and launch indexes.
After install the parts, go for tuning… set the gear box to reduce 2000 or 2500 rpm variation among the gears.
I hope this information is usefull to you.
Enjoy and have fun.

In FH3 when it comes to drag racing I think there’s not a single situation where you could pick RWD and stay competitive… That’s because AWD conversion does not cost as much PI as it should. In higher classes I see cars jumping from high 8s in launch stats to 10 with an AWD conversion, that should’ve been far more costly in terms of PI given how much of an improvement it is, and this improvement is also verifiable in the game world as you can fine tune AWD to your liking.
Since AWD costs additional PI, you can add less power, but in drag racing all you need to do is keep your car straight, so you can go all out in power and sacrifice handling, and the speed penalty is irrelevant. I also imagine people race with manual and clutch and less gears depending on the car, which means they don’t upgrade the transmission, which saves valuable PI points in some cars.
