Ok, I had always wanted to know which part, not including power adders, was the best bang for the buck for acceleration. So, I ran an experiment.

Experiment details:
Car: Mazda RX-7 RS model w/ oil change
Control Value: 0-400m test, using automatic tranny to assure equal shifts
Experimental Value: Single, various parts installed.

I ran a maximum of three runs per part. If I noticed the first two runs were the same I omitted the thirdrun. If I noticed a large difference in the first and second run, a third run was taken.

The results are as follows...

Stock
14.237, 14.236

Suspension (left stock settings)
Sports - 14.203, 14.216, 14.216
Semi-Racing - 14.199, 14.199
Racing - 14.179, 14.180

Clutch
Single - 14.130, 14.130
Double - 14.057, 14.056
Triple - 14.037, 14.037

Flywheel
Sports - 14.076, 14.068, 14.067
Semi-Racing - 14.062, 14.062
Racing - 13.971, 13.971

Carbon Driveshaft
14.029, 14.015, 14.015

LSD (all types showed the same results)
14.200, 14.200

Tires
T1 - 14.097, 14.097
T2 - 14.069, 14.097, 14.097
T3 - 14.019, 14.031, 14.024
T4 - 13.979, 13.983, 13.979
T5 - 13.933, 13.933
T6 - 13.920, 13.892, 13.892
T7 - 13.781, 13.781
T8 - 13.715, 13.715


I really don't know what to do with this information... I was thinking of taking the individual prices of each item and then determining a time/dollar ratio of the parts. From what I see, the racing flywheel is the best thing you can do (aside from a power mod, to increase the acceleration of your vehicle. While the tires are great for decreasing your time, their high cost really doesn't make them a cheap form of power increase for straight line performance.

Also, this obviously only applies to one vehicle and one type of drivetrain, but maybe I can test this out for a 4WD, FF, MR and RR setup to see if it does the same, or is different.
 
Neat stuff, I've never thought about this really.
 
Nice to have numbers to go with it, but I've always found the race flywheel and 3-plate clutch to be the cheapest way to boost acceleration without adding HP.

Excellent work!
 
Stock means standard, where it says stock in bold that is the car left unmodded, where it says stock settings that means the settings havn't been changed.
 
which rpm did you launch at cause thats a variable we can control and changes results. (unlike reaction time aince we cant trol that..)
 
Ryen is totally correct if you launch from a rpm then ur time are not 100% accurate, you can just dont rev until it says go then launch even though u have a slower time ull have a more accurate time IMO. But you did a wonderful job must have took a while but yeah good times.
 
I just gave a full RPM launch each time. I did this so I would have a consistant. I know that you can get a faster time by launching at a specific RPM but I would of had to do a lot more runs to get consistant results.

ditto

nice work! :)
 
That is impressive. If I didnt have much money to tune a car with, I would just make sure I could the the clutch, best flywheel, and chip to get it better.
 
interesting experiment and i can see you have invested alot of time in it. hey i dont want to sound like a narc, but buying adjustable parts and not tuning them disguises its potential result. that is the only flaw in this excercise i can see. besides from that i think that this experiment is very beneficial in the (cashwish critical) early stages of the game. i know one day i will be using these results. :)
 
Each adjustable part ALSO gives a benefit if you don't utilise the adjustment feature - the suspension parts will gradually lower your car (amongst other things) and the transmission parts will gradually shorten your gear ratios.
 
yes true. but paying out cr14,000 fir suspension parts or racing gears and not tuning them to the best of thier abilities does not justify its outrageous cost.
 
And then lends a variable to the test.

For test purposes, buying the part is enough, as it lends a tangible, constant change in the car.

Yep, same here. I also do the first stage weight reduction. That really helps too.

Why didn't you do a comparison of weight reduction?
