when setting the gear ratios for a car that will be doing 400 meter drag races, is there a definite formula for getting best time? should, for instance, the car hit max speed right at 400? or 300? or is it different for every car?

i know this is a little random and obscure, but i figure with a collection of people this large, there might be someone here who knows.

It's too long since I was involved to answer that question, but I would bet that macnutt will give you the answer to that one!

Cheers

I will explain how I know about this later somewhere...

You need to be a little more specific as per your request. Simply put there is a formula for attaining max attainable speed for a given distance.

However that is just thereoretical. In theory you would reach your dialed in rating, but because there are so many factors that come into play, weight distribution, suspension, tires, frame and body raking, altitude at which you are racing.

Could you give some specs on the car you're running? That would help a lot.

okay, so there isn't a universal formula.

i can't give specs on my car by cause my car is actually my 75 cars, and i don't feel like listing all that information 75 times over, nor do you feel like helping me do the math 75 times over i would presume.

but before you ask what my secret is in amassing the wealth necessary to own 75 race cars, i should point out that i am not a rich man, but a talented gran turismo 2 player.

thanks for the info, gretchen. i'd love to hear the story behind you becoming a drag racing expert.

Without going into it here as I said I would tell the story later, my uncle raced for years and I spent a lot of time with him, and then when I went to school for Mechanical Engineering I...Later...

GT3? That's pretty funny...formulas...

Well that's right out the window because while the physics of racing sims is pretty good, they can be a little off when it comes to 'stark' acceleration.

I've tried dropping the rear end, softening up the rearend as it's called, to get that weight transfer but the game doesn't understand it, so you just get an ass heavy car... How's that?

thought there might be a way to shave that last tenth off my times. guess not. oh well.

i'm really much more into the endurance racing anyway.

maybe gt4 will have the physics engine you're looking for, gretchen.

Actually 'drag' racing in GT isn't that great. I don't think so.

I much prefer the endurance as well, and really that is the game. I can't wait to get into GT4. Read an interview with that guy, you know who I mean, the head concept guy for the game. Anyhow it sounds like they've really done some nice things to it. Damage is my thing, if the damage and 'failure' physics suck the game kinda blows.

I find that if I'm going at it and I'm say tearing into a corner and it a short straight I'll hold the limiter off and over rev the engine, I have noticed that running out the tach with the limiter button help will carry your acceleration a bit. I tend to use a really close ratio on most tracks preferring to really pull out of the corners while the guys with low ends are chugging.

I really wish you could adjust and tinker with the turbo units. Of course there are no 'superchargers' in the there. Because then you could fire on an old GMC 6/71 and overdrive it, crushes the harmonic balancers, but man talk about 'outta the hole!!'

i couldn't agree more aboot damage. i hate it when i brake properly, following the racing line, and my friend just gases all the way into the turn, slams into the far wall, and beats me out of the corner.

as for tinkering with all the parts, that's not for me. just like in real life, i am strictly a driver. i'll let the real mechanics tune the car. if i could pay a few gt "credits" every race to have some ai controlled engineer tune my car for me, i would.
