I wouldn't be making silly jokes about it if I was going to actually try and do such a silly thing
what I've done is this: looked over the Finn cars to try and see what people CAN do and CAN'T do in tuning. What I'm seeing is this:
-cost no object, go win and sell more Mercedes race cars
-tires are going to be either N3 for drifters and road cars, S3 for speed cars, or maybe sometimes R3 for the totally out of hand ones, but it seems like that's pushing it.
Get wings and fully configurable everything, the point is in how you set that stuff up, not how much performance you can get for X money (again, go and sell more Mercedes race cars until you don't care about money)
Lots of weight reduction, lots of turbos and stuff- cost is no object so it's more a matter of whether the car is simply overpowered, not how much the engine mods cost- also, whether it can respond to throttle or whether the turbo lag is too much. This is probably why I don't see a lot of Turbo 4. It makes me wonder what sort of cars might work with Turbo 4, considering that it would be very docile at low speeds because of turbo lag, but would kind of explode at speed
Don't worry, I am NOT going to copy and paste lots of Finn stuff. I'm just fooling around and steadily figuring out what I need to learn. I still think I'm a better tuner than a driver (not saying much!) but now I get to drive properly and my cars will, for the first time, translate to other DFP users, cockpit users etc. I think this is pretty awesome and don't need to fancy it up by imitating Finn 'promotional materials'.
Once I've dealt with a pile of business and tax paperwork and caught up on a bit of CD-mastering and plugin coding 'day job' work, I'll get back into the tuning and try to come up with some interesting cars worth trying out. I know one thing, this time I'm sticking to stuff people can just go out and buy and set up.
I'm tempted to try stuff that's real-world feasible: I have an old Buick Century with basically 'racing exhaust' IRL. Not because it's actually racing exhaust- it's just a glasspack muffler and stock cat- but because I have the air intake extended forward to the front engine compartment wall, the opposite hole sealed up with steel plates, so the grille air is forced through the radiator and/or into the air intake. Plus there's a K&R air filter replacing the stock one. It's the positioning of the air intake (almost like a scoop, another thing I'd like to try) that makes the engine get more power as highway speeds are reached. So some of the tunings I've done have been focussed on 'what could you actually do with the car if you had wrenches and stuff and a small amount of money for mufflers and air filters etc'.
But then, this is Gran Turismo 4. Why not be rich?
Anyway, it's an interesting part of the sim
