This is my first post, but I've gotten so much information from this helpful site that it seems time to pay back a bit. I haven't actually found this particular grind recommended anywhere else. I'll give full details of my setup below.
ONLINE B-spec Challenge No. 5, 500PP Autumn Ring / 5 Laps
Car: Lotus Elise 111R '04
6,717,000 cr./hr. (895,600 every 7:30 to 7:45, plus 20 seconds or so to press X-X-O-X-X-X). That's cr. 111,950/min.
including the time between races.
Hitting the 20 Million limit, then, takes only about 3 hours start to finish
assuming you're at zero, and if you time it right, you're only pushing buttons for about 10 minutes out of the 3 hours. (I grind while watching TV, and check GT5 at the commercials.)
It seems an anomaly to me that this race, recommending only a Level 20 driver, pays out better than the 650PP event (below), but there you go. At these prize levels, the 200% login bonus obviously pays off handsomely. The experience is excellent, too, but I can't say it's the highest per minute. I do think this is the highest cr./min. in the game, based on all the other recommendations I've seen, at least for B-Spec:
First Place:
447,200 x 200%=895,600 cr.
86,200 x 200%=172,400 exp.
Typical finishes: 7:30–7:45
Côte d'Azur, the 650PP race in this same Event (and recommending Class 30 drivers) pays out less, at only 441,900 cr. (883,800 with 200% bonus),
and it takes longer to complete IIRC. It was very much harder for me to win than the 500PP when I did the series for the gold. Indeed, I doubt it's possible to win Côte d'Azur unattended, save perhaps with the Chapparral 2J, which I don't have. And even with the 2J, those 2 corners that nail everyone are killers! (Unsure what the experience point payout is there, and don't want the pain of re-running it to find out! :-) )
The Lotus Elise 111R '04 is conveniently available at the offline Lotus dealership, coming in stock at PP447/189HP/860kg, for only cr. 54,400. (Bonus, being a Premium car, you can get a nice cockpit view on those rare occasions you decide to watch Bob do his thing, or even help him along.)
I had to de-tune an existing one when I started, for example removing turbos and downgrading intake parts, but instead let me show you just how I would build up this car from new at the dealer for minimum investment to the 500PP grind-mobile.
1. From GT Auto:
a. cr. 250, change oil (yes, even if new), 443->450PP.
b. For the grinder, you won't need the RM (Racing Modifications) or any Aero Kits. I'm tempted to experiment with them, but I fear I'd have to back down the power side far too much, to get back down to 500PP; my RM version of the Elise with full Aero comes in at 574PP.
2. From Tuning Shop, purchase the following:
a. cr. 15,000, Suspension: Fully Customizable Kit
b. cr. 2,500, Drivetrain: Twin Plate Clutch
c. cr. 1,500, Drivetrain: Semi Racing Flywheel
d. cr. 7,500, Drivetrain: Adjustable LSD
e. cr. 20,000, Transmission: Fully Customizable
f. cr. 10,000, Exhaust: Titanium Racing 188->203HP; 443->453PP
g. cr. 500, Exhaust: Catalytic Converter Sports 203->209HP; 453->457HP
h. cr. 1,000 Engine: ECU Tuning 209->220HP; 457->464PP
i. cr. 2,500 Engine: Stage 1 Tuning 220->222HP; 464->466PP
j. cr. 15,000 Engine: Stage 2 Tuning 222->225HP; 466->467PP
k. cr. 30,000 Engine: Stage 3 Tuning 225->227HP; 467->468PP
l. cr. 5,000 Body: Stage 1 Wt. Red. 860->808kg; 468->481PP
m. cr. 10,000 Body: Stage 2 Wt. Red. 808->791kg; 481->486PP
n. cr. 20,000 Body: Stage 3 Wt. Red. 791->774kg;486->491PP
o. cr. 20,000 Body: Chassis Reinforcement
p. cr. 3,000 Body: Window Weight Reduction 774->764kg; 491->493PP
q. cr. 5,000 Body: Carbon Hood 764->759kg; 493->495PP
You don't need Racing tires, as the event limits you to the stock Sports Hard.
Hmm, 495PP. The remainder must come from the PP you gain breaking in the engine by racing; I actually have to turn my power limiter down to 99.4% on my grinder.
Now to setup (no credit to me--found this online, probably on this site.)
Ballast: 0
Engine: (None at this time, but from here on out use the bare minimum power limiter reduction to keep at or below 500PP; that and oil changes every 10 or so races should be all you ever need to do for this grind.)
Transmission: Set Top Speed to 124; let the gears sort themselves out. (You'll max out at about 120mph at the end of the S/F straight on Autumn Ring, so gearing beyond that is wasted.)
Drivetrain: LSD 20/40/7
Suspension:
RH: -25/-25
SR: 6.5/10.0
D(E): 7/8
D(C): 6/5
AR: 3/3
Alignment:
CA(-): 1.3/1.5
TA: 0.10/-0.15
Brakes: 6/5
That's cr. 168,750 in mods and oil, plus the original 54,400 for the Elise, for a total investment of cr. 223,150. To verify all of the above, I followed these instructions on a new Elise, popped it into the event (with a Level 35 relatively cool Bob), pressed start, and didn't touch the controller. 7:49.172 seconds later, I was cr. 895,600 richer (cr. 672,450 net), Bob having taken the lead by Lap 4, and finishing 13.790 up on second place. It's particularly gratifying to see this little gem blowing past another Elise 111R '04 when it appears.
I'm sure the tune could be tweaked, but having never lost
this race with
this car, I can't see investing the time. When I actually give Bob some coaching, I can get lap times down into the 1:27s, and finish overall in 7:30ish.
Hope the info is of use to some folks here. I've been on a buying spree just because I hate hitting the 20 Mill limit and not getting full prize money, even with credits being so easy to acquire here. Thought I should share the secret sauce.
Cheers, all.
Additional Notes:
2d race in this car: 7:47.162, 18.137 over 2d place, no coaching.
3d race: 7:36.777, 2d place didn't register a time before it flipped to my prize screen (decided to coach Bob a little; he had the lead by about 200 yards into lap 3.)
After the 3d race, a trip to the garage showed an oil change taking me from 229HP to 241HP (495->503PP), so I guess the break-in happens pretty quickly. Since the car was now overqualified for the Seasonal, I de-tuned it to 236HP/500PP by turning the Power Limiter to 98.0%. From here on out, lather, rinse and repeat. :-)
Note: for the next few races, I consistently got "Regulations Breached" messages at the beginning of each, easily resolved by choosing Settings on the enter race screen, and tuning the power limiter down a click or two. I'll be curious to see how long the break-in continues.
Finally, I forgot to mention the Seasonal's prize: including the three for these 3 races, I have now amassed 239 Racing Suits! Woo-hoo! Meh. :-)
