It got caught in the spam filter.

Also there will be no limiting of tire quality points or any other category for that matter. Putting points into one category at the expense of others can have serious reliability implications.

So I've got a car that's doing 4'11" flat around LeMans, but it seems like that's not going to be anywhere near enough to be competitive. I need to go find some engine tutorials or something I guess.

MrChips, I have just sent you a rules legal car and am currently working on a second entry. Also, can I request to be car number 33? I had #33 in every sport I played as a kid.


In other news, the engineers here at Phoenix Motorsports have been spending plenty of time in the lab looking for ways to make the car more competitive. Many of them are begging me to ditch forced induction so we may make more power through displacement. But I will not hear of such nonsense! Our "cuddlebug" 2.2L V8 stands at the heart of what makes Phoenix Motorsport great! We have found a replacement for displacement. They have however found other avenues from which they can squeeze performance.

Our latest discovery was that we could save a full 1.2lbs by simply switching our livery to a different colour.






Clearly, it is having a positive effect:

Yes. In fact, if you guys want to choose your numbers, pick two consecutive numbers (that aren't 1 or 2 - nobody gets to wear them this season - or 9 and 10, those are mine :v:) and let me know.

Test Day 1 is now complete:



Test Day 2 has been scheduled for Wednesday, June 24th for new entrants missing the deadline for the first test day. The timeline going forward looks like this:

24 June: Test Day 2, Circuit de Catalunya (new entrants only)
29 June: Final deadline for entries. No new entrants will be permitted after this day.
01 July: Final Test Day, all entrants
03 July: Entrant "Freeze Day"; all entrants designs will be considered "frozen" as of this day at 5pm Pacific Time. Only one engine revision will be allowed for the rest of the season after this point.
06 July: SA-GTE season begins!

I want to make my engine more economical, but every drop in hp I see gives me a physical pain in my chest and I just can't bring myself to do it.

Out here, everything hurts.




I think I may be doing as well as is possible with a 2800lb chassis, but those times really aren't competitive. Making this old thing faster really needs serious aero adjustments, or I have completely failed at gearing and tires. One of the two.

Anyone have any advice? If I got all the way to full downforce, I can get positive downforce numbers at full speed, but it significantly impacts my max speed. I think right now, my issue is that my rear end is floating at the upper end and robbing all my grip.

Lose weight, put on a rear wing and front lips, put 15 QP into tyres. Then start fiddling with the aero sliders. I suggest finding a neutral, non-lift setting first and then seeing where you can go from there.

The body is still not very aerodynamic however and you are fighting an uphill battle with an uneconomical engine.

Your car's what, 400lbs over minimum weight?
Lose it. You probably didn't make your engine with cast iron and avoid titanium rods, so why not modernise the chassis?

- Lose all the weight you can. Try to be underweight as much as possible and then make up weight with your "ballast"
- Put a rear and chin spoiler on your car. Even at stock values your rear should be providing downforce. The idea is to go as little downforce as possible without compromising top speed. This is where you are going to lose the bulk of your setup time. put a couple points into either front or rear downforce, see if that drastically affects your top speed, and tweak your gearing and suspension as necessary then run a lap. You'll eventually get to a place where a single point in either direction will cause a decrease in performance. If it's still too slow then you have to start getting drastic with your suspension setup.

But first lose all of that flab and watch those mph's soar.


[edit]Looking at the practice 1 chart, going by best lap I'm 4th. But I made so many stops I finished in 11th. gently caress.

OK, a quick elaboration on safety, as requested;

The rules state that all cars must have a minimum of Basic 00s, +4 Quality Points in the Safety category of their design. This can be thought of as a minimum level of safety equipment. The other minimum in the rules is that all cars must achieve a safety rating equal to or greater than 50.0. Now, if your car has a rating higher than 50.0 without meeting the Basic +4 safety criteria, it still must have Basic +4, even if your car has a 100.0 safety rating. If your car cannot achieve the 50.0 rating with Basic +4 (and there are a few body styles in the game that will not), or if you feel the need to go over and above the minimums, you can have higher-tech safety systems and more Quality Points in the Safety category without regard to the Quality Points allotted to the body/chassis/engine totals.

Basically adjust, test, repeat. It is amazing just how much more speed you can find with just a tweak here and a tweak there. Of course some more drastic measures might be needed but that's fine; my piece of advice would be to look to the history of muscle cars, specifically that of their racing derivatives, for inspiration. I for one look forward to the appearance of a Griffin GT Superbird. Just know that Smokey Yunick style cheating won't make it past scrutineering. :)

Nothing is determined from the beginning, and everything you mention is modelled in the simulation, sometimes quite cruelly I might add.

The LMP isn't really any faster than the modern sport car bodies, a separate class would be pretty useless. It has a pretty middling drag coefficient and the advantage on tire widths is irelevant here. The only advantage is the center of gravity seems to be a tiny bit lower but it's not terribly significant.

After much thought I am abandoning my previous FF gimmick pickup, the Decimator LX, for a FF economy sports coupe gimmick.

Presenting the Decimator Green Motion Spec-R E-Type


This beauty builds on all the things the Decimator team learned from the LX. While the LX was an entry level sports car built for the economy focused enthusiast who wanted to drive to the track and bring an extra set of tires, the Green Motion Spec-R E-Type is a true sports car for the green minded individual. Want to hang with supercars, but hate paying for the fuel? With our new White Top V8 while other drivers are in the pit getting fuel, you'll be on the track making laps.


In the Decimator Green Motion Spec-R E-Type sports and economy combine into one imposing package.

I know your LMP is faster but i'm pretty sure it has more to do with the engine than the chassis.

(And yes that is rules legal with full cooling and decent reliability)

It isn't too complicated; all of the entries except for one passed scrutineering on safety after all.

Referring back to the rules, all of the races are timed, with an assortment of 6-, 12- and 24-hour races.

I have no idea how the LMP would have done, frankly. Probably a bit better than the Wagonator, but not as much as you'd expect. On that note, there will be no other classes of car running in this; the amount of work involved with just the one class has ballooned beyond what I had expected it would, to the point that I'm thinking of capping entries as it is.

Look Riso, I've indulged you as far as I'm willing to now. Nobody else in here has made even so much as a word of complaint as to the rules; they've just knuckled under and come up with their own solution, many of which are far more creative than anything I could have possibly expected. Your choices are thus:

1) Shut up and comply with the rules, or

2) gently caress off.

Is it safe to assume that a cars fuel consumption will be somewhat consistent regardless of the types of tracks employed (ie using less fuel on fast tracks that emphasize power vs slower tracks that emphasize handling)?

Because if that is the case, then MrChips I may ask you for a screenshot of my engine file running on your machine. Unless something is loving up the calculations on your end, then I may have to emergency clean sheet the engine because I can't for the life of me figure these numbers out.

It will not be consistent from track to track. Higher speed tracks like Le Mans, Monza and Montreal have higher precentages of full throttle usage while the Nurburgring, Silverstone and COTA are quite a bit lower.

Some additional tips for fuel economy; making less horsepower will make you burn less fuel, and longer, wider spaced gearing will improve fuel economy. Both of these are at the expense of speed, so you need to balance the one or two seconds a lap you'll lose by the 50-80 second penalty (varies by track) incurred by a fuel stop.
