Snyder's R5 is very fast (except Sunset as he said) - I think we need to get Serial involved :D

Going back to Monday, I hadn't realised how close I came in the GTO to taking out fndr (Miura) during THAT SLIDE...



Merry Christmas everyone!!!

Had a bit of a Blitz early this morning.  All my times listed in one.

                        Sunset                 Sebring      total
MR2 GT             127.615             90.407       218.022
Porsche 996     127.647              90.085       217.732
BMW E46          128.654              90.080       218.734
Supra GT          128.700              90.552       219.252
Supra RZ          128.501              90.119        218.620
Ferrari F355     128.318              89.915        218.223
Mustang GT      128.386              89.553       217.939

Biggest suprise is the Mustang GT, I think it wins overall for me, as it should go well on the tighter tracks also.  Fastest overall was the Porsche.  Supra GT has a lot more potential, but couldn't get it hooked up properly.  If I get more time I might try and get the E46 times down a bit more as that was 1st run.  I also think the MR2 will go faster on Sunset if I change the aero setup, there was just a touch too much understeer meaning I had to lift off a lot.

Looks good Fndr... I'll have to give this a go when I get back from visiting family over Christmas.

These 2 tracks do seem to suit the GTO so i'm hoping for some good times... I'm regulary in the 127's at Sebring and can just get into the 89's at Sunset, when we ran the testing on Monday I found the same as Spiny in that low downforce didn't work quite as well as i'd hoped at Sunset so I went back to Sebring levels of DF and it was much better.

Like Open i'm also running on the Pirellis they do take a little while to start working, but when I ran an extended test at Sebring I managed 16 laps with ease and just over 50% wear... I could have gone longer but it started to cut out as I came onto the back straight as i'd run out of fuel...  :-\

Hm ....

16 * 3 = 48. 

We're doing 50 laps.

Just sayin....

Were I to run the Renault in an enduro, it would prolly run through tires incredible quickly.  Even with full downforce it gets jumpy going over bumps and curbs, so on bad tires it would probably be awful to drive.  I tried out a Pontiac Solstice, but the car is too heavy with not enough acceleration or top end, gunna try the Saturn Sky, next and then some RX-7's.

Renault Times to beat:

Road Atlanta: 81.8xx
Suzuka: 121.9xx
Sebring: 126.3xx

Renault 5 Turbo

Sebring - 125.408
Sunset Infield - 88.631


I took off a bunch of downforce for Sunset, and it made the Renault incredible fast, much faster than I expected.

AB Flag RX-7

Sebring - 127.909
Sunset Infield - 89.301


The Ab Flag seems capable of low 127's but i might need to change the downforce up a bit, plus tune the car more for Sebring.  At Sunset it seems capable of perhaps running an 88, but it will take practice.

Yeah, that was pretty close.  I was sure I was going into the wall; good job holding there.

Yeah its gonna be tight, but I think (hope) some short shifting may help to give me just enough fuel to reach the pits at the end of lap 16 without cutting out so...

17 * 3 = 51  ;)

I hope that short shifting will make you slow enough to pass  :P

Perhaps Heidi's lack of aero may give me an economy advantage?  8)
It is highly likely that the above post was produced with a drippy jowl.

Well, the girlfriend got me the Wheel for X-mas, and so far I'm about 3 seconds off my time at Sebring, and anywhere from a half-second to 5 seconds off the pace elsewhere.  I'm also not as consistent with the wheel, yet.

I really would like to be back up to snuff before the series starts, so I can run with the wheel.

I also haven't raced much online with the wheel yet, mainly because I don't want to be running everyone off the road when I go spinning out of corners. XD

Maybe I'll just use the controller. =D

When will the first race of the series be?  Still testing cars like crazy, but Forza is a fading moon to me, don't know how much longer I'll be playing it.  Hopefully this series will spark something and get me back into the groove.

I took the Ferrari GTO out for a run, I had to make some changes to the tune between running the two tracks, Sunset needed stiffer RB's and slight changes to the damping...

I think i'm going to have to go for the risky 2 stop stratagy to stand any chance of beating Snyder's Renault 5, has anyone else tested to see how far they can go one one tank?

Sebring - 127.259

Sunset - 89.486

Nope not yet, i'm pretty sure I'll burn through tires pretty fast running Avons.  Anyone up for testing today?

Yeah, that was pretty close.  I was sure I was going into the wall; good job holding there.

Got to admit that I knew I'd lost it, so I just floored the power so it would spin out inwards and hopefully avoid you (it worked! :)). If I'd backed off the power I would probably have ended up taking you out.

Going back to Pete's comment agreeing with me about the d/f on Sunset, here's another thing to thow into the mix. As you can see from the pic,my GTO has no wings, just the Forza rear bumper yet it is faster than my 80% d/f'ed Miura at Sebring. That is another thing which has me a little puzzled as I would have expected Sebring to be less biased to a low d/f set-up than Sunset.

Which brings me to my problem with the Miura. It really doesn't like kerbs, and I think that is why I'm struggling with the lower d/f set-up. I'm reluctant to mess with the springs as they seem to be pretty well set in terms of they only go red when I hit a major bump of kerb. Likewise, I'm reluctant to fiddle around with the ARBs as the car settles well once in a corner and you can very easily adjust the line on the throttle without it trying to spin out on you.

Which means I either have to use the higher d/f settings to control it over those bumps, or I have to confront my daemons and start playing with the damping. Generally I shy away from major adjustments, only changing the settings by 0.1 or 0.2 to assist under braking or acceleration. But here I suspect that the car is overdamped for hitting kerbs, especially at the back. I need to go and check the telemetry, but it feels as if the rear suspension is still trying to bounce as I come off the kerb and that is leading to the snap oversteer I'm seeing ( I know it doesn't help being a MR configuration, but so is the GTO and that doesn't have the same issues despite no rear wing). If the telemetry confirms my suspiscions, I'm going to try increasing the rear bump setting (and the corresponding rebound with it). This may lead to all sorts of other issues coming to light, but I figure it's worth a try. If the worst comes to the worst, I can always go back to my current set-up which is good for a mid 2:07 at Sebring and mid 1:29 at Sunset, but is really better suited to the twisty tracks.
