Sixes and Eights (and Four) - Closed

[TopBoost]

The Deep South...

Top climbs in behind the wheel of a dusty '73 porsche.  He stares at the Grant steering wheel, gritting his teeth.  Placing his hands in the 10 & 2 positions, he squeezes the wheel, trying to release every bit of frustration that's mounting with the heat of the afternoon...

"Hey, Mac," Top yells.  "I mean, what gives?  There's got to be more grip in this thing."

The elder mechanic looks up in repose from his lawn chair.  He runs his hands through his gray hair in frustration, then shakes his head.
"You got me, Top." he says.  "Why are you fooling with this old Porsche in the first place?"

Top releases the Grant wheel and swings out of the Porsche.  He casts his eyes at the hazy white September sky.  "At this point... I honestly don't know, Mac."

McQueen, itching to let loose an I-Told-You-So, grins at Top.

"We had a perfectly good Z/28 trailered up..." He says.

Top drops his eyes, studying the hot top, and mutters, "Don't remind me."



Working with the '73 Porsche, I slid to a 132.525.  There's some more grip in that thing, but I've yet to find it.  Suggestions, Bimmer?   Fndr? Fit? Bueller?

were you here for the FCT challenge with the 911?  There's some good advice in there.  Maintenance throttle is your friend.  The fact that we're on DOT's, however....

[Hoplee]

A little over a year ago, we took the muscle out to Suzuka West. Serial was the fastest thing on wheels driving the Stingray, and 4 ZR-1s rounded out the top five on the LB. However, we can't use the 'vettes this time, so I looked up the fastest time that wasn't a vette and it was ...

*drum roll please

!SURPRISE!
Serial in a GT500KR! 

Waaay on down the list, the fastest Z28 was driven by Ske, behind more than a few SS Camaros.

Here's the link to the original challenge thread for everyone's reference:

And for good measure, here's a link to the FCT challenge that featured the 73 carrera RS:

I'll let you know around Friday what it can do, it turns out the ladies prefer Saturday this week, so Friday just turned into Raceday!

RP97 was faster in the 'Cuda....

[Serial]

Got some time to put in a few laps in 2 different cars.  The first was the same B700 DOT Z28 I've been running for....well...a long time.

Camaro Z28
2:10.405 (130.405)

The second car was the 911.  I had one in B with Slicks - I downgraded those for some BFG DOTs, then set the tune back to default.  Turned down the tire pressure to 28/27, lowered the diff to 20/15 and ran some laps.

Carrera RS
2:11.198 (131.198)

The Z28 just needs to be driven harder to be faster, the tune is pretty solid at this point.  The RS needs a little tuning to get that rear end under control, then it might have a chance at putting up similar numbers to the Z...but probably not quite as fast.

[Hoplee]

Serial, I'm enjoying the Z, but I can't remember where your build is posted so that I can compare. So far, my build is responding best to the maximum tire width, which gives the tires a slight stagger, front to rear, which I've (once again) found to be of benefit to transitional handling. I can't make up my mind about the wing, but decided to try it in order to improve braking if nothing else.

I'm honestly surprised that your 73RS is falling behind the American Iron, at this point, and in my hands, it's the faster of the two. Its current advantage over my Z28, given the all-grip 1810 lb build, is mostly due to vastly superior braking performance.

[BarbecuePete]

Bit late in on this one but Im gonna try building up a Batmobile as well, always had a bit of a soft spot for those... also gonna give the Shelby a go as the one I've got is not doing much in its current set up for ALS 400...

Not even gonna bother with the Porsche for now... Im still too traumatised from Hop's Mugello challange to go back near it yet... lol

[chuckrateez]

were you here for the FCT challenge with the 911?  There's some good advice in there.  Maintenance throttle is your friend.  The fact that we're on DOT's, however....

   Truer words were never spoken.  I had a 911 built up to A850 with some interesting settings (including that 99%/60% diff.), so I took it back down to B700.  Without the slicks, the throttle control just got a might tricky.  I wasn't able to "steer" the car with the throttle in mid-corner like before.  And I'm afraid to even touch the brakes with that thing, unless I'm giving it some throttle at the same time.

   Basically, I still don't have the hang of driving those little beasts, and you wouldn't want to be on the track with me while I'm trying.     I dunno if I even want to mention the exact time; let's just say that I was close to 140.xxx when I finally gave up. 

   Then I decided to give the Batmobile a try just for kicks.  Built it up and put a basic F'dog tune on it.  I came to find out that the batwing isn't just for looks,  as I struggled without it, but the car felt a lot better planted after I added it on. 

   I've never run Suzuka much, and my previous times were in the 142.xxx range before I ran the CSL.  After about a dozen laps, I was down to 137.xxx with more available.  And it was a heckuva lot more fun to drive than the little "beastard".

Running yet another version of the 'bitchin camaro', I managed a 2:13.128 (133.128). It 's got more tire than Serial's Z, and a smidgen less power, but it's much better than my previous efforts. The latest Z breaks down something like this:

4.7 / 4.7 / 5.3 / 5.0
320hp/301 lb-ft/2549 lbs

[Serial]

Hop, I'm sure you obviously found my posted Z28 build/tune...but for those that haven't, it's posted in my garage:

http://forza-tuning.net/index.php/topic,549.0.html

I'll have to double check when I get on Forza tonight to make sure that nothing has changed since then...should be nearly identical if not exactly the same still.  I know the build hasn't changed at all.

[TheJohnNewton]

I just bought a Batmobile with a pretty paint job off the auction house and took it for a quick spin on Tskuba just to get a feel... It needs a lot of work! Lol.  Kind of reminds me of that other old BMW I have (the only other Bimmer in my garage) in that corner exit oversteer is a bit of an issue.  Well off to the garage...

[Hoplee]

Serial, I applied your settings to my Z28 and picked up 0.01g on both grip benchmarks, possibly due to the max DF setting. We'll see how she runs!

[Drift2XL]

I saw no rules and decided to try the slick route.

Then I find out that its DOT.  Rats.

I will say that my belief is that the muscle will be faster with the DOT's

I'm gonna post 'em anyways. But not counting. Call it a measuring post.

Shelby 132.253
CSL     132.334
Z-28    132.552
911 RS 133.489

The P-car was left over from the last one. With full LW and not much power. Too little power. Would need alot of power to keep up.

That's a quick Camaro, Hoplee.  I'm using a variation of Serial's Z/28, but I'm not having quite as good luck with it yet.  I turned in a 136.777 with it tonight.

BMW CSL
132.415

It's not Serial-esque, exactly, but it's a good little car, and it's in full-grip trim, save for the DOT's instead of slicks.  This is a new PB for me, beating out my slicked-up 2000GT.  I believe it's running more power than the Tiny Terror, but I can basically keep up with it in the twisty section, too, which means the wheel nut has tightened considerably.
