John,

was the GMG GT3 cup the world challenge car? was James Sofronas driving it?

 

So a World Challenge GT car beat up all the tuner cars?

 

good effort guys at AMS!


competition is getting good... esp west coast

 

a car that comes from the porsche factory beat up all the tuner cars.. you want only slower cars to come out?

 

Nothing magical about the car.... over 2800lbs and i think it only has 450hp. Cool to see a porsche cup car compete in a time attack though.

This goes to show... its time that evo tuners start really tuning chassis and not HP

Any idea what caused the oversteer tendancies? Is this the first time with that wing?

 

I think it was their first time with the front splitter? Time for some more rear downforce!

Though the GT3 car only has ~450hp, it is a fully sorted out, pure race car. People have been racing 911's forever. Even with that version of the 911, there's probably tens of thousands of test hours and thousands of race hours worth of knowledge.

 

I'm sure it was that 40/60 center diff

 

Porsche factory racecar... yea.. we have about 30 years of development, factory development, to catch - and that's a factory that builds that car to go race. Ours is a 4-foor family car. AWD is good, but I still stand by the fact that if you want to go fast, really fast - the answer is mid-engine rwd. I am honestly not going to feel bad about getting beat by a Porsche factory race car.

What I do wonder is when the Super Street guys will go ahead and say "no flat 6's" the same way they say "no pushrod V8s and such" - cause otherwise it would be a Porsche Corvette shootout.

The oversteer issue started when Daddio was at VIR last month, he told me it was wicked, and the wing that's on the car is brand new.. the splitter we have been running off an on since One Lap, so that's not the issue. (though lowering and playing with the car and getting more downforce out of it has) We had the GT500 wing on the car, and thought that it was probably too much drag for the amount of downforce it produced. We went with the modified OEM wing, which didn't work, now we are on this one, and it still doesn't seem to be helping.

I am also no convinced it is just the wing, because of how it changed during the day despite us making changes. (for instance early it was only high-speed, in the last session it was everywhere.

On one hand it's kinda cool, this is how you make progress, and it's an aspect of motorsports that I love - not the losing part, but the progress part. You try something, it works or not, and you go from there.. make another change, see where it goes, etc.

Is it good to have public R&D.. not usually.. The "bad" results tend to stick in people's minds. Not that the results are bad, but that they are not what's expected.

Acura is going into ALMS, and they won't even let cameras in for test sessions, Audi struggled for a while a few years ago in prototypes before being a 1:1 odd on winning event's it participated in.

It's easy to look at a car that wins and say "wow they built a great car" but with any winning effort, and even moreso the higher the competition gets - successful efforts are built on days like yesterday. Sorta like Thomas Edison said: "I didn't fail 1000 times, I found 1000 ways not to make a lightbulb."

There is no 60/40 diff in the car yet actually, that's an off-season project along with a dogbox.

 

Jon,
As you know that is all part of racing. Good job keeping it upright even with the sand, it's easy enough to do something stupid after you're in trouble and really wreck a car. In this case it sounds like coming back with the car mostly in one peice was trophy enough. I'm sure Martin is at least happy about that

Marty and I are heading to VIR next weekend (18/19) with intentions to do additional sorting on both of our T2 cars. To bad the TA car is so far away or you could continue the tweeking and maybe get a few hotlaps in. The offseason ends in January this year as we start with Sebring...so upgrades and sorting before that will be limited.

Good Luck sorting that beast out...maybe the ole' wing needs to come back...if not there is a Honda in the parking lot at work with a HUGE plywood wing that should get the job done

 

They sold the old wing.. doh! I think we can get it, it will just take work.

The spin thing.. I feel bad i cracked the splitter and ripped the side skirt off... but.. Since our first test day in Feb of 2005, that is my first spin in an AMS car. I have been damn close and had some scary moments, but that's the first time I just flat had it get away from me. (and it happened twice in one day)

It was actually liberating in a way, finally getting it out of the way, and not hitting anything.

I still wish the results could have been better, more indicitive of the effort the team puts in. The car ran great, the guys put a bunch of time in making sure it was ready to go, and really it was, we just missed the setup as they say.

It was really awesome being out there running against the cars on the west coast, and seeing that many fast Time Attack cars in one place. I am really looking forward to getting the car better, and running against them some more.

 

So was Vesko and Competition Associates the fastest Evo again this year?

 

I didn't even look... I was happy I got to a 55, and saw we were 8th or whatever in class.
