Challenge Stradale lap time at Laguna Seca

the question is invalid

 

Not sure why its an invalid question. 430 Challenge times are 1:32-1:33. I'd say 7-10 seconds off that would be a good CS time. I'm sure someone here has actual lap times.

 

See my sig...

My experience is that the differential is different for different tracks.

I'm not 2 seconds slower in an R8 on a 2+ minute, 3+ mile track than a CS, especially on street tires.

 

I know how to rig the exhaust bypass so it's always open, but curious to know how to keep them completely closed?

 

Prepare the car, hire a professional driver, wait around Laguna Seca for the perfect day for the perfect weather and let us know the outcome.

 

There are some pretty smart guys on the forum. It is reasonable to state that he wants to know the best time with a stock car, with stock tires under ideal conditions. I'll bet someone here could peg it within a second.

 

Interesting. From experience, there seems to be a slight lag in performance with the bypass rigged always open, too. I've noticed this from driving several CS's with the bypass set to open. Apologies for highjacking your thread.

 

I've heard the same due to the ECU amending fuel levels.

 

Somebody please explain: Laguna Seca is located in a natural bowl up in the hills, far from any settled community. Why on earth should there be restrictive noise limits for such a race track?

 

What are you talking about? There is a vast number of homes in the area.

 

I'm gonna go out on a limb and say that a very good (race licensed) driver could get in one lap at 1:40 flat before the "stock" tires grease up and lose bite.

As far as sound goes: Not only are there a lot of people within sight of the amplifying bowl of Laguna Seca (Dry Lake) , there are also many wealthy people who don't like the sound of car racing or the traffic from the races. Fighting against them is SCRAMP, an all volunteer charity organization that runs Laguna Seca. The odds, as always, are tilted in the favor of the wealthy people with lawyers.

"What are you talking about? There is a vast number of homes in the area."


Of course, the track was there first, but that doesn't matter ....

 

...owned by attorneys or those with attorneys on their speed dial.

 

tires matter. according to top gear the CS was faster than the f430 w/ the stig driving. ferrari techs explained it due to the pirellis on the CS were better than the bridgestones on the f430.

Because some knuckle heads built houses, knowing full well there was a race track and then decided to moan that their pristine view now has race car sounds...... and the tree huggers that run the cities around laguna put noise limits to make them happy. You gotta love Americans.

Remember when we were at Imola and Monza? Both tracks are in the middle of cities, with homes within yards of the track, and there was nothing but smiles.

 

Is it mounted where driver can get at it? Only activate before 5 and then open it up after T6? FWIW in my Porsche track car...3.9l w/ slicks I ran 1:38.6...BUT those sound restrictions just KILL that car. If I could run open exhaust, I'd be AT LEAST 2 sec. faster. I REALLY need to find a new muffler set up for that car.

 

PFFFT...slicks are zeroed out by the muffler, trust me! This is in Aug . The guys I was duking it out with are nowhere to be seen at Cal Speedway, Buttonwillow or Willow. 1:40...on the face of it on streets, sounds like a good time in a heavy car. But you can do better ...go get 'em!!!

 

On the stock Pirelli Corsa System I doubt the 360CS can break under 1:41 driven by a Pro.

Johannes Van Overbeck drove a 2007 997 GT3 RS (much faster car at the track than a 360CS) and lapped at 1:39.5, running on stock Michelin Sport Cups N-spec (235/305). Another pro drove a 997 GT3 on stock tires at 1:39.5

The 430 Challenge has several advantages, the Pirelli Slicks should be good for 4.5 secs at Laguna Seca compared to the stock 360CS/Scuderia Pirelli Corsa System. The 430 Challenge is 250 lbs lighter than the Stradale, has a better suspension (stiffer), no rubber bushings, stronger differential, and the power from the F430.

My guess is that the standard F430 on Corsa System tires should be able to run 1:40.0, and the Scuderia should touch 1:38.5. These are times that a Pro should be able to get from these cars.

I have some data from a few Porsche GT3 and GT3 RS drivers at Laguna Seca, but haven't taken the Scuderia there yet due to the 92dB limit, which I think I can fix with an easy mod.

Now, switching the Stradale and Scuderia to slicks, could give these cars a drop of 4.5 secs at Laguna Seca, but that would require stiffer springs to prevent running on the bump stops.

A 1:43 lap with a 360CS on stock tires at Laguna Seca is a very respectful time for a non-Pro driver.
