I've experienced the cold tire/cold track lack of grip!

If you're going out for the first time -- how long do you give your tires to get some heat in them?

What tires? When I was behind guys with A6's within half a lap they were gone. Not sure about R6's. My 100 read wear feel best after about a lap and a half.

At Bondurant -- they told us that all the weaving back and forth was just a big waste of time... and that just rolling into the corners and the on and off the gas would heat the tires faster. I don't know if they just made that up or not - but they're all race car guys.

Track Junky 04-18-2012 06:33 PM

Not sure I agree with that. Cold tires roll over when your weaving and you heat the outside edges quicker. I dont weave to heat tires very often if at all just thought I'd comment.

So both you and your wife are going to drive your car at T-Hill?

From a motorcyclist's track day experience most organizers strongly restrict weaving. More crashes than heat gain is one and probably the primary reason. They say acceleration and braking will gain more heat than weaving.

BUT........we see most the big boys on TV weaving, especially F1. IMO - Any time you can create friction and carcass flex you're building heat. The key is doing safely.

At track days on the bikes I take it easy the first half lap and gradually ramp up the pace the next 1.5 laps, then it's as hard as I feel capable of pushing that session or day given the ambient and track temps. I run sticky DOT's and don't use warmers.

I can't remember the race but there was an F1 celebrity that lost it in the warm-up lap building heat in the tyres and took himself out of the race not too many years ago. :D

Good friend of mine did exactly that at Indy on the first lap. Lost his ride before the next race.

THAT is exactly why they told us not to weave! They said they have more wrecks from that than anything.... And that - as you stated - just accelerate and brake and the heat will come quickly.

Yes -- Gwen is scheduled for instructor ride along and I hope the car doesn't scare the crap out of her. It'll be quite a bit different than a stock SS Camaro...
The Mustang is "race car rough" and loud... and pretty powerful and rev's quite quickly... as in instantly. But it's fun to drive and I hope she likes the difference from a street car.

She's missing the DNA of "visor down, race on" so she should be fine.

If my wife was about to drive my car with a Jerico transmission at the track I'd bring a spare. :yes:

No --- That would be a REAL '66 R Code B Production Champion.... Mine is the clone.

clill 04-19-2012 07:01 AM

It's not a R model, just a 66 Shelby GT350 that has been a race car is entire life. Mid America B production Champion and New York State B production Champion in the for several years in the mid 70's. Fun car but still has drum brakes on the rear, manual steering etc.

Oops -- Sorry I lied.


So did you sign up for Buttonwillow? I can stop on my way down and we can take the '66 and a Busch car....

My buddy Bruce Leven has warned me about Jericos... and that they don't like "deceleration stresses". He's a fan of the Tex transmissions which he runs in his personal vintage race cars.

You can google Bruce Leven - Bayside Disposal Motorsports if you think he doesn't know what he's talking about... :unibrow:

Thanks for the info. I really like my Spec 25 M-22 bit if I ever go dog ring maybe I'll give him a jingle.

Mr: "Trash is Cash"!

My buddy is building a car for Bruce. Really neat vintage hot rod stuff.

I saw pictures of Bruce's garage. Wholly Smokes!

Normally he's having 2 or 3 or 4 built at the same time... it never stops...

ask him about Jeff Eischen. They worked together back in Bruce's racing days. Jeff isn't really a car builder per say. He was a partner in an Indy car team back in the day and an incredible fabricator. His attention to detail is insane. He builds one car a year and they have all been for himself except this one for Bruce.

Here is a link to a couple of cars he built out of his shop..

Now THIS is how you maneuver Thunderhill in a muscle car.

Good find Dave --- watched it a couple times and picked up a couple line changes!

I wish they ran turn 5 so I could watch him there instead of the bypass...

Can someone tell me what software was used to overlay the graphics on that video? That is pretty cool!

I think Gaetano said the bypass shaves 2 seconds on average?

Looks like you're right, I found it listed on his website. That system looks really cool, but it is a bit pricey...

Thanx!

GregWeld 04-25-2012 08:29 PM

I found other posts with that car / racing team -- with them running turn 5....

I can tell you right now -- that Charley and his buddies that are very familiar with this track - are running good cars - and making 2:11's or so.... He timed me on one or two laps and got 2:15 and I know I was doing way better than that on Sunday afternoon... but when I see this guy ripping off 1:54's --- it's like OMG -- no way I'm to going to be running like that!

I was hoping to get into 2:08's or better.... and have my GTechPro Fanatic RR all set and ready to go to clock my times. I'm mostly going to set it up to record the splits so I can break down the track and try to improve in one or two spots per session... then finally put 'em all together and see what happens.

Track Junky 04-25-2012 08:37 PM

You have to remember Dave Brown has multi championships under his belt.

What really amazes me is that he's running a stock front subframe. rear set up is LD

Yeah you can tell he isn't the average guy at a Run to the X event. :lol:

Speaking of, he should bring a car to RTTC next year and just clean house. :unibrow:

I like knowing he he is doing that with that stock sub. That car really isn't that exotic or crazy at all. Nothing that couldn't be driven on the street with the right gear. :lateral:

Now go get em Weld.

Vegas69 04-25-2012 09:49 PM

Clearly he is a great driver and his car is working perfectly. He's making a few HP too. :unibrow: I don't see him cleaning up at multi event though.

GregWeld 04-25-2012 09:51 PM

Ah..... the old "SKILLS" can outdo equipment any day....

I always refer to our beloved Mary P.... she goes out and lays it down REGARDLESS of what the car handles like.. she just adjusts and get's 'er done.


It always brings fond former memories of when I used to drag race - and you'd go out and kill some guy with far better equipment... but you'd do it with tire pressure - and timing - and the right A/F ratio at WOT.... just simple stuff that all the equipment in the world doesn't teach you.

I talked to Karl earlier this year at Infineon and I believe he said 480 to the rear wheels.
IMO it all boils down to wheel time. These guys have been racing for many years consistently.

Vegas69 04-25-2012 10:13 PM

That's the thing with the multi events. You don't have much time to figure out the course, let alone memorize it. Road racing is repetition and once you find the lines and set up, you can shave some serious time. Not taking anything away from him, just stating the facts.

Flash68 04-25-2012 10:19 PM

All true points. And my comment about RTTC was not very serious. :cheers:

Yeah it's a dry sump 387 making "only" about 600 crank hp.

Vegas69 04-25-2012 10:36 PM

He's got it in the sweet spot because it's motivating that car plenty. I bet it's in that 3100-3250 range.

Track Junky 04-25-2012 10:43 PM

Fiberglass front end and doors. No side glass and lexan. I think he said 3100.

Vince@Meanstreets 04-26-2012 12:06 AM

its all about being consistant and hitting your lines right. Chicca's Camaro kicks ass

thats what makes auto x fun, you don't usually get enough runs to memorize the layout. It mostly comes to driver instinct and setting up the car right. You can only get so much walking a course...unless your a Pozzi.
