Re: Track Time

Nice pics, great to see the car NOT turned on it's side every sharp corner.
You guys have ruined me, I ordered the ancillary parts to install my suspension kit. It will go on after I have my dealer check out an annoying whine I'm getting around 60-70mph on the highway.

On the other hand, I've driven every track that I've driven previously on the stock suspension, so I'll have some good experience, plus laptime and speed data for comparison.

Regarding PF01/97--yes, the initial bite is less, but they REALLY reel the car in under sustained braking--suggesting that they like to be HOT. I'm considering partially closing my ducting w/ some tape to see if the extra heat keeps them in their nominal range (or gets them to the nominal operating range) faster.

I'm a noob so don't take offense to the question.
Wouldn't that also keep added heat in the rotors and wouldn't that be bad?

Re: Track Time

Yes the brakes will not cool as quickly--whether that is good or bad depends on both the track and the driver's braking style. Different tracks that don't exercise the brakes as much could use some duct blockage, other tracks could benefit from even MORE cooling. Same aspect as setting suspension differently for different tracks.

I have one track where I am definitely considering closing the ducts off partially. The PF01/97 combo gets very noisy when not warm enough, so that is one indicator that you can use. It's all about feeling what the car is doing and paying attention to wear characteristics.

Furthermore, there is some impact of thermal cycling--this could be what killed Gary's rotors so quickly. Get them very hot (braking from high speed straights), then cool them very quickly (another high speed straight after the braking zone), and you start to thermally cycle/shock the rotors. Depending on the track layout, this could affect the longevity of the rotors. Finding the sweet spot on this is more difficult to do, and there may or may not be anything you can do about it!

Re: Track Time

Wow, you can see how much less roll there is in those pics. Get my chance this Sat. at PBIR to try my springs out. Good thing since I know that track best. RA looks and sounds like a lot of fun, so many great tracks so little time (and money left over from all the modding :)

Jason, I sure your skills will catch up quickly. I have been driving much faster this year. Of course most of that is thanks to the Boss itself, even with all the little problems we talk about it is a very capable track car and one heck of a car to start with.

Has anyone run 08/97 combo? PFC tells me it is like the 01/97 combo but the 08 last longer.

I get it now. Thanks!

Bingo that's exactly what happens at Road America. There are three long straights where you hit almost 150 and drop down to maybe 50 or 60 so you are shocking the heck out of the rotors. Some guys were discussing partially blocking the ducts to avoid shocking them. I've never seen so many mechanicals as we had yesterday at a track. Several were brake related. I've also never seen so many rotor changes!!! Guys all around me were swapping rotors. ??? My pads didn't wear any more than normal even with the dramatic braking on slicks which exacerbates the energy transfer into the brakes. In fact I never got a soft pedal and never felt like I overheated them. It's just some wicked hard stops from very high speeds repeatedly. The other thing I noticed is three of the heavy braking zones are at the bottom of very significant hills which provides some nice camber to slow the car but also greatly increases the energy being absorbed into the rotors I would assume.

Re: Track Time

I cracked a rotor at Pocono raceway - top speed 155 in the straights down to under 100 in the turns...

Re: Track Time

Gary, what is the verdict on the combination of wc splitter, tiger hood, and ls wing? Did the car have enough rear down force at speed, or did the rear get floaty?

It seemed like I had plenty of downforce in the rear as far as I could tell. I was flyin' and I don't know the track, but the rear never felt light. I think next time out I'll have a better idea when I'm not so focused on learning the track and really cutting loose. The only thing that bugged me is the hood flutter I got a few times. It was generally only in the Moraine Sweep so could have been a wind direction phenomon. It was much more pronounced when I pulled my grille. Nothing like hitting 150 heading down a hill into a 120 degree left hander wondering if you remembered to refasten your hood pins after you pulled you grille Most of the fastest cars out there had wings above the roof line so you know I'll probably end up with one at some point Sounds like a winter mod ;D

Re: Track Time

Well your new aero aids are the WC splitter and TR hood. Did the front end feel planted? I would imagine the stock hood would flutter in the same conditions?

Yea the whole car felt great especially considering the speeds. I really left a lot on the table because it was solid, but given the potential consequences figured I'd give it a couple days before trying a "hero" lap. GPS indicated speeds were near 150 repeatedly. The stock hood would have frightened me at those speeds. It would have been fluttering like a butterfly with no "safety pins".

Now you have me worried again, my hood was dancing like crazy at Pocono @ 155 MPH... Whose pins are you using again ?

I got them from Paul Brown but they are the same style as Steeda sells (Sparco)? Since Ford tested and engineered the stock hood to 155 or higher you are probably fine but then again I put a couple on my GT500 hood for piece of mind too.

Yep.

Re: Track Time

The car handled like a dream. I was just amazed at how I could bring it downhill from almost 150 into 120 turns and the car just rotated. The brake dive was minimal even with the ridiculous amount of force involved late braking a 3600 lb car on slicks. There is essentially an uphill "S" from Canada Corner to turn 14 before the front straightaway that I could take almost flat footed and I picked up huge amounts of time on almost every car including the Vettes in that stretch. There's no way the car would have handled the transitions on the stock suspension with that much throttle input.

Re: Track Time

Told you RA was worth the tow. yes most people are slow through the uphill left hander after Canada. The GT3 on street tires was just a feather on turn in turn then full throttle up the hill. Fun times.

You were absolutely right.....so right in fact that as soon as we got home we booked another trip over there in 4 weeks with the PCA ;D

Re: Track Time

Love Road America!

I plan on being there for the Northwoods Shelby event at the end of July. It's been several years since I've been to this event but it's always a lot of fun plus it is a 3 day event. ;D
