I missed your first post about the LeMans cars, that's news to me but makes great safety-sense for endurance racing.
I wonder
A) how much their systems weigh, and
B) How much engine power is used to drive them?
Given the rather $$$$$$ and super-tech nature of that level of the sport, I'm willing to bet they trade some sponsors dollars for some pretty high-tech AC.
Listen: I've got an invitation (from a man who REALLY wants to make a sale to my company) to tour the home base garage of the C6-R, which his company is a sponsor of and resides nearby. I will add AC to the long list of things I shall ogle once I finagle the trip.
I'll keep you posted.

Keep the AC, you can always pull it out later. Besides, I've watched Mark A. jump into another 928 owners fully interiored 928 and extract something like 6 seconds off that drivers time. So as others have already said, you've got a long way to go before that weight is going to make any difference at all.

The holbert car is a race car, its driven almost daily, and it is one of the oldest / fastest race cars in the world. Its driven to the track, and without AC. you have to be careful about the fluids and keeping cool. I drive to the track in the early AM and on the way home , lots of drinks (not cocktails)
I do plug in a removable full stereo system too for the drive home, complete with sub woofer, CD player and tweeters in the removable door panels. I probably have as much driving to the track as i do on the track
the only problem i have, being so very low in ride hight, are bumps in the road and driveways.

All joking aside
I ran my current race car on the street for about a year before taking the deep dive. The ac didn't work, but I left the heat in.
Leave the AC and heat in while it is a dual purpose car. Once you are at a point that you feel you can really reduce your lap times because the car is holding you back, then drop the added weight.

With zero track time it's way too early to talk about mods. Drive it as is and make mods as you need them. Start with a thorough brake and suspension check and clean DOT4 brake fluid. That'll get you out there.
This is plain silly. Don't restrain the ego, dude.

yeah,that will get you out there for the first day! . the second day, i had put the suspension on and wider tires and wheels. then, after fully hooked, it was time to start with the power mods!
as far as being silly, what????
Its not the ego pal, its the miraclel car, for which we all are a part of with its amazing heritage.
Do you know of a faster older race car with the original engine in it?? I would be willing to put money on it that there is no car in the world faster and has more race time on it, in the world!
Point is, the 928 is an unequaled racing platform. even budget versions are getting big attention at the SCCA races now. Scot's (and his part euro 5 liter racer) has himself a 4th place car on a $2000 platform and a $3000 rebuild with $1k in euro stuff.

If you keep the A/C, I guess you should have all the cold air blow at you. You'd need (removable) insulation panels to keep the cold in the car. These would be nice to keep the noise down on the commute, too.
Hmmm...straight panels for the doors, with QR pins, and a heavy carpet/blanket to fit over the rear fenders/floor which would slip over pins welded to the body like the rear carpet does now.
OT, but, you haven't had the engine apart, correct? So the crank and/or cradle may have been modified by the factory for racing?

Brendan -
First, is the car going to be a "race" car, meaning wheel to wheel w/ SCCA or POC? Or a car you're mainly using at the track for DE's? It sounds like the latter.
I've found racing is easier than DE's when it comes to heat. Race weekends up here usually have one practice, one qualifying session & one race. You're on track at most an hour a day. At DE's you can be in a car as much at 3 to 4 hours a day. (Even more when I instruct.) Driving home at the end of the day when it's still over 100 deg F with windows open can be brutal. During that time, AC is gold.
As a SoCal guy you're going to be spending all your time at Willow Springs or Buttonwillow, which are a couple godforsaken hellholes where 105 deg F is typical. I'd keep the AC for now.

The conflicting part is that I may have to drive the car a while as a DD, driving to my appointments across the county, as the S2000 should sell soon, and the alternative is a 1995 Chevy Tahoe that measures its efficiency in Gallons per mile instead of miles per gallon!
The AC radiator, Compressor, HVAC fan, and HVAC box in the dash all weigh something. Quite a bit actually.
At my talent level for track time (uh, none right now), I am sure 100 pounds will make little difference, but a moderate amount of creature comforts could make quite a difference in the interim.
Any comments? Constructive recommended.

I am calling it a race car because other than some sound deadening, I am building the car up from Tub. I will be doing DEs with it at first, and see where it goes.

I also vote to keep the A/C.......you & I are in the same "rookie" boat.....it will take at least a couple years of DE's to get the a level where we could actually use a race-928 like Kibort-Dennis-Anderson-etc....so in the meantime why not have a comfortable 928 to drive to and from the track in! With the small possibility of daily driver usage....you gotta keep it...granted insane Diego weather is quite mild (compared to norcal valley)...but the two tracks you'll drive at the most are a bit on the WARM side....a bone stock properly running 928 is ALOT of fun on the track....mines even an automatic and it still flys around the track.....the trick is to get out there and get some seat time! I'm sure Jim Bailey will volunteer to be an instructor for ya.....kinda like what Dennis does for me!! Its sure nice having a top 928 pilot in the seat next to ya telling you the lines-etc!! :>)
