Wow, that's going to be a little tough to have to run that weight and be at the top of the time sheets.

As a data point.....my car was 3020 dry when I sold it. So 3220 with me and no fuel.

ukrbmw

That's about right. Car is weighed with driver as it comes off the track. This is also why I was trying to stay away from the slicks, no penalty so you can pull a little extra weight out.

I've only seen one down at 325, the normal range is 340-355 RWHP.

The parameters of TTS and ST2 (my race class) are identical. Slicks incur a .75 penalty, and there's a weight penality under 3150, a bonus for being over 3300. You could get a bonus of .4 if your largest tires are only 275's.....

Using my car as an axample, starting at 8.7 I add.75 for slicks, and .3 for weight (2625) bringing my minimum multiplier to 9.75. At 270 rwhp that means my minimum weight to stay in class (TTS or ST2) is 2633 lbs.

I ran against Brad Safronas, James brother, in his just-built yellow GT3 at Willow Springs in December. They still have some bugs to work out, but he was just a hair slower and I expect him to give me hell next season with that car. He ran at around 3100 and dyno'd that day at 325. Add alittle HP and I'm in trouble.

So could a GT3 win the TTS title at Mid Ohio? Based on what I did at Miller (bleeped the Corvettes), and what I've seen of Safronas' car with minimal mods, I think it absolutely could....

Great explanation JR. Thanks

I had no idea what the GT3 dyno'd at but took a guess

Couple of comments. All IMHO of course.

1. Slicks are not worth the points in TT Run A6's you are after 1 hot lap usually the 1st or 2nd lap before you run into traffic.

2. The 6GT3 is going to have a hard time winning TTS, without a lot of $$$$$ and if winning TTS is your goal I would look for a .2GT3RS as it has more power and better gearing and is right @ the wt to hp for TTS.

3. Besides Full Suspension, LSD and the car really needs to be re geared in 3/4/5 and move 5th to 6th. Figuring 350 rwhp @ 8.7# = 3045#'s with driver which should be doable. Also Aero with a really good front splitter and Cup rear wing.

4. As others have stated the Nut behind the wheel has a huge impact on times and Danny Popp is surely a Nut with talent.

Of course all this assumes we have Common Sense when we plan our upgrades and keep emotion out of the picture.

A couple of comments....

#1). I agree that for TT's the A series R6's are the ticket. You still have to run at the limit of 8.7 to be competitive whether you drop weight or add HP.

#2). For power you just need the 997 GT3 throttle body which is much larger, and a GIAC flash. We've seen 385 rwhp on 2 996-GT3's with this combination and open exhaust. You probably don't want that much HP but it's there for the asking.

#3). Revalve the Bilsteins to match 900/1100 springs and get Guard's diff/clutch package. That should be under $2,500. The gearing is a huge expense and not worth it. OEM gearing is close enough.....

#4). Get pro coaching.....

My 2 cents,

This was my rookie year runnning NASA Mid Atlatic GTS4 and first and for most it was a blast and the NASA family is fantastic. My car started as a street GT3 gutted with Moton Clubsports on R6's, and by the end of the season I replaced the glass with Lexan not much else has been done. I'm down on power (330) and over weight at 3050lbs with a 1/4t tank of fuel (9.2lbs/hp) but I still managed a 2:04.9 at VIR during my last DE (2:05.9 was the best I managed during a race). I think the car is capable of a low 2:02-high 2:01 if all things are perfect. There is no chance of me keeping up with Wally or Paul's 430 unless I modify the engine significanlty. Any particular reason your only running Time Trials? Come join the ranks of GTS4 and help me fend off the BMW's!

p.s. I won the championship this year,

Guys,

thanks for commenting. This car already runs tripple motons with 1000/1200 and guards LSD. Not full cup aero, but that can be fixed. I think I'd rather try and pull weight than go for power, keeps powertrain more reliable and reduces wear on consumables.

I'm not the best driver, but do ok. With that said, new to 911 so there will be a learning curve. Sounds like I should be in the ballpark at least, and I'll keep my fingers crossed that One or two key people don't show

I have a racecar, run Spec E30 down here. We get great fields of 20-30 cars and dollar for dollar it is hard to beat! But I also do a good number of HPDEs and wife runs TT. Trying to find something to do both. Spec car sucks in DEs when every newbie in a new car goes by me like I'm sitting still. Again, not trying to win TTS nationally, just seeing where it would stand. I won't cage the car, want to keep it more civil.

LVDell

Don't underestimate aero! Getting the ride height down, the cup front splitter and rear wing will help tremendously.

jrgordonsenior

Agreed, ride height and rake are paramount....

ukrbmw

Vic's car has Cup splitter and 996RS wing - as I understand it's a bit more effective than stock wing, but not quite a Cup wing.

va122

Hey Alex, the car has the 4.0 R&P so you should be all set with gears. If I'd known you wanted cup gears, Kent could have done that for you while the box was open...

va122

I also have the RS nose with the downforce kit...ride height is pretty much as low as you can go without any ill effects. (Bumpsteer has been dialed out so no worries)

LVDell

Then all he needs is the cup wing and he'll be running circles around the guys at VIR
