Race Video - 951 LS6 vs heavy hitters in the POC
This race is from last Sat at AutoClub Speedway in Fontana.
Porsche Owners Club (POC) Red Cup Race 6.03.1012
The car did fairly well. It had an low/medium speed oversteer condition that I couldn't dial out with what I had at the track available to me. This due to the difference from having a transaxle fluid with friction modified vs transaxle fluid without.
The funny thing is that the car had a push condition. Just the fluid change with the friction modified dramatically changed how the differential worked.
Some of those 911's are just stupid fast and make my 460RWHP 951 seem slow.

What kind of speeds are you hitting on the oval? The hood looks like it's going to shake off.
Tony, I debated for a while about actually typing this, but I just don't understand. I do NOT want to offend,but it's killing me. Your set up should make all the power your Dyno says. It's almost silly to think otherwise so I will stand by your numbers with you! But here goes. I'm watching the G meter in acceleration. You should be pulling well into .75g's with that power to weight. I'm only seeing high 5's. I don't understand why you aren't accelerating violently. I hear you short shifting in many areas. But you are clearly accelerating at full throttle. Why not a stronger pull? I figured maybe the G meter is tilted or something to give false reading, but your stopping looks on par. I'm listening to your revs and they just aren't climbing as fast as they should be. Even with slicks, second should be almost pointless and third should be like most peoples second. Are you rolling on the throttle?

It's all good. I hit about 165-167mph going into the oval. Lift a little, then back on it.
I short shift in some areas because the car wants to oversteer on hard acceleration. I took out 200lbs out of the rear springs, then tightened up the front bar, then lowered the rear of the car about 1/2". It helped... but I wasn't able to really get on it exiting the turns. More so a problem turning left than right. I suspect an alignment issue but until I get it on a rack I don't know for sure.
One thing you have to remember... every body on that track is running new slicks. I run NT01's.
As far as power goes... go lookup the specs on the 2012 Porsche Cup Car with a World Challenge engine. That's why I can't pull on these cars. 460+RWHP at 2900lbs with a no-lift shift trans, gigantic brakes, huge slicks.
I don't know about the G meter calibration. It might be off.

I see a lot of early braking and late on the throttle in quite a few places as well. Anyone can dyno big numbers with the car strapped down but not many people can handle WOT around the track, especially if they don't have the skillset/practice to catch the car in an oversteer situation. Basically, money != skill.
The late throttle was due to the fact that the car was substantially oversteering on slow/medium speed exits. This was worse on left turns than right turns. I don't know the reason why because I've not had it on a rack yet. I tried to dial it out by taking 200lbs off the rear spring rates, disconnect the rear sway bar, stiffen up the front sway bar, and lower the rear ride height. That all helped a little... but it still was preventing me from planting the throttle hard on corner exits.

Just going through the specs here, but what brakes are you running? Rules limited? Tire question is above. Your weight is 2500lbs right?
Well, good luck on getting that limited slip issue taken care of and please post when you find something. It helps a lot to stand on others shoulders in here.

Allways enjoyed watching your videos Tony. good times! 
It's hard to be driving ***** out on the NTs when everybody else is on slick. Nice representing the lowly 944 amongst those 911 albeit with the LS beast of your own. I was watching a bit of of NASCAR this past weekend where on the main straight at Dover, those guys were doing 170mph so your right there with those Sprint Cup cars.

You only run NT01'S!? Any plans on running something a little stickier like Hoosier R6's? And man that's ballsy at that speed and those G's. There's a chicane further in that I can tell you love to point and shoot through. Pretty slick driving there.

And yes... slicks are in the works. The reason I don't run slicks now is that I can't get a slick wide enough in 17".
Since I have a full wide body kit (3" wider front, 3" wider rear) going on soon, I'll wait until that's done, then order a couple sets of wide 18" wheels so I can run big slicks.
And yet I have big brakes now. I run 996 GT3 14"/13" brakes. They run 15"/14" ceramic brakes on much stickier tires.
I weighed in at 3014 after that race. I started with a full tank, ran 15 laps + 2 warm up laps on a stock 21 gallon tank. So there was probably 7-8 gallons in the tank at 6lbs/gal.

Here's the deal. The car pushed bad the last time out under the same circumstances. I changed to a different transaxle oil with friction modifiers and the thing now did the opposite... no other changes. Same tires.. even a new set of the same tires.
The rates are 750lbs front/1000lbs rear on custom valved Bilstein Escorts with a weltmeister front bar.
The 315's aren't too wide. The car got faster every time I went up on tires size. That's how I got to 315's.
In fact.. the car is going to be running a 320 front / 330+ rear Yoko slicks with a considerably smaller wing after I get the wide body kit installed.

All you armchair quarterbacks that think Tony should be faster etc. haven't driven against those guys, in those cars.
I have, and thought Tony was doing fine especially considering the huge tire handicap. It's an old car. "Those guys" have new ones. They're better. A LOT better.
Tuning the chassis to work in the slow infield as well as on the banking (where it absolutely has to be right, or at least close) isn't that easy.
