Good luck. A 2900 lb Z06 with driver has to be a very difficult car to compete against...especially with a (totally unfair IMO) .5 penalty against you.

One thing that may have mattered was the Feb run was on 93, and these runs were on a 50/50 mix of 93 and 109. Since I don't have a race file, I'm not sure how much of a difference it would make. I hope this doesn't mess up the comparison:(. Thanks for the congratulations everyone!

Heavy, both runs were at my posted weights at the time. I think I was at 3303 in AWD and now, in RWD, I'm at 3215. Both runs were at the 1/4 tank allotment you have provided in your threads.

Does this put me in the lead for k16 cars?

What was KPG's configuration when he made the 7.93 run?

Ryan

Shoot. The fuel probably did make a difference, although I don't know how much.

Any way we can get you to get some dyno runs on 93, and then on 93/109 on the same dyno, same day;)

Oh and yes....you're in the lead for stock K16 cars!

I don't know if I'll be able to find time anytime soon.

One is north of 600 whp which confuses me as to how it's in the same class when the weight/power ratio limit is 5.5 (And that is closer to 4.5)

Even still I'm not far behind. I'm going to keep my car RWD when I got to Barber Motorsports Park in a few weeks and see if it helps on a tighter circuit, while the AWD helps in high speed turns, it's the slow stuff that makes it struggle.



One question though, how much of the front diff is unsprung? I dont want to take it out, but the rewards are too great (weight loss, points gain, no power understeer)

Wasnt there a DIY somewhere on here for the RWD conversion? I took my shaft out for the dyno next week. If I can borrow Al Norton or Manalex's Performance box I will do a 60-130 test 3 fold:

AWD
RWD shaft removal only
RWD complete removal

Maybe it will shed some light on the problem I was having with the shaft removed only. I'll do all three in the same spot.

This is if I decide to remove it, which right now, it makes life much easier in getting to my weight to power goals.


Also, no response, on the unsprung weight? Is there any of it unsprung or am I putting a big dent in my front rear bias ratio?

Sorry Dez...just saw this. AFAIK, everything you remove is sprung weight.

As far as the DIY, is this what you were looking for:

KPG's run was probably verified by KPGhilarioushilarious.

So we have .82 difference in the two runs on different roads using
different gas on different days. Is this correct.

I am hopeful this is statistically significant, but I do not know for sure.

MK

The road really doesn't matter. The slope and weather conditions do. These slopes were almost identical...and the weather was actually better during the slower run.

The difference in octane during the faster run, however, may have a significant effect. Not 100% sure though, since he doesn't have a race program optimized to take advantage of better fuel.

Like a big difference? Do our cars respond that well to different fuel?

Either way, I dont care, I've been wanting to step up to the next level of difficulty in driving anyways, I get tired of asking myself if the AWD saved me when I get crossed up and make a big save. I'm starting off without the LSD, but will add it in a month or so. And soon I'll be going ABS/PSM less.

Where is the info on the LSD?

Scott,

I was not actually mocking the results, I would love to see another comparo!!
this is good info you are seeking out and compiling for us. I have seen how
much more efficient a GT2 is at putting out power with the same (or lessor)
mods as compared to an AWD 996TT!

MK

Hey bro,

I didn't think you were mocking anything. I apologize if came across that way in my post.

And ya..you're definitely right about the GT2's. Less weight and less drivetrain loss makes them really quick with only a few modifications.:eek:

I know they do if they are tuned for it, Dez. But I'm not sure how they respond by just using better fuel and not advancing timing or increasing boost.

Here are some threads for you to peruse:

Finally got my GT700 Cayenne out for some 60-130mph runs. Best time was 12.69 seconds on 2.95% slope. PSM off started at 50mph, hit the gas and let the tranny do all the shifting. Car had to shift right at the end around 127 mph. Conditions were 50 degrees with average pressure and 80% humidity.

60-100mph was 5.64 seconds, while 100-130mph was around 7.05 seconds. The car really hits a wall once into triple digit speeds due to drag.

100-200km/h was 10.61 seconds. Stock 100-200km/h time for a Turbo S is 13.9.

Sent the file to Scott for verification.

Nice job, Aaron. You beat Peter's stock IS-F.:D
