Justed dropped front and rear to 30psi, launched 1st gear at 6100 RPMs, feathered the clutch, short shifted 2nd gear than redlined 3rd, then got into 4th gear and ran a 12.49 @ 118mph with a 0-60 of 4.27 seconds. On STOCK TIRES!

Nice, much better ET and MPH. Is that on a gtech pro ,they do typically show 3-5mph higher as they recored actual trap speed while on the 1/4 mile track it is averaged between two sets of timing points at the end of the track (thus typically slightly lower).
Anyway, in 110deg heat I would say on a cool night at the track you will easily be able to ducplicate and most likely better that performance. Good job!!!
BTW how does your buddies C4S stack up to yours

 

Thanks!!! I never thought launching and running a 1/4 would be so hard. I have a lot of respect for guys who do it consistantly.

But the good news is the car is reaching its potential as I learn to drive it better.

With stock air pressure and poor shifts I was running 13.9-14.2.

Now lowering my tire pressure to 30psi and shifting better I got her to 12.4.

I'm maxing out the 225 and 265 tires though. With 245 and 315 tires and working on my shifts I will be able to get her into the low/mid 11's.

On paper she will run a 11.2.

502 Horsepower and the car weighed in at 3200lbs.

I have the power, just have to get it to the ground.

 

I think a high 11 is possible, i used to drag quite a bit (mustangs). I think your hp is a bit optimistic, powertrain loss on the c4 is about 17 percent (had mine and two others measured on a very accurate $800k system - incredible dyno facility). About 54hp was lost to the drive train, so your 402+54=456 or 402/.83= 484. Not tryng to split hairs or reduce your accomplishments, just trying to help out if you are using drag calculators to estimate ET and mph. I would say with a 1.6 short tme you should be in the high 11's at 120 or so. Very quick for a street car, must pull like nuts on the highway, these cars have great 3-4-5 gear power.

 

I thought AWD cars loss more than RWD cars. Most RWD cars have a 20% loss and most AWD cars are 25% of power?

484hp is still pretty damn good though!

 

The interesting thing I learned in my car is, I thought PSM worked by applying braking to the spinning wheels and reducing engine power so you can regain control of the vehicle?

I don't know if Vivid Racing/ Softronic changed that but my PSM works different!!!!

No braking or engine power reduction, just 100% traction to all 4 Wheels. I was doing AWD Burn outs!

If you watch my launch videos, I was launching at 6100 RPM in 1st gear and leaving 20-30' black marks and tearing up the road as I launched. The car felt great and I thinking even on stock tires I could get into the 11's but the shifts have to be PERFECT.

On my 12.49 run:
1st Gear- 6100 RPM Launch with PSM
2nd Gear- 5500 RPM
3rd Gear- 7100 RPM
4th Gear- 4400 RPM as I crossed the 1/4 Mile.

 

No typically an automatic may suck up to 20%, AWD cars usually around 15-17%. Like i said this was verified on a very very high end dyno shop with a facility you could eat off the floors, fully computerized, it moved all the air in the room every min or so, increadible place. Porsche drivetrains are fairly efficient, and in any event what you make at the motor is slightly irrelevent, its what the car puts to the pavement that moves it.
You have a stout car for sure. Getting the last few tenths is tough, and frankly i would be careful with 6100rpm lauches, the drivetrain was not designed for drag racing and things break. Bigger tires will mean the next weakest link will be stressed, i would prefer long black strips on the tarmac to broken half shafts and differentials.

 

I agree, I'm not using the car to drag with but right now just trying to validate the car. Once I know what she is fully capable of I will feel satisfied. Just after all I have done to her, I need to know what she can do!

I know the car is a Autobahn and Curve Eating Machine!

 

Some different times:

0-60: 4.27
60-120: 8.23
0-100: 9.33
0-120: 12.51
40-80: 4.42

 

Very NIce. I knew it was just a matter of hooking up and using different technique.

I think the best you could hope for is around 1.9-2s 0-60ft times to lower your et more. If you hookup with less than 1.8 60ft times with those hp levels, you're bound to break something.

Traps finally seem like where they're suppose to be.

Like the old Pirelli Ads go: "Power is nothing without control"

 

The other day all my runs where 1.9-2.1 for the 60'

I could believe what a difference the air pressure made, dropping them to 30psi made a huge difference and i was amazed that my PSM with working with me instead of against me!

 

My car is going to be featured in the SEP/OCT issue of 9Magazine. Got all done with the photo shoot for them and got some sample photos back from the Magazine, thought I would share a 5 of the 21. They did an OUTSTANDING job!!!

Any one is AZ/CA area looking for a professional auto-photograhper should contact Matt Chandler.

Also racing this weekend in a 4 hour road course event at Firebird Race Way against other exotic cars, super excited, it will be awesome!

 

looks awesome, except the exhaust is horrible! Why could the not hide ot better?

 

99-01 Narrow Body's have a different rear bumper which is smaller. I could have added a different bumper to hide it all but i like the piping, I have gotten lots of compliments at stop lights. The car looks stock until you see that, then people want to know whats going on. Especially when they see the down-pipe.
