Congrats Rage2, you're an inspiration! Any dyno tests in our future? I'm guessing you're around 350rwhp @ 18psi or so?
Hey how do you have your blow-off valve hooked up? It just drains to atmosphere when you shift? No recirculation?

103 Octane race fuel, 20psi (holds from 3500rpm till 6750rpm), no knocking or pinging... Life is good =). Didn't get a chance to read the injector duty cycle, will get to that tonight, as well as 1/4 mile run at my usual spot. I want to turn that boost up more, I know the engine can take it, but there's really no safe place I can do it except on the track (which is closed till April).
I've scheduled for a dyno run next Thursday, so I'll know how much power the car's really making at that point.
And for my blow off valve, it's venting to the atmosphere. SDS runs off a MAP sensor past the throttle body, so it hasn't measured that air yet.
I'll update with some pics AND videos tonight! There's a car meet in town that I'll be attending so I'll snap some pics and vids of the car in action.

This post is really exciting! Can't wait to get a glimpse of the visuals later tonight either. I'm most impressed with the mileage on the car, I've got the same miles on my 968 and it's got a bulletproof engine and clean body so I like hearing of another high mileage car running so well! -Trevor

Fried Chicken Fred,
Yes, Don Salama is my brother. (If I say I taught him everything he knows about driving will you give me another star?!!!!)
Next season he is planning on changing from Speedvision World Challenge Touring to the Grand Am Cup racing in a Z3 Coupe.

Alright guys, here's some pics and videos of my car from tonight. Unfortunately, the weather did not co-operate, so I could only show the car in action on a lightly damp road.
The video clip has 5 sections. It can be downloaded/viewed here.
1. AVC-R 3rd gear run, low boost setting (14psi)
2. AVC-R 3rd gear run, high boost setting (20psi)
3. AVC-R 4th gear run (short), 20psi.
4. Outside view 2nd gear run (short), 20psi.
5. How it looked 5 minutes later...
On the #4 clip, you can hear the car bounce madly off the rev limiter, but the car still shoots forward at a decent rate =). Also note the unsteady boost levels, it's because I'm using a fixed duty cycle right now, haven't had time to get the AVC-R to learn the proper boost duty cycle yet. And for pics, you can see the rest at http://www.virgeweb.com/rage2/944t.
As you can see from the weather at the end, I didn't get a chance to do a 1/4 mile gtech run on 103 octane... as soon as it dries, I'll try again.

Excellent. That's how you soup up a car.
I'm looking at the Electromotive systems myself for the old 931. But way to go!
Hey, like, I don't mean to rain on your parade, but, like, did you take the pic of the 1.0 G corner with one hand, and steer with the other?
Just curious...

No, the G-Tech Pro holds the peak G force, and a passenger took that for me. To achieve that, I drifted around a corner really really hard (pretty much nearly spinning out).
Definately not a realistic measurement of my car's handling performance...
If I remember correctly, I was able to pull about 0.92g's around a long 3rd gear sweeper. That's probably a better indication of my car's performance.

If you thought the weather looked bad in the video, it was MUCH worse this morning. When I drove to work, there was about 4 inches of snow. Quite a few accidents, lots of people getting stuck. My little 951 made it through easily.

I only did 1 timed run. I pulled 100mph-130mph in about 6.8 seconds. Nothing spectacular compared to the Milledge 3.1L that pulled 60mph-130mph in a little over 7 seconds. YIKES! =)

Rage2,
119mph through the traps, with a stock bottom end and 180k on the odometer. That is awesome! The 993tt could only manage 114 mph through the traps. 959=116mph. I don't know what your car weighs, but if it's close to 3000lb., your must be near to the same H/P as a Porsche GT-2, hell maybe more. Outstanding, keep us posted when you run the 1/4 with 20lbs. boost.

My car weighs 2950lbs with a 1/4 tank of gas, we have some really accurate truck scales that are available to the public =). My friends have asked me many times to strip some more weight from my car (full interior, full sound system including sub box in trunk, A/C, etc...) but it's a daily driver. The whole point of this exercise is to make a daily driven supercar that looks relatively stock.
What trap speeds does your Milledge 540hp hit at 1/4 mile mark?

Rage2,
I ran 3 x 1/4 at the strip. Two @ 225kpa (approx. 18.5 lb.), on at 175kpa (approx. 11 lb.). The 11lb. was at 120.something mph. The two at 18.5 were 129.something, and then 131.4mph. I ran the G-Tech the same day and got 135.2. All of these were before the new cam. Temps were at 75F or so. Vehichle weight (Vineyard scale) 3020 with 1/2 tank of fuel. It's very tough to get out of the hole. G-Tech shows 0-60 in 4.9. Not going to win a lot of stop light battles. I run as much as 240kpa. That, and with the new cam I'd like to think I could get close to 135mph, but it's a stretch. We'll see. Motor was dyno'd at 520.9 h/p. In back to back on a motor very similar to mine, Jon picked up 22 H/P. That's were I get the 540. Ruined my clutch. Only running rear tires of 245mm (SP Sport 8000 with 34 psi). Far too much air. As soon as I get over the expense of the new clutch, I'll go to the strip again. The H/P makes it's biggest difference above 130, or so. Not really practical to all, but it won't stop pulling. I even tangle with the bikes. The one litres are usually scared above 120mph, or so. Don't blame 'em.
