  1. Thanks guys it's in the livery of the 77 Sebring 12 hour winner. I recent photo of the real #30 RSR now in Sweden. One at Daytona from a French Mag.
  2. My So Cal rainy track day video.
  3. Found a photo of the RSR+ on the website for my favorite Track club, place called the Thermal Club. Located in the desert near Palm Springs California. Perfect weather in the high 70s, no wind or or rain, typical weather for our deserts in the winter. Last weekend raced there for 3 days. (in my other race car) 2 Practice sessions. 2 Qualifying sessions. 1 Warm up session. 2 Races. https://youtu.be/zPpFJeITV_o?t=385
  4. We drove our 86 club sport to Rennsport at Laguna Seca raceway in California. It had only 100 miles on the restoration. Drove from San Diego to Monterey in 6 hours averaging 80 to 90 mph except for construction zones and a few miles in Los Angeles. Great drive, Gemini blue club sport was my wing-man Frank. My favorite Rennsport car the 917/30.

    Love laguna Seca, at 15:30 they lap me in the white Camaro. my view, start at about 23:30.
  7. Today old Long hood Porsches are worth more stock so it makes little sense to make mods that are not reversible. Perhaps in the near future unmolested impact bumpers may see the same demand and popularity. 20 years ago we started to modify our blue 69T (74 RSR look now) we did any and every mod possible for performance. Looking back I can't believe all the mods and fun I've had with this car while always keeping it street legal, registered and insured. No regrets, but now that its done and I've raced and tracked it for 2 decades I feel its getting close to time to sell. -------------------------------------------------- While the black 86 Euro was my work car for 20 years, it recently received a factory stock restoration. It's kinda cool to see it today looking just as nice as the day it was new. Plan is to keep the 86 a long time.
  8. You could just leave a GPS lap timer in your glove box or pocket to record all your lap times. https://www.aimtechnologies.com/car/aim-solo-gps-lap-timer/
  9. This is a sad track day video. Free balling it in his shorts and T shirt on the an F1 track, then after his hands off save he self congratulates himself with fist bumps. Points a 911 past then almost rear ends it, hands off again, then a slow spin hits the wall with his hands on the wheel.
  10. Patrick Long makes a 915 look like a G50.
  11. If you never go to the track and you never down shift aggressively you could survive with never learning to match revs on downshifts. Heel and toe is part of the fun of driving a manual transmission. The 911 and its clunky 915 trans axle react well to matched rev down shifts. Every mechanical part involved will last longer if you match revs on downshifts. New Porsches have automated match rev downshifts because it is valid. Imagine slowing from 100+mph and not matching revs on the downshift from 5th to 4th and just popping the clutch in 4th with the engine at idle. It would feel like you pulled up the parking brake except for the additional avoidable wear/damage to the clutch, syncros and gears. That said on public roads most of us see a red light a block ahead and just pop it in neutral and coast up to the red light. Or if you are in the mood you can practice your heel and toe foot work till you reach the red light.
  12. Thank you moderators for reposting this thread. lively technique discussion, I asked some other drivers about letting go of the wheel. It appears it is more of a drifting technique when transitioning from full drift to opposite full drift. fwiw consensus from a track day forum. http://www.trackhq.com/forums/f221/releasing-steering-wheel-letting-spin-freely-unwind-10358/
  13. Good stay happy, we all need to find the right driver that we want to influence us. Jack is a very nice guy I shared the track with him a few times long ago. I hear he is part time instructing at the Porsche experience test track in Los Angeles. It would surprise me if he is instructing new Porsche owners to release the wheel? Here is another video of a free spinning steering wheel. Like Jack my buddy Dr. Greg the driver in this video has decades of track experience too. I was told if you lose control on a steep banked oval turn to program yourself to just turn downhill and let the gravity from the steep bank help guide you down and away from the outside wall. But old habits are hard to break, here the driver releases the wheel at 120mph. Hands off it spins the steering wheel both directions several times, including spinning the steering wheel hard right towards the outside wall. That reaffirmed to me that a steering wheel released is not always your friend. How can you be sure when you release the wheel that the car will stay on track or off the wall? Debating the advantages of releasing the wheel fascinates me, I'd like someone to tell me which turn at what track is the correct place to release the steering wheel? When I was an instructor I requested my students to always hold onto the steering wheel, instructing or riding in a car with a driver that releases the steering wheel seemed an unnecessary risk. I have not seen the release steering wheel technique in use during any professional racing? Perhaps someone here can share video that supports or teaches drivers when to let go of the steering wheel?
  14. "mistake" is too harsh, since it is deliberate when you release the wheel I refer to it as a technique. Not only beginners but my peers amatuer racers release the wheel too. you and I shared opposing views on steering why take it personally? Technique is a person choice, we can share but should not teach technique. It's not uncommon, at 7:10 this 911 driver releases his wheel too. soon no one will be holding the wheel in our new self driving electric cars, its the future. Sladey I know we don't press the brake pedal the same either, but I still like you. Norty thanks for hosting this driving tangent. Hope it was just a leaky oil hose fitting?
