This past weekend was the Weatherly Hillclimb and Hyde took 1st place in SM2. Unfortunately I did not surpass the previous SM2 record for this hill set by Hyde in the fall.
The record from the fall was 60.0 and I got down to a 60.2 on my last run.
I was running extremely conservative all weekend as the road was extremely slippery and my intent is always to drive the car home.
I was also held back a bit by the slipping clutch. It only slips when "insanity power" gets put down so going WOT was proving fruitless on some of the steep parts. I actually ran the 60-second pass using 3/4-throttle. I may fabricate a throttle stop until the twin disc clutch gets installed.
60 seconds over a 1 mile course ... that's a 60 mph average speed :D
Not too shaby when you consider turn 3, the wall, is posted for 5 mph.
I am waiting for the results to see how Hyde finished over all in raw times.
Anyway, here's the fun stuff:
Cin shot this with her little point-n-shoot camera that takes short videos with NO SOUND. I was launching soft because of the clutch and I missed 2nd gear .... but watch how Hyde takes off after the first telephone pole!

This is filmed with the Chase Cam mounted in the front bumper where the p-side fog light would be. This was from Saturday when the course was very slippery. This is a 6 meg file, but it is "internet resolution." For me to share this high quality it would have been close to 30 megs! I love this Chase Cam set up ... it's truly awesome.
Video #2http://www.jekylhyderacing.com/images/Hyde_Weatherly_hillclimb_Chase_Cam.wmv
This is my last and fastest run of the weekend (60.2). I was much more aggressive as the sun was out and the road was coming alive and there was a lot more grip. With grip comes confidence so I went for it on the last run.
Video #3 http://www.jekylhyderacing.com/images/Hyde_Weatherly_hillclimb_Rollbar_Cam.wmv
Incidently, I was intentionally trying to not get "big air" on the jump this year as I destroyed 3 rear swaybar endlinks during my last 3 visits to Weatherly :( |

The wide-angle lens adapters are really inexpensive ($20-$25 US).
Yes, I'll check better in next days. It could be a boost leak, but I read of guys with Profec setted at 40% or 45% to reach 1,1 bar of boost, infact before today I wondered about my low duty cycle numbers.
Really so cheap? Well, I can pay it...  |

Do you have an external or internal wastegate?
Also, you can get a wide-angle adapter that will fit onto the lens of your video camera.
It shows a lot more in the image (you can see your steering wheel & shifter).
They look like this: http://www.raynox.co.jp/comparison/images/video/ring1.jpg
I have a TiAl 38mm wastegate. Today I repaired EGT sensor fail and understood low boost response. Just I had to set GReddy Profec again after I removed turbo two months ago... 
I don't know exactly what's happened, just I know before that work my LO setting was 20% duty cycle (1,2 bar) and my HI setting was 25% (1,4). Today I had to set a 40% duty cycle rate to reach 1,2 bar! 
I like wide angle lens! I have to ask about price...  |

Sorry Jeff, right links should be:

http://www.tij-mr2.com/clips/Pergusa%2017-06-2006%20-%20due%20giri.avi
I've got a problem with my PC, so if these links don't work you can doenload them from www.tij-mr2.com/videoracing.htm
Bye!

Hi Jeff, here you can find two clips of my unlucky day at Pergusa.
http://www.tij-mr2.com/clips/numeri.avi
http://www.tij-mr2.com/clips/duegiri.avi
In the first one some "number" trying to understand new Rotora brakes (by the way they're cool! ), in the second you'll find two laps of track.
Again I got a turbo boost trouble. Profec has setted to 1,2 bar max boost, but at beginning I was unable to get 1,0 bar. Lap by lap boost decreased to 0,6 bar. Surely this boost losse was from EGT thermocouple fail: it got out from exhaust header and left a large hole in its place...  So I had to stop my race again...
Anyway I have to know why my boost is so low from start. It's second time I lose a lot of power due to unexpected low boost...  |

Between that piece and my new alignment, my turn-in is much better.
That piece also makes adjusting caster really easy.
I think you lose a little weight with it too.
If you contact them, tell them that I sent you :)
Thank you Jeff, it seems to me an interesting tool. Unfortunately at present my budget for TiJey is near to zero euros
I think next modifications will be scheduled for fall. Thank you again! |

Really? It's funny...

As for the alignment, for the last 4 years I just ran factory specs for alignment.
My tuner suggested the number that I am now using and I am very happy so far.
Today I test TiJey on the road I usually run. It was a surprise! Now the car turn and I have not savage understeer. Good numbers! |

Hyde's pistons are 9:1 compression.
Hyde's only other videos so far this year are from autocrosses.
These are really tight courses set up in parking lots. These courses are so tight and have so many turns that I almost never make boost. I go to these to test my suspension and brakes to make sure I am safe on the hillclimbs.
Here are a few:
Course #1 In the rain, bumper view: http://www.jekylhyderacing.com/images/hyde_autocross_NEPA_SCCA_6_4_06.wmv
Course #2 from the roof: http://www.jekylhyderacing.com/images/Hyde_Autocross_NEPA_5_28_06_B.wmv
Course #2 from the door: http://www.jekylhyderacing.com/images/Hyde_Autocross_SCCA_043006.wmv
Course #3 from the interior: http://www.jekylhyderacing.com/images/Hyde_Autocross_SCCA_043006.wmv
9:1 is cool! Definitely Hyde will get a lot of horsepowers in low range with a full fine tuning.
Thank you for new videos. Who's that one on passenger side?
Thank you for alignement numbers again. This morning, before to set it right, my mechanic tested TiJey on a hillclimb road in my town and said me: "I have seen death with my eyes, I was going to crash your car against a wall"... Then he setted alignement and tested car again on the same road, but this time his phone call was more relaxed: "All right Dario, you can drive this saturday". I'm very curious to test right alignment and new Rotora brakes on track.

I actually have a 2.139, not a 2.2 :)
Here is a video of a twin-turbo, all-wheel-drive Audi ITE race car doing the same hilclimb event.
He was 1-second faster than me on his clean run. On this run, he forgot his hood pins and the hood comes crashing up :(
http://home.comcast.net/~audibmw/weatherly.htm
I understand. By the way is great you feel more power in the bottom also without full tuning and cam setting. Do you know your new compression ratio?
Really did Audi driver forget hood pins? Well, he was lucky the hood has open in the slow...
Other videos Jeff? |

Toe .4 in
This is Hyde going over the jump at Weatherly last weekend:
Thank you for alignment data, Jeff.
Sorry, not GT30. It was hybrid T3/T4 or so, I really forgot your past setup My new question: GT35 with 2.2 displacement vs old turbo and 2.0 displacement. What are your impressions about low rpm response? |
