Finally finished the intermediate lifters for the GMC. Machining this was a fun process, as I had to go through some parts till I got it to the point I was satisfied. The lifter will fit in the head and enable us to use a short push rod from the lifter to the rocker. In the picture the small lifter is next to the roller lifter from the engine with a quarter placed to show the scale of it all. I also want to thank Mike Kirby for doing the drawing and Terry Manton who prodded me to push forward and consulted on the project. Tony  |

Tony, what an intresting piece---I assume it is solid and it was mostly to address pushrod harmonics

Sparky, They have hole down the middle for oiling and yes, it’s for the harmonics of the pushrod. I have a mule motor that we run on the spintron, and you wouldn’t believe what goes on there. With the spring pressures, lift and RPM we plan on running this is one of the parts of our strategy to help keep valvetrain stability. Tony  |

Spintron? Tony, if not homemeade, what city and company is one located?

Lookin' good Tony, out of curiosity, where are you picking up pressurized oil? I take it you've added some sort of extra drainage ports to the head in between the pushrod holes (now that they're blocked).

Saltfever, One of my friends bought the spintron that Comptech had when they were doing the IRL motors at their auction a while back. He has it up at Sears Point, but is thinking of moving up to Lake Tahoe after the first of the year. He does consulting for some of the race teams and we squeezed the GMC mule motor in between projects. It sure is an eye opener.
Armond, Its not for pressurized oil, I have a spray bar on top and its to drain some of the oil that will eventually find its way there. It will drain through the push rods and lube the roller on the bottom lifter, and eventually end up draining to the pan off the drain down tubes on the cam shield. On the head I moved all the oil drain backs and shouldn’t have an issue with oil drain back. Trying to figure out the oil control on the engine and optimizing it has been a mind twister. But it’s been a lot of fun. Tony

It’s alive!!! It doesn’t look like much, but this is a milestone on the car as this is the first piece machined for the car (engine parts don’t count). This is the sump for the fuel tank with two –12 openings. Tony  |

It’s a little late as I was out of the country for the last month, but I want to congratulate Steve for engineering the new DP Flying Lizard car and helping it to put it on the pole for the 24hrs with a new track record. Tony

With the help of Woody we are getting closer on the final aero package. But still we have just as much to do on the aero as what has been done, and to quote Woody “The laws of diminishing returns are out to get us! But then laws were made to be broken!” This is a screen shot from one of the many CFD runs that Woody has done. Tony  |

"Got'Cha" was first run in 1974. Bill Temple entered both 2 clubs in 1976 with records in AA/BGR. At El Mirage 201.79 and Bonneville at 220.
In 1977 Greg Temple started driving "Got'Cha" and entered the El Mirage Dirty 2 club in 1979 @ 201.97. Greg went on to set two records at Bonneville, one in 1981 at 241.848, then in 1991 he set another record at 262.230
Bill and Greg were the first father and son to enter the El Mirage Dirty 2 club. They broke the D/BFR at Bonneville in 1981 @ 241 with top speed of 249. This record still stands today. In 1991 they set the A/BFR @ 262 which was later broke by Duane McKinney.

After a long wait we started working on the front sway bar and the rear uprights today. The wait was due to the steel for the uprights showing up without the proper certificates for the specs that Steve had called for. Tony   |

I had a pleasant surprise in the mail yesterday; one of my friends on the Renault F1 team sent me their last year’s style of pitot tube that was used on the cars. I have been contemplating on running a pitot tube to validate some of our aero work, and now thanks to him I can. Tony  |

Tony, You might want to do some reading research on a NICKS tube to use with your AERO projects. Very simple to make might help

My friend Larry finished up the mid plate for the GMC 302 / Aurora IRL motor today (the backside is a mirror image of the front). Slowly but surely the parts are starting to come in. The next parts to be finished will be the fuel tank / roll oevr valve and the rest of the bell housing supports. Tony  |
