We finally made a 1/4 mile pass....

Anybody feel like being our valvetrain, connecting rods, or driveshaft U-joints?

See incrementals in photo.

Dad burned the brakes off the car trying to stop. Keep in mind it's a 3000 pound car, and we know the brakes are on the small side since he barely gets stopped at the local track running 1/8 mile. He blew past the first turnoff (1,000 feet), then the second turnoff (1,900 feet), and finally got it slowed down, and took the turn-off at the sand trap (2,700 feet). Both rear brake rotors were goldish-brown and deep blue when he got back, registering north of 450 degrees even after the long trip back to our pit. We've already done 2 brake pad changes this year, and almost due for a rotor change.

Probably would have been a good time to test the parachute, I'm thinking.

Prolly a good time to upgrade the brakes (or get an anchor.)

 

[TexasRaceLady]

Yep. I think a parachute test is in order.
Did your dad's underwear hold up?

 

[Magnethead]

Yea. Said the car stayed glued (yay for the pro-mod wing), but he thought the hood was going to come off. We have the scoop sealed tight, and their was more air coming in than the motor could inhale. When the butterflies closed, said it came up about 4 inches.

A chute test has been in order for awhile now, just haven't done it. Turning that RPM, won't be going quarter mile anytime soon anyways.

We've got single 4-pistons on each corner. We're on a hard compound, we tried a soft compound earlier this year and it just chewed through the pads, only got 4 races out of them, they stopped a little better but not much.

When we put the brakes on the car, they had "2800 and down" and "2800 and up" packages. We went for the 2800 and down, to save 25 pounds. The car is 2960 with dad in it, and with the ET/speed, clearly not enough. I've been wanting to go to at least a dual caliper setup. Most cars run 2 independent braking systems on the back axle, one system with the hard pads hooked to the front as usual, and a hand-brake with the soft pads. We have no room for the hand-brake handle though.

Woo, that's fast man. I've driven 11-second cars on a pass, can't imagine driving a sub-9 car. What kind of car? Pro Mod you said?

68 camaro.


It's not a promod by definition (they go in the 6's), but alot of people think it is because the wing is designed like a PM wing- lots of deck area and sizable spill plate [PM spill plates are huge, ours are mid-sized].

3rd round of eliminations was run at 2:00 AM when we lost, the finals were run at 3:30. Very much an overnight race, but that's how you do it in the texas heat.

We built a big motor for this year, and knocked the front end off the first time out- made more power than we expected, and the track held every bit of it.

Where did you go? Motorplex???

 

[Magnethead]

Where did you go? Motorplex???

yes. Gates open at 5:30, time trials at 7 and first round around 9:30. Aug 3rd, 10th, 23rd, and 31st....every saturday this month except the 17th basically.

Had 66 electronics entries, 44 footbrake, 24 footbrake quick, and 32 electronics quick.
