Guess my timeslip
Posted: Tue Mar 27, 2012 6:49 am
Well, the Malibu rebuild is coming to an end and in the next couple weeks we should be looking to get out and test.
Since there isn't a whole lot left to show in the rebuild thread, I thought it might be fun to play a guessing game.
Let's see who can guess the time slip incremental times.
Pre-rebuild setup:
- 79 Malibu naturally aspirated, small tire/stock suspension car
- 3258 lbs w/driver
- 582 bbc making 1056hp @ 7500, 811 ft/lbs at 6000-6500
- Rossler Terminator 5 1.80 glide
- Ultimate Converter 8", 6600 flash
- 12 bolt with 4.11 gears
- 295/65-15 Hoosier DOT D/R tires
- launch at 3500, shift at 8000, 8200 through the lights
- MSD 7531 typically set with 12 to 15 degrees taken out on the launch for 1.2 to 1.5 second with the launch retard.
typical times were:
1.25 60'
3.51 330'
5.43 @ 128 660'
7.09 1000'
8.51 @ 159 1320'
Average D/A 1500'
OK, new setup:
- Biggest change is weight reduction of 350 lbs, down to 2900 lbs w/driver.
- Also, rear end is now a TRZ Fab 9 with the same 4.11 gear ratio
rear tires will now be 275/60-15 Hoosier DOT's (unless M/T gets off their butt and releases the 3754X here real soon)
- front shocks revalved with the big gun rebound valving. Hoping to get a better control over the front end to take the wheelie bars off.
- If I can control the wheelie better, another goal is to start reducing how much timing is taken out off the line. Would be nice to start getting after it sooner in the run.
- initial runs will be made with the existing converter although discussions with Lenny have estimated the converter will tighten up 300-400 rpm. Will have it re-stalled once we have some data for comparison.
So there you have it.
Let the guesses fly to what the time slips will look like.
