Quick weight reduction for drag racing...


Five Oh B

Recommended Posts

Went to the strip with the supercharger a few weeks ago for the first time, ran a best of 12.57 @ 110+ mph in the 1/4 mile with a full interior and full tank of gas (removed the jack and spare, though). Ran the car with 17" Bullitt wheels and drag radials instead of my heavier 18" fanblades. Car weighed 3,700 lbs with me in it, according to our local truck scales.

 

Tomorrow will be my second day racing with the supercharger, so to I figured I could get rid of some more unnecessary weight to see how much difference it'll make at the track. In addition to switching wheels/tires and removing jack/spare, today I also removed the passenger (power/heated) seat, rear seat back/bottom, and will run just 1/4 tank of gas. This should be an additional 135 lbs gone from the car, bringing the race weight down to about 3,565 lbs with me in it.

 

It's amazing how easily the seats come out (4 bolts, and one wire connector for the heat & power motor)....

Last time at the track, I had a lot of hood flutter, so I just installed Shelby billitt hood pins....

Weather is supposed to be dry, cool, and overcast. Temps in the mid 50's. Hoping to run 12.40's at 111 mph in the 1/4 mile. Would really love to run below 8 seconds at 87 + mph in the 1/8 mile in the process.

Good luck Brian, I hope you reach your goal :banvictory:

 

Thank you kindly. I had hoped to have raced quite a few events this season, but so much prevented any racing until just recently. Next season we'll really see my GT getting faster and faster (gotta keep up with the Rufstang).

Hi, Page. That is so cool that CF stuff exists for the S197's; I had no idea! A little out of my budget right now, hence the free weight reduction plan I did for this week's racing, but thanks for the info as it's definitely something to add to the long term wish list.

Spent 8 hours at the drag strip yesterday. It's the last weekend of the season at our local track, so it was packed with hundreds and hundreds of racers! Only got in 2 runs the entire day, but both were my best ever runs and exceeded my goals for the day!

 

1st run was better based on mph, while the 2nd run was better based on ET's. Spun a bit in 1st gear on the 1st run, so I lowered the drag radials to just 18 psi for the 2nd run (dead hooked with a 1.80 60' time).

 

1st run 12.345 @ 111.93 mph, 2nd run 12.338 @ 110.59 mph. Both runs were below 8 seconds (finally) in the 1/8 mile, and I even ran 90+ mph in the 1/8 mile on the 1st run!

 

Here's the timeslips (I'm in the right lane, car #4164)...

Congratulations Brian :happy feet: It's a shame you could not get more runs in but you confirmed that your efforts have really helped.

Thanks, David. More runs would have been nice. I wanted to add more timing to my tune as the current tune is so very conservative. I brought my handheld tuner with me, but alas, not enough runs to experiment. Oh well, there's always next season.

 

There wasn't a single new Shelby at the track, but there was a Ferrari F430, Corvette ZHZ (08 Hertz rental car), lots of Mustangs, and even some new Dodge Challengers! A lightly modded '08 Challenger SRT-8 was racing. He was only trapping 107 mph with his 425hp beast. I wish I would have seen the Ferrari F430 run to see what it was pulling - likely much faster than my car.

 

Can't wait for February for the track to open again!

Thanks for the props, Brian!

 

Congrats on those great runs! You're serious!

 

You're now in Shelby 500 ET territory!

 

Rock on! :happy feet:

I'm following in your footsteps, Ruf, so I give credit where credit is due (and you inspire me!). There's a timeslip list here in the forums (drag racing section). My GT is #13 on the list, amongst some heavy hitters with much more power than my modest GT. Next season should see some 11's out of my car, while still retaining 100% streetability.
