Hi All,

I am curious if anyone is working on a weight loss plan for their 2007 GT500? I have a few of the obvious mods either done or planned but did not see a thread on this when I did a search.

I already did the damper and a one piece aluminum driveshaft is on order; the Steeda torque arms, Bassani headers & pipes and the CAI kit all made minimal reductions.....all in looks like only a total of about 90 lounds less and that is making the assumption the TVS weighs the same as the Eaton.

Are there any other light weight parts available that anyone is aware of? If my math is right I will be at about 660-675 RWHP when I finish up the TVS and really do not want to add the shortblock stress of building more engine than that...the next obvious step to me was to look at a diet.

Any ideas guys?

Overall goal is to have stock appearance and lots of umph....doesn't help my cause when the driver is 6'3" 260 either.....

Thanks,

Rob

Rob,

TVS really isn't anymore heavier than stock. Didn't weight them, but my arms felt the same. You can lose 10lbs by taking the rear axle weights off. The replacement front k-member is suppose to be alot lighter, but stronger. Won't know about rotors until i do mine next week.

Thanks for the feedback,

I would appreciate it if you can give me an update when you get to the rotors; I had read about the k-frame idea but not sure I want to go down that path yet.

Are you happy with the BBK throttle body? I am doing my shopping/research for this right now....not sure on what option I am going with other than I know I have ruled out the Whipple mono blade.

Thanks,

Rob

Tubular K-member and lower trailing arms would make a noticeable difference. And it would help with the car's weight distribution.

Fiberglass hood.

2-piece rotors save weight and decrease rotational inertia.

Battery in the trunk. No overall weight improvement but improved weight distribution.

Race seats: leather/power seats are heavy

Rear seat delete.

Extreme and expensive: alum 5.4

The magazines have had good results with the BBK and there is also the VMP throttlebody too.

Lighter weight wheels improve performance beyond their simple total weight loss by virtual of lower rotational mass. Having said that I just put on a set of (not light) 19 inch Saleen Heritage wheels. Oh well. They look bitchin'.

i'll be posting once done with install. BBK has been just fine, except once it stuck at wot..i just reset the spring tension, adj the voltage a bit, and its been good. But haven't dyno'd again yet. That will really tell. VMP has a 66mm.

I think once would be enough for me to classify the part "not good."

Aluminum (aka Ford GT) block - 100 lbs (JDM offers wet sump version)

Carbon fiber fenders, doors, hood - ?? (saibon/roush)

Griggs suspension and brake system - approx 300 lbs

The above would probably take off about 500 lbs total.

The cost is greater than $10,000, and probably would be closer to $20,000.

The average 'glass hood weighs 4-6 pounds more than the stocker. An outstanding, hand-laid one will weigh 8 pounds more than stock (right ProGlass kids?!)
Oh...and worth every freakin' ounce. I'll make more horsepower in a heartbeat....get rid of my ProGlass hood? Never!!!!!!

You could also try an SLA battery like Dyna-Batt or Odessy. They weigh 14.5 lbs compared to the 40+lbs of a regular wet battery.

The Odessy battery for our application according to them is 38lbs.
That Dyan-batt looks interesting though.

People serious about weight reduction may be prepared to deal with some tradeoffs. While that battery is meant for everyday use. There are people that use ones built for race applications in their cars for several years with no issues.

This battery may provide decent life and cranking provided that it is kept away from the heat and the car is driven at least once a week so it keeps the battery charged. I would also think that you would not want to be running your car radio with the ignition off for long.

Here is a good writeup someone did on these batteries some time ago.

Just curious if you did the rotors yet and have any feedback on them. I am waiting for all my care packages to arrive and should be started within the next few weeks on the rest of the mods.
