back from the dead

 

So @ 265lbs I am a severe disadvantage at the drag strip....I should be given a handicap.....or buy an suv and forget about it??

 

Anyone having any problems with the Hawker Lightweight battery?

 

nope, runs 14.1 volts with my hypervoltage kit. Need to make a custom holder bracket

 

Only problem is when I have to have my truck pull it to start when I forget to start the Z for a week

 

lol I'll keep that in mind - just installed mine last month

 

there is a car version that weighs like 2lbs more. Sheesh just buy that lol.

 

?

 

I haven't had any problems with the Hawker Odyssey. I do keep it charged on a Battery Tender if I don't plan to drive it for more than a week. Just don't run any accessories without your engine on. PC680 w/jacket - 16lbs.

To secure the battery down, I use a dry piece of wood and some old denim to block the space between the tiedown bracket and top of battery. It's guetto, and I've been meaning to fabricate some aluminum brackets someday...but then, procrastination set in, and this setup has become permanent. I'm glad there's a cover!

 

the 545 is for motorcycles it weighs like 14lbs the 680 is for cars it weighs 16lbs

 

Thanks for clarifying, that is what I have the 680

 

And your car still dies after not starting it for a week? DANG maybe i wont get one of these.....nah yes i will

 

I wouldn’t call the disadvantage “severe,” but at 140 pounds, I might be able to shave 0.05 seconds off of your time driving your car.

 

125 lbs lost would feel like 11 or so whp which is like .12 sec faster in the 1/4 mile

 

that's the "raw" benefit you get in straight line acceleration...

weight loss as way more benefits in other fields as... braking and cornering for example.

a good diet is critical if you drive the car as it should be driven. And you will feel an HELL of a difference with -150lbs. The car is completely different on the track with and without the instructor for example.

There is also a fuel/brake efficiency issue. Think of the extra fuel and extra brakes it takes to accelerate/brake 100lbs of stuff constantly.

I've been runnin the 680 hawker for more than 1 year, and i has never died. Even sitting for more than a week.

 

So withe the Hawker battery and no spare/tools in the back how does the Z perform?

 

faster than 2006 corvette Z06!!!!


no seriously it's not a massive change. You can feel a slight difference. I feel like the car is raised up higher slightly

 

You need to corner balance it first then test

 

I just made a purchase that will lighten up the front end a bit more. I will post pics when they come in next week

 

my car weighs 3140 with me in it, 3000 with me out! i took out stereo system, cats, spare tire/tools, leather airbad seats. Thats all i can remember right now.
