The red wire will be tucked, it's just there to show you the wire path...

With a 2 farad capacitor and a deep cycle battery, There are no issues...

Now I just need to clean and i'm 100%

 

Great, now you've got room under the hood for a 6 pack and a loaf of bread. You'll need that space since you're losing all that trunk.

In all seriousness...what'd you do this for?

 

Very Nice.
I have the same kit, but haven't installed it yet. How did you secure it to the trunk deck? Is it laying on top of the carpet or is the carpet cut around the box? Can I see how you made the positive connection up front.

 

That is a great question. Part of me wants to say it's for weight distribution if you really cared about handling. (even then the gains would be minimal) But then there is a part of me that says if someone is that willing to redistribute the weight in their car for performance gains, why the heavy subs? Balance? I dunno. Seems like a silly idea to me. So do a lot of things though and who am I to judge...it's your car. Maybe just to tidy up the old engine compartment and do something different.

Either way, you did a nice job of it. It doesn't look like a hack job which is a plus.

 

One thing for sure, a lot of dropped current due to length of the cable. To each his own!

 

Looks good. Time to clean up the engine bay.

 

I remember test driving the Pontiac G8, and it had the bat in the back, even on the V6. There was next to no room up front, and the trunk was huge, like 18CF or something like that with the bat still in there. I'll be honest, I didn't like it too much, but it would have made for a great short stop to installing the trunk Sub amp.

The guy mentioned something about weight distribution...but he could have been making that up, and not actually consulted with any design literature...

 

had that been the case it should be on the passenger side, but then again that sub box is there so

 

My reason for doing it is weight reduction and distribution, I'm trying to lighten up my car for autocross. Our cars have a 68/32 weight distribution front to rear.

 

There are plenty of reasons for battery in the trunk but I will summarize by saying.... weight, looks, space, personal pref, & ease.

Also those who say voltage drop are clearly mistaken cause my volt meter reads 13.8 all the time and this isn't something i just did, I actually posted up the whole install couple months back and my system has proven itself to start every time even through the blizzard we had. I have no issues and my rear didn't slide out once driving through that snow...

I still have plenty of trunk space plus i can still drop back seats and have access to that as well...
Again this isn't a Honda, It's on the driver side up front for a reason, so there is no need to offset the driver weight be placing it on the rear passenger side but i have the sub there anyway lol...

Anybody else wanna say something neg that I need to shoot down lol???

 

Looks odd with no battery in the engine bay

 

nice, although the handling gains are probably nonexistent, if you claim to feel a difference its in your head...kind of like saying you just got an intake and your car feels faster, lol

 

Nice work, glad to see you got around to cleaning your air filter too.

 

Nice work kyle.Haven't seen you post here in awhile and thought maybe you got outta the maxima game..lol...pm me your cell # we have to catch up.

 

nice work (:

 

We are not trying to be negative, just inquisitive as to what the positives are.

Its seems like quite a bit of work so if I were to do it, i would want some significant advantage. I dont really agree with your reasons for doing this.

weight - moving a battery does not reduce weight. It does redistribute the 30 lbs (or whatever the battery weighs) to the rear which may help handling a negligible amount, but its also taking weight off the front wheels, which will reduce your traction when accelerating from a stop.

Looks - personally I dont think the engine bay looks better at all. It leaves a big hole on that side which looks quite odd to me. You also see the dirty bottom area of the engine and wires down there. The top of the battery and cables are easy to clean and hides the dirty bottom area of the engine. This is just my opinion, so if you think it looks better, thats great.

Space - Big ? on this one. You will never store anything under your hood, but you will definitely store things in the trunk. So you are creating non-useable storage space under the hood, and reducing useable space in the trunk. Maybe I am missing something here, but doesnt make sense to me.

Personal preference & ease - can you elaborate on this? Why do you prefer it and how does it make anything easier?

Again, I am not trying to knock you or say what you did is crap. It looks like you did a thorough job and the way you put it in the trunks looks pretty good. I am just not seeing the advantages of all that work.

 

nice work man looks good

 

Power=Voltage x Current (P=E x I)

Voltage remains the same, but current has dropped (current is a function of resistance), thereby delivering less power.

It does not mean negative, but just stating the law of physics.

To each his own. As long as you're happy, we are happy!

 

Ok Fine i'll explain again....

ok your first one is weight.... The car is basically 60/40 so taking 30lbs of battery plus adding a heavy sub will redistribute that weight more to a 50/50 right or wrong? and not a full 50/50 but closer to it than 60/40 i'm guessing... Weight over rear axle means better resistance to sliding in snow which i must say it has gotten better....

next is looks.........now you might be used to things always wanting to look pretty yes well this isn't one of those, looks mearly means it looks different..."pop my hood and omg where's the battery" looks different huh....

space.....Not all terms of space equals more, space in this context just means added room..... damn and i'm not even a college graduate....Let me show a pic to better help illustrate and guide you my brother.... also our trunk is big enough and i don't know about yours but mine is almost never in use so i'm not worried about the space the battery takes up in the trunk it's the damn sub that's the problem....



Notice how close the battery is to the intake, notice the BIG space it takes up and not being a genius or anything but i'm guessing if you take that big battery out from blocking that space and you leave all that room for air to circulate, It might be better than having something so big hogging up that space and again it's not about 15 hp gains or colder air cause it's still in a hot engine bay but i'm guessing more room or um space might let there be more air in that area for engine to breathe from...don't believe me, look at the first pic then look at this one i just put, which looks freer?

now for personal pref and ease.....

Personal pref is easy cause I the individual wants it that way...lol

Ease is also easy, let's say your on the highway and your in need of a jump or just any single lane area, isn't is easier for a car to pull up right behind you and give you a jump than having to face both cars to each other...

Another ease is now that there more room over there or um space lol some work will be easier, just look how close i am to that starter and those pretty green and black sensors lol

happy? Need more info please feel free lol...


You got me on this one lol....still though i have no issues...

 

My battery is relocated to the trunk. I ran 2 grounds, 1 to the engine and one to the chassis...

 

Let's not be so sensitive. We're just asking some simple questions as to why. You have clearly stated your reasons...It's okay for us not to agree. It's a forum, for discussion and sharing. We can do that without getting all worked up.

Now, with that said, lets get back on topic. Gas weighs about 6lbs per gallon, please don't show up to the track with a full tank and be sure to pull out the sub before you start your laps. You'll have greater gains by removing any weight you can than by using the sub/battery to redistribute the weight you already have (additional weight with the sub). Pull your spare tire (after you get there), jack and back seat bottom cushion if you want to get crazy. It won't be snowing on track day either so you don't need to worry about that.

I'd love to get out there and do some road course driving. A good beating on the car legally through some twisties is as much fun as one can have with clothes on. Or clothes off if your into that sort of thing...

 

Nice job...now you just have to clean your engine bay

 

Ok....so you meant weight distribution, not reducing weight (because you are actually adding weight with extra wire and the case the battery is in). I agree that it will bring it closer to a 50/50 ratio, but really its a negligible amount. Also, having a 50/50 ratio doesnt make the sliding resistance to snow any better by physics theory, its only the coefficient of friction of the tires that affects that. Plus you are taking weight off of the driving wheels which is not a good thing in the snow.

Point taken. Not a criteria that I really consider when making decisions about my car, but its your car and your decisions are all that matter.

more space vs. added room???? Sounds the same to me.....i think you just contradicted yourself in this statement so its quite obvious you arent a college graduate

But i understand now you are saying that the extra room in the engine bay may lead to better air flow to the intake and the extra space makes it easier to work on certain parts of the engine.....ok.....i'll buy that.

Agreed. Your car, you do what you want.

Valid points.

I never really wasnt happy......but now I understand some of the reasons you thought it was beneficial for you.

I give you props for trying do make your car unique and doing new things.

 

 

Another reason to relcoate the battery - So you can fit a big blower

 

BMW's have their batteries in the rear. So does Rolls Royce (mid-car).

 

Yeah, tidy up on the engine bay! Post another pic after cleaning!

 

Fixed.

 

I'm gonna be doing some wire tucking and cleaning and i will post more after...

 

You would have to move 330+lbs to the rear for it to be close to 50/50. You didn't even make a dent in weight distribution.
