Can try install air scope at the boot :) hahah (Joking)

ANyway, check your boot. My rear have air holes.. To flow out the hot air in the boot area (Old car Nissan Sunny). [/b][/quote]

true true.... but where to get it??? :blink:

b11boy,
easy to get only.. Our Stock one very week nia. Get from halfcut also can. Get new one also less than RM 150 nia. (For my case lah)

YOu can ask your wireman to wire when you transplant. Shoul dbe no extra charge kua.

IF you see at the tail light. Beside the Signal lamp you will see some air holes... Like shark :) It actually goes inside with a J curved pipe. Air can go out.. and water cannot come in :)

The longer the battery wires(resistance) are from the alternator/regulator, the higher the losses are - Ohms' law.
Look at the location of your existing battery and look for air pathways that it gets. It may not be necessary to relocate it for cooling purpose.
My 2 cents.

thanks for the advice...
didn't occur in my mind that it will increase resistance
i have chose to use thicker cables and a plastic tube type to protect the cable
i have no choice coz my aif filter was blocking the way.... *&^*^(&@(&@ the person who did my aif filter piping used the battery place oledi...

but accoding to my mech.. it is better to put it to rear coz engine bay got more place. the bad thing is that i can see the rear lose some place and not so nice anymore :)

If you are a very very sensitive Drifter, precision driving fella. YOu will feel the weight difference.

dudes,

i've already relocated the batt (regular acid) to behind my passenger seat for almost.. a year now. things to look out for is the acidic water that evaporates out. Do clean it often, with a wet cloth.

People in the racing/mod industry would prefer to use WELDING cables, Amp ratings from 150Amp to 300Amp. Orange color, about RM2 per feet. For lugs use pure copper or the copper and zinc plated one. about RM1 per pc.
Where to get? from your hardware store(s) opposite State Police Headquarters.

btw,
in racing, such as Japan GT, almost all the cars have air scoops at the rear for cooling stuff like the rear differential oil coolers, pump and scavenger cooling.. etc etc...

cheers,
Stanley/ninja

when u say this.... it reminds me of my fren who has relocated his battery to the rear... he is using orange color cable which i think it ugly :lol: ..i dun know it is far much better than the black cable... :lol:

i chose black color cable over the orange and red because i know it will not get dirty easily and not so obvious

 

[johnsonlam]

Well. the colour of the cable is not any issue because it will be concealed under carpet anyway. But the Thickness and the Ampere that it can withstand is really important.

You don't want it to melt and burn.. It will cost you YOUR CAR !...

Remember to buy Fire Extinguisher too.. RM 38 only..

actually i am not sure wat is the amp and the wattage coz the wireman did for me... what i can see is that it is really thick.... thicker than my original battert cable which is quite worn after so many years of usage

where to get the $38 fire extingusher?

 

[johnsonlam]

RM 38 Fire Extinguisher.. @ Brothers..
The last time I saw.. RM 33 only..

Got in Metalic Blue, Red and Silver can..
Size of Insecticide Spray Can.
