the good and the bad for PORTING.

[beyond_4896]

wanan know the good n the bad for PORTING our engine head....

plan to do it for next mod..

 

[SkYwAlKeR]

better air/fuel flow... engine revs smoothly... fc drops smoothly as well...

 

[beyond_4896]

if i after porting, need to tuning again ? If got a tune able piggypack.
-----

Some more, increase flow got same stress to piston if compare with increase boost.

 

[Fluffy]

nope.dont need to re-tune.

porting will give smoother flow..not really an increase in flow..just smoother flow. so dont need to worry about ur pistons.

 

[spyderslr]

porting will increase air-flow while polish smoothens the air flow......its advisable to retune after such mods.....

 

[Fluffy]

what needs to be tuned?explain?:_:

 

[spyderslr]

fuel map, ignition timing n cam timing......

 

[gavan]

if you are using a carburator..then tune the AFR =)

 

[Fluffy]

ahh..okay okay..thanx for the info.:)

 

[beyond_4896]

m using kelisa ejde_t

 

[SkYwAlKeR]

port and polish can DIY??.... hehe.... no money send to workshop la...

 

[d3s]

if u got the tools n the skill then shouldn't b any problem!!!
lot damm lot of work...

 

[gavan]

ohh...kelisa.... =) EFi lo..let the ECU tune by itself lo.. =)

 

[Fluffy]

let the ECu tune by itself?

after the PnP the ori ECu can be tuned to match the mod rite?

 

[mohammadikrami]

How much does it cost....??

 

[Fluffy]

wat porting or retuning?:_:

 

[normality78]

erm.. i think u guys abit messed up here.

he is asking porting. wat got it to do with smoothnes? if u port but didnt polish it, how come it will be smooth?

porting meaning u r enlarging the stock size. hence its increase flow. with increase flow surely u may wan to increase abit on fuel to match.

EFI meaning electronic fuel injection. what got it to do with self tuning?

 

[beyond_4896]

cuz kelisa will tuned it himself. hahahahaha.
wahahaha funny wat.

 

[Dino@Casper]

Tuning itself means that the ECU learns that there is a change in the air intake system and learn to compensate the fuel itself

cuz kelisa will tuned it himself. hahahahaha.
wahahaha funny wat.

i think its REFUSED to be cheat. whahahah
