Proton 4G13/4G15....Satria/Wira/Saga

[damone]

I have already changed to a lightened crank pulley. I suspect it is internals, as the engine revs like it is on highcams when the AC compressor kicks in.

then u can try decarbonizing the intake manifold and install a FICD thingy to stabilize ur idling when u turn on the aircon

 

[sumimasen]

damone,
there is a probability that u nid to service up ur throttle body, since u edi mentioned that u r running SVDO type which prone to hv dis kind of disease.

 

[damone]

Throttle body and intake have been cleaned with threebond cleaner just one month ago. No difference in between that. The main problem is that when the AC kicks in, the the car will idle like it is on highcams. When the compressor is not working, the vacuum is steady. It got worse after I install the LCP.

you might need to check on your AC compressor
from my experience might be ur mechanic put too much of AC gas in it.
coz i face such experience before...let a noob mechanic add AC gas then problem occur then i sent back to my favourite workshop and my mechanic just release some AC gas then problem solved already

 

[damone]

Thats a really good idea. I will check it out tomoro and let you know the outcome.

Damone - just a question of curiousity. This LCP is very much undersized or just marginally (like Mythelogy which is claimed to be 5% smaller only)? I wonder if super undersized pulleys will mess with the whole system?

Also, if your car is Siemens, you might want to go to a Proton SC and have them use the PDT2000 or whatever they call their diagnostic system and have them reset the errors if any.

 

[damone]

Apparently there is nothing wrong with the compressor, but am willing to go find a second option.

My pulley is actually the same size as OEM. Regarding the PDT issue, well, it is worth a shot. Any proton SC to recommend ard subang or sunway?

i wanna upgrade my satria 4g13 soon.. i aready changed a bit stufz on my 4g13 currently , such like 4-2-1 straight pipe wif a trumpet , HWL adjustable , K&N Open Pod , NGK iridium , 8.5++MM plug cable ( i 4get dy =) ) BR clutch set wif lighten flywheel is my next mod .. After that , i will buy pipercam , adj cam pulley , mivec injector , and 1 SAFC . Um.. can i noe if this is a good way for mode my 4g13 ? good or bad ? I will consider transplant in the future but not nw cuz i m still a students wif age 19.. Will the horsepower increase abit ? and the engine will have a good responses ? How about the FC , will be high or still ok ? what thing i still need to do.. ? 1.5 block and 1.6 strocker will be list in my tiny 4g13 soup up project also , but not nw... =D ... any 1 give suggestion ??

drexchan,
understand a friend of yours have install a Twin TB, understand in term of performance it gain what is the range of power gain in TTB and for us in real world how is the FC look like?

thanks

He's got torque at all ranges and FC has never been a concern when installed the setup. Damn interesting. But he's said TTB is only useful if you have internals all done up otherwise gain will be minimal.

That friend of mine is our mr. khguan lah... ask him directly.

Anyway, what izso mentioned above is true.

Noted, that mean when use 4 TB is even better, i agree torque at all range but we use our car for every day use FC still main issue. we cant attack corner or drive like a sprint race all the time right.

Around 70-8x HP on wheels possible if tuned properly

 

[khguan]

i read from some articles... a properly tuned TTB setup can get 80% of a 4-throttle system.

For my car, the throttle response n torque gain are great. The throttle response is like more than 100% increased after tuning. No joke. Havent send for dyno yet.

izso,
On a stock car the gain is there la.. will be noticeable.. not as minimal as u mentioned la..

Throttle response will be much better for sure... it will be something like installing a weber on an EFI car... minus the increased FC.

The TTB setup is ideal for engines with internals done up like head jobs + increased displacement, as the intake system became the main restriction in the entire combustion system after all those internal mods.

 

[meltan7]

what is needed for this TTB mod? cost of mod?

Chewww.. I only quote you nia. Not I say one, is what I understand from what you say! Anyway, that's also the reason why we pnp the manifold and TB what. But TTB would eliminate the need for the TB pnp I guess.

What is needed for TTB? Two throttle bodies and two manifolds and a helluva lot of custom work! Only khguan has done this so only he'd know the actual cost. Wait for the taikor of DIY to reply la.

TTB setup....interesting
Dunno wanna do for my 4G92P or not....hmmm....

khguan, dyno already let us see the graph. Thanks ;)
