Aircond Compressor Draining Too Much Power?

[RENESIS VIII]

VDO doesnt have that. It's one whole control unit in the TB. You're gonna have to change the TB unit.

See this video below on how canggih VDO TB is.

Mine is MMC not VDO

Maybe I can consider this as next upgrade for my car since this is not very expensive.

to be frank, there is no changes in pick up but your belt life span shorter
had use it before, car feel more better to drive




This one are.. like high cam only.. no d.. worst than high cam...
sometimes if the drop not so high, just mod a toyota FIcd, close case, no need to waste money buy a new TB where brand new also can not use one.. last time I tried a lot of recond TB ended buy new one (that time near RM 1000) the same after fixed when aircond compressor kicks[/QUOTE]

Your explanation saved my money from buying that pulley.

This problem of mine only appears during very hot weather. When air cond compressor is not kicking in, then the idling is ok. On cooler weather, idling is also ok when compressor is kicking in. In fact, I did a test again on how many RPM did the compressor drain off during cooler weather and it is around 500rpm or less unlike hot weather where it takes away 1000rpm. No wonder my whole car feels very under powered during hot weather. If I want to maintain RPM at 1000-1500rpm idling during hot weather, I need to step quite a bit on the throttle to keep the RPM up. Other wise, it will drop to 500rpm or so and the RPM will jump up and down like the video.

If mmc then just install ficd can dy. I got 1 unit with wiring if u want. Hehe

VDO one is it the plastic screw thing that always break, right?

How about do that change gear set inside throttle body?

iirc yes. haha

u remove the gears and coolant hose and plug it or u can leave it there if u want.

You mean to install FICD, these gear set should be removed?

u can leave it or remove it.

Now this explains a lot on why my car felt quite empty without the pulling feel from torque when the air cond compressor is kicking in during hot weather. When the compressor is not kicking in or on cooler weather, I can start to feel the torque pull around 2000 rpm. This dyno is done on your car?

Your 3SZ-VE engine?

Wah! lost 10bhp.......fuh!

No wonder the car felt lethargic when air cond compressor kicks in.

That is why need to off air con when need power or rev high........lol

Or mod to compensate power loss and get back stock performance.

That is silly, right? Pay to get 10bhp to lose it on the air con......lol
