Engine part question

[hyperkinesis]

the parts in red part @ is a hot air exit, I need to know the function of the part 1, I'm in a very hot climate and temp on the car runs on the middle of the temp gauge.. If I eliminate this parts take any bad effects or is not recommended eliminate that?

The right piece blocks air and forces across cylinders, so no it can't be removed without putting something else there. Sure race setups don't use heat so there must be something to replace it with.

little or no effect on engine cooling, #1 air from the engine fan comes up into the blower and out #2 to the shrouds around the exhaust headers into the mixing valves into the car. eliminating this/these pats are also called backdating where air from the engine fan goes directly to #2 bypassing the blower fan. cleans up the engine compartment a bit. Middle temp gauge good. Car looks like a carrera (no make/model/year description ) but you should have a carrera oil cooler in the right front wheel well with a fan

but I can turn of the fan on par #1 and pues an plug and remove the part #2? because because hot air is always coming out of there
but what is the function of this part #1 on the picture??

search "heater backdate" and you will get all the info you need

yes you can remove these parts easily but you will need to order backdate parts or blockoff plate

[James Brown]

part one is the intake air it is under a little pressure from the engine fan but porsche wanted a little more in the cabin to quiet those pesky owners that want a clean windshield in the winter. So they added a blower to boost the air pressure output. Started with the SC model. You can "bypass" the engine blower yes but air needs to be circulated around the headers weather or not it is going in the cockpit or not, adjusted with the air levers down by the parking brake.

What year is your Carrera?

You want to be focusing on cooling the oil to bring temps down in a hot climate.

yesr 1984 and yes I need more cooling oil but I already add a fan to the oil cooler the temp gauge in a regular day around 85F degrees is about 1 or 2mm above the midle line.. in a day

I would leave both pieces in, and on hot days gradually pull up on the red handles (Be sure that you do not have autoheat!) until the fan starts to blow, but the heater boxes have not diverted hot air into the cabin.

Why do this? To clear hot air out of the heat exchangers and blow it out under the car. You'll notice a 10-15 degree drop in oil temperature on a hot day.
