Temperature egt

[panterargento]

Hi to all, I would like to understand how should touch the maximum temperature egt to stay in reliability, referring to a new bravo 150hp mapped and defappata?
Thanks in advance.

Watch...it depends on so many factors...the exhaust ******?with kat?the prekat ? this?you only have the map? the egt probe dov'? was the mass?

[panterargento]

Hello, the precat ? the original, the dpf ? been replaced with a straight tube with preparation of the pressure sensors and lambda, the rest of the exhaust ? ori.
You ? this map, which injected about 80mm3.

[mariodarkblue]

Uhm, you basically discharge ori, only without the dpf...well, considering that you have the prekat under the turbo, I would stay with egt 700? max, given that the prekat does not dispose of the heat to the turbine as it should...(consider that on 147jtd I did - turbine, filter, asp, skat, intercooler, 5 - very high rpm over 230kmh arrival at 1,050 degrees)...

[panterargento]

I understand...the last log I did with multiecuscan in 5th gear at 4000rpm in the small incline 2%/3% the temperature precat was to 645 degrees, I assume that in 6a should I be more? high...the fact ? I wanted to remove, but I lost quite a bit below 2000 rpm when I had the 159 150 hp, it seems that the ori give a little more? readiness to change.

Under 2000 you do not lose if you correct from the map, what you need to do is first load the turbine..;)

In my opinion, 1050 degrees are MANY, I have the probe on a pipe of the hills and not on the 4-1 (changes of up to 50 degrees in comparison to the 4-1 and me ? also been confirmed by a person who has both a probe on the 4-1 that a probe on each tube collectors to 5cm from the top). I have reached the maximum 910 degrees to 250 with the map I rolled 267 hp. Then will be the collectors big that I, sar? the turbine vent is good, but is the machine I cannot get it to heat up. Even with advances stock, and over 110mm3 has done more? of 900 degrees. Pressure turbo 2.3 peak 2 to the limiter.

Hello I would not go out of topic but can you please tell me s? and best to mount before or after the turbo?
just for curiosity?..
thanks and sorry for the intrusion...

To be placed before the turbo

Ok thanks jack, the next operation will be? one of the downpipe to keep the temperatures more? low.

[panterargento]

Guys sorry, but advances tend to raise the temperature?
Or ? to the contrary?

[munro]

usually the egt with a p? most of the advance tend to fall....even if just a little....

I would add to monitor the temperature of the air at the outlet from the turbo...
through its sensor obvious...
if ? far superior to the 60? C and the case of mounting an IC worthy to be called so...

Advances decrease in egt but raise the pressure in the combustion chamber. That's why? not good to overdo it. Then come to a certain limit, no improvement. Let's say that at high rpm, you should have the injection the pi? close as possible to the pms. Abroad to usa to have the injection at tdc from 3500 rpm and up, with high iq for? means advances are very high. This ? valid for? with an AFR of 16 or more, with AFR lower the combustion takes place pi? quickly and you can? to anticipate a little less. Let's say that you should stay within 5 degrees after tdc. I personally high on my I'm at 2.5 degrees after tdc.

Quoto full!..
s? one is able to keep it under 20? pulls out a nice little pony and reliability?..

Riesumo this discussion not to open another, in practice ? time to replace the precat with a downpipe, I would like to know if the bag to hold more? the low temperatures of the turbine, is also to lower those of the exhaust manifold, as I you ? broken a prisoner as a result of the high temperatures with the consequent vent.

But tisi and broken while allentavi or stringevi or alone?
however, should never be too narrow to allow for elasticity? in the heating and cooling..

[panterargento]

As she felt the vent, as the first solution I shook a little all the prisoners, but one you ? broken, but still showed gi? a bit of soot near, so I assume that it was already? cracked, even why? once I touched you ? broken.
But the thing that I want ? to know if the downpipe is also to lower a bit the temperature of the collector.

[QUOTE=jacktheripper2;68830]Under the 2000 you do not lose if you correct from the map, what you need to do is first load the turbine..;)

Therefore, it will have to? act only on the increments of the turbo, or on the VGT, or both?

Sorry for the double post...

[munro]

if you are not from the diesel in the bottom you can keep the vgt closed as much as you want and the turbo pressure in the map even at 3 bars but not succeeding? nothing of all this...
the turbo it to make it turn in the exhaust gas,the exhaust gas in the combustion chamber, the combustion chamber if you do not introduce more diesel fuel where and when you need it....you do not have the above....
the trick st? in touching the maps lambda "gaining weight " a b?l p? where more do you need....
but not ? the only thing that should touch me...
you should first of all adegure your request by dw from them and then adjust the various tl granting the lambda...
only downside stress to the clutch.......

[panterargento]

OK all clear munro, but sorry if I'm repetitive, this downpipe lowers the temp of the manifold?

[munro]

the temperatures with the downpipe down just a little but lower....
what is lowered, and also a nice p? I would say..
are the pressures that give great benefit to the turbine valve springs and exhaust...
on the other you "empty" a p? the engine sottocoppia when the prekat is eliminated...
? the classic case of "covered short"...
fortunately you can? find a remedy...

[panterargento]

Instead of mounting a stainless steel manifold, what would change in terms of temperature and performance?

[Exelion1986]

The change better in terms of price/performance ratio ? the downpipe. Change the manifolds becomes gi? pi? expensive, even considering the fact that normally it is set to the turbine. Doing only the manifolds, I don't think that it changes the temperature, however, does not depend on the material. With steel you have more? strength and less weight, if they are done well (the cio? lengths and fittings right) then you have secure less interference problems to the discharge and, consequently, pi? performance, but according to me for processing road the game is not worth the candle. Rather if you want to go over why? contacts a good turbista to make you change your original?
