DPJ's GTRS Eliminator Install and Development

[m0rk]

now might be the time to start looking at EGT's

 

[The MoffMeister]

EGT's??? what are they sorry to ask lol

 

[m0rk]

Exhaust Gas Temperature

How hot the air is exiting the turbo

 

[The MoffMeister]

and how do these affect the cars power etc or do they??

 

[m0rk]

Hot EGT will mean a hot turbo.

Which means too much is melting bearings, damaging fins

So I suppose that 'hot' EGT's will indirectly mean a loss of power.

 

[The MoffMeister]

ah i see now so keeping them at good temperature whilst getting the most out of the turbo is crucial then??

to hot no good

nice and warm very toastie lol

 

[m0rk]

I beleive more timing & WI will bring EGT's down (as will over fuelling, using petrol as coolant)

 

[The MoffMeister]

then low mpg etc etc

 

[m0rk]

no, bore wash.

You've already got bad mpg if you're running WOT & high revs in a BT car

 

[The MoffMeister]

god im lost already lol

I'm kicking myself for not getting a boss on my DP when I had it made - I'll have to look back and find the relationship between cat temp (that I can measure) and EGT.... ...and look to getting an EGT sensor sorted....

I believe more timing & WI will bring EGT's down (as will over fuelling, using petrol as coolant)

I hope so. I also think that getting rid of the big boost surge has got to have helped on that front.

Yep 1.6 litres a minute. 4m/litre average consumption.

 

[The MoffMeister]

Wot??

 

[m0rk]

Wide Open Throttle

 

[The MoffMeister]

ok sorry but asking helps me to understand to lol

mind you what dave has learned is amazing

 

[m0rk]

Some say he has a sponge of a brain like a new born baby, others claim that the knowledge was leeched into his mind from the front bumper he used to run

All we know, is he's call DPJ

 

[The MoffMeister]

personnaly im fed up of him taking all the credit for this, i get constant pm's and emails from dpj asking how to do this and that and explain this and that wish it would stop

 

[DPJ]

Some say he has the brain the size of a planet - most say you can't get planets the size of peas....................

good advise from m0rk re egt's if now looking at timing...
I cant remember if your running your water/meth on these logs or not.. for its contribution to afr or not.. ign timing, and or pull, will be balance of CF,EGT and lambda (but you know all that already)

some great prpogress Dave.
well done

 

[Jon@VAGWORX]

Yeah, sounds like your getting there.

Personally i'd fit an egt into the manifold, as i wouldn't care what the temps are post turbo, its cylinder temps that i want to know.

 

[ibizacupra]

I fear for pre-turbine personally, although its the best place technically to install one... loose the thermocouple and its clips your turbine on the way out.

mines on turbine outlet 50mm from turbine itself.. worked well for me there.
