need egts lower help!!!!
 

Ok so here is the deal my 96 has a #6 plate, timing advanced 16.5, 5" straight pipe exhaust, gauges. When im cruising around my egts are a constant 1200 amd if I get on it it goes to like 1800 way too high. Also my boost stock turbo is too high maxes out at like 43lbs and smokes horribly. I wanna get this thing right I want very little smoke, more power, and lower egts...please help I fivure I need to tune my afc alot

Need to turn the star wheel back twards engine ..... and slide that plate back a bit.... I think you have a clogged radiator or cac ...... this will impede air flow through the cac and cause higher egts ...... check ur condenser as well ..... this will halp a binch if all the fins are straight and not clogged up ..... do u have large injectors ?

I have stock injectors and I just flushed the coolong system...I know my afc is off and needs to be tuned but im not sure the proper way to get it right

bad gauge. the bottom number is way out of kelter. 1800 WOT with a stock turbo and say 5x14's is believable, hard to fathom though with stockers. a #6 is a great plate, you dont have the fuel to get you that hot. gauge gauge gauge!

Their is no way your hitting 1800* you would have blown something and your truck would be over heating.. 4x4manonbroke needs to learn how to spell lol kinda hard understanding what your are saying. But if your intercooler is clogged it can lean to hotter EGTS but it will not make your truck run 1200 degrees constant. What kind of gauge do you have and where is it placed?

I have a brand new autometer gauge and the prob is pre turbo. I blow way too much smoke it feels like a dog also. I know the afc hasnt been tuned after the fuel plate install.

And let me rephrase it constantly sits between 800-1000 but just barely hitting the pedal it climbs fast over 1200 and if im wot its like 1800

list of whats done to the truck and what has been done recently. some back ground on the problem ect ect. loosen the star wheel. move the wheel to the fire wall side of the afc and see if things clear up a bit. this wont effect temps much but will clear up a bit of off idle smoke. if thats didnt do much move the AFC housing all the way back to the firewall. running like a dog??? @43 lbs through the little turbo? it wont have any top end but should pull very well through mid range. possible timing issue?

ok got timing at 16.5, 5' straight pipe, aftermarket air filter, new overflow valve, #6 fuel plate. now i just messed with the afc tuning it and now something is messed up because i got the smoke down but egts are still kinda high and it has absolutly no power the boost maxes out at 25 psi and shifts through gears quickly and is just a dog. Im so lost and getting fed up. just wanna get it right but it doesnt seem like this truck has a right spot.

bring it to the house. where you located? any white smoke? when did you do timing?

I have a 215 hp engine .. #887 pump.... stock injectors and turbo ... with out fuel plate I can peg my pyro out in a big hurry and not belt out a ton of smoke ....
dosent need to have big injectors in it to have this issue ..... when you load up a cylinder with fuel and you dont have enough Volume of air ( much different than psi ) .. anything over 35 psi is just a bunch of hot air anyways.. and is a waste of energy.

is my spelling better now ?
not on my phone ..LOL
:rocking:

yeah i live in delaware. im almost positive that the truck is being underfueled. tomorrow im going to slid my fuel plate all the way forward and try that

Your not underfueling your over fueling either because your timing is jacked up.. Or your got your injection pump settings all out of wack. All that black smoke is unburnt fuel and unburnt fuel creates alot of heat, and actually properly burned fuel will run cooler than unburnt fuel. Who did your timing and how did they do it? did they use a dial indicator on the fuel injection pump or did they just "wing it" you can try sliding your fuel plate forward and see what happens, but what ever the case its getting to much fuel and not enough air.

So much bad info in this thread it's hard to read :(

It is possible to hit 1800 with a 215 pump and stock injectors. Not recommended. It is also possible to hit 1800 many times with out hurting the motor if you get up there and back right back off. I have hit 2200 many many many times before and not a single problem. Don't recommend that either.

When you add timing it can cause egts to rise higher if you don't have the air to push it.

A properly tuned pump/afc can make or break a truck. You can have all the fuel and air in the world and not ever light the turbo correctly. And make a lot less hp by not having the afc set up correctly.


Back from the forum grave

I know what you mean here ... I have too much fuel and not enough turbo when the plate is pulled ..... nee more Volume of air and not as much pressure as pressure dosent mean much ( hence the over 35 psi your pushing heat and not cool air ) wich can cause lower than expected power.

getting kinda off point but hot air is still air. 55psi on the same truck will unarguably make more power than 35psi. in the EXACT SAME SET-UP. its not efficient but its still slamming what it can into the engine.

and of course you can see 1800* on stock stuff. but to see such numbers you are beating the HELL out of it in extreme situations.

they way the original concern was worded 1200* cruising on near stock stuff with 1800* with pedal down passing (not racing or pulling). this is way out of wack, by several hundred degrees. i still SERIOUSLY doubt this gauge. do you have a buddy you can borrow a gauge from?

as mentioned above a properly tuned AFC will make the truck run so much better but -in my opinion- will not cause these heat #'s on such a low HP truck unless you climbing Everest with the world behind you to the floor. :c:

Can I say something here boys? Black smoke especially on the topend is unburnt fuel so unburnt fuel, high egt's and since the timing is bumped should lower your EGT's not make em rise so I'm gonna go out on a very short limb here n say get the WHOLE intake system from the airfilter to the intake horn pressure tested, I'm will to bet there's a leak somewhere. Cuz my 93 1st gen with a 180 horse p-pump, 35 psi fuel pressure, no plate, maxed n modded AFC, HX35 n exhaust n intake would hit 35 psi boost with the tiny 1st gen ic and I never saw 1400 on the pyro, my dads 96 5 speed with a worked pump, intake exhaust, afc mods, fuel plate can't get over 1400, now my 94 175 horse ppump with a 100 plate, plugged wg, afc modded slid n tuned with intake n exhaust I have NEVER seen 1200 even on a loooong climb in the floor and 40 lds boost.

Check over your air system, get a spray bottle with soaky water with it idlding n spray your whole intercooler, all the tube connectors, turbo and intake horn n intake plate, if you see a leak you theres your problem, also a very badly plugged air filter will do it too.
