Engine/Transmission (1998.5 - 2002) High EGT's

[fullthrottlefarmer]

High Egts what is the best way to lower these?See sig for power upgrades. I can hit 1600 in a flash. Power max 3 is almost useless it gets hot so fast.

the only thing left is a bigger turbo:{

I have a HX-50 and a HX-40 and I still can bury the 1600 degree gauge. I ran all summer at the track all day long several times a month. I am cutting the life of my motor I am sure and a lot of others on this web site do to that dont have twin turbo's. I make 14 second passes over a hundred of them and no problems yet. I will get twins soon to lower my EGT's. I wouldnt be that concerned just dont tow at or maintain 1600 degrees for too long.

TST says very certainly that a pyro is recommended with the PMAX 3, even with STOCK INJECTORS!!! So you add stage 2 injectors, and then wonder why you have high egt?



The PMAX is FAR from useless, but you have to let is be part of a well-designed SYSTEM. Obviously, you have the fuel to make some power, now you have to bite the bullet and get some air.



By the way, fuel is cheap, air is EXPENSIVE.



First thing is to lose the stock intake. Go with a Scotty 2 from Wildcat.



Then you will need to open up the exhaust. At the fueling level you have (about the 400hp mark), you will need a full 4" system. Pick one.



The bulk of the solution you need is a new turbo. You are simply exceeded the ability of the stock turbo. The most cost-effective turbo for your situation would be the Dodgezilla 35/40 hybrid. It's a bargain at ~$650.



After that you have the PDR 40, which can handle up to 450hp or so.



After that, you have the B1 turbos-- the most expensive, but the toughest and probably "best" single turbo available for the CTD.



After that, you should be considering twin, compound turbos.



Don't take this the wrong way, but I would recommend that you do more investigation before you do more upgrades to your truck. A little reading here and/or calling the manufacturers of the products you bought would have kept the high EGT from being a surprise-- you would have known to expect it.



For now, just keep the box below setting 3 (I know it's tempting) and your EGT problems should be controlled until you can get more air for your truck!



It's good to see another North Dakotan on here. I grew up in Beulah and Bismarck. I have been to Devil's lake a lot-- great perch and walleye fishing!

Hohn. Thanks for info. I do have a pyro gage. I have a BHAF filter for more air. Maybe not as much air as a scotty but more air. I already have a 4inch exhaust. I understand a turbo is next just looking for advice on which one to go with. I realized my egts would climb. I did not realize how fast they would climb. I have done alot of reading also. Sorry I must of came off as being naive to this whole subject. I also did not mean to intend the pm3 is useless I just cant use it at high levels right now.



So any way where are you located at now?

At the power level you are at, a turbo is definitely in your future. Just remember that since you already have the power, changing to a different, bigger turbo will yield more lag than you have now. Takes from the bottom to give to the top.



A cam could also help you out, and doesn't take from one area to give to another - but your turbo is still too small for what you have.

I live in Cheyenne now and love it, but I miss ND.



Listen to Keith ^^^. He's the man. I am sorry I didn't see your sig and all the stuff you have added.



There are a lot of highly regarded turbos. I think you will find the HX40 variants to be the most popular amoung TDR guys. Whether from Diesel Dynamics (Keith Lockliear who posted above), Kurt Yardley (AKA KwikKurt), or Piers Diesel, they all have their pros and cons.



Generally, a stock HX40 is not much to write home about, but the tweaked versions from the vendors listed above are a great turbo.



Also, most HX40s are best when 38psi is not exceeded. They have a bad habit of coming apart when abused (45psi, nitrous, etc. ).



While it's considerably more expensive, the B1 is an almost indestructible turbo, and can make cool boost to much higher levels. A B1 can easily pass 45 psi, and you will see the limits of your stock headgasket before you find the limits of the turbo. They are very tough, and can withstand abuse that would melt or explode many other turbos. The only way to go better than a B1 is to go twin turbos.



I think I will wait until I figure out a good way to setup some twins that use the stock HX35 as the secondary. I will probably run a little smaller housing and just use a HUGE external wastegate to relieve the choke and feed the primary turbo.



Right now I am ruminating on the possibility of an HX35/B2 twins setup.
