Engine/Transmission (1998.5 - 2002) Need Experince Lowering EGT'S

[ryecreek]

I need to lower egts i'm having to pull 7k-10k quite often from payson to phoenix. the road is 65 mph (75-80 ) with some 6-7% grades 7-8 miles long but some have sharp turns (back to 60mph or so) which kill me and the egts. i'll hit 1400 with the comp on what ever never above 3 and the comp settings could go on and on



now to it, i'm gonna get somthing i'm thinking of the snow stage 3 don't want to spend more than the cost of it like turbos cam



or even cheaper with a 3pc ex manifold quicker spool would be a kicker



any thoughts on twins adding a hx 35 to the b-1 in some config or changing the housing/s on either the piping isn't too much

not wanting to touch the mtr(cam,frie ringing ect. ) since it's about to round 340,00

This will turn out to be an interesting and informative thread.



For my 02 though, I think there is not a way to lower it as it (the temp) is a direct relationship to the power you are demanding from the engine.



Heat is removed from the engine by 1)Usable work, 2) Coolant, and 3)Exhaust.



What is not extracted as usable work most of the remainder is passed out thru the exhaust. It is pretty much a linear percentage of total power input to the engine.



As I said this is going to be and education, but I think you gotta gear down!

 

[Fishin Guide]

Yes, pulling it down a gear should help a bunch!



What size exhaust housing are you running? How is spool?



You can run your turbo in a twinset. Take your pick of vendors, but the HX35 in a twinset is very common and used in towing sets all the time. Usually, the HX 35 is a hybrid of some sort, but a stocker will work.



I have one of Source Automotives sets. It uses a B2 and works very well. I also have a HX35 hybrid on top. Very quick spool and lost tons of heat on the temp side. I thought my gauge was busted after the first 5X5 WOT run.



Do your research. There's lots of options.

If you are running the stock housing an increase in size to a 14 sq. cm waste gated should help. Probably about $400. The water/meth should help also. Both would be less than gearing but the housing might hurt your spool and the H2O/meth needs refilling. Take your pick!

I'm running the b-1 the hx is a spare

That's just it i have been doing GRABBING 4th and feel like a tard with all the power left

just trying to make it useable!! way to many strokers and maxs on fri (CAMPERS) for me to get passed when in 4th (just sounds bad spun out [2600 65mph])

As for exhaust housing i'll make it a point to see Ken Diaz in the next day or so when i'm in the valley cause i have no idea

spool is alitte slow without comp fueled up to 3 or more (submenu)on any setting (1+5 spools ok)

I've gearin' down don't wan't to that's why i'm asking for all to chime in

WHAT WOULD YOU DO

 

[MarkMiller]

I just began running a snow stage 3. I have not towed with it yet but it seems to take my unloaded numbers down about 200 degrees on the larger hills and I swear it feels like it spools up the turbo quicker when I lean on it. They have an 8 gallon resevoir that is bed mounted or if you do some looking you can use another under body type tank. Mabe even an airtank is what I am thinking. A 3 gallon air tank from air-lift runs about 50 bucks, is aluminum and a remote fill line can be rigged up into the fuel filler hole in bed.



the stage 3 system is noce because it taps both your EGTs and boost. It runs itself off both those to help with egts while towing or when you want to stomp someone it can be switched to read and map only off the boost. You can also adjust the gain of the system on the controller and if you need you can adjust the pump pressure on the pump.



One note on the snow stage three controller, the boost line that is fixed into their controller and you have to hook up to, it is 3/16 poly line instead of the normal 1/8 in nylon line we all use for our boost gauges. the poly line is too soft to put in a normal compression (crush collar type) line fitting so I had to track down a tube insert and 3/16 to 1/8 in union from a local hardware store to make it work. I initially shoved a piece of 1/8 in nylon line into the poly line and wrapped some electrical tape around that to make it seat into the compression fitting. (Hey, it was day of, at the Spring fling Dyno day! Big thanks again to Jetpilot, aka Doug from Performance Diesel Warehouse for the idea!)

Which B-1 turbo are you running? Is it wastegated? The B-1 line is an awsome turbo but if you have one of the small housing models and/or one that is not wastegated then there is where I would work on. A non-wastegated turbo creates a lot more heat and drivepressure than one that can run at an efficient range... . Also the smaller housing B-1's really restrict exhaust building heat and pressure.



If you are running the larger B-1 then a Snow water/meth system should really help you out.

I did not get a chance to see Ken (ken is the guy that makes the b-1)at TAD today but he has always called it the big B-1

so i'm assuming it has a bigger ex housing. it does have a lot of lag unless you put the fuel to it

no it's not wastegated (in my tow situation when i start to heat the egts i'm running 20-25psi would a wastgate truly help??

i mentioned the issue to ken as week 2-3weeks ago he said nothing about the turbo

wanted me to get a bigger pac brake (big bucks) mine is a 3" all they had back then

or get his 3pc. manifold

 

[Fishin Guide]

I would think Jetpilot would have some great info on this one.



You could run a smaller housing with a wastegate. This would help spool with lower fuel, but I am unsure if you would or could experience and surge with a small housing?



Wish I could be of help.

Nothing will lower EGT better for the buck than Metanol injection. Since I have installed the system over three years ago, I never see high temps

How expensive is the system? At what altitude are you towing, and how much weight are you towing?. I spoke with Tony from Snow performance several years back, and the system was still very new, so I decided against it.

I bought the system years ago on E-bay when Matt Snow was just starting. Now he is a big shot! I have a five gallon container in the bed, I donot have the newest controller but have the one that works on two stages of boost low and high. The problem with the old system was on the Highway at constant boost I would use all my liquid in a long trip. Now it last a long time. I am in Illnois and do not tow much but load heavy. You can feel the methanol kick in and EGT's drop. I think it was the best bomb at the time and would never take it off for what it does. They have really upgraded the system alot since I bought mine and I have no idea of price. You have to have a large resovoir otherwise you will empty the small one fast. We do water systems so Iput filters inline and shut off valves.

Rick, thank you,

I have been contemplating one for a while now.

Jetpilot should ring as he did above but cams also make a big difference in how the truck performs and makes a noticeable improvement on EGTs and smoke.

Very ture.



I have nothing but a great experience with my F1 Helix cam. Quicker spool, lower smoke and EGTs dropped a ton.



Also, it got rid of the nose over at 2600 rpm. It made the truck pull cleanly to redline.
