Next mod to fix EGT issues
 

I just ran my 01 in the 200ft mud drags and I lost to a 06 Dmax I ran a 5.7 to his 5.4 the problem is my truck is defueling so hard due to my egt’s should I go with twins or nitrous? I don’t like to loose and the egt issue is getting on my nerves.

Definitely get a bigger turbo in there, such as a s300(Super B). Also, I was having EGT issues alot so I added my stage 3 water methanol injection. It dropped my egts almost 300 degrees. I run on your garden variety washer fluid rated to -20 with methanol in it. You also get an added boost in power, might help you put that Dmax to shame.

First do a boost leak test and see if the intercooler is holding up. Then go buy an ATS manifold and port/polish, and match port it to your turbo. I was having some egt issues as well and this basically cured it. I could not believe it but do a search and you'll find a couple of posts. Or go to the Northwest Bombers Board and they will show you how to do it. Pretty cheap and easy and worth every penny. It's easy to get it in there but more valuable to take it out?! IMHO. [guitar]

No offense, but I believe the previously mentioned post would be a waste of money (with his current mods) and if he's turning 40 #'s of boost, I'm guessin there's no boost leak.

By lookin at heykw's sig., he has lots of fuel and I assume a little HY turbo since it's an 01 auto. I believe a turbo would be in order. I think that would be a more wise investment than an ATS manifold to start out with.

Yup, needs a bigger turbo.

Yes I do have a stock turbo. I have been looking at different twin turbo set up's what is the best and most affordable set up? I talked to and rode with a guy running water meth in his 01 Cummins and I was not all that impressed the truck was almost identical with the exception of his truck was a dually and he also had egt issues. What does a water meth kit const and does it really work? Is it better than twins, what about you guys running nitrous?

I have read that meth is prone to preignition on a diesel and could be more trouble than it is worth...

the pre ignition usually happens in the older 12v's because of their static timing, usually not an issue with the VP variable timing. As long as you set the methanol to inject at the right time, you will get a nice added power boost and a drop in EGT's with no problems.

This should fix my egt issues. http://store.summitracing.com/partde...5&autoview=sku

Yes, that would help you alot!! You do realize that is the upgrade kit for people who already have a s-300 as a single, if you don't already have one add another grand or so!

I just found that out that sucks

$3442 for the full set up. Good price for a full set of twins.

You have got to be kidding me, i've been looking at turbo's for awhile now and was only gonna do a single but with the price of $2,434.50 I mise well step up to twins. Probably need a $1000 or more of stuff to add to that price to be complete, but if not I might take the jump.

$2434.50 is the upgrade kit one turbo only

That'll do alot of explaining. Oh'well[duhhh][duhhh][duhhh]

dont feel bad I thought the same thing

Meth preignition has nothing to do with injection timing. It has to do with cylinder temps and compression ratio. The meth preignition occurs when the meth lights off before there's any fuel even injected.

jh

Ok, Im a little confused then. Doesn't injection timing directly correlate to both cylinder temp and compression ratio. The more the advanced the timing, the higher the cylinder temp and pressure, this would be why water methanol would be better suited to variable timing vice static.

Is anyone running Nitrous?

No laughing gas for me, yet. Not until I oring and stud. Im not even sure if it would be smart for me to run NOS with the Water/Methanol kit, even after studs and oring. Maybe one of the diesel guru's will chime in with some wisdom.

Add $1k of extras, and you have the price for the full kit. Thats one of the better prices on the BD twins I've seen. I almost bought those actually, but apparently, they weren't expensive enough for me.[yuk]

Indeed, injection timing does increase cylinder pressure and temps, but so does intake temps and pressure. If you double the intake temps and pressure, you're gonna have a lot more temperature and pressure after you've compressed it tenfold. You may already have surpassed the flash point of the meth, which will cause it to ignite. Still haven't had the fuel injected yet, but you already have ignition.

Nitrous would help, but not with your currently welded shut wastegate. It would just overspeed your already oversped turbo to the point of explosion. A standard s300g is not gonna keep all of your fuel in normal egts. You are setup just like me, only you have a smaller turbo. You would help out your heat and up your power a bit if you had a functional wastegate. Welding it shut with that small 9cm exhaust housing is a tight choke point for your motor.

Nitrous will most definitely lift your head and blow the headgasket in your situation without some head studs and orings.

You could help out your situation some by buying a used HX 35 with a functional wastegate, but it is not gonna fix the problem.

You really need a HTT 62/71/13-14, some head studs. Or the twins would work nicely with your currently fueling as well.

If you just want to win in the mud drags, air down those tires and lock up both differentials. You probably can't use more that 400 HP in the mud anyway, unless you run some paddle tires!

is it true an intercooler from BD or spearco will lower the e.g.t. by like 150*? I read that in the new diesel power magazine. and was considering one

It is called the mud drags but it is more like a tractor pull type course it is really red clay and yes I did air down my tires

I recall some "dirt" drags in California where Maddog with his 1000HP+ was getting smoked by 700 HP trucks cause he couldn't get the power to the ground.

You say clay, well then you were ok for traction. But seriously you need a turbo! One of those ATS Aurora 3000's might do the trick. 1215 bucks on ATS's website. Probably 1400 with shipping and downpipe. Ohamaram did 648 HP on the dyno with his CR, so it should cool down your 500 HP worth of fuel. If you want to spend the money, twins would give you faster spoolup and more top end lungs egt wise than any large single turbo out there.

I would like to get twins but I am on a tight budget about 3K or so

Can you weld?

yes I have a mig.

I prob could have put this with the question[duhhh] but Rip at www.sourceautomotive.biz could hook you up with the stuff to do twins for around $3k, I'd talk to him.

What set up do I get (what turbos do I use) I am uneducated when it comes to choosing turbo sizes.

Do they sell a kit with the turbos and the pipe work, should I use a hx40 or get a hx35? what will the total cost be do you have this kit on your truck?

Smaller on the top, bigger on the bottom:D

I'm not an expert, but Rip should be able to hook you up with an S400 or HT3B that will work with your stock turbo, and all the piping to connect everything.

Most guys run an s400 underneath either an s300 variant= HTT, II, or any other run of the mill s-300 or stock HX 35, or HX-40.

You need to determine your final HP goals first, then size the turbos. If all you want to run is the fueling mods you have right now, you would be time and money ahead to just buy an HTT 62/71/14 or 13ss. and a down pipe for 1600 bucks.

If you need lots of towing capacity or frequent lower stress towing, then you should spring for the twins.

FYI you can get a standard S400 turbo from Dallas Turbo for 650 bucks. I think Citydiesel has them for about the same price as well.

Member Rodram has a hotpipe= connects top turbo exhaust outlet to bigger bottom turbo exhaust inlet for cheap, look him up and send him a PM, lots cheaper than buying a new hotpipe from RIP. If you use his pipe, your gonna need to pickup an HX 35 somewhere. You can find them in great shape for 300 bucks. Then you might as well buy the rest of the parts from RIP at sourceautomotive.biz since it will take serious downtime to fab up all of the pipes on your own. I think you could do it all for 2500 bucks including buy both turbos. Or you could spend a little more and get an Airflo cheaper super B knock off S300-57mm compressor and bigger wastegate/hotside for 850 bucks to use as your top turbo. If you did that, you would have a bigger set of twins that the BD towing twins and have air for 600 HP. If you go with a stock HX 35, you'll have enough air for 550 HP.

Or you can just run the 62/71/14 like I mentioned earlier and make 521 HP with higher egts but still very useable power!

I don't have them. What happens to my truck will depend on how the next 6 months or so... Kind of at a crossroads:D

Txdiesel007 has a set with a S400 and his stock HX35, and talking to him about them has really impressed me with them. More maintinance, but you give up less. And Rip can hook you up with all the pieces, or a complete kit, or something inbetween.

Like BB said, the 62 would be plenty for your current fuel, but if you can spend the money, I say go big:D

With the fuel I have know what could my truck run in the 1/4 time wise and what would be the HP
