3b egts after turbo? + intercooler pixs!!!

[bj70cruzer]

hi so i have finnaly tuned my landcruiser after installing a front mount intercooler

i have turned the screw 3.5 turns out and turbo runs 20psi (wrx td04l) and i have not yet tested it on a mountain road

but flat road throttle floored on any gear redlined i wont go past 500 degree celcius which is 932 degrees Fahrenheit

does this seem okay considering max safe egts are 650? can i increase fuel more?

Also the cruiser goes very very very well loads of torque

i will attach a few pics of the inter cooler.

Thanks!

some pixs of the intercooler install

makes quite a big difference to the temperature

Test it on a hill first. You have to load it up.

Mine has the same turbo, fuel turned up to the max and i havent seen egts over 500C either..

 

[magnus_heydoc]

looks great
what chassis is that? 70 series?

 

[bj70cruzer]

yup its a 70series (bj70)

Thanks!

Sounds like it might be reading a bit cold. Where is the probe and how long is it?

 

[bj70cruzer]

probe is just above where the manifold meets into one and probe is fairly deep inside

egt gauge is realy responsive so dont think its much of an issue

do you think 20psi is safe seems to go good so far will it be too much for 4wheeling in low range?

on freeway at 100kph i sit at 10psi

Thanks!

 

[Dougal]

Depends where and how you use it. Gerg has broken his crank running 20psi on compounds.

!!!!!

Whoa.... hang on there a second, I was going to post that in my dual crank thread!

Yes that crank broke, but I had my crank moly coated on the main and crank bearings and I think I acidently temperd it in the cleaning and cooking process. That being said, it did indeed break. I wouldnt worry too much about the 20psi part right now as much as running that little turbo that hard without a 360 thrust bearing. Id make sure it has a 360 or turn the boost down to 15 id say. That is working that thing pretty hard. That could lunch your engine completely if it lets go where as I just have to change my crank. All bearings are good too as I only ran it for 15-20 seconds after it got broke. Doh! And I just burst a heater hose and overheated (as in the temp guage moved 1/4 inch) my 1fzfe comming back from my Oregon vacation tonight so Im in for a HG now too.. DOH!

Slighty on/off topic? Is there any difference between the 3B and 13BT cranks? Does the IDI and DI have a larger effect on loads going to the crank? Just an FYI my crank and everything else is holding up fine and it spends a bit of time on the governor @25psi

Sorry for ruining christmas.
To make it up to you, I have cracked turbine sizing and boost prediction for the Garrett turbos they supply maps for. I've also got parity with the published Borg Warner turbine maps, but no MHI turbine maps yet.

In a nutshell, the best garrett turbine is the GT22 for 4 litre diesels.

 

[bj70cruzer]

thanks for the reply gerg

I went out 4wding this weekend and was very pleased with its performance in lowrange 2nd and 3rd gear most of the 4wding was at 2000rpm and barley went over 8psi unless i put my foot down even then it barley hit 15psi

but it easily hits 20 psi when in high range driving normal gear changes at around 2100rpm

Hustly how does it go at 25psi? how long have you had it there for? also what turbo do you have that allows you to run the (is it still in its efficiency range)

Also how does a 360 deg thrust bearing help run more boost??? i guess a whole rebuild and balance is needed to achieve this?

Thanks!

 

[bj70cruzer]

ok Just re read your post 360 deg help to prevent the turbo failing due to high boost rather than the 270 thrust bearing

makes sense know!!

Also did do abit of mountain driving with all gear loaded up and in 5th gear i hit around 570degree celcius. Maybe turn up the fuel a quater turn?

Thanks!

Hey no prob Doug. I looked into that turbine stuff and wow is it kind of confusing. Makes me feel like a tard actually. I think ill mess with VNT turbos just to avoid having to learn those new tables! Actually scratch that, vnt is only housing stuff.

Before you turn up your fuel id look into that 360 bearing. In all serousness it can majorly ruin your day to suck the compressor into your engine one piece at a time.

Is your turbo new? rebuilt? Old? They are really well built little turbos, but your pushing it much harder than designed and you will be running major backpressure as well with that boost. if you really want boost you might look into swapping out the turbine for a tdo4h and do the 360 bearing at the same time. All td04 parts can be mix and matched to make custm set ups.

Think that was enough? I had mine up to the start of the red a couple times when my rad was plugged and had no issues. Sounds like its 1HD time

Both of my Volvo TD04HL's had factory installed 360deg thrust bearings. Have yours not Greg?

Yeah so I mistakenly thought that it didnt due to all of the failures associated with high boost like this. It seems that they do indeed come with 360s, but the aftermarket 360s come with larger facing areas and dual oil ports where as the stock ones come with only one port. I still think it should be upgraded if you plan on running 20lbs. Failures with boost like his are well documented, and gassers dont pull hills in summer boosting 20lbs for an hour to do it either. Their just jumping around town curtsying to each other.



So there is this rather interesing little heater hose on the 1fzfe just under the intake manifold located in such a way as to be completely inaccessable unless you take the entire intake manifold off it seems. Well that little bastard blew open pulling a hill about 50mi from home after a 1k mile oregon trip (just got back last night). So the temp guage started to climb where as it didnt at all the entire trip and I absolutley whipped that motor silly pulling my trailer. Scaled in at 11000lbs truck and trailer. Well it barfed all my coolant out all over the rest stop parking lot as the temp rose to just before the red when I shut it off. I actually thought my HG went as it really looked like the coolant was spewing right out of the side of the engine until I saw that little bugger of a hose. I prayed and managed to limp it home with new coolant (I brought 3 gal just in case ) and the rad cap off. Worked really well and the engine temps never rose all the way home. If I had a 1hdt in my lap right now, I can honestly say I would go without sleep until it was installed as I dislike this engine so much. That being said, I feel compelled to turbo the s***e out of it to honestly say to my wife I have done all I can with it before we enter into negotiations regarding a diesel swap. I already have her part support with the 25l/100k milage towing (9.5mpg). The only up side is that I get yet another guage to watch when pullin hills cus its an auto.

I got a Gturbo modified CT26, runs great, been on about 2.5 years I think.

I rebuilt mine with a stock rebuild kit including thrust bearing, I guess well see how long it lasts.

Ah ya blew the PHH (pesky heater hose) good times. Is the HG actually shot? For reference my truck gets 25L/100kms in the winter unloaded. Fight the urge to go turbo petrol and come to the dark side.

 

[gerg]

If you want lots of boost like that you might want to upsize your turbine more to an H or an HL as your backpressure will be quite high. You might consider measuring your drive pressure to figure out where your at. Would be good as no one has done it on that turbo before here.


Ahh yeah the phh. What a cute way to describe a very dangerous little do dad.

OK so if you get that kind of milage I cant really expect to get better than the 14mpg unloaded I get. That sucks. I guess its magnet time! Im getting unusual amounts of moist exhaust after truck is warm but its not sweet, even on hot dry days I get moisture out the tail pipe. Not pushing coolant, but the clincher is that its loosing about 100cc weekly. Oil is fine. High miles with the stock gasket makes me highly suspicous though. I finally disabled the egr and the misfires have gone. Nice too as i did it just before my trip as a last resort. Weird thing too is that it actually idles better after I overheated it. I dont like that. I think its screwing with me. I also need to drive this underwhelming engine for at leat a year and dont need my wife lecturing me on how unrelaible landcruisers are if the HG goes when were getting groceries or are up some snow coverd mountain or something. If I turbo it at least there would be a reason for the bad milage. Right now its a loose loose.

Lets nest a compound onto your isuzu putting 40 psi right next to your brake booster. There is tons of room, well if we put one turbo in your wheel well that is I guess. I know it can be done, I saw a picture on the intraweb for crying out loud!
