200Tdi General performance question

Ok gurus I have a question. Now I have seen performance posts about 200Tdi that are all over the place. My 200Tdi in a CT110 w full roll cage, fully loaded, on 265/75/16 BFG MT's is running well finally. I can cruise at 65-75 on the flats and climb at 45-55 here in CA on the long climbs to Tahoe. Engine temps are no longer an issue since turning the max fuel screw down 2.5 turns and setting the FIP timing with a 9mm drill bit, basically run less than 200F even on 100F days while climbing. EGT's can get to 1250-1300 (i back off at 1250 and hold 1150-1200). I have the fuel diaphragm set to "max" and some minor adjustment to the smoke screw. I don't see any black smoke while cruising, occasional puff at start up, and then hazy brown/black smoke under load. As there are no Tdi experts close to me and no tdi's to compare to close to me, any suggestions to maximize engine performance? I'd like to be able to hold 55 up a 6-8% grade and maybe tow a smaller trailer. I do have the boost at 12psi I think. My VDO gauge sits at 2psi with the truck off and hits 14psi under load. I also have the double width allisport inter cooler and AC. Here's a video of her at idle after a short run, not sure if it helps or not.

Thanks!

Chris

A vvt, or vnt turbo, or propane. Never had to climb into the Tahoe basin from the West/Truckee side but have done it from the Nevada side and remember that being a 7000 foot or so pass. Not sure how much more you can get out of that engine without pushing more air in so you can give it more fuel.

I have spent some time tuning my engine. I think you have found the limit as mine runs pretty much the same as yours. Although I dont have and have never had cooling issues.

What transfer case ratio do you have on your truck?

The only way to more power than what you have is more boost and then fueling to match. The stock turbo does not do a lot more, but you can get maybe 18 psi, if you want. Beyond that, you need a larger turbo.

If you raise the boost you should be able to keep your foot down without the egt's getting as high as you see now. I don't know if you'll notice a difference in power but if you've maxed the fueling out adding air should help. My truck is much lighter than yours but I don't see less than 55 with my foot all the way down on long grades on the way to Tahoe. My egt's top out around 1150-1175 at about 16-18psi of boost.

I would be careful as think you are at the engines limits Chris.
While 14 PSI is probably OK, much more boost and you'll surely blow a head gasket.
Once had a waste gate stick after installing a manual controller on an Iveco 2.8 TD and the boost started shooting up to 19 PSI.
Next thing I knew the head gasket had blown.
Be safe and stay around 14 or 15 max.

The thing I really like about the Isuzu 2.8 Liter TD engines we also run is they have a safety pop-off valve that dumps the boost at 18 PSI.
It's a nice safety feature that saves one from having to replace the head gasket.

With the stock turbo there is nothing to worry about. You can throw away the waste gate and you won't get over 18 psi. I've run at those levels for 10 years and no head gasket problems. EGTs are what is important.

out of curiosity what did you do to modify the waste gate to get to 18psi? I have seen lots of posts where guys are using a modified brass tee with a spring and ball bearing as a check valve. just curious since I am not sure you can get much more then 14psi out of the stock waste gate. Mine runs at about 14psi and has been shortened up about 5 turns.

Just shorten it more. You can also be limited by fuelling. You need enough fuelling to produce boost.

I have a Boost Valve but it is not needed.

Fueling is not a problem. Just didn't think I could get the arm back on If I made it any shorter! It is already very tight! I can watch the boost gauge climb rapidly until the waste gate opens.

Open the waste gate with a bit of air and then hold it open with visegrips. Then unclip and adjust.

I just want to thank everyone who replied. As I don't have any local comparisons it's nice to know I'm doing alright. It's because of all the sharing (and caring ) that I've been able to get her where she is. Any of you who have read my early struggles with power and running hot etc will know how finally getting the truck in the sweet spot feels. So, enough with the Oprah shit, pints to anyone who visits Livermore (SF Bay Area) just let me know when you are around.
