appreciate the feedback man. so on my setup, since the actuator is (unfortunately) custom mounted with a custom length actuator shaft, 69% happens to be the mechanical max of the lever (might actually be low 70s, but I wanted to err on the side of caution to avoid overloading the servo). I...
Finally got around to getting some logs with the new gtd2060 turbo. If you compare these to the logs with the stock turbo earlier in this thread it shows this setup gets to full boost about 500rpm sooner (1900rpm) on a 3rd gear pull from 1000rpm. It makes good useable boost as low as 1400rpm...
Really well! It'll actually start building a tiny bit of boost as I'm slipping the clutch to get going in my uphill driveway. Really helps it takeoff without leaving behind any smoke. I went from 30.5x10.5 bfg ats to some 31.9s at the same time as the swap so i didn't get a big fuel economy...
Redid the exhaust and intake piping to line up. Went with a bellows on the exhaust to replace the flex joint. Hoping this might reduce some of the noise/vibrations i was getting. Still need to remount the turbo actuator, the stock actuator location interfered with the exhaust manifold.
I've been debating a new turbo for awhile and finally decided on something new. Big thanks to anothernord on the forum for sharing his experience doing the same turbo swap.
I went with the GTD2060vz as it seemed to fit what I was looking for as far as quick spool (lower than 1800rpm) as well...
Update, I forgot to mention that after doing all the work in the July timeframe listed above; checking the rechambers, trying a 3rd? set of nozzels etc, the fix for my blue smoke during warmup at idle was changing out the delivery valves. They act as a check valve to keep the pressure in the...
great data, thanks for posting that up. Out of curiosity, can the nozzle position/cmd be set less than 10% ? I assume emp is getting pretty high at that point so maybe it's not worth setting any lower. Also does pw% and nozzle % trend linearly?
Thanks for the feedback.
good on the prechamber balls.
Glow times are pretty long (much longer than the DSL1 defaults). 60 @ 13C, 100 @ 8C for reference. I've replaced, and then checked, all the plugs to make sure they're glowing orange as well. Even after an 8 second pre glow I get a...
Been following some threads over on Superturbodiesel that made me wonder if my smoking at startup had something to do with a prechamber issue. Since I had never checked them I decided it was time to cross them and a compression test off the list.
The compression test numbers came out as...
O wow, sure sounds like the spool is noticeably better. It might be tricky if you cant manually lock your torque converter, but I'd love to see a boost log vs rpm to compare it with those ones I took with the kkk turbo.
I love how cheap the gt2359s seem to be, but if I can get boost 400 rpm...
How are you liking the gtd2056 turbo? does it spool noticeably faster than the gt(a)2359? ...if you can't tell i still haven't decided on a turbo haha. I believe jav had a gtb?2056, and while saying the spool was good, said he ran into backpressure issues above ~4000rpm. have you had any...
Vadim thanks for posting up your setup, glad to know I'm not the only one looking for a bottom end torque curve. A quick search seems to show the gt28 flowing more than the he221. I'm guessing that smaller exhaust housing you have helps with the spoolup. Next time you get a chance to drive...
I've been starting to research a new turbo for the truck to improve the low end as much truck is a manual and doesn't get the benefits of a torque converter allowing the rpm to slip up. There is a ton of information regarding turbos for these engines, however they seem focused on people using...
