Who is running a D66 with a 1.0 housing - Diesel Forum

Jerry Miller · 02-16-2008, 04:44 PM

Okay, I'd like to hear from those of you that are running this set up with stage 1's. I'm kinda wishing I would have just installed the 1.0 housing onto the D66, but I was worried about surge....Just want to hear success/horror stories of the 1.0 with Bean's turbo. Like to know boost numbers, egt's, what gearing, etc. With my 3.55 gears and 35" tires, I think I just need it to spool faster, at a lower rpm. I'm trying to clean up my smoke for daily driving.

sounds to me like you need a regear, 35's and 3.55s not a good combo if you ask me.

JohnDeereBones,
My 3.55's worked just fine with stock injectors and turbo running a hot program from Bill. In fact the stock turbo with stage 1 injectors and a 1.0 housing actually had better driveability in the low range (around town) than the D66.
No offense, but I just want to hear about 1.0 housings and the D66. I know that my gearing is not optimal, but for what I do, I plan to keep it this way. Besides just running in 1st gear at about 2000rpm's and then hammering it puts out more smoke now than it did with the stocker and 1.0 housing. At this RPM and speed gearing is not the issue. I'll even put my stock tires/wheels back on and take it for a test run......I guarantee it is still going to have lag/smoke.

i'm runnin 35's with 3.55 gears stage 2's and a d66 with a 1.0 housing and I like it. It will surge in od at certain rpm but you can power through the surge. now having said that it will spike my 35psi gauge quickly in the higher chip setting and the turbo will bark pretty hard when it shifts. i plan on putting a wastegate in to blow off excess pressure when possible. I went back to 1.15 housing on beans recommendation but didn't like it. I like the quick spoolup with the 1.0 and can control the surge/barking problems with my right foot. my housing is a wastegated housing but wastegate is disconnected.
just my .02

I've thought about going to 3.73 or 4.10 but hate to lose the gas mileage and you can overcome the tall gears with hp

Darth,
Thank you very much for answering my question. I wonder if a 1.0 is just different enough from the .95 to keep surging from happening. Do you know what mph or rpm you get surge? Is it always at that speed or only while under heavy load or accelleration?
I really wish the inlet adapter had 4 bolts instead of 2 bolts and 2 studs.....I think you could almost slide the housings off without turbo removal if this was the case.....maybe.

I would still like to hear from others as well.

Darth,
One more thing...how is your smoke at lower speeds. I only have stage 1's so I know this won't be an apples to apples comparison.

Darth_Stroker · 02-16-2008, 05:42 PM

as long as i'm not lugging the motor it's virtually non existent. little puff if i jump on the gas till the turbo lights, which is pretty fast with the 1.0. i had my chip reprogrammed to change the tranny shifts to keep me a little higher in the power band, and my uppipe donuts are leaking pretty bad right now so it should be even faster when that problem gets fixed

Jerry Miller · 02-16-2008, 06:42 PM

Darth,
Thanks for the info on the smoke. Can you explain a little more about the surging What rpm's or mph? Does it to it all the time at that speed or just under load at certain boost levels? I'm trying to determine if I can live with a little surge.
Thanks and sorry to keep asking so many questions.
Jerry

Darth_Stroker · 02-16-2008, 09:21 PM

I have not towed with this turbo and housing combo but unloaded I'd say the surge happens to me usually in od when i roll into the gas to pass etc. i usually just hafta give it a little more peddle and it stops surging. probably somewhere between 55-70 mph as far as surge. Barking is another issue. that happens at low speeds on the 1-2 shift usually if i'm on it really hard and I don't know how much boost it's pushing cause it pegs my gauge as stated before. now maybe when I install fuel system and finally get my 4 line stealth in I may be able to go back to 1.15 but until then it's 1.0 all the way for me. I don't drive the truck everday and don't hammer on it all the time when I drive it but I like to play a little and I have had newer tunes but I don't like fogging the highway especially when I'm trying to drive like a civilized human being and I don't like having to floor it everytime I accelerate to clear up the smoke so for me the 1.0's the way to go. bean didn't recommend it the last time I talked to him but i'ts been over a year and no problems so far.

Jerry Miller · 02-16-2008, 09:28 PM

Darth,
Thank you very much......the 1.0 housing is going on tomorrow. I am in the same boat as you....I don't want to have to have my foot buried to the floor in order to keep the smoke under control.
Thanks again,
Jerry

Well, I went out this morning at 6:30am, removed the D66, installed the 1.0 housing on the D66 and reinstalled in the truck and was done by 8:45am. Not bad since my truck is parked outside and it was dark in the engine bay!
Anyway, the 1.0 housing made a huge improvement. It still smokes more than I hoped on the bottom end, but not nearly as bad as the D66/1.15 combo or the stocker/1.0 combo.
I highly recommend the 1.0 on the D66 if you are using your truck around town and aren't in the super hot settings all the time. One thing I did notice when comparing the D66/1.0 combo to my old stocker/1.0 combo is that the boost gauge has more flutter with the D66....which I kind of expected.
Once my intercooler goes in, I may have Tony tweak it a little, but for now, I'm pretty pleased.

I thoug Beans specifically cautioend against a 1.0 on the D66.
However I think they make a D66 with a 1.0 and wastegate for the SD's?
SD turbos are adapatble to our truck I think...is that a pain in the axx?
Has anyone tried this combo?
This would be something I'd think about because I liked the realy boost aspect of stock/1.0 before I got my D66.

Dieselfever78 · 02-17-2008, 01:20 PM

A stock SD turbo is a downgrade on an OBS truck IMHO. . . or at least a waste of time and money.

Now with a drop-in unit it would be feasable, but by that time you could have almost bought an H2E

Don't get me wrong, I think the D66 is a great turbo, but for people like me that are concerned about low end smoke, the D66 NEEDS a 1.0 housing. If I could not run the 1.0 housing on the D66, I would return to a stock unit with a 1.0 housing and just rebuild it as needed. I plan to keep the D66 around 35psi max boost most of the time, so I feel comfortable with the 1.0 on it. Once the intercooler comes in, I will re-evaluate my needs. I may get Tony to do some tweaking.

Actually I meant a D66 for the SD which I think comes with the 1.0 being adapted to the OBS.
