Replacement turbo

[mfgguru]

With you all the way Slim!

Can we summarize the advantages to this new turbo? More MPG's?

Also just a side note, we have applied for a lock on the idea for the modifications, proprietary ideas.

A lot of testing went into this, I am not into lunching someones engine. So; just a side note to someone buying a knock of turbo that has no testing, you may lose your motor to compressor shrapnel from the cheap turbos.

This has not been a overnight en devour, a lot of work and research went into this project to come up with a safe and reliable reasonable priced replacement turbo for our 6.5.

Hey RCPD followup to Slim's question, something to consider if you are selling a Chinese knockoff yourself,

the turbos chosen by Slim & that are also being tested on our vehicles, was because we have a IC between the turbo & our engine, there is some good China stuff and some bad, in event the turbo we chose lunched itself the IC would offer some layer of protection, we have been very cautious to not grab the first one we looked at. Also we made no mention of the experiment except in passing until we had proven one to be safe, I'm confident recommending the Mitsubishi turbo is good for go, high confidence in same China turbo Slim has tested, I'll be able say more about it once it is up and running on my truck.

But since the China turbo has not been on my truck yet I can't comment good or bad on it, I expect to see it sometime this week for install on my truck for testing, if you are doing your own thing just be careful before taking orders on them that you have one fully tested that isn't going to harm somebodys engine if it lunches itself.

Did I miss something here ???? RCpullerdude are you saying you are selling the turbo???

Thought Turbine Doc, Myself and Hank1948 had put this together. Must have missed something?

Here is what I sent to Slim in reply to PM:

"You read it wrong. I'll let (you) know (that I'll buy one) when we (the forum) have a price and (know when the) delivery/payment due date is. lol"

Let's stop and ask ourselves: "How is a 16 yr old kid who is interested in, obviously knows nothing about, and has been asking about this turbo come out of nowhere, literally overnight, and get something together with a mfg company?" Little far-fetched when you think about it...

lol

 

[packratt]

Put me on the interested list. Can't positively commit until the little things like pricing are nailed down.

 

[sshewins]

I got that one right? Don't tell the wife, she'll spect it all the time LOL

I'm with you guys, make a profit! How many of us have the knowledge and resources and contacts to pull this off? Far as I can tell, you've done a ton of leg work and have invested more $ than we use to fill our tanks (which is way up there too)

 

[Pillow]

Put me on the list as well. If the price is right of course and a quality kit... As always I would need two conversion kits.

Thanks for the R&D on this upgrade guys!

 

[Slim Shady]

Yes thanks to RcPullerdude, just got a little gun shy. Lots of folks worked on this project and hated to see it come apart just before it went live. When you have a pet project sometimes you get a little over protective. Probably been around to many diesel fumes lately makes you kind of giddy and intoxicated.

Thanks RCPuller for clearing that up and in the forum as well. I never lie cheat or do anything I can;t back up so rest assured it will be a quality kit at a fair price.
I was always told treat people like you want to be treated and you never have to look over your back.

Honor is the only thing nobody can take from me unless I give it up, My body will be cold before that happens.

Maybe our US currency can gain some international value before its all nailed down. It'll help with the price a lot. The price of metal is climbing too. No shame in making a dollar guys. Personally, I appreciate all the info posted so far along with the openness of the experiment with the community. I keep thinking a good going through on the valve train and a fresh turbo and hopefully I can whistle to 20+mpg.

Can we summarize the advantages to this new turbo? More MPG's?

Good low end power and top end towing power. This is also with less back pressure and I saw an increase in fuel mileage from 15 mpg to 18mpg consistent at 70 MPH and 19mpg on a couple of tanks at 2268 rpm with the cruise on.

The truck get s consistent 17.239 in a mix of highway and city driving. The oil leaks have stopped and the oil seems to stay cleaner longer, not as much soot.

Back pressure in the exhaust is a killer the gm -* in my opinion is way to small for our motor if you get the engine past 2000 rpm. This is just my opinion, I couldn't figure out why my friends 6.2 N/A gets consistent 22 to 24 MPG and my truck barely could get a consistent 15 MPG. SO what is the difference. The turbo and the injector pump. HUMMM exhaust is the culprit, and yep paid off. My truck was a slug merging into traffic before now :reddevil:

Maybe Turbine Doc can give his thoughts so far.

Our dollar needs to strengthen, oil would be cheaper, more for less dollars and the turbos would be cheaper, sounds like a deal.

This is huge guys. Great work, and I look forward one day to installing one.

Monumental actually, this could be 6.5's best friend since the relocated PMD.

Can't wait to see what HEath can do to tune to one of these.

 

[RCpullerdude]

Let me see if I have this straight (finally):

This turbo will:
Feel about the same up through about 1500-1800 RPM
Be much stronger from 15-1800 and up
Tow much better
Increase milage a couple MPG
And allow 18 PSI of boost on a stock engine with no IC?

Sounds good to me. I can't thank you guys enough for going out and doing the R&D on this. Like Matt Bachand said, this may be the biggest thing since the remote PMD.

When I e-mailed Heath's sales department, Ian forewarded it to Bill, and then forewarded the reply to me. Here's what I got:

"So long as the turbo you use will produce airflow sufficient to make 15 or so #s of boost at max rpm, we can make things work well for you. Specify our GL4 progam when ordering by phone"

How well will this turbo work on an engine with stock programming? Will the lack of a heat sheild on the turbine housing have any adverse effects, mainly on the hood?

 

[Turbine Doc]

Ian, Bill, & I have discussed this as soon as the China turbo gets here, it will go on the truck, then I'll be sending the Mitsubishi to them for tweaking with HP-4 use, may not need anything, except slight shift point adjustment for auto trans, Slim is running a 5 speed stick with 4:10's, when I drive with my foot out of it running 70-75 mph 20-22 mpg is what I'm seeing, before I had to run 60-65 to get that, last week I drove to Waycross Ga, Jax Fl, and back devil may care on how much fuel I burned/how fast I went, 75+ mph more than once; couple of jaunts to 100+ mph to see what it would do, that kind of "play" used to get me into 14-15 mpg territory, I was getting 16-17 mpg, it is a run I've made often last 2 years so I have a pretty good gut check of consisent fueling, how much further I went before topping off main tank from my 50 gal "range extender tank" in the bed.

Bill & I were discussing yesterday performance loss with IC vs WMI vs hauling water, with his WMI this turbo there might be some really big things on mpg forefront, with minimal performance loss. Stay tuned folks.

 

[mfgguru]

Well, WMI is out for me, I don't think it would work in our climate (I hate our winters). I would be very interested in your thoughts on ATA vs. WMI and the pros and cons on each. Maybe we could start a thread outlining this. BTW, will the tune Heath is working on be sufficient for the Chinese turbo? I think if you guys can get a bolt on unit, that is the way I want to go.

 

[Turbine Doc]

Patience fellers these things take time if done right, we don't want to cobb up a bunch of stuff half azzed, once I run the China turbo I'll know the suitiability of bolt in, comparing it to captured data I have from the Mitsubishi which is bolt in, but I like the rest of you want it refined as best as possible, so I'm sending it to Bill to see if they can find any refinements to be had, possibly not, all of this will be back burnered to the Bonneville project so I'm not pushing it hard,. all in time, hang tight

WMI might not be out, may have to add more alchohol to prevent freeze, but as far as I can tell from what Bill describes it doesn't spray unless needed, so in winter low OAT may negate need or activation of spray.

 

[sshewins]

WMI ratio is 1 gal wash solvent to 7 gal water (and only the 0* to -20*F stuff; the lower temp stuff like -25*F might have anti freeze in it which is a NO NO!!)

In extreme temps, the ATA might be a better choice (nothing to refill or run out or remember) to reduce IAT's. Plus the WMI only comes on when either the EGT's get to high, or boost goes up. Not on all the time.

When's Bonneville again? More specifically, when's the day after. LOL

 

[mfgguru]

I didn't mean for this to be an I/C thread. Sorry guys! Lets keep it to turbo talk.

 

[Turbine Doc]

I just drove my HP-4/TM/GM-8/4" exhausted Burb last nite, first time in a while, the GM-8 combo is zippier off the line over the TD07, so when some ask what is down side, it has somewhat lessened off line performance, up side is better mpg, I still haven't towed big with my TD07 yet but Slim says that is where the TD07 excells over GM turbo. When he's compared the 2 in towing routine, my empty driving tests show the TD07 does more with less pressure wise, than the GM turbo,

GM turbo has to work harder to move same cfm of air builds quick on bottom end drops off at top end, vs TD07 making adequate boost on bottom end and better boost at top end, this isn't a turbo if you are looking for best 1/4 mile times, it isn't any worse than a GM set with stock programming, by seat of pant driving my Burb will outrun my truck I think off the line, but truck will outrun it 30+ mph I'm thinking.

 

[Turbine Doc]

It's in China turbo installed past weekend, same backpressure response & numbers to the Mitsu TD07-22, but far better bottom end response than the TD0-7 almost as spry as a GM-8 with a TM on it.

Next item for business will be to pack up and ship the TD0-7 to "Boys at Heath" to tweak it, I haven't done any mpg comparisons as of yet been having too much fun hotrodding it & putting it through it's paces.

It does have respectable volume of black smoke until turbo starts feeding air, once spooled to about 2 psi boost smoke clears up, which I'm confident can be optimized with tweaking of the program.

Here are some pics TD07 in picture notes are Mitsubishi turbo, CT index are for China Turbo (a TD07 clone, "sort of")
