Tuned IDI vs VR6.

[Jaceb-GLI]

None of you guys know what you're're talking about. This guy has it figured out for all of us. :-)

[Jaceb-GLI]

P.s. You're going to blow that K14 up using 22psi.

I HAVE NO PROBLEM PASSING PEOPLE IN 5TH GEAR AT 55-60 WITH AN AVX. Longer ratios are NOT GOING TO HELP YOU. Just thought I'd make sure you don't need glasses.

I DO NOT HAVE THE GOV MOD DONE AND IT PULLS PAST 3K...Your theory is very flawed.

[jaed_43725]

Jaceb-GLI: I will not blow up the K14 @ 22psi. Because I am not there all the time. Its only for short periods of WOT.
Longer ratios will help because they will put me in the powerband of the engine. Not at the edge of it as I am now.
You do not understand what the gov mod vs. the fuel pin are. The gov mod allows the engine to rev past the factory point. It does not mean you will get proper fueling past a certain point (that point in a 1.6TD as I already stated is about 3,300 rpm).
Also if the fuel ramp and pic were not a big deal then why do Cummins guys change them out and why does Giles custom grind them? You need to learn a lot more.

bajacalal: as I have stated before my spring is shimmed to set the gov back.
My diesel shop has lots of experience with VW IDI engines as well as TDI.
And I dont have much hills around me so passing people on them is not an issue. Take not that my trans already has .71 5th gear. If you had read you would see its a ACH code.

theman53: Read what I said about the gov above.
I already adjusted the MBC. You really are not understanding the MBC. Different springs are for different levels of boost. Why? Because the body of the MBC can only be so big so you use different springs with different rates to adjust within the amount of travel given by the body of the MBC.
And no the turbo is not out of breath. I have plenty of air. How many times must I say that? I am not rolling coal at higher RPM's. If there is not smoke then you are burning all your fuel. That means you have plenty of air at a given RPM. The K24 is entirely to big for the 1.6TD. It works on the 1.9TD. And if I could adapt a VNT I would.

I'm tapping out on this one. Something about drinking horses and water....

Lol.

I don't want to be mean or condescending, jaed_43725, but the attitude you've consistently displayed is more in keeping with the Vortex forums; there are a number of VERY knowledgeable people on this forum, several of whom who have tried to help sort out the problems you seem to be experiencing, and you're telling them that they don't know what they're talking about. Makes me wonder...

My 86TD (1.6 idi) came stock with a K24...

[jaed_43725]

TylerDurden: My car came stock with the K24 as well. It really is to big though, especially on the lower RPM's.
Blocksmith: I am very aware of the knowledge of some of the folks here. But when people do not read what I posted and keep asking/telling the same thing or what they refute fact such as the control cone being changed out to provide more fuel at higher RPM's. Well at that point it makes me question if they have never heard of other things to do or have always been told they can only do those limited things and to just do that or worse yet that messing with a 1.6TD is a waste of time. Their input is appreciated especially those who helped me decide that a VR6 really isn't what I need to do and its better to fix the current factory made problems.

[theman53]

Look, I will leave you with this since you seem to have it figured out...

You need to not ask your cummins buddies about these engines and pumps. The "control cone" will not fuel one cc more fuel no matter how steep the ramp is without boost, the boost pushes it down to get the fuel. The gov. mod .... how do you think it gets to fuel the higher rpms? It lets it fuel, the stock gov. setting starts to cut fuel approx 2,400 rpm and you are defueled to a point the engine will no longer rev any higher somewhere around 5,200 rpm, you shim it and you rev more as there is fuel there to rev.

If you want to run the turbo to 22 psi it will not live even if you only go there once in a while. If you push it more than 14psi regularly you will kill it. Past that same point you will not see a benefit to performance either. I don't know if you read either one of my build threads you would find out that I have a little bit of an idea of how to make these go.

Lmao!! ^^

Seriously. I have forgotten more than you will ever know about VW diesels. You don't have as good of an understanding as you think you do and you're arguing with people that have been doing this *** for YEARS not WEEKS.

Sell it and go get a Cummins or a Honda. Lock this thread because there's no cure for this guy. 22psi is 22psi guys, dont worry.

[TylerDurden]

You guys are kinda harsh...

But I see no problem downshifting to 4th when passing with my TD, I can wind 4th up to 4000rpm and hit 65-70mph quick and easy.  I can also see how the AVX can pull strongly in 5th to pass, with its final-drive.

I rekon the k24 on a 1.6 being "too big" is a matter of opinion. It won't spool as early as a k14, but it hangs in later. I suppose that's the tradeoff until you get a VNT.

I'd try cranking up the full-load and make sure the throttle linkage is pulling the accelerator full travel, before getting too jiggy with the IP or swapping a trans.

As did mine. I have only a gov mod and more advance done on this pump.. 1.6TD stock with 4S trans. Best power? (and mileage??) 3200-3500RPM Who would have thunk? Oh yeah, I also have the waste-gate disconnected, because racecar.

This engine has no issues hauling to 55-5700.. No problem. Less power in the higher gears, so it can only go that high in 1-3.

[wolf_walker]

3ish K RPM is pretty much happy town for all the IDI's from my experience. 

[jaed_43725]

wolf_walker: Thats about right. Somewhere from 2K-3.3K.
8v: The 4S is a much better gear setup than the ACH.
Tyler: I can go to 4K, but its got nothing for power up there. And the trans gearing makes a huge difference.
My K24 worked fine, but it would not spool like that K14 no matter what I did. Pulling 15 psi was a chore with that thing.
And I made sure the linkage was correct awhile back and recently checked it as well.
theman53: I have thousands of miles logged on the K14 and its still working just fine. No noises, nothing. And I check for shaft play at about every oil change. If it was going to die it would have in WV.
And if the control cone had nothing to do with it then why does Giles make custom ones?

[theman53]

The "control cone" will not fuel one cc more fuel no matter how steep the ramp is without boost, the boost pushes it down to get the fuel.....AGAIN. That boost pin will not add one bit of fuel without boost, don't believe me, disconnect the boost hose and see how much fuel you get. I have a Giles pump, I have custom ground pins...you have a turbo that is out of breath that will do nothing but have high EGT with a custom boost pin.
