30PSI Pulls and Fuel Pump Tune!! - MK1 VW Rabbit Turbo Diesel (4K)

[@TUBEYOUTHETUBE]

Love it that you guys in the US also enjoy tuning those old turbo diesels! Ive got a MK1 Caddy (rabbit pickup truck) and also tuned the pump a little bit, it was quite a common thing to do back in the days here. Greetings from germany

[@OliverFetter]

Cheers to that 🍺 I appreciate you sharing!

[@OliverFetter]

What do you use your truck for?

[@TUBEYOUTHETUBE]

@@OliverFetter I use it for carrying my motorcycles, construction materials and everything that does not fit in my mk2 Golf. I also have a removable camping drop-off cabin I use on holidays. Pretty useful and cheap to maintain truck

[@Raaid0093]

I have the AAZ 1.9TD engine swapped in my mk2 Golf. With K24 turbo. heavy duty clutch. Rover tdi boostpin. and Mercedes van intercooler. It goes good! The best i could get with my setup is 6,9 seconds from 0 to 100kph. If you want more power. You can try a Giles pump. They are mechanicly different in the inside with a larger rotor inside. I didn't do the governor mod. Only downside is. After 2 pulls. The coolant temp rises. I used a new large radiator. Never added coolant. But i think it something to do with EGT temp.

[@OliverFetter]

Sounds like your working on some dope stuff man! Keep it going.

[@OliverFetter]

Love it man! I have a guiles pump so I actually haven't had to do the governor mod? I would recommend it though, it really wakes up the motor since there is ample fueling throughout the whole RPM band

Reindexing the throttle can buy you so much more power than gov mod.

Put spacers in or remove them?

[@ralph9987]

great explanation of the fuel adjustment. is this setting for idle or or will it affect higher rpms? my cummins b 3.3 non turbo has some power loss and won't rev more than 1800rpm under load. fuel filters are clean and clear. cheers

[@OliverFetter]

Turning in the fuel screw increases fuel delivery across all rpm's, that's why you need to turn the idle speed back down to balance it. I'm not sure how to diagnose your problem but I feel like start by making sure the timing is within spec, could always make a Diesel run slow/weak. Turning the fuel screw in will perk it up regardless 💁

Can you tell me something...I got a spare pump from a automatic mk4 tdi with 110hp with the bigger 11mm injector elements...can they fit in a AAN mk3 pump that i plan putting on a mk2 1.6td with a bigger turbo and some other shit(3in straight pipe,intake,arp studs,1.9 head....)

I have not a damn clue my friend 🤯 you'll probably just have to give it a try!!

[@dwscooter]

did you modify or block off the blow off valve? i just finished installing new parts on my cy engine. but the blow off valve is limiting boost at 10psi. the new turbocharger should be higher.

[@OliverFetter]

Yes, when I was using the TD manifold I think I replaced the adjustment screw with a longer bolt so it stays entirely closed off 👍 that's cool!

Like the straight forward description of the two screws and the rev hang. Is the diaphragm on top of the injection pump just for turbo diesels?

[@dylanfox7077]

Yeah

[@herkybc130]

@@dylanfox7077 I'm gathering turbo injection pumps are rare while normal aspirated pumps seem to be quite common. What are the drawbacks of running a normally aspirated injection pump on a 1.6 turbo diesel? Less horsepower?

[@OliverFetter]

Yees the diaphragm is the differentiator

[@OliverFetter]

@@herkybc130 **steals reply (sorry 😬)** the diaphragm is what matches fuel to boost, ie with more airflow you need more fuel as well to have more combustion.

[@LR90_200TDI]

You can adjust the fuel to match full boost but the down side of having no boost compensator is that when the fuel is adjusted to match full boost it will be smokey when off boost

[@davidross-oo2vh]

Turn up the High Boost enrichment screw on top of the injection pump..

You can use a 6 speed transmission out of a 2019 gasser jetta. FYI in case you ever want to swap

[@itskarl79]

I’m just curious your thoughts about putting the older mark one style lift pump on a newer 1.9 TDI, it seems like you have more tune ability with the older style pump.

[@OliverFetter]

Depends what you're looking for, generally a 1.9 can make more power because of the computerized pump - makes it easier to provide more fuel. With the 1.6 you start to run into rev hang as a limiting factor for fueling because it increases in a linear fashion

Little help here. so i have a 1.6td pump that i recently putted on my 1.9tdi engine. Before doing so, i swapped off the 10mm plunger from the 1.9tdi pump and place it on the 1.6td pump. I adjusted the boost pin about 90degrees. For some reeason, i cant get it throw a little smoke, becaz the rev screw is backed all the way out. So i cant even adjust the fuel screw anymore. Anything as what might have caused it to still be throttling high even with the rev screw backed out?

[@OliverFetter]

The fuel/power screw is a essentially a multiplier of your throttle position. So let's say you bottom out your idle setting and it's providing 2 units of fuel, then if your fuel screw turned in (well say that's a 3x multiplier) then you're still getting 6 units of fuel not 2. Make sense at all?? Bottom line you can't run that much fuel screw with those settings - you could try playing with the way the throttle is indexed to the pump.

Ya gotta CRANK the fuel screw till your getting rev hang, then turn your idle speed down, then repeat.

@@OliverFetter yea the wastegate should be enough. I plugged my old 1.6td with a rubber expanding pipe plug and it worked great, made a little bit of room too.

I wonder what the EGTs were at 30psi. If it hits 30psi without getting to 1200F on the EGT gauge you are pumping in too much air and creating backpressure. My Rabbit TD actually goes faster at 15psi than if I run it up to higher boost. I've had it up to 35. It went slower.

[@OliverFetter]

You're on the ball Oscar! This is exactly what I found since this video. I actually blew this turbo up bc the overspool + back pressure was so bad. Now it makes closer to ~24 in a much smoother more powerful way.

Great stuff man! I have so many questions 😂 I own a mk2 Jetta that has a 1996 AAZ 1.9 swap. Been working on it none stop and you videos have definitely helped. Maybe there’s a way I could ask you everything somewhere else? Either way I’ll start by asking about the Giles pump. What did you have him make the pump too? When he asked me he said he could set it to 10 or 15psi, of course I said 15... now I’m seeing guys run 32psi on these engines. How much is it gonna take for my pump to reach that? Do love your car and your content!

[@OliverFetter]

Yo! You could dm me on the gram if you have a ton of questions @ollys_auto. I haven't worked with any 1.9's. I had Giles remove the governor when he rebuilt it and set it up for 20+ psi if I remember correctly. I appreciate the hype! Glad you like it
