- Gday everyone and welcome to the 2nd episode on the supercharged ZD30 Nissan patrol. This episode we push to get the system working better in hopes to make more boost and get the HP figures the turbo made.
Feel free to get in contact via email

Love the experementing with the supercharger found it real engauging.
Good to see you accually questioning the old turbo vs supercharger war!
Lol yeah unfortunately the supercharger lost in this case.
What a bugger this didn't work BUT we all learned a few things! Cheers.
Can't say we didn't give it a good go though 👍
Late to the party on this one and I can see the issues you had but also some you are still having and may have missed. Eaton blowers were good for boost on Petrol as they are just that, petrol and rarely run at WOT. The ZD30 on the other hand is a 16-valve air pump that moves air pretty good (still a lot of room for improvement, especially on the intake manifold) and being a diesel, they are ALWAYS running WOT. The first is to get rid of those aweful autoflop guages, their display is junk, get some decent analog needlers in there to see whats really going on. Secondly, make sure the idle bypass valve is jammed shut and no pushing open which is needed for the spark needers. You found the issue near end that the drive was slipping on the shaft, TIG fixes a lot. I did notice the lobes and housing were showing a lot of wear and will be killing some performance, certainly no teflon lobe seals.
Aftercooling, yeah, didn't see what was in there or the plumbing but these thrashers do just that, thrash and they make a lot of heat. A good trick with blowers is water injection PRIOR to the rotors there in the inlet port. This helps keep the lot a heap cooler and also helps a little with the lobe sealing. If you take option of a little meth as well, now you are adding some oxygen bearing fuel to the gang-bang. Although, I would run water only on the blower feed, keep the 50/50 W-M for spraying around the last rubber coupling on the intake plenum.
Moving from the 150mm drive pulley to a 200mm will give some extra spin but so would ditching the alley driven pulley to a smaller steel sucker. 150mm @ 4000RPM into a 60mm is 10K RPM on the blower. just changing the blower driven pulley to steel and 50mm will see the blower now spin at 12K RPM. As there are guys pushing these to over 18K, moving to a 200mm bottom, 50mm top will see 16K on the blower @ 4000RPM engine and 17,600RPM @ 4,400RPM redline. Just for a rough bit of maths, I figure you are getting around 1PSI per Rev. The water spray will see you better on the rollers.
Ultimately, a big-flow snail pushing into the blower will see the clutch smoke. Of, BTW, don't waste your time with bloody Dawees/tillux crap, use a boost actuator for smooth, easy control if a snail comes back.
Thats a substantial write up mate and thanks for taking the time. This setup was removed a fair while ago though and a vg turbo was put in its place, using a different actuator.
Found this really interesting mate but yeh diesel and supercharger doesn’t really go together. Interestingly you would need more boost than you ran from the turbo to achieve the same power at the wheels due to power losses from running the blower itself.
Still glad you know what your doin bloke, cos it keeps blowin over my head so far up I don't even feel a breeze! Like ya Dad, The only cold ones I get these days is the ones that I give other people. If youtube don't let me catch ya before Christmas, you and yours have a good one m8. Thanks, stay vertical Eh!
Have to have a closer look at a Detroit Diesel and see what their volumes and pressures are.
I reckon keep trying; either source a bigger charger, or go down the old-school Detroit route and flow a turbo into the Eaton!
I do have a lead on a 471 blower but there would be no way it will fit under the bonnet. We did talk about twin charging but I just do see any room or easy way to squeeze a turbo under the charger as well
@@HarpersShed Not even a factory sized turbo? Surely you could make one fit and feed it into the M90.
@@neardood1 I'm sure I probably could make something actually fit but because its dad's daily 4wd there is too much to go wrong. Limited budget makes it hard to. Not to say we can't do something like that if I ever get a toy 4wd
If you don't try it ya never know what exactly is going to happen, now we know 🙂 thanks for that it was a fun ride.
100% mate, That's what it was all about. It would have been cool if it worked though
Would be really cool to see what it could do with a bigger charger. But yeah, can see all the reasons that would be an issue.
Stop stuffing aound with the old mans Patrol and get back to the BMW - LOL . Interesting episode as I learnt a few things about superchargers thanks!
All in good time, I have been pushing hard with the BMW but hit a few issues with parts. Hopefully that's behind me now and I will have a video out soon with it making noise 👍
I've watched this with fascination and must admit to thinking you'd be flogging a dead horse or in your case a dead kangaroo. What you found out is why you don't get any supercharged diesel cars, firstly superchargers as you know are mechanical and straight away you're losing power also fuel economy drops, turbo chargers run off waste gas so no power loss but can suffer from turbo lag. Now to get around this problem starts getting expensive and complicated as you would have to create a supercharged turbo set up and to be honest it's not worth doing in your situation but would be great entertainment for us, so just stay with the turbo set up plus working with a turbo supplier is even better as they won't want their product getting a bad name so should go the extra mile for reliability. Win win situation. At the end of the day it was worth a go, as they say nothing ventured nothing gained and it was enjoyable to watch. Oh just one more thing, I'm with your dad when a cold beer is involved 😅. Great engineering and full respect for endeavours. Gary 🇬🇧🇬🇧
Hi Gary, you dead right with the parasitic loss of a charger however it's not as bad as one would expect in this application and in a petrol situation they return far more than they take. I think in this case the charger just wasn't big enough. Turbo's aren't always free though. They use exhaust gas as you mentioned but that comes at a cost of restrictions and back pressure in the engine making the engine less efficient. Like the charger though that give back way more then they take and your also bang on with just going back to turbo. Twin charging would be cool but just not practical like you said.
My crd zd30 basic setup with exhaust gfb v2 boost controller 21psi factory garret turbo 175hp 470nm been super reliable for years. Turbo upgrade wise ufi is a great option or the demon ones are good for a budget. I thought about injector and turbo upgrade but $$$ vs gains and reliability makes no sense for my purpose thing goes everywhere as is. Great to see experimentation and keen to see where this goes with new turbo!!!
That's very good power numbers for the work you have put in mate. We are looking at a custom vnt turbo at the moment but not set on exactly what one yet.
Awesome content! I like your fab work and way of explaining as you go. I'm currently planning on putting a M90 on a 2.5L NA diesel, and I'm excited to see how it works. It's not about power for my part, so it will probably not be comparable to your project, but you have some good information that might help me anyway.
Keep up the good work, I'm subscribing 🙂
Thanks mate, hopefully your project goes well. You should see better results with a smaller displacement engine then I did.
I wouldn't expect a lot more boost into a 3 litre than you get in the factory 3.8 application at the same charger rpms.
Almost every time I had a theory about what would happen in this project I was wrong, I thought the smaller displacement would net a higher boost but it didn't 😞
@@HarpersShed it should be about 3.8 / 3 times higher assuming similar efficiency by my guess so maybe 1.2ish timed
It is making more then it did on the 3.8l v6 but not enough to make me think it will do enough up in the higher revs
cool vid, very entertaining.
Thanks mate glad you enjoyed the video 👍
You've used a way to smaller supercharger by a long way it's just simple volumemetric math and I can see other things that that engine wouldn't like with regard to load I'll put money that the nose of the crank wouldn't be happy with the stresses if there was a bigger supercharger as a soul sauce of boost but have you thought of sizing the supercharger bigger and running a turbo? I've seen a few channels do this with good results, Desiel Pump UK has just done a video with a OM606 with a supercharger and turbo charger and I've seen a few channels in the US do it with good results but thing's need to match up in regards the purpose like having a supercharger that is volumemetricly up to the job and then the larger turbo can take over in its efficiency range
could your issue not be the fact that diesel engines run much higher compression. so you need to be supplying more air than a petrol engine would need? If i recall the charger came off a petrol engine.
i hope you get it to work as I would be interested in doing something similar to my patrol.
That is very possible mate, it could be that because of the higher comp as you mentioned that it takes more force to make the positive pressure. Definitely something I hadn't considered and worth doing some research on. Thanks for your comment 👍
I have a CRD ZD30 and have been looking at supercharging it for a little while now, so I am hoping this works
Unfortunately mate I my experience has shown that unless you have a much bigger charger then the M90 it won't flow enough air. Perhaps something like a procharger could work as they spin at much higher rpm than a lobe style charger.
After seeing your videos I was thinking a small 3L supercharger feeding the turbo charger but I will have to do more research and some testing to see if it's viable
Anything is possible mate, would make for a very interesting project that's for sure.
Definitely interesting and if i find a viable supercharger, I can send you videos of the attempt if you like
@@ChristopherSchembri-y4y yeah absolutely mate I will be keen to see how you get on with it.
Spinning the charger at 20k probably won't give you twice the boost. The eton becomes less and less efficient once the rpm passes it's peak level. I wouldn't know to much about oil burners. But the fact that eton blowers aren't used don't used diesels from factory, kinda says all you need to know.
Was interesting to watch though. And it was probably making better power off idle than the turbo ever would.
Yeah I tend to agree with you mate, 20k is way outside of the maximum operating range of the charger. It does have fantastic throttle response and torque off the line is better then the turbo but once it hits 1500rpm it's all over
@@HarpersShed Compound turbos maybe? 🤔
@@crissyb00 that would be very cool, I think I have seen one with compound turbo's somewhere
Twin charge? Cheers Graham
The thought did cross our mind but the plumbing side of it would be a pain in the but
@@HarpersShed but with making interesting video
Sorry late to the party step father n law passed. He was a cool guy. Bigger blower. Oh and if I don’t talk on fb I get in jail cause my inside thought come out.
Lol all Good mate and I'm sorry to hear about your step father passing my thoughts are with you
@@HarpersShed thanks mate
Put the supercharger on the boat
That would be a fun project 👍
Wow ! Very interesting good on you for compleating this experiment! The response was great tho ! I think compound supercharged + turbo would be mad ! HAHa ! G300 FROM 7-36PSI TO TAKE over! 🛻📹🤙😎
It would of been cool to do compound but the plumbing would of been a real shit of a job
