Gday everyone. This time we try and fit an Eton M90 supercharger to my Fathers ZD30 GU Nissan patrol. Why you as well nothing ventured nothing gained. Cheers and hop you enjoy the episode. Tim
F'k me Tim thats utterly bonkers mate (UK expression, mad, crazy awesome etc) you never disappoint.... ever That exhaust sound was both scary and awesome, Im not a tech head and can't help with tech info but with channel moral youre nailing it!!
Mate I love your channels! Thank you for making the videos. One comment, please enjoy every moment you can with your old man. You obviously have a really great relationship with him. Savior every second! Cheers to you and your Dad, mate!
Hey mate, Just want to stop in and say that i love the build, and we need a couple more exhaust clips haha, I'm going big gated turbo on my di zd30, and it'll be ready for the first startup soon
If I spin it faster it will indeed produce more air but you start to push the rotors past the point of there efficiency and that just creates heat. Unfortunately the only way forward if I wanted to keep with the charger would have been to get a physically large unit.
I put a 3" exhaust on my 200 series landcruiser from the turbos back, with no mufflers or anything - it sounded a bit like this... so loud every head would turn, no matter how lightly you used the throttle! I had to add a muffler to make it drivable in public! Why did the boost max out? Could it be belt slip? I would have assumed a supercharger would keep climbing in boost as the revs go up, but I have no experience with them.
Hi mate, yeah sometimes lowder isn't always better. We did have a small amount of belt slip but that's not the main issue. As the rpm of the engine goes up so does the rpm of the charger so in theory your correct in saying the boost should also climb how as the rpm increases so does the amount of air the engine needs. So it actually works that the more rpm the engine and charge spin the boost level actually stays the same. Hopefully that makes sense.
Tim, As you say the pulleys need to be redone somehow. I am thinking the bottom pulley being larger would work better; that way no mods are needed up the charger end so you don't lose the strength. Airflow with a different airbox and snorkel could make that other difference And yeh.... you need a damm good muffler!!
Thanks Jim, I have ordered a larger diameter round of alloy to remake the lower pulley after all the port work is done. Also hane a new triple pass baffled muffler to install so fingers crossed that shuts it up a bit. Not too stressed about the airbox yet as the pod filter is probably the less restrictive of almost anything I can make with a snorkel.
Great episode I really enjoyed and it made me smile 👍🏻 you say you wanted more boost right. I would think that having a larger lower pulley would make less boost. Are you hoping that the charger mods will increase air flow and that way you will be able to run a larger bottom pulley. I'm sure all will be explained in the next one 🙂 great to see you experimenting.
@@joelnagle2214 thanks mate. A larger bottom pulley will turn the top pulley faster for a given rpm so should make more boost. I'm hoping that removing the restrictions in the blower will allow it to move more air for a given rpm so hopefully increase the boost but again that's all guess work at this point.
Hi mate, however you got here I'm always happy for the support. Yep that's me and yeah still have the boat, it actually has its own channel now called Harper's boat shed if you're interested. Still plugging away at the repairs on the old girl and trying to find time to take it out every now and then. Cheers Tim
@@HarpersShed Hi Tim thanks for the reply, I thought it was the Boat dude with the shed part lol I had a mate put a supercharger on a V8 Ford same deal had too muck around with the pulleys too get it making enough PSI Hope you get it sorted, I will check back in, Nice Machine work Bro and welding, Tell me about finding time with Projects lol, Seems too get harder and harder Glad you're still got the boat she is a Classic Take care bro
The blower. Seems that there are too many variables. Engine configuration , flow, rpm. Etc so horses & hand grenades i.e. close enough. Diesels don't spin. Can it be leak tested?
@HarpersShed ok I tend to start typing mid sentence. You thought it would make more boost. But I don't see how it can be benchmarked i.e. this many lbs at this many rpm. There are to many parameters. If you were using a set up commonly used then yes but. Sorry Mr whomever. Guess I need to type slower for you.
