I'd like to turbo this beast. It has a 15hp honda clone. Any ideas if it can be done reliably with something small like a VW K03(anything smaller out there?) I may need some more power in mine. Obviously there would be no management possible with this, and how would one lube the turbo? And if you're wondering what I'm running this on, well here it is:



That was an old pic. The transmission failed so I decided to convert to a hydrostatic setup hence why I may need more power. Here is a more recent pic and I'll have some better ones on the way soon. Yes its a scratch build 40% M4A2

Awesome, what about a GT17 with water cooling and oil suppled from sumps.

Or an Aerocharger turbos those are suppose to self contained. 

[highroller54]

Oh fuck ya, more pics of tank please!!!!

Smart car turbos are small as fuck but you would need to cut off the built in mani and weld a flange on. V band or something.

That's the same thing I was thinking. Step dad has one sitting on the shelf in his garage that's a new take off that I could probably get him to sell for cheap. Draw through carb and some race gas and a sump setup for the oil and away you go.

Only if you certify me as an OG, lol...and I know you know who I am  ...I'll post more in another thread as progress continues. I'd like to leave this thread open for turbocharging discussion for this beast! I'm also gonna be starting a college program very soon so that'll put me out of commission for about 10 months with only weekends to spare. I estimate it will be summer of 2015 once this thing is fully done with detail and final paint.

Use of German parts on an American tank huh? Interesting, I don't think the vets would appreciate that one! Hahaha. Fuck this gives me an idea! Plenty of whiny faggot fighter pilots and officers on base here with smart cars 
Another option would be a turbo off a Chevy sonic. We have an LTZ and the turbos are tiny in those things. But being a new car and the fact that most people buy the gutless 1.8 around here, they're very hard to come by second hand.

So a sump of some sort with an external reservoir would be enough for oiling you think? As for the management side do I really need to worry if only running 2-3 psi?

[92CXyD]

Sump would be the way to go

As for the fuel management, is the fuel pump manual?

If so does it have a port to reference outside pressure?

Need to figure out how to retard timing while in boost only or figure out a compromise to having base timing retard.

Talk to Dustin. I actually thought you had died lol. If it was up to me I would do it

[ratcityrex]

Russ I think it doesn't have a fuel pump. Think it'sit's gravity feed to the carb. Would have to do a draw through.

That case talk to Daspoop, he has experience in this, and there was a motorcycle project that had this.

First link; turbo would be good for this size engine.  They got ecu kits for small engines too.

Now you just need to figure out the 12 gauge turret!

[Xgenturbo]

Sweet thanks for the link. Yes there is a gravity drain from the fuel tank and in to the bowl and then the carb takes from there so no fuel pump. I was thinking something along the lines of a separate system so while under boost a pressure switch closes a circuit which makes an external injector open and a fuel pump pumps extra fuel from the tank in to the air intake post filter.

I do plan to run an alternator so I will have plenty of amps to run everything. Speaking of alternators, does anyone have a GM 1 wire they're willing to donate to the project?

As for the shotgun idea well it's sort of illegal in Canada to have a vehicle mounted firearm...But...if I have a high powered golf ball cannon nobody will give a fuck! And by powerful I mean a hybrid combustion capable of putting a golf ball through 3/4" ply at 50 yards+ 

[Xgenturbo]

Ok bitches so this is officially the tank thread now 

Here is the result from the progress over the last little while. Time to make it all work now. The rest of the week is going to be focused on finishing the hydraulics setup. Stay tuned.




Steel plate detail. Damn I'm good with Bondo!

[92CXyD]

Badest build ever, when boost is added. 

[jdmhatchracer94]

Fuck ya awsome

[92CXyD]

Here look in the Other section of this http://www.realhomemadeturbo.com/forum/index.php/topic,435.0.html

You get my vote for front page with build link, when this gets boosted.

I'm sure there may be other who would feel the same way. 

[Xgenturbo]

That would be awesome! But as said before, it'll be a while before it's at that point. Meanwhile I'm taking donations...no I don't want money! I'm looking for a free or super cheap GM 1 wire alternator and a K03 or smaller turbocharger. Going to school very soon so funds will be tight.

[highroller54]

I got fuck all or I would donate!

[Xgenturbo]

No worries bud! I just realized I have an old VW 1.9 Turbodiesel engine kicking around that was supposed to go in to my 4Runner but the project got scrapped when I bought my newish Tacoma. Guess what it has on it...Yep a K03 I'm assuming. I have no idea if it still works but its worth a shot. Still need the 1 wire alty tho.

Oh and look at what I found on the interweb. You'll have to go a few pages for the turbo build part of it.

Edit: The guy ended up going with a KP31 off a smart car because he couldn't spool the original eclipse/talon turbo enough. I'm thinking that maybe my engine is too powerful for that? He is running a 160CC Honda and my engine is a 420CC Clone. Should I stick with the K03 or try to find a KP31?

[turbohf]

I would try free first. 

[92CXyD]

I would try free first. 

+1 you can always switch later after you iron out the setup w/ free turbo. 

[Xgenturbo]

No such thing on this planet anymore...I proved that point today when trying to get some scrap pipe from a local place. I needed a foot of 2" shed 40 to build some engine mounts. They had a big chunk in their scrap bin that was 5' long. I asked if they could just cut a foot for me and they said no. I had to buy the whole fucking piece! Anyway $20 later and I have 4 feet left. Guess I'll use it over time. It sucks ass living in a small community way up north because things are very very hard to get, and very expensive when you get them. Even the bone yards out here suck major ass! This is why I'm accepting donations to this project as I'll never find things such as a smart car turbo. I may find a GM 1 wire but it'll cost me an arm and leg. The closest big city is a 3 hour drive.

...The closest big city is a 3 hour drive.

Where do you live?

[Xgenturbo]

A shit hole called Cold Lake, Alberta. Only reason I'm here is the money in gas and oil.

Here is one for you guys. I have a large DC motor and when I spin it with with a cordless drill I can get 5 volts and 17 amps out of it. I imagine with a small pulley running off an engine turning at 3000-3600rpm I can get quite a bit more. Would I be able to charge the lawn tractor battery with this?

how much power does your engine make stock?

[weirtech]

fuck yes!  can't wait to see what you come up with for the cockpit/turret!

[highroller54]

fuck can't wait to see you cock

Aaron!!!!

[Xgenturbo]

Engine makes 15hp and I think 18 ft lbs of torque at 3600rpm. So with a turbo maybe 20hp? If I turbo it which I rightfully should!

The turret will be made of fiberglass and house a cannon...I know that much LOL. Sorry I couldn't give you a better answer Aaron...I still have no idea where I'm going with it. Maybe it will shoot golf balls, maybe I will make my own resin cast projectiles. Who knows. All I know for certain is that it will be a metered combustion type with a breech load as I have no room for pneumatics and besides, they're weak sauce compared to a good propane or oxy acetelene combustion cannon. Been doing a lot of research on the spudgun forums though.

[weirtech]

my vote is for clay pigeons as a secondary weapon.  looks badass so far!

[DSharp]

I think you need to get your hands on the smallest turbo you can find.  rhb3, rhf3, probably a few about this size.... any bigger and you're wasting your time.
