Dane: I wouldn't bother with a road car either, was just saying I've been curious about the concept is all.

You should be able to work out pretty quickly if you need one from your own experiences. How long does the car take to get to operating temp?

This is why I love you Richard :wub:

Just looked them up - cheap as chips. I can use a converter to make it work with 240v and save myself a whole bunch of cash. Radical are replacing my dry sump tank with the latest version as part of my deal, so I'll enquire with them about heaters. Their version is pretty expensive from the UK so not sure why that would be.

Ben: I just found this old thread and people were suggesting the same thing: http://www.skylinesaustralia.com/forums/topic/333790-faster-warm-up-for-a-dry-sumpd-engine-oil-tank-heaters/

I think the external heater will be easiest for me, so I'll do some looking into that.

Not sure yet mate, have never done it myself! :P

I'll find out soon enough though.

yeah for the cost of buying a dry sump tank with heater (around $200 AUD landed) I would do that and tax the heater off it. they are simple power and ground wire though you may need some kind of controller to cycle it on/off (not sure). most likely all you'd need to do is put a female plug on the two wires and mount it neatly somewhere on the body work. when you want to warm it up just have a 12V battery with the matching male plug on some wire and just plug the battery into the plug on the bodywork. let it run for whatever time is needed and you're done. weight would be bugger all (maybe 500gms max) and it would be easy to use. still not sure if it's [i[really[/i] needed or not though. but it certainly doesn't hurt things. I'd do it.

dane, that one I pictured is on ebay right now for $129 USD. could have it here for well under $200AUD. sell the tank for $100 AUD and you've got a heater sorted for $100.

so does this earn me a drive or what???? :)

Not sure if the elements on that one will be the right size, so I might hold off until I know for sure what size I require. But thanks!

All it 's going to take for a drive now is a wristie, but you're close! :3some:

If it's that cheap and that easy and gives you some peace of mind it can't be a bad thing. Reckon it's worth waiting to see if you even need it first or are you just that damn excited already :D

I think I'll wait to see if I definitely need it and see what their recommendation is, but sounds promising to me.

hey mang, I'd give you a wristie for fun, but for a drive i gonna stroke it up real nice... (/scarface reference).

yeah, tank size varies a bit, but there is only a few common sizes really. there is a bit of room in the band type ones too for accommodating a tank that is a bit larger or a bit smaller too.

you just need to ask radical what OD the dry sump tank is going to be and then find one that matches. should be a piece of cake.

Agreed, should be easy as pie. I'm loving this solution! I thought the warmer was a good idea but the cost and complexity was a bit of a downer, this should hopefully work out nicely. :cheers:

....... But of course the option is there to run it off the tow car or jump battery.

I was having a bit of a think about it today and Marlins idea has lots of merit. This is not really just about Radicals,,,it's more about someone running a dry sump. Really if you are running one it's getting towed to events isn't it.

So if you were to run a 12 volt heater system you could use the tow cars power whilst towing to heat the oil up,,,get to the track and bingo a tank full of warm oil.

Which leads me maybe to a stupid question which someone might be able to answer,,,I've always been worried about the initial start-up with a dry system,,,the engine has sat around for a long period and all the oil has drained down to the sump/hoses ect and now you start it up and the pump is pumping tons of air before delivering oil. Shouldn't the pump be primed somehow before actually starting???.

Cheers

Neil.

Maybe a one way valve is the answer,,,I don't know and yes I've seen pics on SAU of an electric primer pump. I'd like someone who actually runs a dry sump system to spill their guts and tell me whats right and whats wrong.

Think I'll be venturing out to Parramatta speedway and ask those 700hp V8 sideways lunatics guys about it.

Cheers

Neil.

Element heaters in the base of a tapered tank are far better than blanket heaters around the outside. Think about what happens to hot and cold oil.

Cold thick oil always goes to the bottom to be heated evenly till the viscosity is even. A blanket heats the tank and the heat has to radiate to the center through the oil. it does but they are less efficient in heating the oil evenly. I have tested both ways in a tank with no lid. There was some drastic temp differences when using a blunt and a 300mm round tank.

Primers are a good idea particularly when used as an emergency back up as well as a primer. When you wire them to a hob switch and the thing throws a belt the primer can help alot. It won't save an engine doing a million rpm at full noise but you do have a chance with them.

Most sprint car guys I know don't use them. They use a shut off from a hob switch when pressure drops below 20psi. ( they can't idle so pressure is never lower than 44psi usually)

If they sit around or have a fresh engine a drill on the pump is used to prime the system.

I used to drop the belt and use a 3/8 air ratchet with a special adaptor to turn the pulley ( don't drive it by the bolt head in the end of the shaft when the pump loads up with oil pressure the bolt will snap)

Even without valves a dry sump pump won't drain back to the tank when it sits around. They drain back into the sump on the scavenger lines but otherwise the system will remain majoritily primed. The only time I've re primed a system was when some idiot turned the pump backwards with a drill and pumped all the oil back to the tank. Or if the car has been sitting for more than a couple of months just to be safe.

Neil I'm now stocking BDG and morosso pumps too when your ready to get one.

With a GSXR motor to 2C specs, nova replacement pump in the water pump location.......dyno time only.....no problems with prime or drain back into the sump, after sitting for a few weeks. If you made the tank tall and skinny enough, you might get enough head to fill the sump, usual space and positioning limitations of the tank in one of these, it'd be highly unlikely IMHO.

Don't know what's in your cars - Busas I presume - Kevin Leggatt (sp), did develop the scavenge pump for the kawa 1100 original some years back...which might save a few shekels and wouldn't be much of an engineering challenge to adapt I suspect.

neil we never ran priming in the dry sump cars i've been involved with but it does have a heater and did have a low pressure shut off (has overide for starting). when starting the car there is a separate fuel/ign switch. you simply leave those off and crank the engine on the starter (so no fuel or ign happening). oil pressure comes up so fast it's not funny and on the starter the engine is only spinning at a few hundred rpm max (not 1500+ like it would be at cold idle if you just started it and let pressure rise) and of course no combustion is taking place. as the brad said oil doesn't really drain back through the pump and lines when shut off so that's not really a problem. I wouldn't bother with 1 way valves in those lines. just one more thing to add.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
