Bender II blowing oil out the turbo still....any revelations

[Turbomania]

RX, I will try that thanks.

Spray, here is the deal. I actually bought Terry's R&D sled from him two years ago. It had 230 miles on it when I bought it, and it now has 1100 or so. I have had nothing but problems with this thing, which is not anyone’s fault but my own. I have 4 cats I play with and I do not pay enough attention to the one that counts. Two of my buddies bought the first two kits Terry sent out and had alot to do with turning up the boost. They talked to Terry everyday and he was quite helpful and I have his cell # and everything, but this oil issue he says is isolated, yet everyone I know but one person has it. When I bought the sled it had the tank in the trunk with the pump back there also. This worked great except it leaked out of the breather and you had to fill it every 250 miles or so (from my buddies experience) so I would really like to make this work. To say it is isolated I have to disagree. They both sold them and were tired of the headaches. I feel for Turbomania because when I first put the off of the engine oiler in mine I could barely make it 100 miles. My one buddy used the old tank as a catch and then sent it back to the motor and it helped, but if others are making it work I should be able to also. I will call you tomorrow.
thanks to everyone on here and hopefully I will gain interest in this thing again, but my firecats sure start and run very well.

Turbomania, where are you from???

It's a friends sled, I did the install and most of the tuning. We got one of the first few kits also, it's been a challange to say the least. I am going to talk him into throwing away those carbs and injecting it next year.
I live near Flint Michigan.

Man it must have been kind of a Hack job to start with, they should not be this hard to make run right.

Skydog GOOD LUCK!

Agreed

Silver Streak measured some jets. Here are the numbers:

110 .044-.045
105 .040-.041
100 .035-.036
80 .032-.033

We should all be using a 90 right now. I wonder if we should drop down to a 75 or 80?

 

[Mountaintech]

Ted mentioned that the manufacturer stipulated a .030" orifice but your #90 is not far off at about .034". I think what you guys have to start finding out is actual flow amounts ie. how much oil is exiting the turbo say at idle and perhaps at 8000rpm over a period of a minute. Then check and see what the pump will pull through the line in the same time. If you could compare this with someone who has a Bender that has no problems you may find a discrepancy.

 

[spray25]

Terry claims that the electric pump will take more than the engine can put out without a restrictor. I don't know if that is true or not.

I agree that .034 is not much more than the .030 however going from the 110 (.044) to a 90 (.034) made a BIG diference in oil consumption. I wonder if getting down to .030 just might make the diferrence. If nothing else it would probably help.

My current thinking is to go to a 75 or 80 and add a collection tank like MCX. I think the oil is collecting in the line and causing back pressure. MCX must be putting that tank in there for a reason.

Hell at this point I would try just about anything.

my buddy put his old tank back into the trunk as a collector and it helped, but I think I threw mine away. damn. I am worried about going any lower on the jet and not giving it enough, however, I am sure you could go quite low and still have plenty. pull the line off and still alot of oil coming out.

Yeah, I threw away my old tank too. I'd like one below the turbo though instead of behind it. It's good to know it helped him. How much did it help? Is he running the 90 restrictor?

 

[rxrider]

The MCX collector tank is underneat the turbo, it's a Mitsubishi 16T turbo on my sled. There are two hoses going from the turbo back to the engine, one line goes to a pump mounted on the engine magneto, the other goes into one of the thin oil return lines on top of the engine oil tank. MCX has a oil return pump kit that may fit. It may be possible to rebuild the oil feed and return system all together by installing MCX oil filter adapter and their oil return pump, just my ...2 cents

spray,
Can you email me the stuff you have on turing the turbo to pemling@chartermi.net please.
thanks

This is how I fixed my Oil problem.
1st. Make sure all your electrical connections to the oil pump is secured correctly and there is definatly no short or loss of power to the pump otherwise oil will go through your system when the pump stops working.
2nd. 90 jet in the feed oil line.
3rd. This I believe was huge. Your return line comes to a T at your oil tank, goes to your tank and back to your oil pump. get rid of the T. You need to drill a hole in your oil tank and put in a fitting in it that makes the return line go to your tank and then back from your tank to your oil pump.
I believe when ridding in the Mountains and your sled is elevated in the front or back (not level like flat Landers) the oil by passes the Tank completly and goes straight back to the oil pump.
After I did this I have had Zero oil problems!! My exhaust tip is a grey to light brown with Zero oil. Before this mod I had a oil problem that would cover my tunnel ext and make a mess, when stuck on a hill you better shut off the engine right away or you will fill your system with oil. The problem is completly solved now by using the 3 steps above.
I hope this helps, it solved my problems.
Another must mod to the Bender system is heat wrap the hole exaust & Turbo. This is huge for spool up and I gained boost, make sure you put some kind of protection over the heat tape in the tunnel where the track can hit it. I cut some exhaust pipe in half and hose clamped it over the Bender exhaust.

Moose, you no good bum! Where have you been hiding? Haven't seen you in a long time. Are you all healed up now? If yes then you better be here for the Presidents weekend ride!!

#3 is interesting to say the least. When you say the tee makes the oil go right back to the pump are you talking about the electric Bender pump or the OEM pump in the engine?

 

[RX-1 Moose]

Spray, how are you? I am mostly healed, went ridding 5 times already and feel like a %$#* FORGOT all the muscle you use when you ride.
It is the return line that goes back to the Bender pump I believe. It Tee's right at the oil tank & plugs into the top of the tank. What I did was plug the return from the Turbo to the top of the tank then welded a piece of aluminum to the front of the tank that makes the straightest line to the oil pump so you don't have any kinks in the line and threaded a fitting, I believe 1/4'' so you can slide the oil line over it & clamp it on. The reason for welding a aluminum piece on is the oil tank is to thin to drill at tap for the fitting you need for the oil line.
I am having absolutly zero problems now. I did rewire my system at the same time. If you have a bad connection and the oil pump stops working for even 1 second it will shove oil through your motor and out your exhaust. I could not find a problem but rewired it to the new surge, clean power adaptor Michael Klassen sent to me with a new gauage. ZERO problems now.
Wrapping the exhaust and Turbo is an easy trick to get rid of the little lag we have, I can literally shoot off a drift now with no hesitation and I gained boost running 17lbs at over 10,000ft where before the wrap at elevation I was running 13lbs to 14lbs and 15lbs at lower elevations. I turn down the boost now when on the trail. I also modified the rear of the sled and opened it all up and made a intake charge tube that looks like the exhaust with a K&N filter and prefilter on it. By wrapping the turbo and exhaust I eliminated steam issues and opening up the whole rear end allows the intake to cool a little bit more.
When I get home in about a week I will take some pic's and post them. I am very, very happy with the set up I have and you guy's are correct, we did seem to be the tuners for Bender out west, definatly was not a bolt on application. I just put good fuel in and ride now.

Spray,
Send me the info on the ride and I will see if I can make it. things are going pretty good now so I should be able to make it!

Thanks

Instead of welding an aluminum piece to it try drilling a hole and use a valve stem, chrome valve stem and take out the core. My buddy said he did it that way and it worked great for him, did not leak at all.
Sounds like an easy fix to me.
