Busa Oil Pressure
« on: July 06, 2011, 07:26:35 PM »
After spinning # 1 or 2 big end on my second gen 1 motor  thumb down
Yep I know they are known for this problem and one solution is to fit a grooved gen 2 crank
Thought would ask this question here as some of you guys are running busa torbo's in Ya rides
Yep I understand its a can O worms
Opinions are apreciated

Oil Pressure Gauges ?
Do any of you use them ?
What type/Brand is recomended by guys that are using to purchase
As Busa is know for low oil pressure at idle any how, can you see if there is a problem arising

What oil  ff: are others using and how often are you changing it ?

Do you guys have engine problems and not say anything or is it just me ?
Dont see Busa's bikes  in a race where they are held at 8 tho+ rpm for the duration
I didnt get much milage outa this second motor at all  drowning so looking for answers as stuffing them up aint an option I can continue

Mobil 1 full synthetic ,the one "made for" air cooled bike engines,change after every dune trip, KEEP the stock pan. I see super bikes at redline all the time on road courses. They handle it fine. Honestly I've never really heard of any real bearing issues.

BTW,IMO ,your issue is an oil starvation issue. You ARE using an oil cooler?

No gauge here..
I thought about one for this build, but opted to trust the little red light in the dash like all the turbo bike riders out there  ;D
So far so good. If I bought one it would be an Autometer, that's all I will use. I do run (and highly recommend )the HV oil pump gear in the case.. http://secure.mycart.net/catalogs/catalog.asp?prodid=791571&showprevnext=1 Small piece of mind because of the low idle pressures like you said.

I havent heard of any bearing issues myself either.  ??? My motor is a 2000 that I put 70k miles on before turboing and installing in the car. I refreshed her this winter and it was spotless inside. Every measurement was still within book specs and it has had a hard life!  ;D Countless blasts at the dragstrip, and a few hundred all day runs at 7-9000 rpm in the hills of Iowa. Mobil 1 Synthetic her entire life. This weekend was about a couple full throttle blasts down the highway uh, private blacktop?  ;) giving rides. All good!

Listen to Master! Gotta have that cooler on there!

Yes oil cooler
the starvation issue is well documented in gen1, Reasearch up busa oil pressure on the net
#1 and 2 crank are serviced by the same oil Gallery 3 ad 4 have their own

High volume oil pump gear have conflicting info reagrding them also
Was going to fit to this motor but after talking to a turbo drag bike decided against it
Here is his take on it

Quote
I log about 13 channels of data on mine
And logging oil pressure is one of them.what
I found was running a high volume oil
Pump gear is worse not better,what it does
Is make the oil pressure relief valve Bounce bounce
Dramatically going ftom 120psi down to 60psi
At top revs.with a stock oil pump gear its
Far more stable.secondly loading and unloading
The motor also greatly affects oil pressure which
Can cause the bearings to grab.

Some turbo Busa guys fit a pressurised bellows to
The oil system so it replaces a drop in oil
Pressure when it wheelspins or loses oil Pressure for whatever reason

Master whats the reasoning behind using Oil for a air cooled engine ?
Also what grade are you recomending ?

Look up Mobil 1 and see. Mobil makes one now that they say is "formulated for air cooled engines". Full Synthetic and supposedly higher temp rating. ANY Mobil1 full syn is good tho.  Personally I agree there is no need for a high VOLUME pump. Higher PRESSURE could be a good thing tho. . Added VOLUME is only needed if the bearings and other clearances are too loose but if that's the case fix the problem and leave the bandaids at home. I don't feel either is necessary.

Outstanding thermal and oxidation stability   

    Helps protect fluid film at operating temperatures ranging from mild to severe, minimizing deposit formation especially at the high operating temperatures found in air-cooled engines.

Does the Busa use a swinging oil pickup tube?

 Had always thought the up/down hills from a buggy might cause lack of oil pickup at times.  But these bike on the street see a lot more rear wheel only time than a buggy.  If I had smoked 2 motors and I even suspected it was oil, I'd put oil pressure gauge on my next motor, and brand motor.

No the busa does not have a swinging PU. It has a boat keel pan that IMO does a good job of keeping the oil around the pickup at all times but for a VERY STEEP dune face. I don't enjoy just sitting there so even that's a moot point IMO. Some of you know already that I am not in favor of a "high volume" flat bottom pan with or without an aftermarket swinging oil pickup. But If you feel you must use a flat pan to lower the motor in the frame USE a swinging pu with it.
