i dont know the configurationof the gas turbine but if the fan take the air from
inside instade ooutside mite get warm seam to be ridicule but who now

Funny but i've run mine for half an hour and i can keep my hand on the resorvoir
quite easily maybe 120deg F . I've put an oil cooler on but havent bothered
hooking a fan to it yet , i guess if i were to run for a longer period of time
it might be an issue but i run out of fuel before the oil gets too hot and i
don't like to fill the tank with it running . how long do we play with our jets
before it is shutdown time anyways ?

one of the reasons that a tractor has little trouble with any oil is that
the volume of oil is considerable with large area and small porosity oil
filters and large cooling capacity. these little gas turbines have an oil
capacity of maybe 2 gallons? this small total volume heats very quickly and
very likely exceeds 180 degrees F. non-synthetic oil starts to carbonize at
160 dgrees. this is why it turns black. synthetic oils have various flash
points of 220 to 520 degrees F. the higher the flash point, the more
durable the oil. performance specs for good oils are available on-line from
the manfacturors. thrust bearings and especially babbit types should
maintain oil drain temps below 180 F. in order to maintain bearing
integrity.

tractors and combines with good results . We get many thousands of hours of
use out of these engines without any problems and the turbo is usually the
last thing to worry about . the oil isn't that expensive compared to
synthetic and it's alot thicker than 0w30 .

a 15W-50 oil. The first indicates how thick the oil would be at winter
temperatures, the oil behaving as if it had a viscosity of "15" and the
second number tells you how thick the oil would be at operating temperatures
if it were a "50" oil.

bike and kart , a little harder getting spooled up , and a little more of a
wait to get the lube warmed so it can flow thru the finer passageways in the
thrust bearing and provide the correct bearing support/dampering , but
closer to the correct lube for our turbos than the very thin lubes like 0-30
which if the ambiant conditions dictate, is reasonable to use , but for most
of us in warmer climates "ordinary" weight lubes are a better compromise .

my bikes TV84 , the TV84 had 3 "pads" taking the thrust , each ~5mm wide by
10mm long for a total of ~150 sq mms , the TL92 has 6 "pads" 7mm X 10mm for
a total of ~420 sq mms , on a square millimetres of thrust surface per
square inch of compressor rear wall (thats producing the thrust pressure
loads), the TL92 has just on TWICE the ratio of the "fragile" TV84's thrust
bearing , any wonder I wrecked a few of them , the guys at the turbo
overhaul shop had told me they had problems with the TV84 at high boost
levels on their racing trucks , so even with 90psi oil pressure that fragile
thrust bearing was marginal .

questions : I think 0w30 might be a little thin but am using it myself it

is it pulley driven, could put a smaller pulley on the pump . I am using a
factory gasket for the flange they are made to take the heat . I had noticed
on your hot start vid that it looked like the engine was just about to go to
runaway speed then you got it shut off good thing you had the leaf blower

reason i ask this is that if you don't get instant ignition and have the
fuel on it will run out of the flame tube and pool inside the outer housing
and then when you finally get it started the blast of air from the comp will
lift all that fuel into the flame tube and you have an over speed situation

so i changed the oil and now the max pressure the pump will put out (cold) is 60
psi compared to 80-90 with the 0w oil... so basically if i get it right the
pressure should go up a little when warming then it will remain enough thick to
allow the pump to push it at a decent psi... right?  sorry for the stupid
question i'm tired lol

Hi Eddy

As I mentioned in an earlier email , having twin/split inlet on the turb scroll
reduces efficiency .

If you look at the Turbine Flow "map" in the Link http://www.turbobyg
arrett.com/ turbobygarrett/ catelog/Turbocha rgers/GT45/ GT4508R.htm the
Corrected Flow  ranges between ~38 lbs/min and 47 lbs/min at a 2:1 pressure
ratio   depending on the scroll A/R used , from the 1.01 up to the 1.44 A/R

Assuming  you'd be running at a PR of ~3.5 :! ( ~37 psi)   and 90 lbs/min at 76%
effic   and with a pressure ratio of ~2:1 across the turbine stage  with a TIT
of 1500 F  and nil losses across the flametube , you'd have a turbine inlet
corrected flow of ~50 lbs/min , this is slightly higher than the corrected flow 
able to be processed by the largest scroll A/R  the 1.44 A/R , you'd either have
to reduce the mass flow by a bit or reduce the temperature ,  alternately , an
increase in rpm and pressure ratio could also bring supply and availability to
process , back into balance .

You'll certainly need to have the GT45 turbos equiped with the 1.44 A/R turbine
scrolls .

Cheers
John

Funny but i've run mine for half an hour and i can keep my hand on the resorvoir
quite easily maybe 120deg F . I've put an oil cooler on but havent bothered
hooking a fan to it yet , i guess if i were to run for a longer period of time
it might be an issue but i run out of fuel before the oil gets too hot and i
don't like to fill the tank with it running . how long do we play with our jets
before it is shutdown time anyways ?

one of the reasons that a tractor has little trouble with any oil is that
the volume of oil is considerable with large area and small porosity oil
filters and large cooling capacity. these little gas turbines have an oil
capacity of maybe 2 gallons? this small total volume heats very quickly and
very likely exceeds 180 degrees F. non-synthetic oil starts to carbonize at
160 dgrees. this is why it turns black. synthetic oils have various flash
points of 220 to 520 degrees F. the higher the flash point, the more
durable the oil. performance specs for good oils are available on-line from
the manfacturors. thrust bearings and especially babbit types should
maintain oil drain temps below 180 F. in order to maintain bearing
integrity.

tractors and combines with good results . We get many thousands of hours of
use out of these engines without any problems and the turbo is usually the
last thing to worry about . the oil isn't that expensive compared to
synthetic and it's alot thicker than 0w30 .

a 15W-50 oil. The first indicates how thick the oil would be at winter

if it were a "50" oil.

bike and kart , a little harder getting spooled up , and a little more of a
wait to get the lube warmed so it can flow thru the finer passageways in the
thrust bearing and provide the correct bearing support/dampering , but
closer to the correct lube for our turbos than the very thin lubes like 0-30
which if the ambiant conditions dictate, is reasonable to use , but for most
of us in warmer climates "ordinary" weight lubes are a better compromise .

, my next engine ( 10/94 BB) is going to have "brass bush" bearings and a
standard set of "bits" on the shaft to cut down the amount of work required

my bikes TV84 , the TV84 had 3 "pads" taking the thrust , each ~5mm wide by
10mm long for a total of ~150 sq mms , the TL92 has 6 "pads" 7mm X 10mm for
a total of ~420 sq mms , on a square millimetres of thrust surface per
square inch of compressor rear wall (thats producing the thrust pressure
loads), the TL92 has just on TWICE the ratio of the "fragile" TV84's thrust
bearing , any wonder I wrecked a few of them , the guys at the turbo
overhaul shop had told me they had problems with the TV84 at high boost
levels on their racing trucks , so even with 90psi oil pressure that fragile
thrust bearing was marginal .

are there nice turbo for a project ?

are they big enough ??pounds?  you told me there diferent turbine scroll what is
better small or large? i make sure to have the same numbers thank a lot for your
advice and the time you take to give it to me, i do aprreciate

Hi Eddy

Which one of the GT45 family http://www.turbobyg arrett.com/ turbobygarrett/
catelog/Turbocha rgers/GT45/ GT4508R.htm have you got , depending on the turbine
scroll A/R being used  you'll have different flow/performance .

Hi,

Contact;

All Custom Gasket & Materials Ltd.
355 Watline Avenue, Mississauga
Ontario, Canada
L4Z 1P3

Phone: 905-507-4580

They carry everything including flexible graphite.

See if they will sell direct or if they have dealers in Canada.

FYI all I did was Google -graphite gasket in canada-.

Good luck,

Roy

one of the reasons that a tractor has little trouble with any oil is that
the volume of oil is considerable with large area and small porosity oil
filters and large cooling capacity.  these little gas turbines have an oil
capacity of maybe 2 gallons?  this small total volume heats very quickly and
very likely exceeds 180 degrees F.  non-synthetic oil starts to carbonize at
160 dgrees.  this is why it turns black.  synthetic oils have various flash
points of 220 to 520 degrees F.   the higher the flash point, the more
durable the oil.  performance specs for good oils are available on-line from
the manfacturors.  thrust bearings and especially babbit types should
maintain oil drain temps below 180 F. in order to maintain bearing
integrity.

Why don't you just try15w40 oil non synthetic we use this oil in our tractors
and combines with good results . We get many thousands of hours of use out of
these engines without any problems and the turbo is usually the last thing to
worry about . the oil isn't that expensive compared to synthetic and it's alot
thicker than 0w30 .

starting a little easier . Could you drive the pump a little faster ? is it
pulley driven, could put a smaller pulley on the pump . I am using a factory
gasket for the flange they are made to take the heat . I had noticed on your hot
start vid that it looked like the engine was just about to go to runaway speed
then you got it shut off good thing you had the leaf blower stuck in the intake
so it couldn't get that much air or it would of over speeded . Are you using a
drain valve on the C.C. at it's lowest point ? The reason i ask this is that if
you don't get instant ignition and have the fuel on it will run out of the flame
tube and pool inside the outer housing and then when you finally get it started
the blast of air from the comp will lift all that fuel into the flame tube and
you have an over speed situation and there isn't much you can doo about it
except run like hell .

Hi Eddy

On my kart with its direct drive using karting chain and sprockets  I used a 10
tooth freepower sprocket driving an 81 tooth on the axle , you might have larger
wheel and would require a bit more gearing so try the 10 tooth to an 86 tooth ,
or larger if you can get one ,  on the axle ,........... ......... ...with good
quality racing kart chain you should be able to spin the freepower out to
~20,000 rpm before encountering chain problems .

Cheers
John

Hi Eddy

Theres nothing wrong with ball bearing turbo for our use , the reputable turbo
manufacturers wouldn't put on the market a product that fails , they'd be out of
business very quickly .

A turbo like the GT4708R only spins to ~100, 000 rpm , but for our use somewhere
between 85-90,000 is going to provide best results , above those rpm the comp
efficiency starts to drop off too quickly making it pointless to run up at the
extra rpm , but it does provide a safety buffer in case of a bit of a runaway .

The GT6041 has "brass bush" bearings .

To choose the right turbo,  you first need to determine what you want to achieve
from the engine , then find a turbo that can do the job ,
.............................so what do you want to achieve ??

Cheers
John

   Hi Eddy

   Any of the Garrett GT turbos with a number ending in "R" have ball bearings
and will require less oil for lubrication than a "brass bush" bearing equiped
turbo of comparable size .

   The GT4508R has a bit of an undersized turbine wheel for its comp size , the
GT4708R with a 1.39 A?R scroll on the turb, # 769112-4 , is a better matching of
comp and turb flows .

Both numbers are indicators of viscosity at different temperatures. Take a
15W-50 oil. The first indicates how thick the oil would be at winter
temperatures, the oil behaving as if it had a viscosity of "15" and the second
number tells you how thick the oil would be at operating temperatures if it were
a "50" oil.

ok so what weight should i aim for? what is the main difference between *w-30
and *w-50? i know the first number is kinda the thickness... would some 10w-30
syntetic oil be engough?

Hi Jon

Yep , I'll go along with that , I used 15W-50 semi synthetic in both bike and
kart , a little harder getting spooled up , and a little more of a wait to get
the lube warmed  so it can flow thru the finer passageways in the thrust bearing
and provide the correct bearing support/dampering , but closer to the correct
lube for our turbos  than the very thin lubes  like 0-30  which if the ambiant
conditions dictate,  is reasonable to use , but for most of us in warmer
climates  "ordinary" weight lubes  are a better compromise .

On a side note ..........I just received an overhaul kit for a TL92 ,  my next
engine ( 10/94 BB)  is going to have "brass bush" bearings and a standard set of
"bits" on the shaft to cut down the amount of work required ,
..............anyway , the thrust bearing is HUGE  compared to the one in my
bikes TV84  , the TV84 had 3 "pads" taking the thrust , each ~5mm wide by 10mm
long  for a total of ~150 sq mms , the TL92 has 6 "pads"  7mm X 10mm  for a
total of ~420 sq mms ,  on a square millimetres of thrust surface per square
inch of compressor rear wall (thats producing the thrust pressure loads), the
TL92 has just on TWICE the  ratio of the "fragile" TV84's thrust bearing , any
wonder I wrecked a few of them , the guys at the turbo overhaul shop  had told
me they had problems with the TV84 at high boost levels on their racing trucks ,
so even with 90psi oil pressure  that fragile thrust bearing was marginal .

Cheers

   hi,i used to use 0w30 oil but now use 15w60 oil,really not that bad spooling
up at all. it is quite expensive through!!i use it because the place i got my
turbo "freshened" recommend it.the upside is the ability to maintain ol pressure
at reduced oil flows.
   worth giving a thicker oil a try it seems :-)

LOL now i know what 25psi of boost in a 4" pipe feels like lol the thing is my

wraped some duct tape around the air inlet to enlarge it... lol not a good idea
it blew righ of... going to make a steel enlarger tomorrow at work with the CNC

Hi Eddy

On my kart with its direct drive using karting chain and sprockets  I used a 10
tooth freepower sprocket driving an 81 tooth on the axle , you might have larger
wheel and would require a bit more gearing so try the 10 tooth to an 86 tooth ,
or larger if you can get one ,  on the axle ,.......................with good
quality racing kart chain you should be able to spin the freepower out to
~20,000 rpm before encountering chain problems .

Cheers
John

Hi Eddy

Any of the Garrett GT turbos with a number ending in "R"   have ball bearings
and will require less oil  for lubrication  than a "brass bush" bearing equiped
turbo of comparable size .

The GT4508R has a bit of an undersized turbine wheel  for its comp size ,  the
GT4708R  with a 1.39 A?R scroll on the turb,   # 769112-4 ,  is a better
matching of comp and turb flows .

Cheers
John

thanks all!!! unfortunately i cant order from mc master since i'm in canada...
heh! i'll give the exhaust paste a try i guess. and ok i'll look into that kind
of oil!

many thanks for the answers!

hi,i used to use 0w30 oil but now use 15w60 oil,really not that bad spooling up
at all. it is quite expensive through!!i use it because the place i got my turbo
"freshened" recommend it.the upside is the ability to maintain ol pressure at
reduced oil flows.
worth giving a thicker oil a try it seems :-)

flange they are made to take the heat . I had noticed on your hot start vid that
it looked like the engine was just about to go to runaway speed then you got it
shut off good thing you had the leaf blower stuck in the intake so it couldn't
get that much air or it would of over speeded . Are you using a drain valve on
the C.C. at it's lowest point ? The reason i ask this is that if you don't get
instant ignition and have the fuel on it will run out of the flame tube and pool
inside the outer housing and then when you finally get it started the blast of
air from the comp will lift all that fuel into the flame tube and you have an
over speed situation and there isn't much you can doo about it except run like

Until he wrapped the coil the only thermal transfer area that he had was
conduction via the line contact of the helix of the coil. Considerable length,
but not much width. Wrapping it added convection to the process. Submersion
would be better, one less transfer involved (heat direct to the fuel tube vs. to
the tank wall to the fuel tube).

We proved to ourselves that it doesn't take much to back up the oil into the
turbo's drain. Not saying that it can't be done, but to my thinking it isn't
worth the effort.

if you want to warm your fuel and cool the oil at the same time here is a
creative and simple way to do it plus it take no more space that your already
have to build your project

I think you could build a heat exchanger that wouldn't restrict the flow too
much on the drain. That commercial one might be too much restriction. I think if
you were to setup some type of large diameter tube with the fuel line running
inside it so that the oil flowed over the fuel line returning to the tank that
wouldn't be too restrictive if you allow enough clearance. I still think the
simplest and most effective is a coil in the oil tank if it's doable on a
particular setup's tank.

the FT supported by the end plate, but with an air gap between the FT proper and

reduce sooting and consumption through better atomization. We now experience
occasional FT wall wetting, which introduces far less desirable behavior. More
acute spray angle nozzles are on order, but have not yet arrived.
