Finally, the new build!

The Comp Oil-less use a billet center section and turbine wheel. They machine the center section for triple ceramic ball bearings in a special grease that they developed. The center section is self contained, the oil inlet is plugged and uses water lines for the required cooling.

Do they require maintenance? If so how often? Or just point me in the right direction for learning.

Wondering the same!

Looks good so far!

 

[retfr8flyr]

No regular maintenance just an overhaul. I was told on normal street strip style driving that they would be good for about 35,000 then send them back to Comp and it would be about $300 to redo the center sections with new grease but it could be more if they needed other parts. I doubt if I will even put 35,000 miles on mine.

Man that thing looks good. They use a synthetic grease and the water cools it.

Earl nailed it. Service intervals is actualy longer with an oil cooled turbo. With the oil=less turbo there are no oil seals at all and the bearings just need inspected and greased/repacked after 3 years/36kmiles, which is amazing. My oil turbos needed serviced once a year. To quote comp, regreasing the catridge at regular intervals can extend the life of the ceramic bearings indefinetly.

Why are you on here when you should be driving yourself and the new turbo over here?

 

[JEWC_Motorsports]

Even im awake waiting for him to show up and get this thing installed.

 

[Greg Hazlett]

LOL! If you leave now you can make it in time for the dyno session tomorrow!

Question: why do these turbos both oil and water cooled self contained require service so often compared to stock turboed cars? I'm just curious.

Car will be a beast Jeremy.

 

[Greg Hazlett]

Getting closer! Hot side in on, just needs to be tightened.

New fuel line is run, needs to have the Fore fuel filter plumbed in.

New fluids purchased and waiting to go in tomorrow.

Lots of little stuff to do like connect the oil lines to the relo kit, connect the water lines to the turbo, set the shifter and put the center console back in, plug in 02 sensors, cold side piping, re-install the radiator/fan shroud....and be done by 1-1:30 to be on the road to the dyno....gulp!

Oem turbo setups have alot of engineering and designing in them, not going to get that with an aftermarket kit on a car that was never designed to have a turbo. 3v's are a bit of a challenge with our oil pump volume/pressure. With oem specs and 30-40psi of oil pressure you will get alot more life out of it, also most all oem turbo setups are water cooled, most aftermarket arent etc. I see 90 psi oil pressure on startup and 70-75 psi crusing, 80 psi wot etc. Just not good for a turbo setup where its oil fed. Its either too much pressure which blows past seals or not enough so it runs hotter etc which is bad for seals and bearings yadda yadda.

Thanks for the lesson. That makes sense.

 

[mikeyfitz]

Wow your hot side is soooo much higher.

 

[JeremyH]

Yeah I sacrificed piping size a little (2.5" to the turbo vice 3") to clear the upr k member better so we shall see how it does at my hp level. I never had ground clearance issues with my old setup (although im not part of the low club lol) but where they go over the k member and through the a-arm doesnt clear the support gusset on my upr k so I had to change it up. Zimmers setup goes over the rack and pinion so for super low guys it is will be a nicer option we may be adding to our new single kit. I will post up how it does, may just have to limit rpm a little up top if I have a little high back pressure but who knows, only one way to find out!

Glad you got that that V-band fixed. Things are progressing nicely.

Thanks Earl, yup its on there just gave us trouble for a bit.

Jeremy, did you make that bracket that mounts to the turbo housing? I am using the one that came with the kit but I can tell your's will hold better. If you didn't make it where did you get it from? I may make one for the car this weekend. We'll see.

 

[Greg Hazlett]

I am 99% sure he said that one came from Zimmer's and yes, that mother*&**()^%&^*( is beefy! 3 mounting points ensure that thing is going NOWHERE!!!!
