Thread: turbo fitted and running

Looks good - you won't be disappointed. What boost pressure will it go up to.......Brian

its hitting 10psi at the moment and this is the waste gate actuator opening pressure, I am not sure if I should go more most of you guys are running higher boost pressures but are down south in the cooler climates i think.

I am currently running 13-15psi and there is a noticeable difference from 10psi but I have this on a new motor. I have only done 8K on this motor. The big thing is to watch the EGT's. Did you set it up yourself or get somene to do it. As you probably know a small fuel increase is needed when you increase the boost....Brian

Your turbo looks like it is a water cooled version if that's a bung on each side of the barrel I can see.

yep I fitted it myself and yes it is water cooled but as you said has been blocked off, this is how it comes from turbo glide. I am still below the max egt I think I am only just hitting the 600 mark and I allready hitting 10 psi no worries, I am thinking of going to 12 psi. how big is your dump pipe of the turbo. So you noticed more power from 10 to was it 15 you have.

Great job - looks very tidy!

Is that your EGT coming out the bottom of the turbine (where the dump pipe flange bolts on?). If so, you are measuring EGT after the turbo - and 600oC is too high. Measuring before the turbo is preferable.

I have a 3" dump pipe and 3" mandsfrel bent system. Running 11psi at the moment, but will be turning it up when I add the intercooler.

Where was the alt sourced from?

I would recommend you hook up the water cooling - it keeps the cartride or barrel temp down and this will prolong the life of the turbo. It also virtually eliminated the chance of the oil vapourising in the barrel and causing bearings running dry and eventual failure. This is a possibility after a long drive when everything is hot (engine oil will reach 100 -115 degrees) and the oil doesn't cool down enough before you shut it down. The water cooling assists enormously at this crucial time. Have a look at the cooling setup on the 6bys. Easy enough to do and the thermostat cover with the turbo water fitting will fit straight onto your thermo housing. On the other side you can either acquire a 6by water pump (which has the water inlet fitting for the turbo) or modify your pump with a small nipple for the water tube. If you have a look at a 6by water pump you will see what I mean. My setup has both water cooling and an oil cooler (transmission type) in the oil feed line. Thats after it has been through the engine oil cooler. I still let it idle for a couple of mins after a long run and make sure the EGT's are below 200 before shutting it down. Mike Vine (the bloke in Brisbane who fitted mine reckons with the oil cooler and water cooling you can shut it down instanly after long hard driving) but I wouldnt. (Mine has done a lot of K's on 2 motors and is still in good condition so I guess it has paid off.)
You didnt say under what conditions you are reaching 600 degrees. This is ok for a long hard pull on a hill but you dont want to sustain this sort of temp for long. On the flat doing 100 your temps should be around 250-350, a little bit higher with a headwind or big load. My setup is 2 1/2 pipe all the way from turbo to end of exhaust pipe and it is important to have a flexible piece welded in so stresses are not put on the turbo when the motor flexes under load. 13-15 psi definitely increased the power noticeably from 10 psi but as said it is very important to watch those EGT's. Increase in boost usually requires an increase in fuel (lean fuel burns HOT). What did the motor came out of - it looks like a truck motor by the rocker cover. What age,how many K's etc, and did you fit the turbo pressure plate. Hope this helps. I get up to Townsville every so often, have to catch up one day......Brian
