6610 New holland

Looking for anyone who has added a turbo to their 6610. Was wondering how it worked out? Heard of a lot of people say it isn't the wisest move but looking for actual first hand feedback.

Are you talking about a 6610 S with a genesis engine and vertical oil filter?
If so... you're probably going to end up with cracked pistons.
I haven't done it... and personally I wouldn't. The main differences in those engines are that the turbo engine has a heavier piston with keystone rings and a larger wrist pin... the crank is nitrided to harden it. The valves have a different grind angle to cope with the extra heat. The engine will require an oil cooler and probably a larger fan depending on what's installed. There's also probably be differences in the balancer weights to deal with the heavier pistons... so there's a lot of little differences in those engines between turbo and N/A.
I suppose if you were going to turbo what you have and turn it up 10% or in the range of 85 PTO hp then you're probably not going to see a problem... but if you've got visions of cranking it out to 120 on the PTO you're going to break stuff. Genesis engines are well known to crack pistons if you set them too hot...

If you're dealing with an older 6610 with a square 268 engine... you probably won't get any more snort from it without an injector change to start with. That one will probably live for a while at 100 hp provided you monitor exhaust temps and keep it under 1000 or so. I expect it will eventually wear it's rings down along with the piston skirts and wrist pins. In that generation of engine the wrist pins were splash lubed on the N/A models and pressure lubed on the turbo models and that also added to the cooling of the piston... so if you get too much fuel into it you might just melt a piston down...
The compression ratio is also LOWER on the turbo engine of that generation... so that might lead to some piston cracking if you get too hot on a N/A piston.

I would like to do that to my 6610 II also, but have not gotten around to it. I am aware of the cooling and compression differences between that and the 7610. I would not use it all the time, but would enjoy the peaking increase.

I have a 6410, it"s a "91, (same as 6610), we were short on HP when it had less then 2000 hrs on it,no money for a bigger one so the dealer put a turbo on.
It has 11000 hrs now, never touched the engine, it is using some oil,it runs a 1000 cu/ft TMR mixer so it has to work pretty hard.It"s a lot better on fuel to now.We did put a bigger rad in at the time.

Glad to hear. Was in the same situation didn't have the money for a larger tractor, and my 6610 couldn't quite handle my round baler or mower when I hit some of the bigger hills. Took it in and had it dynode, it was putting out 62 hp out the PTO which was a little low should have been closer to 70. Had it worked on and added a turbo and got it back at a 102 out the PTO.

Are you sure you want it @ 102 PTO ??
From 70 to 102 is almost 50% more......
Mine is @ 86 PTO, you better keep an eye on the temp

The mechanic installed two new gauges along with the other changes, oil pressure and temperature gauge. Will watch carefully. If it seems to overheat as I enter hay season it will be turned down a little. I am thinking that since before changes it handle my equipment most of the time at speed I was comfortable with that the times I need the extra horses will be intermittent and not cause to much added stress.

1st round of Hay in the barn and what a difference with the upgrade. Was able to handle 10ft mower conditioner in thick hay on hills at 6 mph. BR780 baler even less effect on the tractor. Was able to gain 2 gears with baler, with no overheating.

Update: Ok so it is several years since adding the turbo on the tractor, although I don't regret adding the horsepower, I felt that I was asking a little too much out of the tractor. I have since purchased a larger tractor to run my larger equipment. I like having the 6610 as a back up that can run all the equipment if necessary.
