350 turbo ?

Can a 350 handle any boost? Just a thought I don't know much about the engines. I do wish mine had more power sometimes.

Hi.
I have played with the same idea and will do it soon on one of my doner 350's

.1 Tinker alot with my 2 dodge diesel trucks and know it can be done to the little 350 if you use your head.Were talking adding maybe 6 to 8 hp MAX.A small streetbike turbo or small turbo off a compact tractor could be used in conjuction with a adjustable wastegate or blow off valve and boost gage.The biggest problem would be the exhaust manifold where the turbo actually bolts too.This could be fabricated by any high end race car shop.KOOKS racing would be my best bet.Problem is it would probably be around $1000 for that piece to be made (done right)I know because they have made several turbo exhaust manifolds for me $$$$$I'm sure there are other alternatives??Depending on the size of the turbo,I think 8-12 PSI of boost would keep the little 350 together.Compression is the killer with turbo powered ANYTHING.I have had turbo GS 1100 streetbike and turbo Mustang.Low compression kept these engine together.The higheer the compression,the lest boost you can safely run without completely emptying the bank for bulletproof components.This is why I dont't have my car and bikes anymore.I could have a brand new 650J dozer for the money that I have blown on toys.

hello, i have a friend thats gonna put a turbo on his 350B motor, deere did install turbos on those motors, just not on the 350s. i believe its the 2150 and 2350. i will check with him and find out for u guys. the parts for installing a turbo should bolt up without major modifications.

Hi

About the turbo idea? Wouldn´t it be both easier and maybe cheaper to install a compressor of some sort? That way you don´t have to get the exhaust manifold made up, only the pipes and hoses to do it.

Thanks for the tips guys. I was not aware deere put power adders on this motor. I don't know a lot about 350 engines is there only one model on these dozers thought out the years?
I agree a blower would be easyer to rig but I don't know where to find one the right size. I tihink I can get my hands on a crotchrocket or small sports car turbo. I do stainless pipe weldding so I might can do it. And a blower would put more stress on the crank.
I'm very interested in the deere parts for the 2150 2350 do yall have any idea how many pounds deere pumped them up to?

I would look for a turbo off of a VW jetta or somthing smaller, I think that should work

All the factory parts to install a turbo should be readily available used, new, or aftermarket. Given the huge volume of tractors, crawlers, stationary power plants, and other OEM's that used that basic engine, there are lots of choices.

Start looking at tractor wreckers .The engine was modified over the years but the big thing will be the lube and return line it has gained a few cubic inches but intake and exhaust manifolds are the same or darned close anyway the Deeres usually gave up smoking when turboed .My 350 D has a turbo and there is not much turbo lag to 1300.rpm and some good turbo boost at around 1500 plus right up.just a lot cleaner exhaust than the 350C that is all .But it is like putting a turbo on a push mower engine you can buy them but the boost may not be worth the bucks .Digitup,

how do the steering clutches take the extra power?
The 450 has more power and DISKS!

Were only talking 10-15 extra horsepower TOPS (closer to 10).I think they would be fine???

Post by **Lavoy** » Sun Dec 02, 2007 7:29 pm

At 10-15 HP, you are talking a 25%-40% increase, right at 450 power levels. I would almost guarantee at the power level, you will encounted some sort of drive train issues. At the very least, reduced life expectancy of everything behind the flywheel.

I think you will find the clutch packs on a 350D are the same size and quantity as the 450D packs should be no problem but if yours is a 350B-C-or D it should be OK There is a way to find out where the week spots are Put the turbo on and give it hell .You will only get a maximum of 10% boost in HP so around 4.5 HP- I took my old 450B one day and put it up against an old stone wall with the tracks across the rail road tracks hooked the blade into the wall and thought .This might not be the best idea !!!.I may just find a week link in the transmission or drive .But I gave it hell and proceeded to roll up the rails [corkscrew fashion ]under the dozer .It really is amazing what these old Deeres can take and come back for more Oh in case you were wondering we took the tracks up just after Knocking down and removing the building and Dad and the hired man just shook there heads in amazement when I did it .Digitup.

Lavoy,
Like I Said above,10 -15 hp would be an overstatement.Alot of people think that by putting a turbo on will add amazing HP figures.IT will,only if you add the appropriate amount of fuel.We all know that Diesels make more power by adding fuel.Digitup is correct in assuming a 5HP increase.Even at 10 I dont think there will be issues!!!!

Post by **Lavoy** » Mon Dec 03, 2007 7:02 am

Yeah, I know what you mean. Seems though like once the turbo is installed, too many guys look at the "smoke" screw, and figure what the hell, just a turn or two won't hurt.

If you are going to crank that smoke screw give her all she has got and get back to us on what you broke or twisted off !!A turbo only cleans up the emit ions of that little engine I think.But it sure adds some whistle at 2000 rpm around 1650 to 1700 it acts like it is workin its ass off but I think an natural aspired would do with in inches in a good push .There is a guy down south there some where that even makes turbos for Briggs and Stratton engines he advertises bolt on kits for Harleys .I should look him up I could use one on my Kabota tractor it needs some real boost it looses power after 1800 rpm with a 7 foot 6 inch snow blower on it and yes the little plastic cover fell off the throttle screw so I had to turn it a bit .Digitup.
