Water injection

[HollywoodYearwood]

Im sure this topic has been beaten to death in the past. Just wondering if theres any advantage to it on a N/A gas engine. Was thinking of trying it on my M John Deere. It has high compression and turns pretty high RPMS. And i have a dyno to put it on for tuning it.

Thanks

Typically water injection is/was used to prevent detonation on boosted engines. It was used on aircraft engines during the war and more recently Oldsmobile used it on the 215-CID turbo charged V8 F85 Cutlass, I am sure everyone remembers those.... Water injection will also prevent detonation on NA engines allowing the use of higher compression or advance timing. I am not aware of significant power increases from the water itself however, by allowing higher compression and or more optimum timing one can obtain increased power. Note, simply enriching the fuel mixture also tends to prevent detonation however, not to the extent as water injection.

 

[HollywoodYearwood]

That clarifies alot. My father owns his own auto repair shop, he has some horor stories of those ol' cutlass'. I dont have a problem with detonation. I have 125 cranking comp. and im running 116 octane fuel. And its dyno tuned. so i know i have the timing and fuel right on. I guess my only option for more HP is a more expencive alternative. Turbo maybe??

Thanks for the knowledge

Hollywood, "Turbo Maybe??" you say? Do you really want to run with the turbo boys? What are you thinking?

I have looked at that motor a little, I believe it is a 4 X4 or a 100 cu in. You are right they turn pretty fast. maybe turn 2600 legal. A WC Allis is also a 4X4 engine. There is a lot of 430 cu in Allis out there. and a friend of mine is working on a 500 plus one. Sooo a 250 in Deere is possible. Then cut your cam up and make the exhaust ports the intake and the intake the exhaust. Sooo you could have a 100 hp M or MT. It would be easier and cheaper than a Allis, and you can carry the block don't need a hoist. LOL Vic.

 

[HollywoodYearwood]

You are correct. mine is 4.125x4 now which makes it like 103 cu in now. Massive i know! mine makes 30 Hp now with gobs of torque. It has twisted the axle shafts in the diff. once already so i dnt know how it would hold up to 100 hp. One of these days its probably gonna just fall apart on the track, ive been pulling it since i was 7 and im 18 now, and its been run hard the whole time. My father and i bought a 40 JD and built the motor in it, broke it in, then spent sat. morning swapping the engine into my M and went pulling that evening, surprised everyone when we showed up with a mean motor! Its deff. one of the best sounding lil tractors you will ever here, kinda resembles a 435 with the detroit when it turns up high rpms!!!

 

[HollywoodYearwood]

I pull 3000-4000 everywhere and sometimes 4500 and 5000. Half the pulls we attend i am forced to pull in the super because i have dual exhaust, an electric fuel pump, and top cut tires. So might as well have a super tractor!!! and to nobody around here has a turbo on a 2cyl JD!

 

[VicS]

Yes I have a 435 I have twisted the bull pinion shafts or rather knocked 2 teeth off. also spit the spider gears out. It happened when one wheel hit a soft spot and the tractor turned almost 90 deg to the left then caught. If you aren't breaking parts you aren't trying hard enough. Vic

 

[HollywoodYearwood]

I broke the front end out from under it when the front slammed down with 600 on the front. So I wrote on the bracket " if it breaks again we'll fix it"

 

[jd plowboy]

so all the talk in sc was true when they were saying yall was running top cut tires in the stock classes.

 

[ricky c]

he dont want no turbo boys in his class

 

[HollywoodYearwood]

Hey ricky, I got a 800 hp 2130 JD waiting on you! Haha

 

[HollywoodYearwood]

Anybody that knows a little about tires can look and tell they are top cut. It was no secret, we never were trying to hide it.

But yes we were, and still do in ga. run top cuts in the antique or stock class. We were thinking of coming to the pull in pelion sc in oct. But I don't even meet regulations to pull in the open clas, let alone div. 2 or 3

A mild tractor with top cuts isn't gonna out pull a wild tractor with road worn tires. Besides no point in spending your life savings on a motor then griping over not wanting to spend half a sat. making your tires where they will hook up the motor you just built. Tractor pulling is simple, the person with the most cash, knowledge, and time will win.

 

[jd plowboy]

not all the time. a perfect example is enforcing the rules you have. the purple moline that i was winning all the time with i sold and went to indiana. he had to cut the rpms on it and it doesnt pull like it did here according to the pull results i have seen cause of the pms. rules will break some of the cheating if enforced. i dont have a super tractor now but i pull my 460 in super cause i have a homemade frontend and running higher rpms.

 

[HollywoodYearwood]

I've watched your tractor pull. I see nothing wrong with it where you shouldn't pull in the antique. If people want stock, the that should be it, stock, not u can stroke it but u cnt twist the rpms up high on it. We are pulling stock classes like nascar is running stock cars, I mean really? I understand that there have to be rules, and they need to be inforced. But in my dad's v8 classes all the rules say max rpm 5000. The cam in his motor is designed for 4500-7500 rpms and he has a 7000 limiter in it which it always hits. so if your moline is like his v8 then cutting rpms will kill it.

I pulled my lil m then my b, for many years coming in second or lower. I would win every now and then cause of a mistake on the competitions behalf. I got my G and it was pitiful, would choke down in the 5500. But my father and I spent a lot of time at night and on the weekends to build it into what it is now. That took a good sum of money which accounted for many birthday presents and christmas presents, Glenn Neal even gave me the head studs in my motor to me as high school graduation presents! My father and I work together during the day, and we workd on our tractors and night, and on the weekends my family goes pulling. I have a niece who is 5 and a nephew that is 6, and both are dying to start pulling. My nephew helps us load up every Friday before the pulls, and its really great bonding time for all of us as a family. I see so many people come to the pulls by thereself and the start whinning and gripping over stuff. Mostly because of a lack of effort toward working on there tractor. I'm just thankful I have a family that supports pulling and that we can do it and be successful. You would think showing up at a pull with 6 john deeres that people would come greet you and be glad to have some other competion, instead you get bagered because you came. Just doesn't make for a good pulling day when people cnt just get along.

a 100hp m/mt? yeah ok!

 

[glenndeere]

Go get "em Hollywood. Saw the gleam in your eye when you pulled the A before the bad G was powered up. Knew the G would be one bad animal in due time. The rest is just jealous now. I think it will take on all challengers.

 

[jd plowboy]

no body would get in the classes with the purple moline when i had it.

 

[ricky c]

bringing it to rays

 

[HollywoodYearwood]

It opened up a know new meaning to the term money pit! haha Places like Longneedle closing the doors is causing the pulling world to become a more scarce thing to come by. And JD Plowboy, your pulling with the SC crowd. If it looks stock then it is. Purple just stands out to bad lol!

 

[VicS]

I went to boonville In. last night the Purple MM was there, He just never had the balance right, almost had it but not quite. had plenty of power. But what can I say nether did I. Tried the right side because the left had a wet spot looked like you could never get thru it. The Fair Queen pulling for the first time in her life on a real good 44 Massey went to the left right thru the mud hugging the left boundary and out the gate! When it is your time it's your time! I tried it in the next class and came up one ft short for second. Not bad for me. The purple MM never got thru the mud. in the next class. LOL Vic

 

[jd plowboy]

the purple moline will never pull like it did when i had it. i was running it at 2500rpms and it would pull 8.3 mph in 3rd gear. when LW built that engine it dynoed at 170hp on his stingy dyno as people call it. before the guy bought it he talked on my phone with LW about the tractor. he said that he could only run it at 1700 rpms and that really cut the hp on that tractor but he still wanted it. it is only 570ci with no stroke and built that hp.also he is pulling it to light cause he cant hold the front down with the torque it has. i ran 400 on the front in 5500 and 600 on the front in 6000lb classes and sometimes more to keep it down. it got to the point that at some pulls i had no one that would get in the class with me. if he could turn it back to 2500 rpms and get in the 6000lb class in 3rd gear it would be mean but i looked at the results at some of the pulls he has been and he is pulling it too light. i also see where he changed it up some and i dont know if he has done anything to the engine but i was told not to change anything on it and he was told that too from LW.it was set up by the best moline man around here. also i found out that the V CUTS on it down here didnt like a soft track.

 

[VicS]

I never paid that close attention to it but I doubt he is just turning it 1700 I would say 2000. But it is a 4 mph class and 1700 in second might be as fast as he can go. There is hardly anyone to pull against if you go 8 of 12 mph.

 

[friday nite farmer]

turbo on my 730D ran 140 hp with other small mods pulled 7500 9000 lb classes till i got tired of all the crying
