The ratio of turns of input shalt to axle. 19 turns of input shalt turns the axle once.

I would guess so Get as tight exhaust housing you can. You may going under it at the end of the run. I spin a lot bigger turbo than that with 466.

I agree find a reputable engine builder and do it right the first time. It will the cheapest money you ever spend.

X2 on fire ringing. As far as gearing it would depend on what class you run, how heavy, and how much HP. When I run 6250 lbs. my high gear 19/1 is too slow, When I run 7500 lbs. its too fast.

I would put a gt42 on it if you want to make more than 500 hp. Very reasonable price and very tough turbo, easy to spin.

Ed, I don't want you to spend money on parts that are not the best and have to replace them with better parts. I hired one of the best pullers in pulling to build my motor and been very happy with how it runs. I am running north of 1200 HP. I would suggest getting custom pistons, re-ground cam, harden rods, and a very good 3X3 turbo. Spend your time, money correctly, and build it right the first time. It more fun running than wrenching on the tractor all the time. You can PM and me and I will let you know who built my engine. Good luck.

Water is easy buy a Simpson's valve, and pump and plumb it in. I don't want to burst your bubble, but you will need a lot more than 800 HP to compete in Pro-farm class. 1200 HP is more realistic if you want to be in top half of the class around here. Find a builder that you trust and talk to him.

Can you run water injection?

If the class allows I would build a 466. Many more parts available. What ever you do, do it right the first time. If you think that you only want a 500 HP motor build it to handle 1000 it will be cheaper in the lone run. Good luck

Get a hold of Darin Rausch at Rausch Specialty if anyone can help you out he should be able too.

It's pulling. I think that the speed limit classes are very tough. takes more work to win. Thanks and good luck this coming year.

Steve what type of tractor do you pull? What class. I would love to see picture of your tractor. good luck

Thank you. I did okay. Made 27 hooks, Was points champion in one of the clubs I pulled with. The biggest issue I had was learn how to weight the tractor. where do you pull at. Here is my last hook which was my best run of the year
