no mach 8's, they were 7x.22's
oh and the II pump had stock holders and small dv's, for race pump and the price you would have thought that would have been aready done
 
I'v got one, haven't pulled with it yet. But I will, you can be on it..
 
How to get your truck to loap...

u don't necessarily need the 13mm plungers to loap. u just get a fuel pump timing kit from your local snap-on man and advance your timing about 19 degree, note: advance not retard. or it won't run. U will probably have to take your intake heater off because u will probably have to start it with ether. but it will loap. especially if u get some .120 stainless steel fuel lines on and shut ur return off. Note: don't go over 19 degrees!
 
that really doesn't work because you will blow your fuel filter sealing ring off the top of your filter if you try to run it like that with the return shut off past the filter and you shouldn't have to use either until your timing is up in the 40's i have ran mine with the timing in the mid 30s and it still starts really good considering.

Taking a pump to 19 degrees will not make it lope. The .120 lines can offer some lope. Governor setup on the pump as well as pump cam has more to do with the lope than timing.

My truck at 30 degrees doesn't lope much at all.
 
advancing timing

Thats the first I've heard of anyone going over 19 Degrees and not having problems. how much lift did you read on the #1 plunger? with dial indicator when you converted from degrees? If thats tru I can go a lot more. I probably didn't see the difference because I put my .120 fuel lines on when I did mine It seemed to loap plenty for me. Its already a rough ride If I drive it on the street. you can feel the loap in the power on the street. Unless your standin on it.

Don't remember, looked at the timing chart. What class are you wanting to run in the ITPA?? The 2.8 class?
 
Do your homework. I know of one guy in that class that runs 38 degrees of timing and can spin 5000+ going down the track. Most of the trucks in that class are pretty extreme. I here they have a 2.5 class that might be a better class to start in, unless your planning on putting about 12K into the engine compartment, your probably not gonna be very competitive in the 2.8 class
 
there are tons of trucks running 20 to 30 degrees timing. Your pump flow, injector line and injectors have a lot to do with it, you can have a truck with big injectors run smooth stick a little set in it and it might lope like crazy. alot of it is in the pump in my opinion.
 
They don't allow water in the 2.5 class do they?

Yeah I agree the loap would be different on just about every truck because of the different set ups, and about the return shut off. I know thats not recomended but I've seen so many people do it I had to try it. I plugged mine at each injector about 2 years ago. and haven't had any oring problems yet.

what class do they? because I already have that. and I have seen one truck I know of pull in the 2.8 with it. of course he might have been cheating
 
ITPA?? Are you talking Indiana or Illinois? Indiana 2.8 does not allow water.

Who had the water that you saw? What water kit do you have?
 
I'm not sure what his name is but He lives here in Crawfordsville, IN he had a snowperformance water/methanol kit stage 2. I got the same thing with an upgraded 220psi pump and the biggest nozzles they had. He has a kinda metalic color regular cab long bed truck. pulled at Greencastle IN also at the Diesel Xtravaganza, and broke.
 
Indiana Truck pullers doesn't have a diesel class that allows water. There will be some trucks in the 2.8 class this year pushing 950 hp. So pretty much your gonna need a 13mm pump, and some engine work, driveline work, etc. I don't think the snow kits move nearly enough water to do much good at the HP level.
