Mpi stage 2 questions

[jim rice]

I'm running 6 pounds and haven't ran lean yet on long wot runs, I know another guy running the upgraded pump whose running 9 pounds on stock injectors

What do you consider not lean on your afr Guage

 

[Studroes144]

11.5 on 1/4 mile wot runs, and I have 2 full settings left on the gems for wot

 

[jim rice]

Does it pick up any more speed by giving it more fuel I'd rather be safe even if it ran the same or a tad slower

 

[Studroes144]

Have tried going richer at all, guess I haven't really heard of anyone going more rich than 11.5

I think long runs for some ( especially Canadians ) means 3 plus mile runs. I think this is where the stock injectors run into duty cycle problems under boost. It seems unreal for me being from a wooded hilly area that you can hold a sled wide open for miles and miles.

I wouldn't hold a stock sled wot for 3 miles

Ya our riding is nothing like that either lol, for trail riding at most there would be a 1/4 mile stretch to hold it, there is a frozen reservoir we race across that you can hold it for maybe 3/4 of a mile but we rarely run the full length, I'm not the least bit concerned about holding the sled wot for a mile cuz that won't happen

[Studroes144]

They've built 3 vipers now, 2 stage 1 kits and 1 trail turbo, the other stage 1 they built has since been all upgraded to a 325hp improved stock turbo class sled.

Are they experienced in the field

I think he's hooked up with D&D some how so the prolly do his work. He prolly gets to test at their test field, I think it's a pretty fast track.

 

[Studroes144]

D&D, yes they're quite experienced in the high performance 4 stroke world.

The test track is nothing other than a large open field but I'm 5 mins from the field and it's on the property of the family farm. I pay the price for parts and like just like everyone else, just get lots of tech help/tips since I'm able to go there most any time to chat and ride with them some throughout the winter.

D&D have a farm too is that what they do in the off season

 

[Studroes144]

No, the farm I grew up on let's them use a part of the property for the field testing..if they were to do something in the off season it definitely wouldn't be farming lol
