Best gauges and mount for mpi trail kit

[jakethesnake]

looking for best gauge setup for the best price. Would like to have to separate gauges. Boost and AFR. Please lead me the right way since I have a new motor 16!!

It's not separate, but the Koso is really good and you can't beat the price. Check out Amazon.

check out OSP. They make a very nice one that will do both gauges

I'm new to the turbo/gauge world and did a ton of research this summer and came to the conclusion that there doesn't seem to be a best set up...they all seem to have faults. I went with a Innovate digital AFR gauge that is water resistant...found out later that the sensors were failing on these which seem to be due to bung placement so I changed the placement of my bung (before turbo)...My boost gauge is a liquid filled Autometer gauge...a lot of mountain riders I talked to swear by it and it's big enough so I can see it...I used a trailer 4 wire connector to hook everything up and I bought Tomcats duez fastener kit so that I can remove the hood easily on the trail. The third gauge is a marine voltage gauge I picked up on ebay...two front gauges are in an OSP mount and the boost gauge is in an autometer cup.

I have tried 3 different digital boost gauges the dragon does not show 10ths so I moved to innovative and it worked almost 1 season then went bad I tried another that I cannot remember the maker and it died on the 4 th ride last season and just went back to a n analog and marked the lens with a marker for 7.5 and 10 lbs and it us easier to read the needle under hard acceleration and my video camera can read it where as the digitals are not visible during playback .

As far as the age I have gone through 3 arm gauges in the past 4 years and the brand new one installed last season reads 14 !all the time.

The koso is good looking but both Yamaha Tim and Mr sled had issues with them on the first go around

My dealer installed a koso afr gauge before i bought the sled and i like it so when i bought a boost gauge i went with koso again. The afr warns you by turning red when the ratio is too high and you can set that warning value. The boost gauge is supposed to do the same but i can't find a way to set the value. You can chose between the 15 or 30 scale and from what i understand the gauge will turn red at these value, 15 psi is too high for our sled but at least the gauge record the min (vaccum)and max pressure value. Now I hope these gauge will be reliable as some here had trouble with koso gauges but so far the afr worked flawless all winter long last year.

I think the Koso that was a problem was the all in one unit and the fix was to put it on a separate switch and boot it after the sled was running

Yeah I put my Koso on a time delay relay for 10 seconds before the gauge powers up. No problems with this setup.

Muffin I can't find the koso gauge on amazon do you have a link or part number by chance?
