what company sells the boost gauges for the rxtx

do you get the boost right from where the intake manafold upgrade kit is in stalled from riva kit

There are a number of online companies who sell these type gauges (digital or analog), do a search for "boost gauge", these come in all shapes and sizes. The first thing I would be asking myself is where actually to mount the gauge (this will play a key roll in which one I would decide to buy).

The boost gauge taps into the billet block-off that comes with the Riva upgrade, simply remove the brass plug and connect your boost gauge line accordingly. This is the best and most accurate location to measure boost as it measures boost inside the air intake manifold, just ahead of the valves....

seadoo3x - There are a number of gauges out there that will work. We're using an Ashcroft oil filled guage we picked up at an automotive performance shop locally.


onefasttx - Yes. That is what the small brass block-off plug in the middle is for. Make sure you use a thread sealant when installing the boost gauge and don't over tighten it.

sweet sounds good took my rxtx out last friday afternoon trim one click down from middle water temp 53 degs 1ft chop very windy 70.00 on gps i thought that was very inpressive need to install prop an pro nozzle from riva

53 degrees!?!? No thanks. Nice numbers! What rpm were you running?

rpms were 8120-8140 to high i think need to install the prop an nozzle from you guys right know i have the grate 4inch prom filter and catch can. i hit the rev limter acouple times too.

Ideally you want to keep your rpm at 8,000. The prop and nozzle will definitely let you do that and improve performance a bunch.

im trying to find a good gauge and mount myself.

I found this product that is completely waterproof

I still need to find a mount that will work on the handlebar. the smallest six mount is for 1 1/2 roll bar. Need to find a way to secure that to a 3/4 bar.
Send pics of what you went with.

i found some boost gauges today one was 49.99 an thee other was 59.99 at pepboys that seems reasonble money

Watch the pep boys stuff along with the 'cheap' brands. The accuracy of cheap gauges can sometimes be way off. Just say if your off a small little 2 lbs inacuracy. That will make a difference between thinking something is wrong with your motor or not.

thanks for the info i will spend for the 60.00 one or more for them

My personal favorate for gauges are the autometer gauges. I have owned many of them and have not had one single problem. Just bought that non autometer brand waterproof gauge and accually feel bad lol. Make sure to post pics of the install!

i just bought a sunpro boost gauge going to make my own peller for it too for waterproof

Cool! Please post pics when you install it.

FYI, just got the gauge yesterday to the link i posted above. they sent me the wrong one. I dont see whats water proof about it anyway and the wrong one they sent was waterproof kind. Its the exact same as any other gauge. I returned it for an autometer boost gauge.

ill tell you theres not to many places to put a boost gauge on these beasts any help would be nice boost roostin

I have seen some "one-off" designs to where the installer removed one of the mirrors from the mirror bracket and installed carbon fiber or an ABS type plastic in it's place, then drilled and mounted gauge/gauges. I have seen the digital type installed with velcro or two sided foam tape just under the instrument cluster....just a couple of ideas!!!!!

ya ithink i saw that somewhere on here thanks

There is a plastic product on the market that comes in several thicknesses (1/8" to 1/4"), shatter proof mirror, can be easily cut and formed to fit!!!!!
