Turbo Vector---Bender rocks!

[Thrusted Vector]

Well,we got our bender turbo kit for the Vector.Having instsalled the MCX kit on mine I was expecting a long job.boy was I wrong.First of all we didn't need to put a different head gasket in,left that stock.All the parts fit perfect,clearly labled and the instructions concise,well a few were for the RX1,but at least we could phone the manufacturer for clarification.Everything fit where it was supposed to.The gang at Bender were fabulous with the help.Time to start it up,turned over half a turn and fired.First thing we noticed is that the Bender kit has better throttle responce,a big hit as the Vector doesn't have ultra quick responce to start with,but it's quicker than the MCX,likely to do with the fact that the MCX kit has a head gasket spacer.It ran flawless.Time to go the hills.Our kit came with a two stage switch,4-8 lb switch,so we can play around a bit.Well the kit ran flawless on the hill as well,before we went out I shortened the rod by a couple of turns anticipating somebody not putting the kit together with the right amount of boost,and because more is better.On low boost it made 6lbs on high it made 12 lbs,gggggiddy-up go,On a steep pitch with a foot and half of frech snow,70mph track speed,no off throttle gurgles,get on and off the throttle and it ran great.The beauty about this kit is that you don't need to shop full of tools to put it together,you don't need to be a master mechanic to install it,if you can change your own sliders I think you can install this kit.If you don't need 200 plus hp,and 185 will get you by,this kit is fun to ride.Thank you Bender Racing for building a kit that you don't have to f#@ck with.

Why only 185 hp when the RX1 makes 245 hp at 12# boost?

Link, hows it pull compared to the MC when they both have the same boost #s? We have a guy just north of me with one of those Super Chargers from MPI and I guess the throttle response is nuts compared to the Turbo's (Never seen it myself but my buddy with a Vector Turbo saw it) Take it you got some snow now to ride, or did you heli them to the top?

I would think lbs vs lbs the Bender will have the egde with the cooler intake charge.

It's hard to say,cause the MCX has a 159 and extroverts,but i'd say that they are both pretty close,pound for pound of boost,it's just that the bender kit was way easier to install,no fiddling,better throttle response and much cleaner jetting.As far as getting to the snow it's a long drive to snow,but it was still good.It's funny there is only so many places to go and everyone is hiding them and keeping them a secret.

I've been running my Mtn Vector for 6-wks now. I've been running 14#'s boost since day two. I ride from 6,000-9,000ft in elevation. Jetting for this elevation and boost took some time to figure out. Bender was not much help since the sled and turbo kit were so new. I've prety much got it dialed in now and this thing rocks. I'm estimating on high boost that I have about 250-hp. I base this on my brothers RX-1 Stage Two turbo on low boost (240-hp). I can handily beet him in a drag when he's on low boost. All I have left is some clutching to fine tune.

Cool,life is good at 14#of boost.I'm so impressed with this engine.

Vector turbo front mount

Gee this Vector keeps surpriseing the RX1 guys with performance.
Heard that Nick from Vernon Yamaha had his front mount out on weekend and it rocks even against big boost RX1's
RX1 guy said he blew by him like nothing!
Oh the little 3 cyl likes a turbo.

I love my boosted Vector. Would like a little cleaner jetting on the bottom though. Perhaps some of you guys can post what you are running. Might have to make some remote fuel screw adjusters as that seems to be the touchy area. I am running 12-13lbs on premium pump.

Post to SLYMAX

Since Yamaha, in its infinite wisdom, decided to make the needles non adustable in the Vector, it is very dificult to get the the engine to "come off idle" cleanly. What I did to correct this problem was to machine the fixed clip, on the needle, down two of the needle spacer washers (the little white nylon washers used to adjust the needle on a std mikuni half a clip position). And machined the slide where the needle clip sits another two washer thickness. This in essence lowers the needle about two clip positions (actually 0.120"). At the elevation that I ride this eliminated the litle blubber that existed just as I came off idle. The sled now has a crisp clean respose throughout the powerband. I have a friend that did all the machining on the slide and none on the needle. I elected the route I took to make sure there was still enough on the slide as to not remove the internal guiuide bore of the slide. I'm running 140 main jets, stock pilot jets at 2-1/2 turns out and a 600 peta tube jet.

I was thinking of trimming down the slides to lower the needles also. Wondered if anyone else had done it. My MC kit doesn't use a peta tube, not sure how that system works. It runs good from mid up but just off idle seems to be the touchy area. I ride at 2-3000' mostly and 6-8000' in the Mtns.

I'm sitting at 1.5 turns on the fuel screw and it is running better than ever. I'll probably try 1.75 turns next because right now the only hesitation is when I hit full throttle in a drag race. Seems to come out of the hole better by starting with half throttle than going to full throttle. And no, track spin wasn't an issue with the 2.5" paddles.
