RJ Anderson's RZR XP900 Race Car Build **UTVUnderground Exclusive**

[JoeyD23]

UTVUnderground.com will be working closely with Walker Evans Racing and Holz Racing to bring you up to date information surrounding the build of RJ Anderson's NEW Lucas Oil Unlimited UTV race build. The teams will take RJ's 1 year old race RZR and mesh it together with new technology from the new Polaris RZR XP900. RJ's new car will have the new trailing arm set up with custom Walker Evans Racing Shocks and of course the new DOHC Polaris Pro Star motor. It should be interesting to see how the 2 come together so stay tuned here to UTVUnderground.com for the latest on this build project!

To begin the build the existing race RZR has been stripped down 100% to the chassis and the new XP900 frame has arrived from Polaris....

[Rander637]

Yep, the new car will have Holz long travel on it as well as a kroyer motor :D

they are been with no more XMF for a long ting now...


that Kroyer motor still isn't going to beat a Muzzy motor:D

[racemx587]

Looks awesome! Can't wait to see the progress!

Haa, danny danny danny....

I guess its a good thing I have the best of both worlds! But thanks for the reminder, I've been meaning to email Rob;)

[the stripping shop]

are you doing the old car because you rolled the new xp or was it cheaper to transfer frame and just use drive train from new xp. Iam sure many rzr s guys are wondering wat this will cost.

[tyler]

I think it was more a time thing the new season is right around the corner and to build a car from scratch is time consuming.

[facteryfmf]

Nothin will transfer from the old car though.

[tatum]

Looks like they transfered the whole cage over.

[tyler]

Looks like they transfered the whole cage over.

yes cage to new framrails!! not that much has changed..

[Rander637]

This car has nothing to do with the crashed XP, which has been fixed and is currently at the king of the hammers. My old race car was bent from a crash last year and had to be fixed. With me having to race the XP this year anyways, this was the easiest and most cost effective way of doing it.

As far as going from a RZR S to RZR XP, I believe it can be done, but will require a complete rear end swap, driveline, etc. from someone like Holz or XMF..

[Zerofield]

Haa, danny danny danny....

no problem little buddy!!! it will be nice to see you guys back up front, after last season of breaking everything...

[facteryfmf]

Looks like they transfered the whole cage over.

Thats weird bc the XP is 4.5 inches longer in the wheelbase right?

I here you on the cost you would have to give your race rzrs away anyways i was just wondering on the rear transplant i think thats were you get the extra length. you should post what it would cost to transplant rear of car i beat you will get some hits on it.

[Bajaxp]

Great thread! Lots of speculation on what is going on here, but I can guarantee you that they are not 'putting a XP900 engine in a RZR S.' So here is my educated guess: they have a new stock XP900 frame. They have a crashed RZR S cage/frame. They have complete XP 900 running gear (front diff/hilliard, prop shafts, engine, rear gear case, etc). They will use the upper cage, tin, seats, fuel cell, etc from the old car and graft it onto the stock lower frame...which will obviously accomodate the new engine and drive line. Voila...new XP900 race car.

[tatum]

They showed the XP frame down to frame rails and then they just put the outer shell of the old cage on the new frame.

[Rander637]

Thats weird bc the XP is 4.5 inches longer in the wheelbase right?

Yes, but that extra wheelbase is in the frame rails, which we now have an xp frame underneath our old cage...

[facteryfmf]

Just figured you would want to push your seat back as far as you could, with how tall your ass is already... Didnt think you would be able to take advantage of that if you used your old chassis/cage

[Zerofield]

this just in...i have the plans for the whole rebuild.

the word is that they are putting a rocket engine in there!!!

[07fj]

It will be good to see RJ contending for the lead again every race.

Good luck.

Rog

[Crowdog]

Good stuff for sure! Can't wait to see RJ & the XP out on the track.

[Dudeonit]

Look forward to seeing you running up front RJ!! Thanks for the updates guys.

[Rander637]

wow plus 8? looks real nice ....

Well not a +8 from what an XP comes stock... thats just in standard rzr long travel terminology. I think its about 2.5 inches wider than a stock XP per side w/ the wheels and all. And Thanks!

thats what I'm talkin' 'bout

Ya im getting excited to drive it! Im glad to hear your gonna be back out there again Tyler!

Lookin good RJ!!!

RJ can you give us any idea on what kind of power is expected from your new motor or will this be kept a secret????

[Rander637]

[QUOTE=JoeyD23;58170]RJ can you give us any idea on what kind of power is expected from your new motor or will this be kept a secret????[/QUOTE

Joey, to be 100% honest I have no idea what kind of power this motor has. I have been in bed all week with strept throat and my guys have been busting there ass's putting the final touches together. I do know that Kevin Kroyer has been busy though and this motor will be just a "preview" of what's still to come.

Butt just to keep you guys guessing...

Rzr S= 750cc/55hp
Kroyer RZR S= 797cc/88hp

Rzr xp= 875cc/ 88ish hp
Kroyer XP= 1000cc/???hp:D

[facteryfmf]

Rumor has it... 150 

[SGM4Life]

Hey Rj how did the car feel at the races? Is it getting fixed right now?

[JoeyD23]

Well it looks like the WER Polaris RZR XP 900 will be able to get back on the track this weekend (fingers crossed)

the chassis is just about 100% repaired other than some knuckles which are still bent. The motor is at Kroyer getting the engine mounts repaired which were damaged in the violent tumble.

[WERACE]

Since we have almost 6 weeks to the next race at Glen Helen we are going to fix some of the frame damage from the 2nd round crash and clean her up a bit. She's going to get powdercoated, a couple of new body panels, new rear axles(broke R rear on Sunday) and put the big motor back in it(starting gear gave up - but still got a 3rd on Sunday with a near stock motor). Had to give her some love since she is the new points leader!

[WERACE]

Some updated pics as the parts come back from powdercoat. Figured I show some of the componets up close since the initial pictures in the build were vague.

[JoeyD23]

Damn! Those trailing arms look super sick!!!! Are those built by Holz?

[WERACE]

Oh yeah, Holz did a hell of a job on these. If I remember right they are 1" over stock. They both survived the crash from Firebird, the right one just needed a little straightening .

[WERACE]

Aluminum bodied 2.5" rear coilovers w/ high and low speed compresion adjustment. Fresh set of HRP axles.

[JoeyD23]

Shocks look sick!!!! Can those be purchased?

[motogary2]

i need some of thoes shocks for my sr1

[450grl]

I'll take a set too, while you are at it! :p

[WERACE]

Shocks look sick!!!! Can those be purchased?
Steel bodied versions are available, the aluminum has held up so we should be able to custom build them upon request.

Got the 1k back from Kroyer today, all tuned up with a new Muzzy exhaust system. Car should be 100% ready to do battle at Glen Helen...watch out Cory!

[450grl]

LOL! I'm sure it's gonna be fast as sh*t!! :) Sometimes I'm glad me and RJ are in different classes! :D

[SGM4Life]

That thing is gonna be way fast. Looks like its coming together real nice!

[Bajaxp]

Yes, great car, great motor and a great driver. Can't wait to see the qualifying times.

[WERACE]

The LOORS Glen Helen night races are only a few days away! RJ trying to land the next big deal while filling the car with Stater Bros. finest. Got the new Muzzy's 2-1-2 exhaust system all mounted up, hopefully it sounds as good as it looks. Holz Racing Products custom spindle, were switching to the stock cast steel hubs since one of the aluminum units finally gave up after 2 1/2" seasons.

[WERACE]

Finishing up some of the final details and then hopefully we can go smoke some GoodYears in the parking lot. Check this little guy out.

[JoeyD23]

is that a blower for the CVT?

[Big Guy]

Looks like a marine blower.

[Bajaxp]

It is an Orgasmatron :eek:

[WERACE]

You guys are actually all very close...

[SGM4Life]

I was waiting for that. It should of said podium on that switch! I probably would of laughed harder.

[WERACE]

Motor is dialed, 2nd fastest qualifyer behind Beat in his SR1!

[tyler]

good luck tonight :D

[rappy60guy]

rj do you or anyone have a rear shot of your car?

[WERACE]

rj do you or anyone have a rear shot of your car?

I can get you one when the car is back in the shop in a couple of weeks.
