Retired - And Still UTVUNderground Approved!!!!
I put this up on RZRforums.net in their 570 section and Joey asked me to put it up here as well.
Howdy all 570 owners! We are racing a RZR570 in the Production 700 class at WORCS and since this area is 570 specific I thought I would let you guys know what we are up to.
For those that don’t know us my name is Doug and my son, Cody “Code†Rahders, is the driver. Over the last 4.5 years he has raced short course in a Super Stock Rhino, full built Modified Rhino, and the last two seasons a SR1 at LOORRS.
This season he is racing a SuperLite truck at the Lucas Oil Regional’s and the RZR570 at WORCS.
First, the car was supplied to us by Polaris through JoeyD of UTV Underground.com. The plan, see what we can accomplish against racing against the Rhinos. Our first impression is, on hard pack this car is quick….very quick, it governs out at 57mph and gets there FAST but, they say there’s no replacement for displacement so we’ll see how it handles deep sand and mud.
Justin at Cognito Motorsports picked the car up and supplied the race legal cage. Pro Armor hooked us up with doors and front bumper, then it was off to round 1 at Glen Helen to see what Code could do with a stock 570. It was so muddy and he was worried about bending up the brand new car so he played it safe and took last through the first turn then worked on the pack one by one.
By the 2nd to last lap he was within 4 seconds of 2nd place but knocked a bead off the left front and finished 4th, total damage, bent front bumper and broken RF hub.
The car was just too narrow for WORCS so it went back to Cognito Motorsports where Justin developed a +5†suspension for it. Fox Racing Shox jumped on board and supplied the shocks, we then picked up some DWT Diablo beadlocks from Black Rhino and ITP ATR tires and it was off to Primm.
At Primm the suspension worked very good but a mishap at the end of lap one left a hole in the radiator and a DNF for the day.
The car then went with us where we have made the following changes;
1. I relocated the radiator to the back of the cage and gusseted the rear arm supports,
2. Cognito Motorsports supplied us with lightened billet aluminum hubs,
3. Chris Hawks at Benchmark Performance was able to reflash the ECU to safely provide us with an additional 1000 RPM’s of engine speed,
4. Nate at ALBA provided us with a set of drop in cam shafts designed to put more emphasis on the RZRs already potent midrange,
5. Nate also had custom fuel controllers made to tweak the air/fuel ratio.
The car is currently at MotoWorld of El Cajon getting the rod update, Ill have back on Wednesday then install the cams and schedule some time with Nate to dyno tune the engine. Once that's completed it’s off Havasu to see if our work pays off.
Couple of things I’m thinking of, I saw the new AC1000 for the first time yesterday, I like where the radiators is located and wonder if I can make that work on the 570, its trick IMO. We also have a spare cylinder and head, the head is similar to the XP but is not finished off as clean as it big brother is so we're looking into porting and better valves. Nate has CP making some pistons to try, and I am working on a possible stroker kit, depends on how the cams and piston work.
I’ve always liked being the underdog, were taking a brand new 50" trail car and putting up against seasoned Rhino's at WORCS. The 570 is a badass little car with a ton of potential so, why do all this work to the 570 when we could have just done an XP? If you have to ask you’re probably not a racer…lol, stay tuned for updates.
