Well it sounds like Polaris 2016 "game changer" is a 925cc Turbo making 144 HP. I guess the 1200cc rumor will have to move on to Yamaha's new machine or wait until 2017.
So, now that the cat is out of the bag, the promoters need to hold an "emergency board meeting" and address the new, and again dominant horse-powered, RZR XP turbos and the increased performance they introduce into the class. Do they immediately allow them to race? I'm not clear on the verbiage of the new turbo rules, but I expect they were tailored around what was available at the time they were implemented. Because of their allowing turbocharged cars into the 1900 class, they opened up the proverbial can of worms. After all, it is the limitations set forth in the rulebooks that dictate whether or not a given car is safe to race at achievable speeds.
Including an OEM re-worked clutch, the 144 ponies should propel the new XP Turbo to speeds well over 90 mph. Now, I'm not a driver,. but I surely would think that the larger diameter tire discussion should be in full swing. Were talking 100 mph "golf carts" unless they mandate a simple and affordablew device, similar to a restrictor plate, to limit top speed. Anyone building off of a 2 seat platform with that kind of speed and power is nuts in my opinion. I would like a 100" + wheelbase minimum if I'm going 100 mph. Put that performance under an average chassis and driver, and I can see the carnage now.
I believe Polaris addressed the inferior drive shaft configuration, and transmission output shaft area as well as the stronger clutches. But at 144 HP, the over-leveraged and under designed 3 point motor mounts, the front upper control arm with it's vulnerable tie rod "bridge", the small diameter stock cv joints (assuming these areas remained untouched), these are all areas that are possibly at the design thresh hold of surviving i
n a recreational environment.. Given the current restrictions on track width and tire size, these cars should be kept under 90 mph, IMO. Therein lies the problem of allowing turbos into the class. They will need to make other rule adjustments to keep the cars more stable, or slow them down, which makes absolutely no sense (other than safety concerns). It is racing after all It will be interesting to see how they address these issues without causing an UN-bridgeable gap between the factory and entry level teams. I think it is inevitable that the deterioration of the class in its current form, and it's participants, starts here unless some moderate tweaking to the rules are to be done. You gotta feel for the people who have race builds in progress at this moment.
