well first off with the 23in tires i clocked it at 54-55 on the gps i put some 25 on it and tried it today got 52 if it was picking up signal, it should be alittle faster on top with the 25 also it dont bog at all i was surpsied there just stock grizzly 660 tires. basically i want about 60mph or to keep up with my friends blaster cause it a couple of mph faster. also i have a proflow air filter and notice some of u guys have the fst intake how will that work and fit keep in mind i go in deep water so i need to keep the air pick up high as possible, also keep in mind im under warrenty still and my shop dont ike to mess with jetting and what exhaust will sound like stock still thanks guys let me know later

 

that sucks that ur shop doesnt like jetting, cuz that would be good

 

Without a pipe and jetting to go along with your filter, you will lose top end and low end power with bigger tires,it puts the gearing too high, the stock motor lugs and won't make full power. After my mods, I pull 57-58 with my Sur Tracs, they say 25, but they are barely bigger than the stock 23's, just wider. With a decent pipe and jetting to match, with those Grizz tires, you should see 60.

 

well wolvy 95 what if i get a warn 424 will that give it more top end hen 4wd is disengaged or will that not help. also to install does anything to have to be damaged or can the stock driveshaft be put back in without having to buy new parts keep in mind its and 03 if it matters thinks man let me know

 

Exhaust and if that isn't enough FST

 

03Wolf, to be honest, I never took a speed run with the 424 installed, but when I ran it down the road to test it out, the motor seemed to wind out a lot better, taking the drag of the shaft and front axles off the motor really helps a lot, that may give you the power to really wind out on top with bigger tires. All you do for the install is reuse the springs on the drive shaft ends, but you do have to cut the plastic cover over the shaft to put the 424 in place, if you want to keep the knuckles covered. I wouldn't think that would be expensive if you ever wanted to replace it if you took the 424 off in the future ( but you won't, it makes the Wolverine a lot more fun to ride.)
