I did some number crunching on keeping my 5 3/4" Exploder pulley and what the difference would be if I dropped down to the 4 1/2" pulley PSC now wants me to use...
If I'm idling at my same 800 rpm with a smaller 4 1/2" pulley on my pump it would be the equivalent of idling at 1022rpm now with the size of the current pulley...
SO I went out to the Bronco and cranked the strg wheel as fast as I could at 800...definitely pushing against the ram
--- but I'm surprised how much resistance it takes to turn the wheel...no pinky spinning the wheel on this...
Increased rpm to 1050 or so and I was still against the ram - but it didn't seem to be as much...
Raised the front end off the floor and did both 800 and 1050 rpm "crank the strg wheel" test...felt exactly the same. so it's not the resistance of the tires causing me to use a fair bit of effort to turn the strg wheel on a power strg system AND ram assist...
Went out to my wife's Honda CRV and cranked the wheel as fast as I could at idle...WOW, this is what I want...easy and as fast as I could turn it. Damn Japanese... lol
Went out to the barn and fired up my Duramax...almost the same as the Bronco...same stiffness to turn the wheel but I didn't feel like I was "up against" the ram at all. 800 and 1050 (appr) both felt the same.
Does the CBR pump use the same 3 bolt mounting holes as the SSR/Trailblazer/LS2 pump???
Not knowing the vintage of the CRV, but most of the new cars are electric power steering. No pump at all. An electric motor often in the steering column does the assist directly. The rack and pinion is manual. The new F150 has been electric rack for a few years now. Big motors, high amp draw. Open the hood and look for power steering fluid
