My experiance with P3R FlyWheels
Update 2-18-2020
Dave at P3R has been fired. I heard they are servicing the cranks they have in house and finishing any orders. They maybe done. That means no one will be able to service your 1 off crank. There are 220+ cranks out there and they are going to leave everyone high and dry.
I've spoke with Gregg Dahl @ GMS Racing. They were given a P3r crank when it was 1st developed for 2 months to evaluate it. Greg would not endorse it for any high hp applications, as far as I know I have never seen a build from GMS utilize a P3r crank. That's when they asked to Frank Drago (the Walmart of Harley parts) to promote and sell them, that's when Frank contacted me to try one out. I was the 1st to have one.
The reason the crank separates is in its design, its the triangular pin and hole that keeps it from twisting is the reason it separates. There is 12 flat surfaces to get machined perfect (6 on the pin and 3 on each wheel) .001-.002 to get a good press fit, You can't machine it perfect the 1st time to those tolerances, it needs to be honed and its a lil hard to hone a triangle hole and pin like a conventional crank and pin. It ends up with some play on one of the flats and then ratchets its self off the pin.
I've been running a P3r Flywheel for a 2-3 seasons. I've not had a good experiance with them.
The crank are separating, this happens slowly, 1st the oil hole for the rods/bearing will misaligned with the cam plate oil hole/grove and it will starve the rods and bearing of oil and failure is imminent, the flywheel will keep sliding to the right the shaft will be forced into the oil pump, gears and cam plate until the pump finally brakes and you lose oil pressure. I never seen a fluctuation in oil pressure until it was too late and there was none. I never seen any tales of metal in my oil filter, i have one of the nice ones that you take apart and clean yourself, i regularly changed my oil every 2 weeks during the heat of the summer and never seen any aluminum, until it was to late and I had no oil pressure.
This happened more than once, it ruined 3 of my 117" supercharged motors and they were going to fix it again and fuk me on the 4th motor.
The 1st time we found out it split was when I sent my motor to Jim Robinson from Head Hoggers, (he didn't build it the 1st time) he notified me there was something wrong with my crank and sent me a video of it being outa shape. We sent it in and Dave from P3R said it split somehow and he would fix it. Well my builder blamed Jim Robinson, said he tried splitting the crank and it wasn't a mechanical failure. So they just pressed the crank back together, they didn't bother making a new pin or pulling it apart, when they did this they pressed it too far together and crushed the rods/bearing and then had me pay another 300.00 for a set of rods they fuked up. Mind you I paid 800.00 for what was supposed to be Carrillo Rods the 1st time that I could never see or find a Carrillo stamp, pics below. this motor ended up fuked up from the crank splitting again.
They repaired the wheels, they replaced the right had side shaft, and crank pin and rod bearings, when I recieved the flywheels, the right side wheel wasn't installed correctly not far enough and the pump would not fit due to the step in the shaft and the oiling hole didn't line up with the cam plate, they didn't press the wheels together enough or the shaft wasn't made correctly. Dave had me machine the cam plate and oil pump to make clearance for the steps in the right hand spindle for the oil pump, mind you the hole in the right shaft that feeds the oil to the rods and bearing now don't line up with the oil hole in the cam plate, I'm not the only one P3R instructed to do this I know of another crank they instructed the owner to do this, don't ever do this it will burn up your whole motor those oil holes must line up. Pics below of the mod they had me do to my SE cam plate and oil pump. It burned up this motor and it was rebuilt again.
The next time
I ran that crank for less than 4 months after its repair and it did it again, the right wheel slide on the crank pin and wiped out my oil pump, cam plate, and motor needs rebuilt again. Pics below.
P3R is claiming the oil pump is failing causing the crank to get hot and that causes the failure, don't believe this horse shit, as you can see in the pics the rods never changed colors and the bearings aren't in that bad of shape, when the crank slides of the pin, the oil holes don't line up, its a catch 22.
They are making claims that oil pump failures and or the comp bolt came loose or wasn't tightened or it was due to racing, when they claim the wheels will handle 300+ Hp. I know for a fact that my comp bolt was tight I checked it after I lost oil pressure. I know of 4-5 cranks that have failed from the exact same issue and the list is growing.
Last I heard they are now blaming the last crank failure on a procharger belt that got caught in my primary chain and ratcheted everything so tight it bent the shaft on my grudge box and it supposedly bent the crank shaft (according to them). The problem with this BS is that the crank thats made in 5 pieces is cryo treated (memory steel) if you ask Dave at P3R he will tell you you can't bend the shaft its impossible.
they cryo treat that crank shaft it can bend 1k's of times and always return home, its memory steel.
watch this video of cryo treating drill bits in the beginning he talks about his DeLorean and the door helper/tq bar assist that twists 1/2-3/4 turn a million times and never fails because of cryo treating https://youtu.be/BMoMr1vd5W0
Flywheels should never slide off the crank pin, EVER. They are now installing dual timken bearings in cases because of crank failures. They will not sell you a p3r crank without doing dual timkens now.The problem with this is the crank still wants to split, it took over 10t to press it together the 2 timkens isn't going to hold it, its going to still split put too much pressure on both timkens to the point they will fail or the cases will bust. there has to be some crank end play.
If you know or have heard of some1 that was running P3R Flywheels and had similar issues have them reach out too me.
