Triple OG

I didnt present too many conclusions because I wanted your opinions and feedback based on your own experiences. I don't know the exact material, but it is similar to concrete and therfor only has valuable strength in compression. The forces on the set material once the head is removed would mostly be in compression since the grout wants to retain its shape and the block wants to return to its relaxed state since it's still within the elastic region. The grout would theoretically make the block more rigid. The exact amount would take a better setup on my end. Thought experiment: Instead of aliens, twist your favorite fleshlite. Now fill it with grout and allow it to sit for a week. Now try to twist it again. Observe what you see. Now get your other one and blow into it. Observe what you see. Now put it into a can and fill the space between your fleshlite and the can. After it sets blow into it. Less movement in torsion and less expansion i hope.

I'm surprised there isn't any interest in this.

I had some time over the last week and decided to test if block filler will hold the blocks shape similar to a torque plate after the head has been removed. 1, 3 and 5 were measured at 9 points each before and after. MY goal was to see how much impact a torque plate has on the shape of the bore. The first set of measurements were taken with the main girdle and head off with no filler. The block was then filled with grout up to the water pump (half fill) and the girdle and head were torqued to spec. The block sat leveled for 7 days and was disassembled. The second set of measurements were then taken. Results are presented as the delta between the original and new value. All values in the PowerPoint are presented in inches because America. The largest changes were 0.0035 in or 0.0889 mm between cylinders 3 and 5. There may have been even greater changes if the block was filled to the top with grout. I hope this information is useful and I'm curious to hear what you guys think. Notes: My block had the most wear in cylinders 3 and 4. Due to the amount of change in 3, I measured 2, 4 and 6 separately. 4 was also all over the place. 6 was similar to 1. They were not included to keep the test objective.

So....I managed to fix the belt coming off problem, but unfortunately i destroyed my oil pump. While testing and hitting my rev limiter a bunch, my oil pump took a shit. I actually heard it break. In my great wisdom i decided to hit redline 5 times (original plan). Lowered it to 7500 for the soft limiter. Normally it would come off on the first go. The 6th time I hit the limiter the pump broke and as i began accelerating again and hit it the 7th time, oil pressure dropped and the protection kicked in. It actually made a "tink" as if i dropped something hollow. The motor is pulled and should be rebuilt and put back in 3 weeks. No bearings were spun and i could have gotten away with simply replacing the pump, but since i had to pull the motor....might as well build it I made a billet tensioner and the belt stayed on without getting frayed. I also made one for a friends R33, but I was thinking of using a hydraulic unit to keep constant pressure on it when the belt stretches.

I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
