This would be amazing! But I want to make sure that it doesn’t kill low end grunt in first gear. I need that for pulling power more than I need the top speed.

48 MPH would be acceptable and a HUGE improvement over the factory setting. With my current tire/wheel setup, I'm able to hit 41 MPH, however, it's all but impossible to maintain that speed since I'm constantly bouncing off the rev limiter.
I am really only considering this modification for the times I use my P520 on the street. I just want to be able to cruise at a consistent, and honest 45MPH on the street and not completely stress the machine.

This does not what so ever kill low end grunt. In the test video I have a place card of notes after one of the runs with a break down of the first final ratio compared to the first final ratio of a pioneer 700. What I can tell you that the video shows and I can feel is when it has a 1000lb load behind it, and you are in 3rd/4th/5th gear you can feel the drag more there. Not a huge difference but there is a difference and the test data shows it.

It should be mentioned, I wasn't on the rev limiter with these runs, it just runs out of power. Since I did the 520cc mod it will pull to the rev limiter but I don't have a gps in it anymore..... I'd guess 54-55 mph now, she's screaming at that speed though. 😬
I'm done messing with the 475/520 engine now though, the next mod is going to be a P1K/T1K transplant 😈

Great to know! Thank you!
And....you better not think you just need one P1K/T1K engine....you need two! One for yours and one for mine!

OK,
First and foremost this was a great series. I have gone back and watched the results video at least 4 times now so I can understand what effect this will have at RPM and speed. I very much appreciate the time and effort it took to do this project and all of the video work.
I like I would love to have the additional top speed; I'm still trying to figure out if the work is worth the return. I'm not really scared to take the P520 apart, as I just got done doing a lot of mods that required taking major components out and replacing them. I'm just not sure that my attention span is long enough to do the mod.
Is anyone planning on doing this?

Thanks! I’ve been trying to get some stuff together for some other things I lined up for the channel but have not had time. I did end up building a custom dump bed for the Honda and I’m going to try and post a video of the parts/cuts/tricks to build it and some working video with the new bed. It will not be nearly as detailed as the gear swap vid. I figure anyone who would take on this project is looking for ideas more than the exact step by step.

Plenty already have, I've mailed out about 30-40 of the washers/shims for the speed sensor. I did my P5 back in '18, the P5.2 is no different

I'm considering it.
I would very much prefer to have the new 'high-speed' gears machined and ready for installation 'before' the P520 is torn apart.
