Hi Java (@javaskrrt), welcome to the Registry! What chassis number car did you get? If your car is a 2021 it would be an XX. The XX has data logging capability built into the steering wheel wheel /...

@rjbender you're awesome. Very interesting! I disassembled my units this afternoon. Hand written values (that have mostly worn off) on the springs seem to indicate 500F / 550R. This is a little close...

I see the handbook now and its showing 450F / 550R. I always forget to look in the official docs before I look here!

I have done an external blanket and welded a bung on to the swirl pot for an immersion element. Both are slow I don't love either method as it relies on the onboard water pump and too much human inter...

Hi Walter, That is the exact system I used for many years while racing dirt midgets. It works wonderfully! We are in the process of designing the best way to use it on radical this winter. I will post...

@rjbender THANK YOU!!

Wondering if an RSX or XX owner can grab a couple of quick rear diffuser measurements for me? See pict for the two widths I am looking for. Attachment : 3rdgenreardiffuser.jpg Inside measuremen...

Yes that is the one I purchased. I couldn't get it to fit well under the splitter and the build quality was not good. There was lots of slop in everything and sharp, un-deburred edges on the tubes

I just purchased an SR3 recently and couldn't find a lift to lift up the front of the car. I bought a Grey Steel one from a company in the UK and it just didn't work well, so I ended up building my ow...

@rojid Yes heat will be required. If you’re changing all the bearings too, you’ll need heat to get the old outer bearing races out. The magnetic filter is a much better idea than the rock catcher. Th...

@alex-heavens my GDU is from 2021, I've studied the service guide + bulletin on the upgrade kit, which comes with the wider forward + thinner reverse gears you speak of + a few other bits. I will be ...

@rojid In the case of totally dry and you have to prime the pump, I would personally leave the inlet pipe on the pump and take the other end off the bottom of the gdu, rotate the pipe so it is highe...

@alex-heavens unfortunately i struggle to think any other way 😭 😀 it's rebuild time, both engine and GDU. I saw the notes from the radical technical bulletins and it says priming is a...

@rojid I think you are overthinking this a bit. I’ve somehow got away without ever having to prime the pump, although I do agree it’s a good idea to do, but I would probably only ever do it if the gdu...

for those of you that are interested i have machined tooling to service and replace the bearing in the radical uprights. the cost is $435.00 per upright includes shipping back to you. the service incl...
