Having seen the data and with all the symptoms you have, along with the number of parts that you have replaced, I still believe this to be a fuel pump problem. Would also explain how the symptoms came...

Agree with everyone above on this, you are due a rebuild. As DavidF said there seems to often be problems at 45 hours + that end up resulting in a larger cost over having it done on running hours. The...

As DavidF said Rod, get some heat protection on there. Unfortunately it is bending it back over itself and cable tying to the chassis leaving as much as you can from the exhaust. As you say a port in ...

Posted by: @raider89 10,700 if I remember correctly That isn’t much of an over rev. I would definitely recommend contacting Spring Mountain to get their advice. I wouldn’t recommend putting three...

On my 2021 SR3 XX with 1500cc engine, I would like to know more about recommended engine rebuild. Is the Radical recommendation of 40 hrs mean run time or load time? My car currently has 45hrs run t...

@raider89 - the 40 hours is total run time - not load time, so you are right to be asking about a rebuild around this time.

raider89, As Rod is 100% correct (as usual). Radical recommends overhauling the 1500 engine at 40 hours TOTAL Time. Many find this unintuitive because to use an extreme example if one engine was idl...

I would be looking closely at grounds as well as all connections especially your main switch. The low voltage as well as the increase in poor running you have experienced certainly leans me in the dir...

@davidf - G'day David, Is the clearance you refer to 'under the centre wear strip' or measured in the outer edges like you have in the picture? Also, are you measuring to the splitter itself (ie to ...

I don't have any suggestions but this has been a great diagnostic thread. Hope you're able to get it sorted soon and look forward to hearing what the resolution is.

In my experience so far there seems to be a lot more issues with aftermarket units, whereas OEM never seem to go wrong unless spun! If your after a spare to get you through a day or race weekend afte...

Posted by: @davidf Posted by: @rlm-dan I have seen one recently where the voltage was dropping off enough that an engine would start and die -- I think the voltage was dropping off low enough on s...

@davidf You've been through the wringer on this one! Ok, let's talk about engine sensors and sensor wiring. I'm wondering if you've got an engine speed or engine sync sensor causing the issue. If I'm ...

David; I am curious about your 20hr axle tripod grease R&R comment above. My manual says every 10hr, which I have been doing, but seems excessive as grease still in like new condition. On a sid...

The introduction of the Life Racing ECU onto the SR3 was one of the major developments that improved the maintainability of the car. The Life Racing ECU incorporates an engine data logging system tha...
