Good to see progress on this! That's a proper oil and water mix, were you able to pressure test it before you stripped it down? Might be worth checking that no core plugs in the cylinder head have po...

@parsonsj sorry John, I have only just noted this! We have used the oil thermostats like John W has here in a number of 7 style cars and they are great, they take a lot of the trouble out of worrying ...

@rjbender Hi Rod, Glad you are making progress. The fitting needs to go into the bottom pipe that goes from the water pump to the fitting on the cylinder barrel. Attached is a picture. (Personally I w...

Another thought for you - and I am not trying to be negative just give you feedback, we tried a Carbon silencer on an SR3 a number of years back and the silencer failed due to the lack or air flow/hea...

They do sound interesting, we have recently had one done on the RLM Caterham. The guy who made it is concerned over the longevity of it in this application and hopes we will see a couple of seasons. I...

@ajiman as Charlie said it is important to know that Radical log hours based on total running time. This means that an engine that has done 10-15 hours on track could be well over. I know its a stupid...

@ajiman That is perfect, that is the later one used. The early versions of this did sometimes have problems with the temp reading and turning in the housing. You want to be replacing it with Bosch 0 2...

Posted by: @ajiman I have an additional question. Is the temperature sensor on the left side of the block an OEM hayabusa sensor? Or is it something different? Thinking about replacing as the reading...

@ajiman That additional spacer is just for housing the additional temperature sensor. This was used on earlier cars for the dash, so if you are not using the whole block can be removed. The thermostat...

Thanks Charley, @DJW feel free to PM or call if I can help out at all. There are a number of small mods that are done to the standard engine to ensure reliability in the car and most of them are not t...

@gwt561324 They fit right in 😛 Unlike the 1720cc that needs a couple of mods!

Just thought you might enjoy a video of our latest 1596cc Hayabusa engine on the engine dyno putting out 280hp at the output shaft! Attachment : 9475f8a0-6ee6-4980-998c-a5235bf2e5d1.MP4 ...

As @Rjbender says your car will not have a low fuel level light, that will be low fuel pressure. This is consistent with the fact that you cannot hear the pump prime when you turn the power on. Is it ...

As Charlie said, my first thought would be that you have a stuck float bowl so the carbs are constantly filing with fuel. It could be a bit of dirt/debris stuck on the float seal. I think (but don't h...

@raider89 That is interesting. I know the factory and the dealers know what they are doing but personally I would not recommend this. The scavenge frame/screen that you mentions locates in a cut out ...
