I have a dry break but but either way I have made a project of eliminating rivet drilling from the body panel removal process. I made this ring, welded in 5mm nuts, glued and riveted it to the backsi...

@speedsmith you can see from the pictures how the original dry break fuel cap was attached - with rivets against the fibreglass. The filler cap i replaced it with came with an additional metal backp...

@nautoncall The Quaife Hypoid (QBE72G) and Hewland JFR have nearly identical technical specifications. See this response from Phil Abbott about the history of them in the SR8: Question 4 - "I'm intere...

Glad to see that you have made some progress with this! As Rod as mentioned it is a Jenvey sensor, the TP1. The TP11 they offer has the same linearisation and is made by Variohm, the same people that ...

In my case, there were warning signs. I just didn't notice it. MoTeC's i2 data analysis software has a powerful feature that highlights diagnostics -- it's just that I didn't know that until after the...

Thankyou John, My engine is finally running well and the TPS is functioning correctly. I have not removed it to get a part number but I assume that it's a different part from your SR8. Don

Sensor itself is normally the problem with these. Glad you have sorted it. Keep an eye on the reading, in earlier cars there is changes to the map depending on air temp but the sensors have not always...

Changed the air temp sensor and fixed the issue. Still does not understand how to read the ECU pinout.

FWIW, my left-bank TPS failed at Miami-Homestead this past weekend. 2 years old, maybe 40 hours on it. I'll be replacing mine annually from now on. 😯

For reference, I just got a dealer quote on Radical's new cast uprights: $1,748 ea.

Thanks to Charlie, David and Rod. My TPS has some numbers on it so I'll see if I can find a new one with those numbers. Might not be like yours since my wires are Red, Yellow, and Green. Trying to get...

Hello Dan and Charley, Some progress today. First thing I did was make sure that the engine would run. Without changing anything, it started and idled; however, it was a low idle, ran rough and stumbl...

@speedstarincdjb Hi Don. I have a recent story to tell about TPS which might be relevant; I assure you I do not mean to hijack your interesting thread. I was at the Radical Cup Sebring official te...

@davidf ... Great insight David. I don't know much about the TPS either.. but I do know where to buy them as I purchased a spare based on some previous comments about their reliability. Here's what ...

@rjbender Hi Rod. Yes, and your way makes sense. On the main wing, lowest down force would be the 4th from the bottom. "From the bottom" is specified in the user manual setup sheet, and I have int...
