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...

The Handling Guide has this to say about aero adjustments: This is a very brief description, but that is basically all there is to it. To determine whether a change has helped or hurt, one can ana...

My perspective is just for SR3. TL;DR: hole 3 from the bottom on the main wing, 6 from the bottom on the subwing, and no diveplanes on the nose. Very few race teams/drivers will run dive planes on...

Rod, Good advice. I can see now that tapping on the drive shaft end would have worked also. I saw that when I was working but was unsure since this was the first time I had done this on a Radical an...

@schneller - G'day Ron, You can see the end of the shaft up the middle of the hub. I think another way around that issue would have been to use a brass drift (... or even a piece of hardwood that wo...

Ok. Got it worked out. The metal tripod joint housing had surface rust and was stuck in the hub. I think the splines had rusted and fused to the hub side. I sprayed penetrating oil in the area in ...

@bird - Hi Jay, Main dimensions are 40mm wide and 215mm long. The material I used is 2.5mm thick (anything between 1.5 and 3mm would work really, as long as it can be formed to shape with heat.... o...

Hello Charley. I've been out of town and will be trying Dan's suggestions this week. I've also got a new temp sensor and new baro sensor to try. Don

@charleyhradicalsportscarregistry-com Could be. Or maybe the V8s are different? I think this might be a question for "Ask Phil" ? 🙂
