Stuck Throttle

Doug George · 2021-09-13T13:51:42Z

Just had my throttle get stuck coming out of corner 13 at Calabogie Motorsports Park. Here's a video of the result:ECU data and the video both show that when I came off the throttle, it didn't go all the way off. From there I had just two seconds to diagnose and recover before I was onto the grass... and I obviously didn't make it. When I didn't get the expected deceleration I instinctively increased brake pressure, which locked up the fronts and made steering impossible. Only then did I realize the throttle was stuck and put the clutch in. But I was already going into the grass, and from there two more seconds to impact. Unlucky but it could have happened at a much worse place. Radical Canada just happened to be at the track that day. By the following day they had the front right put back together. The nose is going to need a bit of duck tape LOL. It's totally shredded; they are going to get their fiberglass guy to look at it, but I'll be amazed if he can put Humpty Dumpty back together again. The pedal works fine - first thing I checked when I got out of the car. Was easy to see since the front of the car got removed. The Radical tech is certain the problem was at the engine end; he's taken the throttle bodies back to the shop for a closer inspection. If he can't determine a clear and obvious cause then I'm going to get them to replace the whole assembly. Not worth risking a repeat. So my question is... how common is this sort of thing? My wife is really interested in the answer LOL.

@lunatic Unfortunately Radical Canada did not find a smoking gun. They did replace the blipper and of course the throttle cable. There was nothing wrong with the springs at either end.

After some very cautious laps I did a couple of longer sessions on Saturday, with no issues throughout.
