Hi i have a question about where to post something. I had a question about late 1980's early 1990's indycars.

And i was just curious where to post it at should i post it in the the motorsports section of the board or the indycar discussion part or in the indycar technical part of the speed message board.

My question is i was watching this old race and they were taking a lap onboard with michael andretti and he was following somebody - in the draft and he got right up close behind him and his car made this noise and it sort of sounded like a revlimiter. I didn't think indycars back than had revlimiters.

This race occured back when the indycars were still using popoff valves.

The IndyCar Tech Discussion forum would be the best place. Good luck.
