Ran a couple of laps. No idea where people are getting <1:56, but that's ok.
Its easy to get a sub 1:56. Just add a turbo or add some engine stages.

Or who knows, maybe some other mods I don't know about.
Seriously this is a gentleman's racing league. Just add what's on the first page people. I am stunned that people have used other parts. Its obvious, if you have to dumb down your power to meet requirements, that you have cheated with your parts. Clearly Mule wouldn't make a series where you would install the parts he says, and then need to use the power limiter.
So, Dmanaenk, I can understand how you could be weary and untrusting of some of the participants here. I think though, that 99% of the people are racing legit. I have faith that Mule will do proper checks of people's vehicles and remove them from the series if anything is suspect.
I think all cars should only have the specified parts purchased. If there are extras, whether used or not.. If asked for the car for inspection, that person should be banned.
About the sub 1:56.. It is clearly possibly. I am not the fastest here, and I have run 1.56.1xx and I don't think I have the gearing right at all. This is in the qualifying format. I have run 1:55s in practice... I think maybe even a 1:54 with tire wear off.
EDIT - So as not to double post.. I will be at the qually in 20 min. Thanks Mule!
Edit2: Just read above.. 2 shorter races might be the ticket for this one. It is fairly likely that someone will get screwed with the pit glitch. The only question for second race would be.. reverse of finish for start? Qualifying time sets grid for both? Grid order exactly as first race finish.
Personally, I like the last the best.. But all would be fair if stated pre-race.
