What matters is how far you can go at race speed. Find out. Record it carefully. Keep track of distance traveled on track during race. OEM dash gauge is useless.

Let me take a guess. Run a bigger fuel cell ? Chump allow stock capacity +2 gallons (more depending on tank size, but for Miata it is 2).

Nope, we run a completely stock fuel tank...for that matter, a completely stock car.

1. Hide aftermarket ECU (I.e. megasquirt) in stock ECU box.
2. Lean out
3. ???
4. Profit

Just put one of those magnet pill things around the fuel line. Supposed to increase mileage by up to 30%. That should do it.

You dont have to use that big of a crystal...
The other way to do it is to get the ecu reflashed.

We run a 95 325i in Chump.
With the stock diff (3.46 gears), we can go 2 hours. We changed the rear end to a 3.73 from the junkyard and the car started sputtering through turn 4+5 in Portland after 1:20h.
While it was the perfect ration for that track (just hit redline at the end of the straight), not being able to run the full 2 h cost us.

So slightly lower gearing might get you through 2h.

We calculated it the easy and safe way....fill the tank to the brim....run like hell for 20 min straight...flat out 7000rpm shifts...etc....

fill with fuel...

do maths

assume the shitty miata will only run down to 10-11 gallons...

The run it till it hicups hard has run us out of fuel on track before...which sucks in the summer.

I like your thinking David.

Except for the fact that we have NEVER truly cheated a Lemons/Chump Car event ever.
