Actually, I've seen that car from other angles, and I think it has a giant aftermarket intercooler.

But then again, he's running several tenths under the B/SA index in a street-driven car with air-conditioning.

3" o/r downpipe, tune, and NHRA spec fuel on the approved list.
You should be able to run index easy. You will need a fuel sampling valve in the car's fuel system and submit samples after a qualifying run.

I think all these new cars come with a Schrader valve test port on the fuel rail, don't they?

The roll bar and driveshaft loop are easy adds.

Yup...

The tune is the key with that 2.3EB.
Those cars are soooo under rated and de-tuned from the factory because Ford has to deal with the habits of the driving public and also for warranty reasons.

If they released the cars with a better tune they would risk someone putting lousy 87 octane fuel in it and detonating the engine under warranty so there are safeguards built into the factory tune.

I understand this well- I was a Ford factory-trained technician for many years.

If that combo ever gets factored to G then it will need an SFI harmonic balancer

Okay, well that sucks. I hope somebody makes an SFI 18.1 damper for it. And if not, I hope that weight can be added to run H or wherever you don't need one.
