Do we know why that rule exists? Has anyone requested that NHRA change that? Every manufacturer has big power turbo 4's and 6's now.

Maybe Mike D at Ford could take up the charge to change that.

Yes, I have asked. As I have raced 4 cylinder cars in SS since the mid '80's, I had hoped that I had some 'cred' to get it done but no luck. Didn't get an answer, just no change and no response why.

How about .5 under, and be able to drive it to and from the strip using the cruise control and A/C?

When the 2.3 EB Mustang came out in the guide a few weeks ago, I looked into what it would take to run 1.00 under.

Would you mind me asking what you think it would take?

Then I realized that someone is going to blast the index with that combo and in less than a year it will be in F or G Stock

The F/SA index is 11.85. If that happened, then a decent converter and a lightweight set of brakes might be in order. I suspect that people smarter than me would still be able to make these cars comfortably run under.

Yep. I still have the e-mails.
1996 and newer with a 15 % reduction would be nice.

Doesn't seem like it will happen now so all the '96-'07 combos are stuck with what they are I suppose.
Just a hand full of the 1996-2007 production cars are running in Stock now so there are all those combos in the guide that will never be tried.

Too bad because there are so many really nice condition OBD II cars out there cheap

Post # 27 is a prime example. Stock convertor, half shafts, stock intercooler.

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. The roll bar and driveshaft loop are easy adds.

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.

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

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.

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

Yup...

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

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.

I think you will find that this engine does not have a damper of any kind on it.

I believe that it has a balancer on it. The picture on the Ford Performance website looks like a balancer.

I know the old 2.3 Turbo Ford ( Pinto based engine) does not use a damper. Not sure about the EB

.

I think the factory intercooler will be fine.

I believe the 2.3EB uses direct injection at super high PSI numbers.
Might have to locate the sample valve in line between the tank and where it feeds into the high pressure direct injection pump.

It's not simple like the older efi cars

Understood. My factory training is only current through 1990.
