Yes, that's where we hooked up our pressure gauge and test valve. It helps if you have a jumper switch to the fuel pump relay, for a serious effort.

Actually they initially did have the service port on all the fuel injection systems, but about the time they went to a return-less system and even more so now that a lot of these engines are Direct Injection, there is no service port on the rail.

and yes to quote my original reply, I'm very interested in this combo, just don't want it to be destroyed before I can afford to try it..

I would love to get a group of us together to petition NHRA to change the V8 only rule for SS/GT. I can count the number of cars on one one (maybe it would take 2) hand that are being produced with a V8 these days. Would be nice if we could run those engines, I have talked to Don Kennedy about getting the rule changed as I know he was heavily involved in writing the SS/GT rulebook. He is on board and has attempted to make some calls, no luck getting who he wants on the phone yet but this was a very recent idea.. If there are more people out there interested, keep pushing them for change. It will take a group of us showing interest over just one guy.

Just some info on the engine at hand. There are some very big issues with this engine when you make a lot of power over stock. If someone is really wanting to run this combo I suggest doing your research before turning it up much. Block and Intercooler are the first 2 that come to mind, but I'm not an expert yet and have just dabbled in my research.

I am familiar with Ecoboost / Duratec engines, I am not aware of any block strength issues. There are a couple of minor weak areas that need attention but very easy and inexpensive to fix. What do you know that I don't?

Regarding the damper, I guess one persons pulley is another man's damper. I have one of these in my shop and it looks like a pulley to me. That being said, the Ford 2.3 single OHC motor doesn't technically have a damper either. Mine does because I retrofitted an SBC unit to it but not the way it comes from the factory.

The car isn't quite legal for Stock Eliminator, but dang, if I could even get one to run a full second SLOWER than this guy's 11.03 @ 122, I'd still be more than six tenths under the K/SA index.

What do you mean " not quite legal" what would keep this car from running stock.

It better have the stock exhaust manifold as it is cast into the head, wonder how they check the exhaust cc's on this one for a teardown? Has anyone actually looked at this motor or is it just something they read about in Hot Dog magazine?

Here is a picture of the exhaust side of the head.

I'm not planning on setting any records or racing at Indy. I'd just like to comfortably run under the index. What are the odds that I'd be subjected to a tear-down?

here is the description for the head from the Ford Performance website.



Fits 2015-2018 Mustang EcoBoost engines
This is the production IEP (integrated exhaust port) cylinder head
Includes water jacket plugs and valve seals
Does not include valves, valve springs, retainers, valve locks or tappets.
Same cylinder head used in Brad Gusler's NMRA 1/4 mile record setting EcoBoost Mustang

I'm not any further along than you are, but I'm finding that most reports of damaged engines relate to inadequate octane, poor fuel quality, using the wrong "tune" software, using generic "tune" software that is not a close enough match for a specific combination, and/or a defective/failed fuel pressure sensor on the low-pressure side of the fuel supply system under the hood.

Most of those failures look preventable to me.

That fuel pressure sensor will apparently cause the engine to lean out under boost. It can be monitored in real time, using an aftermarket hand-held "tuner". And Ford has an updated replacement part available.
