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.

Jim,
As mentioned my research has been minimum at best. My point is I've read about issues some have had and without having first hand knowledge, as you have, one should probably look into these potential issues prior to encountering them.

I have been told by at least 4 people, I've discussed this combo with, that the stock intercooler has heat soak issues that would prevent this combo from being a viable car outside of class. Looking in the rule book there is nothing stating you must run the stock intercooler so this seems to be a very easy fix, just run a bigger one...

I don't want to pretend to be any kind of expert.. I've never laid my hands on one of these engines. I just was passing info on that I have found as I too am interested in running this motor someday. If we can't get the SS/GT rules changed I'll have less to worry about in terms of limitations to my combo, most likely will never have this engine in a 2015 mustang if I do it.

Are you saying that I can run a larger aftermarket intercooler in Stock Eliminator?

I'm saying the rulebook reads this:

INTERCOOLER
"Intercooler tanks must be located in the engine compartment"

I'm not sure how they could enforce a ruling of the intercooler having to remain the factory unit with this rule...

I believe this is meant for the supercharged CJ, Copo, and Drag Pak cars.

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.

It just occured to me that the fuel pressure sensor I was mentioning, might be a convenient place to "T" into the low-pressure side of the fuel supply system for fuel sampling valve- the sensor just screws into a threaded hole in the top of the fuel rail.

If the sensor is in the fuel rail I have a hard time believing it is low pressure. Your going to have to find something before the HP pump. Just doing a quick google search it sounds like the is a low pressure sensor in the fuel lines coming from the tank just as they get into the engine bay. You could probably "T" it there.
