I posted earlier that DOB was offering a mod to the Edelbrock E-Force supercharger intercooler. I e-mailed them and asked for details on the removal of the intercooler and was told

"It's real easy. Just remove the bolts and pull."

This past weekend I started working on the car and attempted to remove the intercooler. It is not real easy. In fact, it's very difficult. After talking to Edelbrock Tech Support earlier today, I was told that it is glued in place on the inside with RTV. When they have to remove one in their shop, it takes 3-4 guys pulling on a strap that is wrapped around the front hose fittings. Some part of the intercooler block is usually damaged when it is removed. Edelbrock told me the only time the intercooler block should ever be moved is when there is a leak or some other kind of failure. The intercooler block is where the Edelbrock name is. It doesn't move.IMG_0217.jpeg

So if anyone is considering this mod. Buyer Beware!

I never thought to do this. I have a 2013 with an Eforce and would have considered it an option. Did you think to contact Edelbrock Tech support to see if that plate is available as a replacement. I might try to contact DOB and Edelbrock as well. I can tell you that with the coyote (2011- 18 5.0 Litre) IDX1050 injectors and FIC1000 injectors will not fit in the fuel rail. You have to elongate the bolt holes to the by 3/32" and remove part of the actuator mounting pads to get the rail in and bolted up. They are fine with the standard Bosch type injectors (LU47, LU52) and the idx1050's sit too low to my liking. What did DOB quote you on a larger/better IC?

It’s not a new IC. You have to remove yours and send it to them, then they mod it and send it back to you. $570 plus shipping. I really wasn’t interested in the mod. I don’t think it will improve overall performance that much from the setup I have now. I wanted to pull the intercooler and inspect and clean.
After I received the email offer from DOB, i asked for details on how to remove the IC. DOB said it was easy. It ain’t.
Check with Edelbrock first to see if you can remove the IC from yours. Mine is glued in place and does not come out. DOB didn’t do their homework on this one.

The only mod I can think of to the IC might be to use bigger in / out hoses. DOB probably modifies the 3/4" fittings to 1"..or bigger. A bigger HE might work better...or more airflow through the existing HE.

On the 2005, replacing the oem upper grille with the 9 bar grille ( foglamp delete) might provide for more air going through the existing HE.

On my 2010 GT, with small roush M90 blower, the HE is 18" tall x 21" wide. It gets hit with air from both upper + lower grille. I installed the 7 bar upper grille ( foglamp delete)..and got way more air through the HE. It also eliminated 2 x right bends to the oem 'snorkel' that feeds air into the oem airbox. My 18" x 21" wide HE is the same HE roush used on the TVS-2300 blowers. Both used a 4.5 gpm Bosh IC pump.

The IC extracts the heat...and the HE dumps the heat. Ideally you want greater flow through the IC....and slower flow through the HE..... but you can't...it's all one loop. If you increase pump gpm, you just end up spinning hot water in the loop.

Another possible option is replacing the edelbrock HE, with a bigger / more efficient aftermarket HE, or one with dual fans, or a single big fan. The issue with the fans is.... once the car is going 25 mph, the fans are not doing much, they just impede airflow. They would work good in the staging line.

The 13/14 GT-500 HE is a huge thing at 3 1/8" thick, and 15" tall and very wide, like 21-22".

That’s exactly what the mod is, larger 1” lines. I went with a larger VMP HE with dual fans because I wanted to keep the fog lights with a Davies Craig 150 pump. Works great. IMHO, it’s definitely not worth the $600 for the larger lines. That’s a moot point if the IC is not removable on the early E-Force models.

I'm going to reply to this once because I want the general public to know actual facts and not what some ignorant poster is saying. I only want to clarify. I don't give a whit what the OP is on about. He is a prime example of the 2% of the customers base that as a business you refuse to deal with because they are a complete waste of time.

I posted earlier that DOB was offering a mod to the Edelbrock E-Force supercharger intercooler. I e-mailed them and asked for details on the removal of the intercooler and was told

"It's real easy. Just remove the bolts and pull."

We've done three of these. Yes they took some effort. Nothing a pry bar and one person couldn't handle. Is it possible that EB put way too much RTV in some units and they are harder. Sure.

After talking to Edelbrock Tech Support earlier today, I was told that it is glued in place on the inside with RTV. When they have to remove one in their shop, it takes 3-4 guys pulling on a strap that is wrapped around the front hose fittings. Some part of the intercooler block is usually damaged when it is removed. Edelbrock told me the only time the intercooler block should ever be moved is when there is a leak or some other kind of failure. The intercooler block is where the Edelbrock name is. It doesn't move.View attachment 80755

Taking tech advice from minimum wage goofballs that are good for nothing other than answering phones (this is true of most companies) is not something you want to hang your hat on as the last word. Additionally companies FREQUENTLY over state things in an attempt to keep the lowest common denominator from doing something stupid. Lastly, Edelbrock doesn't have much credibility when it comes to blower design and by extension I would say advice. The E-Force is a design disaster in so many ways it's depressing to think about. I don't know about you (the general public) but I don't put much stock in the advice from people that have a track record of gargantuan failures. I tend to take my advice from people who are at the top of their respective industries. Edelbrock is decidedly not that.


I don’t think it will improve overall performance that much from the setup I have now.
What he thinks is irrelevant because he doesn't have any context to base a conclusion on. A E-Force running at 10psi (low amount of heat) CAN NOT keep IAT's under control even a little with the standard intercooler. End of story. There is a massive amount of data to support this.

After I received the email offer from DOB, i asked for details on how to remove the IC. DOB said it was easy. It ain’t.

Easy is a relative term. In the realm of hot rodding it is super easy. For someone who has very little mechanical ability or desire to improve upon their skills it could be considered hard. If all a person can do is change their oil and put a wheel on a car, yeh, it would be "hard". To even your beginner hot rodder it's easy.


That’s exactly what the mod is, larger 1” lines.
This is not exactly what it is. The IC mod allows the use of up to a 1.25" line. I don't know about everyone else reading this but tend to discount the credibility of people that make bold black and white stamens of fact.....that are wrong. What else are they wrong about?

I went with a larger VMP HE with dual fans because I wanted to keep the fog lights with a Davies Craig 150 pump. Works great.
No, it doesn't work great. In fact, it works like crap. A combination like this can't handle more than 4-5sec of WOT before it starts to pull ignition timing/power.

For everyone reading this if people make claims about IC system performance and IAT's and they are not accompanied by data they're information is completely useless. 99% of the time they don't even know what the data should look like to be considered good.

IMHO, it’s definitely not worth the $600 for the larger lines.
The OP's opinion is one based on profound ignorance.

In closing:

We lead the industry in intercooler system testing and product that works. We have more data to pull from than the rest of the industry combined. We are the only source that can solve most IC system problems. We take great pride in that. we also take great pride in not selling someone something they don't need. Ask around. We spend a lot of time talking people out of stuff. We are of course here to make money. But we want to make that by offering the best solutions matched to the customers specific needs. We are more driven by being the best than making money. Because if we are the best........the money will come.

I will not be checking this thread or replying to it. I don't do internet drama. And I'm slammed trying to get intercooler systems boxed up and shipped. If anyone has any questions feel free to email us at [email protected]. Thanks

I'll go out on a limb here. With bigger 1" to 1.25" lines feeding the oem EB IC...and 1"-1.25" lines in the rest of the loop, and perhaps a bigger capacity de-gas container....and a bigger HE...and a bigger pump, the entire package would come together, with minimal flow restrictions. With greater flow through the IC..and a bigger HE, (on paper) the IC should be able to extract more heat..and the bigger HE should be able to dump the (increased) extracted heat.

I believe what DOB is trying to do is to minimize all the restrictions / bottlenecks in the entire loop, for a max gain, optimized cooling setup.

Let’s be clear here. DOB emailed me first with its offer. I emailed back
multiple times and asked for a detailed explanation on the intercooler removal. Because it ran contrary to what I’ve read before. Here is his reply,
F5FC42ED-BFA9-430C-84F6-79447781317B.jpeg
Because mine is an 05, it has the water crossover blocking the intercooler and requires much more time and work to dismantle parts just for access. Once I gained access, I used a pry bar to the point of safety. It did not move. I used a ratchet strap around fittings and attached to my workbench. It did not move. I tried both. It did not move. At this point, I even tried to wedge a single edge razor blade in between the IC face and the body of the SC by tapping it with a hammer. It was so tight, the razor blade would not go in. https://youtube.com/shorts/o0fbDo474co?feature=share
I called Edelbrock at this point and was told that the intercooler blocks for the early model Mustangs and F150s are not designed to be removed except in cases where they are leaking. And when they are removed, they are often damaged. The RTV goes completely around the intercooler body on the inside so all the air goes through the IC and not around it.
This is confirmed by an old post I was able to find by a fellow forum member “Maypo” , who works for Edelbrock, on 3/5/2020. 0B17E269-081F-4BC1-B7B3-19FA80965EE0.png

Here is link to thread. https://www.s197forum.com/threads/edelbrock-stage-2-supercharger-install.137303/page-3

I
f DOB was able to remove 3 of them with a twisting of a pry bar, then obviously Edelbrock has changed things over the years. This is not a fault of Edelbrock’s. It is a sign that DOB did not do it!s homework and offered a product/service that is not possible on all of Edelbrock’s SCs. I just happened to be the one that found out first. If you think this mod is worth the money, then go for it.

But as I stated above, BUYER BEWARE. You might be replacing the IC.

Good info. Anyone have any experience successfully removing this? I haven't been able to find any instruction(beyond the obvious basic steps) or videos.

WOW, I guess someone should post instructions on "how to change a tire" as well. I mean, do all five of those lugs have to come off? And now that the car is jacked up the wheel just spins, this is SO HARD!

DOB rocks, ya'll stop whining...
