Edelbrock E-Force Troubleshooting Manual

[Burkey]

Is this something that had to be considered during initial tune or does same logic apply regardless of who tunes it? I would probably be more worried about going for more boost but I’m this case I think I’ll go up to the 3.25 on my 2300 soon to “be safe”

Mate, don’t overthink it. I’m running a 3,25” on my 2650. You’re safe enough on that same size pulley with the 2300 you’re running. In fact, I know of plenty of guys running conservative tunes (including Lund) here in Australia on their 2300 units using either a 75mm (2.95””) or 79mm pulley (3.10”).
Just keep good quality fuel in it and you’ll be right. Read: avoid your local United servo.
We don’t typically suffer from the same fuel quality variation issues that they see in the US.
Stick to BP/Shell/Caltex you’ll be fine.

I just bought the 103mm TB, I wasn't aware of the Kong Unit's compatibility.
EB's TB is getting rather expensive, But I believe the real gains from going larger than 103mm is probably going to be made at big boy boost levels.
I'm starting a few projects for this community, I am working up a few designs on Solidworks, and hopefully I can get some working prototypes to test out before too long.

I was going to go with the EB throttle body also but the price is almost the same so I might as well go Kong.
Interesting. Keep us updated when you come out with something.

I'm working on some adapters, a bigger better metal surge bottle and a few other things. I'm still stuck in Italy so I have some free time to mock design stuff until I get back home and get the actual parts in my hand so I can finalize a piece before I have them sent out for cnc.

Another area I felt we have a gap is the intake for us that went stage one but have a bigger TB. Covid19 got me screwed up. I've had these ideas since last year but I couldn't move in them with all that's been going on.

Thanks Burkey I do overthink these things since it’s my first modded car haha. Just want to ensure it’s safe since I’ve seen the debate about smallest pulley on pump fuel etc.

Stick with the 3.25”. You’re already well and truly safe enough on that pulley. If the engine were to let-go at that boost level, it probably wouldn’t have survived with less boost anyways.
There are plenty of people pushing stock engines MUCH harder than you’re asking of yours.

My 2300 came with the 3.0 pulley so I have that. I was originally asking if there are issues going to a 3.25 just to keep it safe or does it generally need a re tune due to less boost

So I just started getting a whine from my supercharger behind the pulley. I'm guessing it's the bearing. Increases with RPM, used a stethoscope to pinpoint it although it's pretty loud. Anyone had this issue before? Is that bearing easy to replace?

Are you referring to the S/C pulley? Whether that or the others, its easy enough to bench press an old bearing out and press a new one in. Get the bearings at an industrial bearing supply warehouse.

Yep, the bearing just behind the pulley in the SC. Talked to edelbrock and they want the entire head unit shipped but also mentioned that could be risky and cause more damage. Probably just going to have a friend press it out and replace it.

Per Greg at Kong Performance, they have a CNC porting program for the Coyote Edelbrock head unit and see 60-100 whp gains with supporting mods. It's not advertised on their website yet, but they have done "quite a few".

Porting service is $1275.

There’s a sweet upgrade and a new bearing to boot! Unless Edelbrock is doing it free, there’s what I would do!

I know People that have done the porting with great results - not EBs though.

 

[aleccolin]

Hm, what's up with the bearing you speak of? QC issue from EB?

If that works, cool. But for the rest of us without a buddy resource, did Edelbrock say to ship the whole blower? Guess warranty, so a shop would do?

Are you guys still interested in a aluminum surge tank and a billet cnc adapter plate for the Whipple 127/150mm roval, and the Kong 112? I'll design and prototype one if someone has a throttle body available for me.

Yes and yes... bonus points if the TB can be used on Gen 1 coyotes .
