Edelbrock E-Force Troubleshooting Manual

[CraigJ]

I have the GT350 on mine and made slightly more power than an identical car that had the 90mm.

save money and buy the GT350 imo.

palm beach dyno tuned.

How is the driveability? I’ve read the 87mm is very difficult to tune.

I will likely be Lund tuned, but haven’t ruled out PBD. Not sure if Lund will tune the 87 though.

No issues to write about. drives fine.

What kind of oil separator setups are guys running with the 2650 kits on 18/19 cars? I was going to go with the UPR dual can setup specifically made for the Edelbrock, but I saw a post on here that is was a garbage kit considering it's $400 price.

I was thinking about just doing the Watson/peterson breather can to the valve covers, and just capping off the intake/TB side ports. I see a lot of the race/turbo guys going this route.

I'm using the UPR you mentioned. Clean install as you can see in the picture. At least it looks impressive.

I have no idea how well it's working though. Palm Beach Dyno can't seem to get my part throttle jerking/bucking fixed and they have stopped responding to my emails. I spend so much of my time on the car data logging and installing new tune versions that I don't have time to bother with anything else...

Good stuff, I may just go with the UPR kit and hope for the best then. I know I will need some type of can setup once I go E85.

Don't get me started on PBD. Rob is tuning for my setup as well and I am having the same issues. Part throttle and daily driving is awful. It's odd because there are other guys on here with the Edelbrock kits and PBD tuning that claim the car drives butter smooth.

Rob quit responding to me a few weeks ago. My email correspondence to him is courteous and professional, perhaps overly so, if that's even possible. I don't know what the numbers and/or percentages are, but there are other PBD tuned 18-19 Eddy 2650 cars on this forum and various related Facebook pages that are still having the exact same problems that we are having.

I'm beginning to wonder whether or not some of our kits have faulty bypass valve assemblies. I haven't contacted Edelbrock Support, but it's on my list of 100 things to try to do this week...

Off topic, did your 91oc PBD tune put down 691whp? If so damn, I need to dyno mine out of curiosity.

On topic, I also think it's a possible mechanical problem, but I can't trace it if it is. I first tried running the supplied Edelbrock tune, and the jerking/bucking was so bad the car would go into limp mode. Car was undrivable. Edelbrock told me none of their other customers were seeing this. They couldn't help me so I just went with PBD. Now it's better than it was, but the PBD is far from good in my eyes. The fact that both the EB tune and now PBD tune are having the issue, I almost thinks it's mechanical.

Did you take the nitrous jet out of your bypass line? I did. I could try to ask EB for a new bypass, but I don't they would do that or even want me to install that myself. I know their instructions are pretty adamant on NOT touching the bypass in anyway.

Rob is still sending me revisions, but I need to ask twice, and they are taking 4-5 days to get replies. And the revisions aren't really helping much with the jerking/hesitation. I think he may be out of ideas but doesn't want to say that. I want to switch to Lund since it seems like he has these blowers dialed in a lot better, but I'm afraid it is a mechanical issue and I'd just be wasting more money on tuning.

Funny, they told me the same thing. I ended up going with a local guy and a dyno tune and the jerking is gone. I wonder if it’s because these guys are used to tuning the twin bore throttle bodies and the EB uses the stock...?

Anyway, if it’s mechanical you should be able to see something happening on the boost gauge. Based on my experience, my guess would be it’s the tune.

691 was legit. SAE correction factor. I'm at 5500' altitude. I've heard that SAE correction becomes less accurate above 3000'. I did "port" my stock airbox by removing the carbon filter and smoothing out all of the plastic bosses, ridges and casting flash. I also opened up all of the individual grill squares at the airbox intake opening.

I have the nitrous jet still installed. Seems to make no difference either way, in my case.

I've had to ask twice also, more than once. For my latest request, he didn't even answer the 2nd time. I'm not asking again. Three requests is crossing into begging territory for me. I'm not paying to beg...

Are you going to try and push for any type of refund, maybe at least half? Or you just going to cut your losses and go with someone else?

I don't know yet. Still thinking about it. I'm going to do some work on my own to totally eliminate any reasonable possible mechanical issue as an excuse.

If it does indeed turn out to be the tune, I'll probably let PBD know. I'm not asking them for anything again though. I've done that too much already. Of course, the only way that I will know that it's a tune issue is by finding a tune elsewhere that actually works.

One of the reasons that I suspect a mechanical issue is a possibility has to do with a manufacturing defect in my Edelbrock kit. The holes in the passenger side fuel rail brackets were off a few millimeters. So, either the related holes tapped into the supercharger housing or the holes drilled into the fuel rail brackets or both were slightly off. My local tuner discovered this when he bore scoped the alignment of the rear bracket and housing holes. They were off far enough that the rear injector would leak at the top when the fuel rail bracket was firmly fastened. The fix involved drilling out the rear bracket hole larger and using the drill bit as a routing tool to slightly elongate it as well. Cost me $400 in labor to diagnose and fix. My local tuner took bore scope pictures and pictures of the fix and sent them to Edelbrock Support. Their response was a reminder to ensure that the holes aligned up, before fastening the fuel rails. Basically a non answer answer. No acknowledgement of the defect. So, based on my experience thus far, mechanical issues are still a possibility.

This quit being a fun project for me very early on in the process. Lol...

Lund tune definitely drives smoother than PBD on my car (2650/103mm TB/Manual).
I really feel that Rob needs to see several of these combos, (and other combos) up close and personal to get them dialled in better (Eg. Actually take the car for a drive). I’d take my car there myself but it’s kinda tricky from here in Australia.
Honestly, I feel like his tune is worth it for the extra power it delivers, but my “issues” aren’t significant, just frustrating at times.
Seems to me that Lund have become a little shy when tuning boost and “not ethanol”.
If Lund would apply the same spark strategy that PBD do, I wouldn’t even bother with PBD. Unfortunately, they won’t and I fully understand their reasons.
From what I’ve seen in my logs, Lund have the fuel trims around 1%. PBD is more like 3-6%.
Lund have the IAT sensor reading what I believe to be the correct temps. PBD don’t. It’s not possible for the IAT to be below ambient and yet that’s what I see.
No idea how an auto might vary the equation.

I think autos are a lot tougher, especially the 10-speed. So many additional parameters...

Does PBD alter the shift pressures etc on the 6R80? I currently have Lund NA and his shifting is great!

I’m still in the debate between PBD or Lund for my EB.

Burkey’s done the testing... toss up. Smoother or a little more aggressive?

I want smooth. But I also want the little bit extra aggression. BUT, I really like the firmer shifts!
