Edelbrock E-force Owner's thread and FAQs (Frequently Asked Questions)

Hi all,

Longtime lurker here, and early adopter of the Edelbrock s/c, installed November of 2015 with 9k miles on the car. Have had a long road, but finally here, I think. A bit of the story of the car:

- Driving home from official approved Edelbrock installer, the s/c seized. Car towed back and Edelbrock sent out new s/c unit. Reinstalled.

- But from the beginning, car suffered from significant jerking/hesitation/stumbling problems at partial throttle starting from a stop. Puzzling as it seemed no others were having these problems. In reading through all 190 or so posts on this thread over the years, though, it seems that slowly others started reporting similar behavior (86fun, lunatic, sargy, clayrush, B_T, BigFatLip, Luftwaffel, shiumai, etc.).

- Relatively soon after the install, I switched to the Delicious tune hoping it would improve things. It was world's better than the early Edelbrock tune, but it did not solve the hesitation problems.

- In trying to troubleshoot, went through all of the following:

Smoke tested, and all possible vacuum leaks addressed
- MAF O-ring found to have leak and replaced with O-ring from CSG (check this!! improved, but did not completely stop hesitation)
- Edelbrock bypass actuator found to have leak and replaced with new part from Edelbrock (check this!! improved, but did not completely stop hesitation)
- intake manifold gaskets replaced at the time bypass actuator was swapped (did not improve hesitation)

Hardware
- added Delicious D box (did not improve hesitation)
- installed revised Edelbrock MAF air flow straightener intake housing (did not improve hesitation)
- MAF sensor cleaned with MAF sensor cleaner repeatedly (did not improve hesitation)
- MAP sensor replaced with new Bosch part (did not improve hesitation)
- throttle body replaced in case it was the TPS sensor (did not improve hesitation)
- added grounding kit and did Big 3 since I have an 1100W sound system (actually did help significantly with hesitation)


Throughout all these, the hesitation on light throttle never went away, but seemed to lessen very slowly over time. In addition to addressing the legitimate problems (O-ring, bypass valve), I think it was constant refinements by Zach from Delicious with flash tunes done by remote logging. With these, the jerk had been reduced to a slight stumble (especially with the V22.0 Delicious tune). By this point, I had 42k miles on the car!

Finally having gone through all of the above, and with stars aligning for me at work to get the free time, had the car dyno tuned at Mann Engineering in Santa Clara, CA a few days ago.


Results are attached.


2015 BRZ Limited, 42.5k miles
Edelbrock s/c
Ace Type 350 header
Milltek Secondary Catback (Resonated)


This tune was WITHOUT a D-box, since my early unit was malfunctioning. Delicious will be replacing it, so hopefully may get another 10 peak horsepower or so once it's in.


No more hesitation. Car is smooth, quiet, and powerful. On my stock BRZ with my mixed driving commute, I was getting 28.5mpg. With this tune I am getting about 30mpg.


I just want to thank Gary at Mann for amazing service and an incredible facility (with a Maha dynamometer). Likewise thanks to Bill and Zach from Delicious. I could not recommend these guys more strongly, for sticking with me through countless emails and ten remote tunes, and delivering in the end with an in-person dyno tune that solved all the problems. All in all, was it just a tuning issue? Not sure, as there were some hardware issues, and it is still unsolved as to why some cars do not respond well to tunes that work great on other cars.

At this point, don't much care, as I am finally truly enjoying my BRZ.

Excellent news! What did it cost? Did you even need to have the preprogrammed Delicious tune to get this done?

No, it won't be based on the DT tune.

Throughout my entire journey with the edelbrock supercharger, I've had terrible fuel economy. Right after install, with the Edelbrock map, I was getting 17 mpg; down from stock 29 mpg. After two revisions of the delicious tune, I'm averaging 21-22 mpg with mainly highway driving.

I've also noticed that my engine will stall randomly while shifting to neutral coming to a stop. I can't leave a laptop in the car for every drive so it's tough to log however, it happens during the winter months before the car has warmed up.

/sigh - hopefully I'll get to where you are someday.

taiguy, your symptoms sound same as what I had. At partial throttle/tip in, engine would just cut out then over-rev as if to compensate, resulting in jerking down the road.

I did a fair amount of trouble shooting on my own. The debate was always do I fix it myself, keep trying to solve it, or take it in for a tune.

To me it made sense to find out what was wrong with the car first.

In retrospect though, I kind of wish I had just saved up and gone for the dyno tune earlier. I was so down on my car for a long period of time, that I missed out an a lot of enjoyment I could have been having.

Especially with the fuel economy issue, it might make sense for you to just have a dyno tune and troubleshoot if necessary at the same time in order to accelerate the process of getting it fixed so you can enjoy the car.

Best of luck.

It wasn't cheap. Give Gary a call at Mann to get pricing. But it was worth always debating whether to get rid of the car or not. Now I plan to keep it forever.

I did get the flash and go tune before the dyno tune. I don't know if that was necessary or not. I do know that of course they started with the latest Delicious flash and go tune and tweaked it from there on the dyno.

So if my car is stock with an edelbrock S/C, Delicious tuning flex fuel kit and a touring86 exhaust, I should be in the 350whp area?

You're going to need the Edelbrock SC, minimum 2.5" AftermarketFull Exhaust (Catless Header definitely or a quality make HFC header), Flex Fuel E85 kit, higher boost pulley (minimum 3.00" or 12psi+), and the best tune you can get.

With the route I'm going, I'm doing everything I mentioned above minus the Flex Fuel E85 setup. I'm expected to be somewhere between 295-315whp with this setup on 92 octane running the Delicious Tune.

Thanks for that!

Then how did CSG get to 350whp with just the Edelbrock S/C, E85 and 86touring exhaust?

Didn't think I would need the higher boost pulley for this power level according to the Dyno chart provided by CSG. Maybe I'm looking at it wrong?

That's a good question for @DeliciousTuning to respond to. Our 2017 Subaru BRZ was simply dropped off at DT as a developmental test mule while we provided the logging, validating, and feedback for them to work with before, during, and after dyno tuning sessions. The 2017 Subaru BRZ had the following:

Edelbrock 1556 S/C
DT Flex Fuel Kit
CSG Touring86 Exhaust

Tuning was performed on straight ACN91 Octane which achieved about 260whp on the DT dyno. DT was able to get around E70 filled into the tank which was able to pull an impressive ~350whp. Both DT and CSG are still a bit shocked on the number, but alas, the real world validation was smoking a few exotic individuals for science...

Who did the original install? That is the first SC I have heard of failing like that.

Now if you'd just release the '17+ kit.... :P

You guys better hurry before I blow my savings on something silly like a house down payment.

We started from the final revision you and I had left off with remotely, and Bill worked from that point to further refine on the dyno. Your car was a bit off an oddball, but we've taken what we learned on the dyno from yours and that will be applied to our remotely done Edelbrock tunes in the future as well.

Cheers,

Zach

If that setup is good enough to smoke exotics on the tracks, then a full catless exhaust enhanced 12psi Edelbrock SC on 92oct + Delicious Tune should make even 5.0 Mustang drivers wet their pants on the straights!

P.S. Which is what I'm trying to do!

While we are an Edelbrock authorized dealer and installer, only Edelbrock can officially announce the release of the 17+ kit.

With more boost comes more responsibility.

I just noticed.. Did this car not have a header on it? It looks like the touring exhaust on your website is just cat back.
