Dyno'd yesterday with the Edelbrock E-force installed

Daves1SS · 10-09-2016, 09:44 AM

****UPDATE/CONCLUSION on page 3*****

To say I was disappointed is a huge understatement. This was with the Edelbrock canned tune that Edelbrock said needed no changes after I sent them some scans. The car went pig rich with each pull, and was averaging 10.3-10.6 AF at the tailpipe. They T'd into the boost bypass actuator line to get boost readings, and it showed the boost readings all over the place......like a rollercoaster.....and at one point up to 11 psi boost?!? This is with the stock pulley they sent on the blower. The car has NO other mods aside from a catch can. What on earth would cause that?

This was on a dyno jet with SAE correction. Same dyno that I dyno'd on when I was stock.

Stock: 404 whp, 408 wtq
1st pull supercharged: 503.85 whp and 445.65 wtq
2nd pull supercharged: 497.54 whp and 497.77 wtq
3rd pull supercharged after leaving a leaf blower blowing on the top of the SC for 5 minutes: 515 whp, 511 wtq on a 10.3 AF and boost jumping all over the place.
You can overhear towards the end of the video folks saying it looked like a diesel out back blowing black smoke.

There was a guy there with HP Tuners that hooked his laptop and scanned the car on the 2nd and 3rd pulls. He said peak KR was 3.9 degrees pretty much right before redline. IATs were high but came down to 134 deg F on the final run.

He is going to email me the scans in excel format today, and I will send to Edelbrock and ask them what in the world is wrong. The boost jumping around is obviously a concern, but also that AF is just stupidly rich.

Video, and sorry it's so long. I wanted to get all the commentary from the guys there. https://youtu.be/3QZpSNiZeuc

wow, doesn't sound good, hope they get it sorted for you

I'm sure they will. They have always been great to deal with. Just didn't expect these results for sure. It still feels nice on the street at least......

Catilyst Overtemp Protection may have been a factor. That has been problematic on the dyno, but is rarely seen in road driving conditions. It will cause your car to run considerably richer when enabled.

Wow Dave, sorry to hear that! No doubt there is something wrong with the installation. Go check out my graphs at the bottom of the page and you can see what the AFRs are suppose to look like. Notice that they take a small dip at peak torque and smooth out to a nice 12.5 AFR at the tailpipe.

One thing for certain is that they should not be tapping into the bypass actuator for boost reading. Edelbrock is clear on that. They can pull boost level through the ECM with the SCT tuner that came with the kit. First thought is to have them re-flash the ECM and re-check all of the connections. Clearly the ball is in the installer's court to get it right.

What was their response to this result? Are they in contact with Edelbrock? Take my thread back to them and you can show them what the graphs are suppose to look like.

Even on the very first run when the car was nice and cool? The car wasn't cold per say, but had sat for 3 hours before being put on the dyno and pulled.

Ed, the dyno guy is the one that T'd into the boost bypass actuator vacuum line to get a boost reading, not the installer of the SC kit. I don't have a boost gauge in my car. I didn't know to tell him any differently. I went over all of the connections after I first got the car home after the SC install and that's when I discovered the pinched bypass actuator hose that i then replaced. But everything else that I saw looked fine. I'll be emailing Edelbrock to see what they say about my results.

I could take it back to the installer, but wouldn't know where to tell them start trying to figure out why it is running so crazy rich. So we will see what Edelbrock says first.

Bad gas? Belt slippage? Were the IATs monitored?

Gas has always been Chevron 93 and no reason to think it's the fuel.
There's no evidence of belt slippage either as there's no belt dust anywhere to be found. The IAT's were in the 150's on the first run, the 160's on the second run, and the mid 130's on the last run.

That does seem strange. When we did our COT testing it was at WOT up an 8% grade for a very extended time. So I'm not sure what that would translate to on a cold dyno pull.

I do know that it is a calculated temperature though. So while the actual catilyst temp could be 1400°, an unknown data error could be reporting a temperature of 1700°+.
I hope you get it dialed in.

laynlo15 · 10-09-2016, 07:44 PM

Dave, hope you get it straightened out. Should make at least 550. Keep working on it

Daves1SS · 10-09-2016, 09:08 PM

Thanks for the input guys. Will let you know what we discover.

So as a side note, on the way to the dyno, I had been driving very aggressively next to a new corvette on the interstate. Perhaps it stored a high catalytic temperature from those sprints regardless of the fact that the car had cooled for 3 hours+ prior to the pulls......

Still waiting on the guy that scanned my car to email me the logs before sending to Edelbrock. He didn't send them last night like he said.

Here are the dyno charts:

Atomic Ed · 10-10-2016, 09:05 AM

Maybe it's my inexperience showing on dyno runs, but those AFR curves look suspect to me.

Have you messed around with your SCT unit much? If you haven't done it already, go to SCT's site and download the LiveLink Gen-ll software and do your own measurements. Or, I also use Torque Pro for Android with a USB connector in the OBD port.

I think it would be a good idea to confirm the numbers yourself. When you get your friend's data, you'll then have a three way comparison.

Hang in there Dave. The bright side is your about to pick up an additional 50- 75 rwhp soon!
