Nothing new from Edelbrock. The HKS unit has some promise, FAB9 has one install working on ND2.

Just made it through every thread of this page. Good read.

Were there ever any dyno tests with ND2 exhaust mods? I've got the header, different brand mid pipe, and super q. Wondering if there's significant power on the table by switching to a monster resonator like the magnaflow posted a few pages back then a straight style muffler.

The dyno we used for more than a decade closed when Covid started and has not reopened. I expect any highflow midpipe of similar diameter to perform similarly for a normally aspirated ND2.

Good notes and update from customer Nathan Duke:

I replaced my SC due to a bearing failure recently, and ever since then I was seeing IAT2 temps, AKA boosted air temps, 90°-100° above my IAT1 temps. I thought the intercooler may have been gunked up. I took everything apart to replace it but the IC looked fine. I went ahead and put the new one in since it was already apart but I also looked at the rest of the system for potential issues.

The BPV was only opening up about 25% the way that Edelbrock had set it, so I reset the arm to open to ~80%, just shy of 90°. Edelbrock must be setting them up super tight these days. That means a good bit of air is still having to go through the rotors at light throttle which will create a ton more heat. I put the car back together and it had dropped my steady state 75MPH cruise to only 40° higher than IAT1. That’s a massive difference in power. Pictures of the BPV adjustment I did using my broken SC to demonstrate. The one with it barely cracked is where it was set from Edelbrock. My setting is the one that’s almost at a 90° angle. MPG increased, IAT2 dropped by 50°F+, and the car feels better all around. I did have to add a restrictor pill back into the BPV after increasing the travel because it caused a surge at light-medium throttle right on the vacuum/boost threshold. I tried a .050 restrictor yesterday and it’s almost perfect now. I ordered a .025 to try and I bet that will get it back to being 100% smooth again. Just a heads up in case any of your customers come across something similar.

The .050 restrictor was so close to eliminating the surge and going .025 was a bigger leap than I thought. The .025 fully smoothed it out but also shot my IAT2 way back up. So, the valve isn’t opening fully with that small of a restrictor. I just ordered a .030, .035, .040, and .045. I’ll figure out the right balance and let everyone know ASAP.

The .045 restrictor has my IAT1 to IAT2 delta at 75MPH cruise between 47°-60° with around 50°-55° being the most common. Ambient temps are 110°-112°F today. The smoothness is solved for my particular setup. If I have the radio off and focus, I still notice the surge very rarely. With a louder exhaust setup it may be more apparent, but I’m good with it on mine.
