No clue, but a pain in the ass to keep it on a trickle charger all the time.

The Edelbrock kit taps the EVAP solenoid harness for switched power to drive the water pump relay. I don't have specifics but it is not uncommon for emissions controls to be active at any time, even with the car off. My wife had a leased Scion IQ that I would sometimes hear whirring away hours after it had been turned off. It's possible that some other system that shares the same circuit as the evap solenoid is being turned on. Would have to take a look at the wiring diagram.

Or, you could have a problem with a sticky solenoid.

This may have been addressed before, but has anyone or Edelbrock state what this sc is capable of with a built motor, e85, smaller pulley, headers, etc. ? What numbers are we looking at?

420whp, some youtuber got his engine built with E85 and a smaller pulley tuned by Delicious Tuning

Yeah, I still don't get that build. He kept the stock compression ratio so he can't make any significant power on pump gas due to having to retard the crap out of the timing. If it were me I would have built to 10:1 CR and installed the smallest pulley possible. Different strokes I guess...

You dont, thats why you use E85, because it has a lot more resistance to knock (detonation). Lowering the compression ratio would lower power, as the supercharger itself is pretty maxed out with the smaller pulley. You would lower the compression for a turbo build, where you can just put a bigger turbo and build more boost.

I'm unsure, what his thought process was. Tbh I don't think he really had a thought process all he wanted was a "built" engine to support and join the 400whp+ club. And he got what he wanted.

[armstrom]

I'm fully aware of the role E85 is playing here. However availability in most places is spotty at best. Boost and compression make power in different ways. A high compression ratio increases the thermal efficiency of the combustion process but you are still ultimately limited by the mass of oxygen (and fuel) the engine can ingest. Forced induction raises the cylinder pressures like increasing CR does, but also greatly increases the available oxygen mass to be burned. Yes, in an ideal world you would have the best of both, but that means you must have high octane fuel to resist preignition at such high cylinder pressures and temperatures. If a compromise must be made to run on pump gas then "pound for pound" you'll make more power safely with higher boost and lower compression.
You can only retard timing so far without skyrocketing EGTs.... Of course, you can fiddle around with valve timing to reduce cylinder pressure also, but why not just build the engine with a better balanced CR to start with?

OK, I went and read the post about his setup... He is already on the smallest pulley so I guess if the goal was only big power on E85 the I suppose I get it... But only making 280 HP on pump gas is a bit disappointing. If you have consistent access to E85 then you can treat that power level as a fallback. I would still trade some of that max power on E85 for some more power on pump gas, but that's purely a personal preference. I don't like to run my cars on the ragged edge all the time.

280whp on that dyno is no joke.

A stock BRZ dynos 150ish on it. I'll let you do the math.

420HP is nice, but why? I know people love to quote numbers but in reality, my Edelbrock supercharged car makes 323 at the wheels on e-85. That is more than 200 tread wear 255's can handle off the line. 0 to 60 in 4.9. On the track it's a nice balance between power, traction, and my driving skills. I really see no need for more power my self.

I'm not saying 280WHP isn't a nice number. But when you consider the car is making ~420WHP at the same boost level on E85. That's a big gap for no increase i boost. To me that means the pump gas tune is leaving a LOT on the table just so it can survive the high compression ratio. I would rather have a car that makes mid 300s on pump and maybe high 300s on E85. Again, just a personal preference. Of course, E85 is nearly impossible to find near me so that might have some influence on what I would do with my own car

E85 allows the cr to be used. Pump gas makes tuning a compromise.

Yep, that's pretty much my point. Clearly E85 is the superior fuel for making power. It lets you "squeeze the balloon at both ends" so to speak. But for many people the "compromise" of pump gas is all that is available to them. With a lower compression ratio you wouldn't have to sacrifice so much power to run on pump gas. Yes, you give up some of your maximum power potential when running on E85 but your power doesn't fall off a cliff just because you can't find corn juice somewhere. I mean, at some point when does E85 become a compromise? If I could just run on pure alcohol I could squeeze out even more power, or how about nitromethane? At some point everything is a compromise.

I believe TJ hunt did this and posted to you tube. Unfortunately you have to deal with that, but the data should still be visible with the volume Muted 👍🏼
