Electric Intake? Is This Just Crap?

if ur talkin about an electronic supercharger all it is is an electric fan that removes any negative pressure in the intake manifold and is apparently not as effective as they say although it will make some difference

they theoretically sound good... but are far far from it

There not even theoretically sound.

These things use a motor that has about 90% efficiency. Charging you battery is ~60% efficient (?). On top of that the alternator is 80-90% efficient and it takes power from the motor to start with. I'm just pulling numbers out of my ass but you get the idea.

ja matt i see your point, but this is when you start looking into practically... and the whole theoretically sound thing too deeply

they are "theoretically sound" as in that they are attempting (and quite badly i might add) to force more air into the intake...

they are theoretically sound otherwise idiots wouldnt be buying them would they?

we all on the same wavelength though.

1000 CFM at 2psi.

fairly restrictive warranty.

I could see it helping - if you have a 1.6L N/A econobox. A little more torque off the mark.

maybe it would help on a 1.8.... how much air does your engine suck at 2krpm? 3? 7?

waste of time on an engine that develops any sort of decent power, and as soon as you are moving, well, there is that extra load. don't forget electrical load is turned into mechanical resistence in the altenator.

Not saying I wouldn't buy one - I just don't happen to have an EFI 1.6 shopping trolley.

EDIT: spelling

I was reading an article on the popular science website where they tested a whole bunch of 'fuel saving' devices and they conluded that the best you can hope for is nothing will happen, one device even set the car on fire :happy: most just increased fuel consumption and decreased power.

Car catches fire, you stop driving it. You stop driving it, the engine stops burning fuel.

System works as advertised. No refunds.

haha, i have been meaning to look into these heard a bit about them iv seen 1 in someones engine b4 not much i know about them. apart from what u guys already know. :(

guy at my work has one on a paseo 1.5. He said it definately does give more grunt but the fuel consumtion DID NOT get better, it got allot worse according to him. Apparently theres simlilar systems for motor bikes that iv heard some people rave about.but thats on a very small motor remember

my opinion on them is that they probably would add maybe 4 ish kw's of power at the wheels on a small motor NA car.Youd be able to only just feel the difference i rekn. I guess if your modding a small capacity NA with cheap bolt on uprgades for a little extra get up and go then it would be ok. On there website they do say that they " work best on smaller engines".

      remote oil cooler hose size, 8,10 or an12?

      By GTSBoy · Posted

      I will rebutt this and the preceding point from Dose....but without doing any calcs to demonstrate anything and without knowing that I am right or wrong. But... The flow capacity of a fluid transfer system is not limited by the smallest orifice or section of conduit in that system, unless it is drastically smaller than the rest of the system. OK, I use the word drastically perhaps with too much emphasis, but let's drill down on what I really mean. The flow capacity of the system is the result of the sum of the restrictions of the entire system. So, to make an extreme example, if you have a network with 3" pipe everywhere (and let's say a total length of only a few metres) and that 12mm ID restriction of the oil filter connection being the obvious restriction, then for any given amount of pressure available, the vast majority of all the pressure drop in the system is going to occur in the 12mm restriction. But.... increase the length of the 3" pipeline to, say 1000m, and suddenly the pipe pressure loss will likely add up to either be in the same order of magnitude, possibly even exceeding that of the 12mm restriction. Now the 12mm restriction starts to matter less. Translate this to the actual engine, actual oil cooler hose sizing, etc etc, and perhaps: The pressure loss caused by flowing through the narrow section (being the 12mm oil filter port, and perhaps any internal engine oil flow pathways associated with it) is a certain number. The pressure loss through, say, -12 hoses out to the cooler and back is negligible, but The pressure loss through -10 hoses out to the cooler, at the exact same length as the above, starts to become a decent fraction of the loss through the 12mm stuff at the filter port. Maybe even it starts to exceed it. I could actually do these calcs if I knew 1) how much oil was actually flowing in the line, 2) gave enough of a f**k to do things that I hate doing for work, voluntarily for a hypothetical discussion. Anyway - I reiterate. It's not the narrowest port that necessarily determines how much it can all flow. It is the sum. A long enough length of seemingly fat enough pipe can still cause more loss than a semmingly dominant small bore restriction.

      To pick up what Dose is putting down. Not a lot of point running a huge hose if the motor is still restricted to the smaller size... It's only capable of flowing so much at that point...   *Waits for GTSBoy to come in and bring in the technicalities of length of pipe, and additional restriction from wall friction etc etc*

      Tein Circuit Master- rebuild worth it?

      Hooley Dooley these things have some history! If i sell them they will need a certificate of providence to prove they have been in the hands of verified RB20 royalty! They have been stored in a plastic tub, away from sunlight and moisture. They are in mint condition. And they will stay that way, as i have sprung the money for a set of shockworks coilovers. I'm just working on getting them in at the moment, after rebushing the rear of the car, and while the subframe was out i welded in the GKtech reinforcement bracing as well.  They will get a workout at Ararat King of The Hill in November. I ran 48s on the short course there a few months ago, and i am hoping with new bushes and shocks in the rear i can launch a bit harder. There was a fair bit of axle tramp when i tried too hard off the line. a few of the corners had dips mid way which also made the car feel a bit unsettled, hopefully this will help there too.

      Food for thought, the stock oil filter thread is a 3/4-16 UNF, which has an ID of about 10 to 12mm (according to ChatGPT lol). Now compare than to an 10AN, which has an ID of about 14mm (Raceworks is 14.2mm, Speed flow is 14.27mm).

      Yep, totally get that. However hooking in for Generator back up is only a few hundred bucks for the wiring. You could put a couple of those in (for different circuits explicitly) and run a couple of baby generators. Bonus, you can balance them across different circuits, and now have backups in your backup. I'm looking at buying places that won't even have water etc, and I don't mind the idea of getting off the electric grid either, even with everything you've said. This country already has enough power outages that even the mains grid isn't that reliable anymore. I do agree though on spending a bit more to get better gear, and to add some extra redundancy in to the system too.
