Twin Electric turbo setup

[Accordtheory]

Great minds..or at least those unlike Hauntd ca3's, think alike.. I can't believe how dense that fucking guy is, what, does anything that makes sense just bounce off the side of his head?

[AccordEpicenter]

makes me love it when noobs have no idea wtf is going on

[AccordB20A]

all i can say is lol

and all that shit you guys are stressing about just went in one ear and out the other
well i mean in one eye and out the other...

[HondaBoy]

well seems like someone is thinking of only pushing air and forgot about compensating the fuel. hmm. good way to burn up the cylinders. haha, electric superchargers. and thats because i know which ones we're talking about. not even the roots type, just a marine use one. those are crap!

[AccordEpicenter]

those things dont actually build boost. You might get .01 psi boost, they dont really do anything. A leafblower duct taped to your throttle body will do more good

[Soopitup]

Ya I now have more than enough information to throw that idea in the trash.... and that was a pretty nutty off topic arguement there...lol, good stuff..

[ghettogeddy]

ive been thinking of a belt drivin sc for a while and would easly be mounted were the ac is at just getting it ligned up right and the charge pipes installed being the prob

i am actually planning on something like that in the not so near future. Dont flame me for wanting to supercharge, its just something about being unique

[turabaka]

Nothing wrong with superchargers. At least you don't have to worry about lag then.

[Hauntd ca3]

hey
i may have got shit wrong but how bout correcting me and teaching me something
instead of baggin me
i'm a mechanic, not a speciallist
have to know bits bout everything
not lots bout 1 thing

[2drSE-i]

im afraid one of his pet peeves (ive been on the receiving end of his anger once or twice too, haha) is people presenting mis-information as fact. That is one of the reason for so much ignorance on this board tho.

[Accordtheory]

I'm done talking shit..for now anyway.
here's something useful instead, a link to a post on honda-tech about superchargers. I haven't read the whole thing, but there's some good info in there.

superchargers arent bad, but i went turbo because youll make more power due to the greater efficiencies of the turbo, and boost is easily adjustable, but any forced induction is badass, esp since na power in an a20 is hard to come by

[Accordtheory]

did you check out that thread? I don't think the dude has implemented it yet, but I'm pretty sure he will at some point. I would prefer a supercharger if it could make my motor feel bigger, like a 6L vtec, with instantaneous power everywhere, but I haven't seen that yet. The car that had the lousiest powerband of any car I've ever driven was the pontiac gtp, eaton supercharged 3.8. Even the ghey ass g6 would kill it. Not really impressive off idle, huge % increase in midrange, like a turbo, then faceplant. No power over about 4.5k. That same motor cammed and with i/h/e would beat that supercharger badly. With a centrifugal compressor (procharger, vortech), the boost would rise with rpm, opposing the natural reduction in VE with rpm, which would result in a really nice powerband. But, a turbo would still beat it once you reached the limit of the fuel you're running on, since the turbo wouldn't be taking as much power away. Turbos really do rule, it's the closest thing you'll ever get to having a jet engine in your car.

ive just always liked the idea of a supercharger on an A20. With the stock midrange being one of my favorite things about this car (not really honda-esque is it?) i just thought id like to stick with it.

[2drSE-i]

that thread is pretty cool, but i wa more interested in the centrifugal crowd of supercharging. The A/C location wasnt very appealing to me, just way too tight. I was, though, considering relocating the PS pump to where the ac is now, and having a custom shaft made to reach from the left side of the engine bay (as you see in many centrifugal B series kits) to where the PS pump is. It would require, similarly, a custom crank pulley. Unfortunately, the Rotrex superchargers (the ones i was most interested in) also spin at CW. So these, too, would need to be keyed to CCW. This is all hypothetical at this point so i dont really want to make a thread at this point in time, because no real progress will be made for ....oh say 3-4 years. I have a lot of other projects in mind ahead of this one.


EDIT: ok i just caught onto the basis of centrifugal S/C's, and they too catch peak boost at peak RPM...so they arent really what im looking for.

[Ichiban]

You guys should run the Detroit 6V-71T engine.

It's turbocharged, and supercharged!

And diesel!

And a two-stroke!

[Accordtheory]

That was a very productive contribution, guyhatesmycar.


I'm still down with my plan of putting a turbo so huge on my motor that it basically becomes a jet engine.

[AccordEpicenter]

problem with centrifugal superchargers is they only make peak boost at peak rpm AND they do have a bit of lag compared to a positive displacement type supercharger, like a roots blower. and yes i looked thru that thread a lil. I like detroit diesels but i also like cats, particularly 3406's 3408's

[2drSE-i]

i do prefer the diverse mounting locations of the centrifugal type though. I just don't like the idea of using a custom manifold with my supercharger...id rather just run it through an Edelbrock Performer X

[Accordtheory]

It's all just a series of trade offs. If I was an oem engineer in charge of building a high powered, yet nicely driveable street car, I'd use the centrifugal setup. Like I said, the linear increase in boost will compensate for the linear reduction in VE with rpm, resulting in a really nice powerband. You might not get 330+ ft/lbs out of the a30 at 3000rpm, but you'd still get 400hp at 6800..what do you guys think? Esp with a little more cam, intake, exhaust, etc. 400hp at 6800rpm is only 308.9 ft lbs. But I'm talking about at the wheels, so It'd have to be a little more..but still doable

[AccordEpicenter]

anything is doable with time and money, but yeah, if you were going for driveability, a centrifugal setup would prolly be a much better choice than say, a big turbo, but for pure numbers, the turbo would win out

[Soopitup]

wow I am impressed on the huge discussion this post created, interesting stuff

[Accordtheory]

yeah. Either way, I want to have a say in it. Whatever, motherfuckers might tallk about my dick size, but I don't give a F. I know I can school mutherfukaz left and right. Yeah.
accordepicenter, you got my back, homie? yeah..what now, bitches?

that actually sounds like a good idea
has anyone thought bout super and turbo?
i think nissan done it on something a while back
think they called it the march super/turbo
think the march is a micra sized thing
would be interesting to see how that would work
