While I realize the detrimental effects of an ALS on a cars exhaust and the temperature of the turbo.... (these problems i'm sure i can fix) Is it possible to custom fabricate an ALS system for an h23..... I ask b/c I just sold the engine described in my name for $7,000 and bought another H23 motor w/ a h22 tranny. I have searched all over the place and can't find mention of this anywhere. YES i also realize honda doesn't make an ALS. {The old engine was the h23 block with h22 head bored out to a 2.5 liter...258 whp...... Why would i get rid of this you might ask.... the money was good and the original block its built on has 175,000 miles.... while it runs superb 75,000 of those miles are extremely heavy driving thanks to me. Just stopping problems before they happenWell i think that prevents a good deal of stupid questions and sarcasm directed towards me(I Hope)} I had one person that said it might be possible by routing some of the stuff through the oxygen sensor but that doesn't nearly address all of the ecu issues. As far as the heat induced on the turbo which is generally something unavoidable... A solution i have heard that may be possible to cool the turbo when the ALS is cranked up high like in a prolonged race would involve a timed release of a tiny shot of nitrous directly into the turbos intake. NOS just seems logical i am looking into a wide variety of other compressed gasses for this. (yes i am aware of how crazy this sounds... My cousin graduated from MIT(not bragging for him just explaining so i don't get hazed) and is very interested in helping me with this project... he is drawing up plans for this psycho contraption to cool a turbo as we speak) I am well aware of the costs of such an endeavor before i have them brutally layed out for me. Surprisingly if you know the right people with the right skills custom parts fabrication is not as expensive as you think(and even if it is trust me i have managed to make enough money for this on the last 6 cars i've restored over the past 3 years. Don't hate I just want to build a truly unique car for road racing track applications (not necessary but fascinating none the less). Essentially what i need to know is how to overcome or dance around the ecu. (I know this post seemed like it would never end and i'm sorry for the life story but i just wanted to lay out some concepts and explain how they are feasible for me before I get my head chopped off by some of you guys... thank you for your time)

 

another great idea was just presented to me... freezer coils in an insulated tube as a means of drawing in icy cold air lol
still keepin it psycho lol

 

huh???? so why do u want als? also what do u mean by dance around the ecu? if you mean u want a boost friendly ecu then u could do aem ems, hondata, etc..

 

that sounds like a very wonderful project.

go with the AEM EMS due to it being a complete standalone ecu.

please let us know how it is all going and update with pics. although not too practicle, a damn good project none the less.

put an als on a monster turbo'd h23 and now you have no lag, creating tons of power at all times on a road course. think of the possible opponents.

 

Well, a traditional ALS (a "bang-bang" system) is no more than the ECU retarding the ignition like crazy and dumping a ton of fuel whenever you lift off the throttle. Then a secondary sparkplug(s) located in the turbo manifold ignites all the unburnt fuel that ends up in there . . . . Most stand-alone fuel management systems can do that.

But honestly, that technique would never work on a street car, since basically what you're doing is setting off an explosion just before the turbo . . . . no amount of cooling is going to prevent damage in that sort of environment. Rally teams that have used it found themselves needing to replace turbo manifolds & turbines between every single race stage.

As for other types of ALS's, I'd have to do more reading - the "bang-bang" type is the only one that I'm semi-familiar with.

But I think if it were me I'd take the time and money you'd spend on setting up that sort of system, and use it towards a more expensive turbo (read: dual ball-bearing) . . . . although rigging up a small shot of nitrous that would trigger between shifts shouldn't be too hard. You've just got the hassle/expense of refilling the silly bottle all the time.

p.s. Could you maybe try and use some paragraph markings? It'd make your post a lot easier to read . . . .

By dance around I mean I am looking to set up the als system by possibly wiring it in through the O2 sensor. Will the ECU in the car detect this and affect the way it runs.
Also good call on the paragraph markers sorry bout that. In reply to another question I am looking to do ALS to eliminate turbo lag.
New question... is it possible to detonate the unspent fuel some where outside of the turbo?

you could put a sparkplug in the exhaust, f&f style..jk,lol

but why bother, once its past the turbo just let it spit out the back

 

from reading all the previous posts i think if you want the extra fuel to power the turbo you're going to have to do it in the exhuast manifold or the turbo.

doing it afterward will just make fireballs come out your exhaust.

that would be really tyte if you make fireballs come out your exhaust.

go for it man.

exactly...im just short worded today

 

they did it on the EVO in Initial D. (bang-bang system)

 

hahaha bang-bang system. thats a really good name for it. sounds dangerous too.

does that system decrease the car's reliability in any way? cuz it sounds like it would.
