Before you start reading, this is just an idea that ran through my 'creative' mind lol! so don't flame me for my creativity plz =]

I've seen ppl make their crx's awd using CRV and civic wagon parts.
However, I've done a little more research on that and it is the Real Time AWD which apparently only 10% of the power goes to the rear wheels, and only when it is needed.
(i may be wrong on this, all i did was google/HT this info)

In the USDM, as far as I know, only the Acura RDX's and MDX's have the Super Handling All wheel drive ( SH-AWD).

Without a doubt it is a very unique design for awd systems, but imagine if you stuck that into a crx?
30%-70% of power could be distributed into the rear or front at any time.
0%-100% could be distributed to the left or right sides at any time.

possible?
is it worth it? or would it just be an 'accomplishment' project (not for racing).
What i plan to do is swap the K20a motor into my crx but somehow make it sh-awd at the same time.

 

good luck is all I have to say...

 

you better gett reeeeeeal acquainted with your mig welder and bandsaws buddy. and if you need to ask me which either one of thsoe are.... just stop right now.

 

i hope you are a computer engineer too

 

you'd be on your own. but if you have the knowledge, time, and money to attempt it, i say go for it.

you need to do more research, you are very wrong. Click my sig.

+1

 

anything is possible. anything. it just becomes a question of what is worth time, aggrivation, and gobs of money that you probably wont get back out of it. ever.

 

highroller, how is that awd hatch? you got any performance numbers or mileage yet? looks bada$$!!

 

Almost anything is possible but that would be bordering on stupidity. Go have a look at how the SH-AWD system, everything that goes along with it and how it works and then re-evaluate your idea.

 

You're going to need a lot more than luck.

And if somehow this does happen. Document it and post it up on here. I'm sure we'd all want to see it progress.

i see! so it is possible to attain close to 100% power to the rear wheels with rtawd
however, there is still one thing that's bugging me... hopefully you could answer =]

i've read somewhere that people say the parts are made for racing and they could "snap" if you floored it??

you being the guru, is this true?

here is the link which i read up part of it:
http://www.topspeed.com/cars/a....html

The ECU is what controls the SH AWD and i know that the Acura RDX uses a k23a1 engine.

Not a k20a, but im still in the midst of figuring out exactly what is required. hopefully you guys could help.

once i figure all this stuff out, im serious about this project. it isn't a matter of wasting time/effort. just waiting (for money and labor) =] lol!

The hotter the viscous coupling unit, the more power is transmitted to the rear wheels. That 10% figure is completely stupid.

100% cannot be delivered to the rear wheels.

Why would Honda make a 4wd system that fail's everytime you floor it? Does that make sense to you? :/

The viscous RT4wd system (no comment on the CRV's clutch style system) is a very competent system that i've personally taken places which can often shy larger and better equipped 4wd's. It's performance potentials are greater then the CRV's system, mainly due to the Viscous Coupling unit always transmitting power at all times.

 

Isn't is also possible for the fluid to over heat and lose friction, therefore making the diff less effective?

I've never had that problem. It becomes more viscous as it heats up, not vice versa.

Yes but over time the snot or glue that maintains that high temp uber low viscosity has chemical breakdown and sediment deposits like every other fluid. With regular changes it should be no issue, many cars use a viscous diff with success.

 

Too bad its a non serviceable part then!

so say you were to compare the crv's rtawd to...... say subaru's or mitsubishi's awd systems.
just as good? worse? better?

technically putting awd into your car would put you in another division yeah?

 

really? what a stupid design. Why make a vicous coupler thats not serviceable.... only replaceable..... thats REALLY dumb.

works great, I have droped the clutch at 7500 rpm more times then I care to remember. I have yet to break anything at 11psi. Its currently my dd

No numbers I'm not near a track and even if I was I dont care, its my winter beater. Thats what my eg is for

Look for a built motor and more boost soon

My sedan is awd. The system that's in my car is different to the CRV's system. The CRV uses a clutch to engage drive to the rear wheels, so in conditions that don't register the front wheels as slipping means that no drive is sent to the rear. This is much more of a rear wheel ASSIST system.

Subaru and Mitsubishi's AWD system's are in a complete different league compared to the CRV's system. I believe the CRV's system to be inferior to Subaru and Mitsubishi because of the aforementioned delay in drive application.

 

i have the same idea it hit me about two years ago awd crx one day

 

I believe the RL was the first to have SH-AWD here in America.

It's pretty complicated and the settings are probably already configured for what car it's in.

Sounds like it would be easier to just buy an RL and lighten it.

 

i remember few year ago here in Québec a AWD CRX
