BEGi does it in the rear?
 
So, Corky decided he wanted to take a stab at rear mount on a 2006 mx5. Interesting. Here are the results. (sorry if this is a repost, i didnt see another one)

Good god... say it isn't so.

levnubhin 05-16-2008 09:10 PM

Why not try it if you have the resources? The article does say that the production kit will be under the hood though.

i would hope so. i can't see the intercooler being behind the turbo as a good thing for cooling the charge air. unless you drive backward over bridges in the rain....

I think thats the only thing that kept me from shitting a brick.

Saml01 05-16-2008 09:18 PM

I dont understand. If they plan to put it under the hood why experiment with it in the back? Just for shits and giggles? No ones gonna buy a rear mount, seems like a waste of resources.

I wonder whos soup pot they cannibalized for the turbos heatshield.

It actually looks like the easiest approach to get the thing boosted while you worked on the electronics to manage it. Get the computer up and running, then get the thing to fit under the hood.

Braineack 05-16-2008 10:11 PM

If you followed the thread on m.net Corky absolutely did not want to produce a kit that was "offroad" only. I believe one of his employees just went at it, and now they are going to refine the system.

I had a strong suspicion it was going to be a rear mount for the longest while. Before the -S kit was released actually, which I thought was going to be the announcement of this kit.

Yuck.

I wonder if Kurt Rohmer was on retainer for technical advice...

AbeFM 05-18-2008 12:40 PM

Why the hating on the rear mounts anyway? The only thing I'd realy worry about is cooling of the intake charge on the way down the pipe. The IC in the back of the turbo DOES look pretty suspect to me, in fact, why bother with an intercooler at all with so much piping? Even a tiny water/air IC at the front would get out that last three joules of heat but with 10 feet of piping you can't possibly care. And it would look really stock if you make any effort to do so.

Plus, you could cook stew in your trunk, or really any crockpot dish.

I doubt it,I don't see chicken wire,zip ties and chewing gum holding the turbo & intercoooler on.

betcha the final product will have a front mount and a better exhaust setup.

WTF cares about the NC, I'm more interested in the 99 timing and fuel solution

cueball1 05-18-2008 03:04 PM

If you've got the parts and the time why not try? A couple of years ago Megasquirt would have seemed ridiculous to try. Home built ECU - are you kidding me?

If people didn't try new ways to do things we would still be riding horses and all porn would be in the missionary position.

Just needs a cooling fan, and an extractor trunk.:giggle:

MegaSquirt stand alone? Seems to work well. Plus the OEM ecu makes an okay emergency frisbee in case you get tired of driving your car and want to do something else fun.

A small effort to keep it CARB legal. Can't mess with the CATs if you want to be legal..

Ooooo, I was alright with the turbo in the back thing, but behind the cats? That seems a doomed effort to say the least. Yes, they are mean about letting you move them around (and why we need so many is beyond me!), but you lose all sorts of energy in there, don't you?

how is the final product going to differ from the concept?

TurboTim 05-20-2008 08:53 AM

Looks pretty slick to me. What do I know though. :dunno:

Renesis swap = CARB legal :)

The final one will mount above the current exhaust manifold and will relocate the battery box. At Least, that was the last I heard...
Stephanie

AbeFM 05-20-2008 12:35 PM

And the first five people to buy a kit get a free NC to put it on?

I say the proof is in the pudding.
BEGI's results will tell us the real world pros and cons of rear mounting. (I'm interested in how big the cons really are).

AbeFM 05-28-2008 12:59 PM

Does it in the rear, now he wants to know how big the cons really are? I know a couple ex-cons I could set you up with. :-P
