1994 Mazda MX5 Supercharged project.

Your right its a lifting eye, i have wonderd about using somthing like a bit of angle steel and bolt to the front 2 bolts on the charge to that point, i need to check the alignment to see how they line up.
Airflow out the charger will be tricky. Not really enough space to turn it more than afew degrees. The exhaust manifold drops down quite quickly from the head so i hope the charger is far enough out that with the right shaped out put pipe it will clear and come out nice and smooth. Hopfully the intercooler will deal with some of the heat thats transfered. I'm going to wrap the manifold and add a cover or somthing on the bottom of the charger to reflex some heat.
Next step is to spend some time moving things around in the cars engine bay to see where things will fit. Hope to have a look at that this weekend weather depending.

What sort of shape out put do i need is it best to have the out put a as close to 90o to the bottom of the charger?
I want to put the filter in the top right hand corner of the engine bay with a box around it with a feed from the scuttle area to make use of that high pressure bit. (Blame Andy Bower for putting ideas in my head. but not telling me the propper names) then a 90o swept bend in to the charger.

Price. i don't have 2k to spend on a car thats only worth 2k in the first place. But wheres the fun in buying it, wouldn't learn anything then. Have the fun is building it.

To be honest you want to avoid 90deg bends at all costs due to pressure loss over them. You sure you can't get creative and lean the charger over so exit points at front left wheel centre (I think I need to go do a drawing of that don't I!)

That way you could have a couple of 30 or 40deg bends down the the front to your intercooler - I'm sure it's at this point that Dom will point out an air/water charge cooler would be a much better idea as it will limit your pipe runs and give you a bigger thermal mass to dicharge your heat to. Then you'd control the cooling water pump off an rpm signal and inlet charge temp sender so that you'd get increased cooling when you get temp spikes/higher charger speed......

I really should build a system myself to put these idea to work rather than just theorising shouldn't I!

Anyway even with an intercooler it'll be better than a Jackson kit or the numerous turbo kits out there all of which don't seem to use an sort of post charger cooling at all! I mean come on a turbo feeding straight into the inlet in this day and age, especially with such a huge opening in the front of the car too, no wonder the engine needs no calibration changes, the increase in volumetric efficieny will be pretty limited due to the low air density - ok that my rant about over priced badly designed charger kits over!

And a thread that might be interesting, escpecially as he's getting to the point of making it all fit - www.turbosport.co.uk/showthread.php?t=103350 (and no I'm not thinking I should have kept the charger for myself and done this to the escort.....honest......though it would be cheaper than those shiney cams.....hmmmmm )

So angle charger, and then brace bottom to exhaust/lifting eye and top to a few rocker bolts. And braces are filleted to increase stiffness - hope that makes a bit more sense

no chance of clearing the bonnet never mind the strut brace.

mite just about get away with somthing like this. stole the head drawing you did. sorry. arn't we b
oth masters of Paint.

what car inst begging for more power haha

Done alittle more this evening, following advice from Dom and Andy, i've made a start on a bracket to bolt to the head lifting bolt. the idea is it will be welded to the base plate the charger sits on and with a tab of some sort bolt though to the head.




I need to cut the profit of the head out to get the charger to site close to the head again, but unit i decide if i can angle the charger i won't.

Been out in the rain as well and took some picy of the engine bay to give you guys a idea of the challange it will be fitting it in.



the air filter will end up in the top right hand corner, the air box will come out and i'll probably replace it with on of the closed in cone filter and a cold air feed.




The charger has basicly got to fit in this space. the strut brase may have to be lost, but i would rather keep it.



if you look closely you can see the spare pully I'm going to run the charger from. I have messured it up and using a guide from PPC i recon i should get roughly 7psi if not a little less. Of couse the intercooler will loss some pressure but I'm not going for all out power, just abit ...more....

Thanks for the help so far guys.

You may be able to get away with fitting bigger injectors perhaps, that will give you more fuel, you could get a narrow band o2 gauge. the piggy back turns out to be a resistor or diode that tricks the ecu into adding more fuel, generally accepted to be not that great in most cases due to bore wash but may help in your case, who knows? Is it an wire air mass meter or what? there is a chance you may max it out with boost, it all depends how adaptive the ecu is I suppose.

If it were me I would definitely use an intercooler and more importantly, Megasquirt ar some other programmable ecu.

If you used Megasquirt you could get rid of the AMM and use a map sensor plugged into the inlet manifold, have the intake at the rear of the bay, fit a heat shield between the exhaust manifold (and wrap the mani) run the charge air right up to the front through a long ic.

It costs more and seem a lot of hassle but do you really want to risk blowing up your engine?
