Charge cooling and some info on my Mazda
Hi,
First of all I am new to this site and have spent the past few evenings stuck to my computer reading the mass of interesting information !!!
Am I right in thinking the 2005 cosworth miata used an "air/water" intercooler ?
I saw this link in another discussion - Brightning Corp and wondered if that was the OE chargecooler in the pic.
I am currently in the final stages of designing my "air/water" intercooler system for my 1994 1.8 (which i have swapped a 1999 motor into). After getting the car something like how I want it (brakes suspension etc) Its time for some forced induction
Its now halfway thru its second major teardown and this time she's getting a paint job too.
Here is my cooler
I also have 2 x 12v water pumps and plan on using the a/c radiator as a heat exchanger. (with some extra trickery)
The car
New rotors fitted with Mintex "Extreme" pads
Before motor swap
The first teardown and rebuild (Dec 2007)
Old motor being removed
Motor out
60k mile 1999 replacement motor
Super clutch !
Manifold wrapped !
Gearbox cleaned
Almost ready to put this lump back in the car
After motor swap
All done ! (BBS split rims removed for refurb)
And this is what happens when you bottom out at 70mph
Replacing the Torsen...
And this is what happens if your air filter is not secured properly
The 2nd teardown begins !
Note the new washer fluid bottle !

Welcome aboard Will.
You should've started this thread in the "supercharger" section. You'd get more help there.
FWIW, I don't know of any member using W/A intercooler.

Thanks for the welcome,
I am very surprised to hear that nobody is using air/water setups
well, you can all see how I get on with it then I suppose.
Here is what inspired me - I saw this and thought about how short the pipework from the turbo to the inlet is - I like that idea !...
I will be custom building my turbo kit over the next year (i take my time).

In the meantime; if I were in your shoes, I'd seriously consider getting WI.
If you need additional info on superchargers, I suggest you get in touch with "formerdatsunman" (Bill knows his **** when it comes to superchargers).
BTW, nice ride.

I'm not going to be using a supercharger !!!
And yes water injection is also on the cards already
I'm planning on a GT28rs !
I think I know why you are confused, when I say "charge" I mean compressed air from turbo. I just thought I would clear that up hehe
I also plan on running the interior heaters from the chargecooler fluid to increase the water capacity. Its only a weekend toy which doesnt get used in winter and I usually have the roof down anyhow so dont mind leaving the heaters blasting the screen when temps get up.
Pretty much the only thing I havent decided on yet is an engine management system.

Plan
OK, here is a quick'ish sum up of my turbo plan.
My goal is to have a weekend car eventually capable of producing 300whp (maximum) but to run it at around 200-225whp untill I build my motor.
Response is something which matters to me, hence the;
short boost pipes
custom itb inlet
equal length split pulse exh manifold
3" seperated downpipe
extreme thermal management
freeflow cold air inlet
turbo choice (GT28RS)
(could go smaller with the turbo for response but would rather make it up elsewhere and still make good hp top end with a mid range sized turbo)
I have looked at all of these aspects for their help with spool/response. Obviously this will not fully give the desired effect on a standard motor with an MSD timing box but before i can build one and get good engine management, I want to perfect the turbo setup as much as possible.
Its quick and basic summary in the grand scheme of things, and my first turbo car/turbo system design and I would appreciate any feedback or pointers. Dont worry - you wont hurt my feelings and I appreaciate I may be wrong on much of this theory so fire away .
The main problem I seem to have is finding a turbo which meets my demands and the intake manifold design (particularly plenum volume and runner length).
The "Disco potato" (GT28RS) has ideal flow capabilities and good spool with its duel ball bearings as far as i can tell but doesnt seem to have "ext wastegate" or "twin entry" as an option. I maybe wrong ? Hopefully !!!
The external wastegate turbo's seem to have a much better shaped area (where the downpipe connects to the turbo) in terms of flow causing no turbulance if that makes sense !?!?! probably not !
Anyway its 00:58am here and I gotta stop thinking about boosted miata's and go to sleep (unfortunately!) or I wont have a job to buy all these nice shiny things
many thanks for reading and I look forward to hearing input from people with miata turbo experience/interest.

theres also some more vids of my car here if you'r interested - YouTube - williamjamesfrost's Channel

when my A/W WP failled I saw IAT's of over 100DegC, with the A/W setup working properly it's half that.

thanks for the info
I am now wondereing about the speed of which the water is pushed around the system ? I'm thinking too slow might lead to a build up of heat in the cooler and too fast might not give optimum heat exchanging ?
By the way Ferdi - thanks for the pic it looks really good Can you get aftermarket inlet manifolds for the protege ?
