Yeah, but it will never boil anyways, so there's no point. Water has a higher heat capacity then just about any other fluid you'd want to use, so it's pretty much the best. If you have cold weather you'd have to run antifreeze, but i'd run as little as possible as it will hurt the coolers efficiency.

it's relatively tricky to set them up 1st time when you don't know how they should be setup
but once you realise the charger throttle needs to be cracked open whilst the stock TB is shut it's pretty simple ![](https://www.miataturbo.net/images/smilies/smile.gif)
Stock TB with a JDM SuperHI pully overlayed
I filed out the slot to slightly 'cam' the secondary pully as it's range of movement isn't as great as the stock one.
Throttle cable route, your setup would differ here as our throttle cables are really short due to being right hand drive, and we need really long throttle cables when fitting superchargers.

Very nice routing....
So the BTB is basically open slightly while the stock TB is completely closed? Then it would be open fully while the BTB is wide open too?
Hum.... interesting. Maybe it's time to upgrade to a BTB? <G>

Very cool. OK, so your RHD stock throttle cable goes to the stock TB, then you have your "extension" throttle cable go from there to the BTB? Looks almost like you have "one cable, with just a piece in the middle to expose the cable for the "cam" on the stock TB.

steelrat, I don't have a BTB... But the principal is identical
there's 2 distinct throttle cables, using 1 would be very cool but I woultnt want to engineer it!
Oh I also losened the charger TB return spring as the throttle gets a little bit heavier with 2 throttle bodies
Barbycar: the IAC goes in the stock location, it's tidiest and gives the best idle which is half the reason for dual throttles anyway!

Cool.... figured the IAC would be on the stock TB (better idle reactions then).
So which TB are you using? A second stock TB on the blower? Aftermarket? Is it still the same size as the stocker?
So I assume the stock TB, has the TPS on it, for the ECU.... (I know MS In your case), then you have just the throttle cable for the "Blower TB"... and the ecu doesn't care about the electronic position?
The second throttle cable, is that the one that you guys needed to get for a RHD/vs. LHD? Or did you pick up something aftermarket?
On a side note, I was wondering if the bigTB would fit on a 4-rib, I got the impression, that it might be a very tight fit without having the additional space from the 6-rib blower position.
Still, this is very, cool.....

I'm using a 2nd stock tb tho it's got a weird non leneir action.the TP sensor is in the stock location, there's nothing on the blower tb
as you say the ecu is unaware of the 2nd tb so doesn't care it's position
Funny you should mention the BTB actually, I want to DIY a BTB conversion, from what I've seen the 6 ribs don't move much further forward ... I am helped by not having a brake MC in the way mind....
