EOI - Supercharger installation kits - now have good boost

So you want a hairdryer on your FTO? Or do you already have a hairdryer in it? This is the section for it. All other big power projects & forced induction goes here too.

That would be interesting to find out.

I've now got the pump running as of last night, no fan on yet but that won't be long (I have small windows in which to work on the car).
Just drove to the shops at lunch time and it was keeping the temps down holding in the 50's.
When I got back in the car they were up again (59) due to heat soak I presume and as soon as I started the car I could see the intake temp slowly going down, better than the 70+ degrees I was seeing the other day.

I'm hoping that the fan will make a big difference when I fit that to the back of the mini rad (it's a pull through) and i'm also going to fit a header tank to add more coolant to the system.

Promising results thus far for those temps

Yeah it's looking good so far, I rigged the pump to a relay that uses a switched live as it's turn on, and also put a kill switch in line with the switched live just in case I need to switch it off. Seems to keep running for a few seconds after the ignition is turned off which is an imobiliser thing I think as all my electrics do that.
I've put the relay inside the fuse box and the kill switch (has a blue LED to show when it's on) just outside the fuse box, for me that's neat wiring.

The ECU/Engine control circuit continues to stay on for a few seconds after ignition is turned off.

You don't happen to know what governs this do you, is it something built into the ecu or some timer chip somewhere?
I guess I should have a look in the wiring and electrical manual and see what I can find if I really want to know, was just thinking of delaying it for a few more seconds, or would this be a bad idea?

It's in the ECU

Ok cheers.
How much time have you spent going over those manuals?

I bet, just had a look at the Vectec version - good work :)


Fan is now on and hooked up to the other output from the relay so also comes on with ignition. I will update tomorrow with hopefully some good news about those temps coming further down, but really I think I need a header tank to add more liquid. I also want to test with ice just to see the difference, I know it's not practical for everyday driving but special occasions may warrant it...

Fill system with liquid nitrogen? :lol:

Feel like some components might not be up for it haha

I've added a little home made header box just as a test, it's only 1ltr but if it's good I will look around for an ally one that will fit. I can add ice to it easily if I want but haven't tried this yet.
Or if (I should say when) I replace the airbox with a nice air filter that sort of location may be a better place for a larger one as i'm out of room really, I've put this one near the engine mount drivers side.

After driving the car, leaving it, getting back in the temps are up in the 60's. Start her up and they start coming down straight away but they are staying within a range (the 50's), not going above when i'm driving and not going below and not creeping up when I pull up until I switch off.
And this is up in Broome WA (33 degrees when I did that test). Even leaving the car overnight and starting up in the morning the intake temps are already 30 degrees.

Conclusions so far
I had hoped for cooler intake temps post charge cooler, but then again this is the worst location for a temp sensor due to heat soak.
It's my opinion that the charge cooler is cooling the intake to temps colder than what an N/A car up here would be.
Boosting it doesn't make it go up that much, maybe a few tenths of a degree. and I think that's due to the nature of a charge cooler, they are great for consistency, but i'm still only on low boost due to a leak that I need to chase down.
I haven't driven the car hard for a long period yet either so this may yield different results to what i'm seeing right now.

Positives of the charge cooler
Zero lag, boost straight away and good throttle response (boost starting as soon as you go past maybe 25% throttle)
No intercooler piping to pressurise before even making boost it's straight from the supercharger, through the charge cooler and into the engine in a fairly straight and short path, this is also better for reducing pressure drop.
No stalling on lift off - on the old front mount setup that I had a few years ago after coming off the throttle you had to catch it by blipping as it was dropping to stop it stalling. The other people with supercharged FTO's running front mounts have also reported this and said it's a real pain. I have none of these issues and it drives great.
It is definitely cooling the intake temps, it may not be cooling quite is much as a front mount but I would say it may be more consistent. It's about 20 degrees above ambient.
The only pipe runs are for coolant and it's a separate system to the engine so no risk to the engine if a hose goes. The cooling side of things could be upgraded / improved on what I've done by having a larger radiator and larger fan and a larger header tank.
There is potential to add ice to the system for short runs like at the drag strip, this may cool the intake to below ambient - i'm going to test it.

Risk
I should add that there is a risk to the engine if the charge cooler core leaks coolant into the intake side and causes hydrolocking of the engine. I'm not too worried about whether or not this will happen - as it shouldn't, it's a quality core by Bell Intercoolers and it's not as if it's moving around on radiator mounts etc or under great stress.

Thanks mate, I will tidy the hose runs up when I get a nice header/ice tank in.

I added ice today, ambient was 45C, the ice lasted about a minute and brought the intake temps down about 2 degrees but not for long. I'm gonna need a bigger header for that to work even as a short term thing. (or move to a cooler place)

Run a big header down in front of the drivers wheel, heaps of space there

Not anymore, I've got the rad, fan and pump there.

I think I may run a second mini radiator for the charge cooler, can't hurt anything and it's an inexpensive option, about the same cost as an expensive case of beer.
Will mount this one behind the front grill when I get onto doing it.

For anyone thinking about using the kit in future, could they just utilise one larger rad for the charge cooler?
