Inlet temp
Sierra - 15/8/13 at 08:44 PM

As I'm preparing my car to do a few track days I'm a bit worried about the inlet temps getting too high as I run a m45 supercharger with no form of cooling apart from standard rad.
How and where would I put the sensor as the supercharger is bolted directly to the inlet?
What/how can I install something to help cooling?
What is that clear tube I currently have coming out the top? (I should know this I know)

My guess is that the clear tube goes either to the fuel pressure regulator or to the MAP sensor, or both.

Regarding heat of the inlet air, you might consider moving the inlet cone from behind the radiator (hot air) to somewhere in front of the radiator (cold air).

I'm not sure how you can fit an intercooler.

If you cant fit an intercooler then google / youtube water-methanol injection.

Sierra - 15/8/13 at 08:56 PM

Yeah I'm in the process of finding a new way of doing the filter as there's not enough room in front of rad. Also need to change the rad as I've got brown water at the moment so probably go for a polo one

Yeah I've been doing some reading up on that, a friend of mine has a heavily modified cossie engine with an inter cooler and water/meth injection and said he doesn't rate it. He said it doesn't work half as well as an inter cooler or charge cooler would

What boost pressure are you running?

It will be very hot inlet temps without a intercooler, you can get cheap temp gauges on eBay

beaver34 - 15/8/13 at 09:08 PM

Also it's got a temp gauge in there at the moment by the looks

That what I thought when I first saw it but I've only got a oil pressure and water temp gauge.
The supercharger is currently set at 6psi

It probably goes to the ECU, so maybe there is a way of logging it.

I don't think I have ever seen an inlet temp gauge.

What ecu is it on omex?

Cheapest way get a digital thermometer off eBay and put the sensor in the inlet with the gauge on the dash there about a £5

I would be looking for a cooler though, mr2 intercooler will fit in the nose infront of a polo rad, cheap too

I had a custom one made for my turbo engine though

Sierra - 15/8/13 at 09:51 PM

Yes it's an omex.
The problem isint fitting the intercooler itself but the pipe work as the supercharger is bolted directly to inlet

mark chandler - 15/8/13 at 09:59 PM

Thats an inlet temp sensor for the ECU, the clear pipe should go to the MAP sensor and fuel regulator (its been left open) if not sourced elsewhere.

I,m guessing that the big black box is acting like a big plenum to open inlet tracts with a throttle body infront of the supercharger.

It will generate a lot of heat, you should be able to get a matrix in there for an air/water intercooler and have a second rad up front as its quite a long way from the head, quite a lot of rework but worth it for the power gains and safty margin.

Do you know of any companies that'll do this for me as I really don't know what I'm doing when it comes to this.
Also I bought this a while ago and was just thinking if it will display the inlet temp by buying a sender. It does say thermometer

You could add another air temperature sensor and wire it into the Koso.
If you do then you need a sensor that is designed for air temps. These are low thermal capacity as the air temp changes can be quite dynamic.

I didn't notice the fuel pressure regulator in the background (oops).

Sierra - 15/8/13 at 11:08 PM

Why oops? Should there be a vacuum hose on the top as there never has

To keep temps down a laminova style cooler would work well inline with the supecharger output/ inlet manifold.

Not cheap though, but i`m entertaining using one.
