Water/methanol injection

(1/1)

Ohiobenz:
OK, this is a data gathering question....
Who is running water/methanol injection on a turbo diesel???
I'm not interested in theoretical responses....
If you haven't done it, aren't doing it, please don't clutter this thread with your responses....
I can Google as well as you can....

The objective is to reduce EGT. I'm running a 1.6TD, Giles performance built pump, O-ringed block, KKK14 turbo, intercooled, at 15-17psi sustained it starts hitting above 1300F.

I have a junction where a fogging nozzle could go just ahead of the turbo intake, or I could put a nozzle post intercooler just prior to the intake. Which is best and why?

Again, I'm not looking for your theoretical input - but actual "been there done that" experience!
Thanks!!!

Ohiobenz:
Surprised to see no responses....

I'm at a point that I need to pursue this.  Freeway driving above 65mph is tricky. Under uphill acceleration EGT's get above 1300F.

I'll gladly share my experiences as I work through this mod.

I've put almost a 1000 miles on the motor since the work I did on it.

ORCoaster:
I don't have any experience with Met injection systems but I am curious as to why you are running 1300 degrees of temperature at 65 MPH.  How much fuel are you putting into those cylinders?  What kind of economy can you be getting with that much diesel burning up or maybe not.  That is generally why my exhaust temps climb.

Black smoke is wasted fuel and your EGT is going to spike when it happens. 

Just curious. 

Ohiobenz:
It's in a Suzuki Samurai.  Transfer case is geared down, at 65mph it's running about 3500rpm.
Giles built the IP pump to handle 25psi but I put a Forge manual boost controller on to keep it down to15psi.
I'm getting 20mpg for the last couple tanks.
Cruising it's all fine, 10-12psi, 8-900F EGT's, 190F coolant.
Once I get heavy on the throttle the EGT's start to climb.

ORCoaster:
Since you have it geared to run at about the max torque at 3500 mph any additional needs when under a load will have to come with higher fuel needs and RPM's.  I don't think you have any hope of cooling it down.
