EGT's down 300 with just an intercooler. Looks like thats my next move then!!!
Did you notice any more power?
That thing looks CRAZY COOL Owen. 
yes, less boost and more power..
intercooler inlet piping gets burning hot, outlet side, and intake manifold are all cool to touch..

It's a little hard to say about more power... I can certainly stay in the throttle longer which makes the car faster, but it does not feel any more powerful than before.
Does not pull harder, just longer.
And the 300* drop is because I was so hugely out of the charters efficiency range that I was pumping some seriously hot air into my motor.

any thoughts on doing a Super-turbo?

that is my eventual goal, but time and money constraints have kept the turbo on the shelf(literally, it is sitting on a shelf)
the plan is to have the supercharger take up the low end(where the rather large turbo would have trouble spooling) and then open the bypass when the turbo has woken up, to retain some efficiency on the top end.
all of this will come, in time.

you should look at getting a clutch for the super charger (benz kompressor) so you dont have to spin it while the turbo is alive..

there is no clutched pulley small enough(I am going to a 1.9") for my charger.
it has a bypass valve in it that effectively removes the charger from the intake, so all it does is spin. according to Eaton, the charger only takes 1/3HP to spin in bypass mode at 6000 engine RPM.
the other issue with a clutched pulley is that it introduces huge load spikes to the drive belt when engaging, which might shear the woodruff key on the crank.

having (more) troubles with my glow plug system...
computer that controls them went tits up, and now I cant get the dropping resistor to work right...(stupid 6 volt glow plugs)
so I went looking into intake heaters.
not alot around except for the cummins ones, which are big money and even bigger draw on the battery(400 amps or something stupid like that)
so I did some research and found this on a cummins 4BTA swap forum:
its a Thermostart intake heater, used on ford tractors.
it has a small heating element, and a low-pressure fuel connection that does this when turned on:
its called a flame intake heater!
they only cost $20 or so, and have been used with great success for the cummins guys.
so I got to thinking, it would simplify my starting aid system, and there is already a place to put it in the intake elbow(where the dropping resistor goes)
what do you think?

just bought one, figured for $23 shipped I would give it a whirl!

Whoa.. that's awesome! Maybe that could be helpful in the 15:1 TDI I'm secretly dreaming of in the back of my mind!

If nothing else it looks cool and if it doesn't work for you then you could take it and roast things.

I think I am gonna wire the glow plugs to be "pimped" off a pushbutton as well as the thermostart.
I have a spare dropping resistor(that is external to the intake), so I can use that to re-wire my GP and can still loose all the fru-fru of the self sensing system the car had.
that way I can use the GP for warm weather starts, and the thermostart for winter(the GP would sometimes take longer than I would like to start the car in winter)
I will keep you all posted on progress!

Owen, My Olds has 6v glow plugs with a stupid little control module that also went tits up..
Since the original controller just pulsed the GP's with 12v at a constant rate I got to thinking, turn signal blinker!! Works real damned slick.. I have the blinker controlling the original GP relay..
Icing on the cake?? I used a VW fast glow controller to run the turn signal blinker... I made an adapter to fit the VW temp sender into the port for the old GP temp sender, so it even varies the time they are pulsed according to temp, which is how the original module worked...
Some day when the time comes to replace the gp's I'm just going to install the 12v ones as the 6v ones are kinda funky to come by.. But I still may keep the VW controller less the turn signal blinker..

this thing was supposed to cycle the plugs at 12V for 5 sec when cranking, and then hold them at 6V for up to 60 sec(with the aid of a dropping resistor)
but while I was playing with the relays and my multi-meter, I'm not sure how it does this as the dropping resistor and glow plugs seem to be in entirely separate circuits.
the glow plugs all test out dead(varying degrees of dead, but all outside the allowed resistance) and when the relay is triggered I get twelve volts at the buss bar(would explain having to replace them twice in one year)
supposedly there are twelve volt glow plugs available(which would make the revised wiring alot easier) but they are hard to find...
what do the 12V glow plugs for the GM diesel look like? (as many as the injection parts are the same, the plugs might be the same too)

They are similar to the 6.2/6.5 GP's, however they are different part numbers... I had a hell of a time finding 12v gp's for my Isuzu powered tractor.. Seems that in most applications they used 24v gp's in them... I finally took measurements (diameters, thread pitch, distances between steps) and was able to match a set up...

well, I just found them!
$70 ea, and $6 shipping for a set of four!
gotta love google and ebay!
going to buy a set right now.
