Oh wow, that is a bit rich, but not too bad. What are you going to try and run at WOT A/F? What I/C pump are you using? Is that a Bosch? What info do you have on it?

Same Bosch pump used on the cobra'* and lightnings.

WOT AFR I'm targeting between 12.0 and 12.5. Safe on the rich side. Without direct access to the PCM on the OBD1/S1, it'* a fine balancing act, but I'll get it.

Got the pump from the W-body store.

My WOT AFR last year was 10.9 A little rich When I adjusted the MAF to almost 0 LTFT, it leaned out a bit at WOT to about 11.5.
12.5 is where I want to be with the Meth injection.

I thought that was the pump. I am using the same one but I got it for $30 from a guy who was going to upgrade it to his cobra and changed his mind . I can't find any info on it though. Do you know if this is a centrifugal pump or positive displacement? I assume it is a centrifugal pump. I'm using the SSIC and I've been told that centrifugal doesn't work well with it so I am wondering if I should go to a flowjet. It supposedly runs better with cores that have smaller internal diameters. But it flow less, is louder, and draws more amperage. Any thoughts?

It'* a centrifugal. Very obvious by it'* design. I can tell you from my tests, it flows an amazing amount of water. It worked well on my bench test, and I expect it to in the real world as well (hoping for at least half the thermal efficiency of the static test due to extended boost runs).

I don't know the flow specs on the pump. Shouldn't be too hard to find though. I've never tried to look it up, as this pump was chosen to fall into a pre-targeted budget.

The way my inner core works (helical inserts) I think I'll make the most of the potential of the pump. On typical intercooler cores, that feature isn't in there.

I found a small leak where the barb fitting mates to the copper going into the LIM on the front side. Simple fix (just need to remove the flex line, unscrew the fitting, re-seal, and put it back, then burp it again).

Flow is VASTLY improved now. I'm still getting some micro-bubbles, but they'll work themselves out in the reservior/check over the next couple days.

Greatly encouraged in the potential.

Test setup:

1. Still have microbubbles circulating in the system, with the occasional table-spoon sized bubble.

2. Fully heatsoaked with the high speed fans on, but the hood is open, and there'* a good 4" gap from my new IC radiator (then half of that flows through the trans cooler) before it gets to the radiator where the air is being pulled through. No forward motion. This amounts to very little flow.

Let it heatsoak until my post-IC LIM probe and gauge read 115 degrees F and settled there (49 degrees ambient IAT'*). This is heatsoak in the LIM from the engine heat and coolant running through the LIM.

Turned on the IC. Note that I'm in boost bypass in park/idle. The bypass blows between the two 180 degree 'loop' returns in the core, not through the core itself. IC dropped from 115 to 99 in 60 seconds, in spite of these conditions. What that means is that the bypass air from the SC is circulating around just the bottom of the IC core, not actually flowing THROUGH it.

This isn't much of a test, but it is interesting how effecive it is in spite of the odd flow at idle/boost bypass.

Encouraging results inspite of being in bypass and forward flow thru the rad
Now get them bubbles out

Hey willwren, Vibrant sells custom sized air-to-air intercoolers that are rated all the way up to 875HP. The one I am looking at for my Bonny will slip in behind the front fascia. Features premium Bar and Plate Construction to provide superior cooling efficiency and overall strength compared to traditional liquid cooled intercoolers. I sell them to a lot of these tuner guys putting massive turbos on little four bangers. Much better flow too. Just thought it migh be easier than messing with the cooling system. http://i111.photobucket.com/albums/n...12815_WEBS.jpg

You obviously aren't familiar with the Series 1.

First, air to water is more efficient. Secondly, you can't fit an air to air in between the SC and LIM on the Series 1 because you can't raise the supercharger. It supports the accessory bracket. That'* the whole reason it'* INSIDE the LIM on my prototype in the first place.

If I'm going to bother doing this, I'm going for the higher efficiency. Air to water. If you research efficiencies (including listed in this topic) air-water is almost always the better choice.

I'll be making an extended test run (in spite of bubbles) tonight in about an hour. Gotta take Katie to Albany and back.

This company " VIBRANT Performance" boasts that their intercooler out performs any air to water cooler. And you are definitely right you can't put the intercooler in I am taking about. I have been dealing with a lot of turbos lately and didn't even stop to think about it. The intercooler you are using sits underneath the supercharger and cooling as the air passes by right. The other supers I have seen besides these are the ones mounted on the front of the engine and passed through an intercooler in front of the radiator then pushed back up to the intake. What kind of supers are on the bonnies? (Roots, Lysholm screw, Sliding Vane, Pressure wave, ect)
