have to say this is great idea and a long time coming, i dont know what took so long, couple of questions for willren, the way that core is sitting in the LIM, doesnt that hinder air flow patter to all 6 cylinders? would a 1/4 or 1/2 spacer be more effective? im not poking at your design just curious about what might be more/less effective.

Somebody didn't read the topic. No spacer was deliberate for several reasons. You can't just simply raise it like you can the S2.

No, airflow isn't hindered at all. There'* ample room under the core for air distribution, and the fins being across the short axis are right in line with the ports.

The way it sits in there provides almost 2" of clearance to the bottom of the LIM. The bottom of the core is significantly higher than the top of the ports when viewed from the cylinder head.

I've been working on this off and on for a couple years actually. But only in CAD. I started with hardware about 6 months ago. The intercooler itself works great. The only reason I'm at it again is because I swapped lifters, and wanted to do a couple other things while I was there, then ended up causing more work.

A few things went back on last night. EGR, vac lines, a few smaller things. Weather was windy, wet, and cold. I knocked off early. Should be doing a startup tonight.

What'* this?

Yup. I drove it to work this morning. Ran very good this morning, like a bat out of heck, but my fuel gauge told me I better take it easy if I want to get home after work. Finished it up last night just as the rain started in earnest. Big cold front:

Still have to complete the re-routing of the IC inlet plumbing. Couldn't find my 45 elbow I bought for it last night, so I didn't finish up completely. Found it later in the kitchen where I'd been leak-testing the core/LIM.


Waiting for payday to order my new coils. Running fine on the 'oreo' mix I have right now.

The funny part is that I set off my neighbor'* alarm on his Expedition last night, and made the warning chirp go off this morning. WITHOUT the cutout open. There'* a sub-sonic note to the exhaust that I can't hear, which explains why Bo hates this car. The expedition was parked 3 cars away on the street, the Zilla was in my driveway. I also realized this morning that I forgot to reconnect both ECT'*, which are kinda a pain to get to, but I have all weekend to finish buttoning things up.

I'll get the plumbing finished tonight and start burping/bleeding the air out of the intercooler loop so I can get back to testing again.

With the car alarm it'* the high energy pulses that set it off.

With Bo, it must be the squealing of the SC lobes......or the rubbing of your tight jeans on the leather seats......he doesn't like the high frequency noise.

Good to see it'* on the road again.

My exhaust makes people several cars away think they have a vibration or other car trouble. It'* pretty funny, but my neighbor seriously needs to turn the sensitivity of his alarm down.

Summer time, my neighbors might not appreciate me driving this car as a daily commuter early in the morning. It'* not LOUD by any means, but things tend to vibrate at great distances from the subsonic stuff. The change happened mostly last winter with all the porting on the heads and installation of the rockers. It was amplified further by the new tips.

Ok, it'* running better than expected apparently. Without the intercooler even working again.

Greyhare and I just took the Zilla to lunch, and for the first time EVER, I got one of the hood vent covers to fly off. Granted, the extreme temperature changes today caused the front edge to lift up a little, but we gave it a little speed to do the deed.

Luckily, it didn't get rundover before I was able to whip two illegal U-turns to go back and get it.
