Alright guys here is an update for you all with some pics.

First I tested pressure within the intercooler system. I plumbed in a gauge pre IC but post both HEX to see what kidn of pressure was feeding into the IC. I just wanted to get a sense of flow. I saw 6PSI. I would guess its significantly higher right off the pump as the flow in the system I would have guessed is below 5 GPM by a decent margin.

Lingenfelter pump flow data


After seeing that and knowing my IAT's are higher than they should be I decided it was time to take the plunge and pull the blower off. I had a knock sensor kick it just last week anyway so it kind of made sense hah

Here's where I stand:


Engine with blower removed



Blower on the bench



Blower taken apart


I didnt see anything that made me think air was in fact getting around my intercooler internally. Good news I guess? Although I would have been happy to see a problem as well. hah!

Anyway here are some close ups.

I had to use a lot of RTV on the spacer because the grooves for the worm and o ring gaskets were cut too deep... not ideal, but it is what it is. RaY said he would replace the spacer for me, but he is a few weeks out. So I'll be down for the next few weeks most likely.



Lower manifold and Phenolic spacer




Here is the view of the Intercooler from the bottom.



As you can see the spacer made a nice seal around the entire intercooler with exception of the bottom left of the picture... but I doubt that area was causing a problem for me.



Does anyone have any idea how to remove this wiring? I dont want to rip anything I shouldn't but I also want to completely seperate the IC from the upper manifold and blower.



After talking with Ray he said that the jackshaft blower being offset makes it use one area of the intercooler much more rather than disbursing flow evenly. Not good. I think the spacer lends itself to being even worse since it does not have the floor of the tub to help even things out.

I don't have anywhere near the skills to make a plate that would shift the blower over a little. It would be a hell of a project too seeing as the jackshaft itself would need to be raised as well. Either that or the bracket in the back needs to be updated for a different blower location. Either way its no small feat.

 

The connector should pinout from the back side of the connector. It should be a silicone rubber plug then pull it down over the wires then pin out. How thick is the phenolic spacer you are running?

RT

 

It's a half inch spacer.

I pulled the IC off the upper manifold last night. I'm playing around with a few ideas...

 

Alright so I have a few things I am going to try this winter, but for now I made sure everythign was back together and sealed correctly. I hope I have better results, but I dont feel super confident that I actually will.

Here's a picture of the blower back together.

 

Cruising around in some high 50's air last night this thing was a beast.! I didn't change the IAT much after taking it apart and cleaning everything, but they were never that out of hand anyway.

 

Looks like theres been a lot of oil inside there. Do you still run a pcv thru it?

 

I do... reason for the oil is when I first put the catch can on I actually installed it backwards. I thought the internals worked in the opposite way. I filled the catch can and sucked some oil through it... Lesson learned haha.

 

I'll be glad when we get some 50 degree air! Glad to see it is back together and working well.

 

I still need some details how u ran ur Catch can...i forgot, and i want to make sure i got my old lady rigged up right...it doesnt fill up like urs did tho...

 

The aftermarket parts are designed with looser clearances and will pressurize the block quicker, therefore sending more oil into a catch can. I also have the Holley valve covers that are notorious for having issues like that.

My catch can is designed to go from the valve cover to the TOP of the catch can where it has a filtration system that hangs down about 2" that is designed to turn vapor into oil liquid. The outlet port on the side of the can is above the bottom of the filtration system and that goes to the vacuum port on my blower.
