Phenolic Blower Spacer

[PDXGTP]

Andrew, you do nice clean work

I would be interested in that phenolic spacer. Why did you have to paint it?

Bill, I know it was'nt quite our norm but last week we had seven straight days of 35C spiking one day to 102F and my temps were up only 10F more than normal.....but ya I had to use the water injection full time because of my heavy foot.

I thought the paint looked better than the raw brownish color of the phenolic. Only the top and sides are painted. Being a flat paint, it would come off with some carb cleaner and light pressure, without harming the phenolic. Or consider it a primer for some gloss black (worked on my block, heads and resin VC's)

If the OP doesn't claim it by, say, Sunday night, you're welcome to it.

Andrew, I think the thickness of that spacer alone might be ok with the injectors, but after you install a gasket on each side? Might not have that luxury. It might be a case of sealant alone on each side of the spacer.

I also have my doubts as to the effectiveness of a 1/8" spacer. That's hardly more than 2 gasket thicknesses.

Did you do any bench testing with it sandwiched between a hot LIM and a supercharger? I got a tingle in my that sez you probably did.

I did not do any testing on this thing as a heat-reducer. Truth is, I did not even make it for that purpose; rather I made it as an adapter--a temporary means to mount a gutted M90 casing to my IC-ported LIM while I worked on the IC core and my modded fuel rail. (But I got the core and rail done faster than expected so never needed the adapter).

So, would this really work as a heat-transfer reducer? I don't know. Heck, would even a 1" thick version work? I don't know that either.

I'd say the gaskets are not more than 1/32" thick each. I've still got a M90 casing, and L67 head, LIM, FR and injectors on the shelf, so I can test the fitment on the bench this weekend. To me, the 2 main fitment questions have to do with the stock rail and injectors:
1) Do the injectors still nest far enough into the cylinder head injector bosses?
2) Does the rail foot closest to the alternator still clear the S/C bolt head?

It may be that the part of the rail where it bolts down to the top of the charger--just before the feed/return ends--may have to be "massaged" (i.e., bent ) just a little to give the injectors enough slack--or that some M6 washers under the fuel rail feet will do the trick; we'll see.
