Fast90 Woes - Leanness

[Bruce Melton]

I was thinking about that today. Bruce's latest entry makes me think there is no hope. I have 5.3's milled 0.024"

I still have my LS2 TB and and am looking for real alternatives for intake.

I don't know if you are following this L92 head journey but that looks very promising if the Aussie intake is decent. The heads are incredible and cheap.

This has been a heck of a weekend. Laptop took a dump and will be 6-8 weeks before I get it back from warranty.

Pulled the manifold to inspect for leaks and bottoming out. No signs of hitting bottom, but appearantly Blue RTV is not worthy of making manifold gaskets (between shells). Started scraping the blue RTV out so I can make a new black RTV gasket.

Although I dont' see signs of bottoming out, the port gaskets appear to have a problem sealing near the valley cover. One of the side effects of a previous sealing atempt, I managed to increase the thickness of a port gasket a good bit (will put the mic on it later this week). I'm thinking I may as well make all the port gaskets a little thicker.

I hate this manifold.

I used the GM o-rings/gaskets but you might check to see if the FA$T ones are different?

I've used the black rtv and the blue rtv (on various non-intake related things) but I like the copper rtv the best, it seems to stick far better to everything (including your face and shirt and door knobs throughout your house).

I can picture my boy running up with a smoking trail behind him, "Daddy Daddy, guess what?!"

Bruce - I've been thru both OEM and Comp port gaskets - I prefer the OEM. I got a few ideas while I was sitting in the waiting room. When things start to normalize around here, I'll give them a shot.

I'm starting to believe a Fast90 that doesn't leak is the cure for baldness.

I am interested then.

on the same note, I believe the leaking FAST is the source of baldness. http://www.myspace.com/taquickness
