I finally got all my gauges hooked up yesterday. Everything works great. Tranny, boost, pyro. But I noticed that my boost gauge starts bouncing very fast when I get the boost up around 26-33 pounds. Is this normal? I have the J-hook installed and was thinking that the spring on it is what was causing this....anyone else have this happen?

 

You need to put a snubber on it. McMasterCarr is where I got mine.

 

??? What is a snubber?

 

Go here http://www.mcmaster.com and search for snubber. I believe the one you need is halfway down on the page.

 

page 567..."Orifice-Style Low-Pressure Snubbers"

 

http://www.dieselmanor.com/dm_products/fittings.asp I got mine from Diesel Manor. It's called a pressure gauge stabilizer on the link that I provided. Took care of my boost gauge flutter. Looks like they're cheaper from Diesel Manor also.

 

You can also use a needle valve. About $2 at Napa.

does this part come with Diesel Manor's complete ISSPRO guage kits which include pressure gauges like boost and FP?

just got this setup and want to make sure it's there...

 

Unlikely...it will be extra.

 

you were right ...just ordered 2 of those; one for boost gauge and one for FP gauge. They are for pressure mechanical gauges for things like erradic needle or buzzing noises etc that may occur, so I figure why wait for a potential problem when you can take care of it once and for all during installation
