Title: Minimum deck? Post by: TexasTom on October 05, 2009, 23:18:01 pm What is the absolute minumum piston to head clearance you've successfully run?
I usually look for .040" as minimum, but considering the possibility of less for a limited time. 82 X 94, carrillo rods, compression in the 10.5-11:1 range. Title: Re: Minimum deck? Post by: DKK Ted on October 06, 2009, 01:43:04 am I was told by a good source that no less than .040. I've ran a ZERO deck with a .040 copper head gasket with no problem on my 2303 a few years back.
Title: Re: Minimum deck? Post by: Bruce on October 06, 2009, 04:36:18 am There's no one-size-fits-all for the minimum deck height you can run. The min depends on many factors. Stroke, rod journal, main journal, connecting rods, cylinders are all just a few of what determines how tight you can go.
A 69 stroke VW journal can take much tighter DH than an 84 stroke Chevy journal crank. Using Pauter aluminium rods? You'll never get away with 1mm of DH. Title: Re: Minimum deck? Post by: TexasTom on October 06, 2009, 04:38:55 am Bruce,
I agree completely ... The stroke is 82 (Okrasa) with Carrillo rods, 5.352". ;) Title: Re: Minimum deck? Post by: Bruce on October 06, 2009, 04:43:44 am What are your journals? Chevy? VW?
Mains: Type 1 or 4? Title: Re: Minimum deck? Post by: TexasTom on October 06, 2009, 15:00:47 pm It has type 1 mains, Bruce.
Good components, but old school as they say; Okrasa, Berg, Fumio and the like. Think I'll stick the .040" rule ... ;) Title: Re: Minimum deck? Post by: 58vw on October 06, 2009, 22:55:10 pm new school tom new school....u know what im talking about..... ;D
