"Deck height" on VW's is usually considered to be the distance from the top of the piston to the top of the cylinder, not to the head (although I guess they are actually the same thing, since the head is pulled up against the cylinder). Since the head is the combustion chamber, and you can't measure it anyway, the deck height is the distance that the piston sits down in the cylinder (or sticks out). Basically, it's whatever you set it to be by using shims between the cylinders and the the engine case. It's not just a number that is set in stone, but a number that you determine you want it to be based on what compression ratio you want the engine to have. Then you put the shim that gets you closest to that number under the cylinder to set it. I did a web page on how to check it at http://home.hiwaay.net/~langford/corvair/trial_assy.html , but you'll also need to know the combustion chamber volume to calculate compression ratio, and that was shown at http://home.hiwaay.net/~langford/corvair/valvejob.html . If you take a stock engine and bore it out to 1835, your compression ratio will almost certainly be higher than it should be for aircraft use, but I guess that's a matter of opinion. I feel strongly that everybody should cc their chambers and KNOW for a fact what their compression ratio is on all four cylinders. Otherwise you're just guessing what's going on in your engine...

All the following is true if you run stock cylinders and pistons. But may I say, if you run with LN Engineering Pistons, Cylinders and have them CNC your Casing you eliminate the Sims. They have also reengineered the tie rod studs and anchors. Then you can choose the compression ratio by boring the piston at a precise position to make the C/R what you want. All aluminum material from piston to heads, including cylinder.

Reversing the engine front to back doesn't mean keeping the bellhousing. The only purpose it serves in our application is a mounting point for the starter and any machine shop with any competence whatsoever can whip up a new mount front aluminum plate to bolt right up. Without the bellhousing you have just eliminated any cowl clearance problems. Orma Robbins or R.S. Hoover seem to have the most experience with the VW so perhaps they can correct me if wrong.

As for me, I tend to go with what engineering and history have shown to be truths. I've raced boats, cars and motorcycles over the years and everything is the same. Better breathing, ignition, balancing and blueprinting before taking more drastic measures. 10 to 1 says you get the performance you desire just doing the above without having to shell out mega bucks for unneeded equipment.

The spreadsheet shows .053 for your engine. My question was meant to find the "minimum distance" necessary for piston to head clearance in our air cooled engines and not for setting compression ratios. I seated a leaky valve today and my deck clearance was .051 . I enjoyed tour web site and photos. Ryan ------------------------ Ryan wrote: > What is the piston to head deck height for an 1835 ?

Then you run out to your local VW parts store and buy some deck height shims. Since the combustion chamber volume varys from head type to head type, their is no "set" deck height. I'm sure to be flamed if I have remembered this incorrectly. -- Ross On Fri, 23 Apr 2004 17:58:08 -0700, Ryan wrote: > What is the piston to head deck height for an 1835 ? > > Ryan > _______________________________________ > to UNsubscribe from KRnet, send a message to KRnet-leave@mylist.net > please see other KRnet info at http://www.krnet.org/info.html -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/ ------------------------------ Message: 14 Date: Fri, 23 Apr 2004 22:12:28 -0500 From: "Mark Langford" Subject: Re: KR> Re: Deck height for 1835 To: "KRnet" Message-ID: <00fa01c429a9$f9e91370$1202a8c0@basement> Content-Type: text/plain; charset="iso-8859-1" Ryan wrote: > My question was meant to find the "minimum distance" necessary for > piston to head clearance > in our air cooled engines and not for setting compression ratios. Sorry I didn't answer your question, but then I'm not sure that's the question you asked either! Without digging through some stuff to check, I think miniumum safe piston to head/valve clearance is generally considered to be .060", but that depends on how brave you are, and stuff like what kind of RPM you plan on running. I've taken VW diesels apart that ran great but had imprints of the valves in the piston tops...
