Resleeving a GS1150 Cylinder Block

[chuck hahn]

Yes ...and several people HAVE told you but still you are discounting their answers. You can put as big as you want in in reality..but that doesnt mean its right when you take into acct stability of the sleeves and the PROPER amount of material that is needed to wick the heat off them so you dont scorch the sleeves..


This is what we are trying to tell you..you need to research what minimal wall thickness is recommended for proper heat disipation..this will tell you how big an OD you can bore the block out to.

Just like doing valves in a way. You get the seating surface as close to center as you can and an optimal band of 2MM..This assures proper heat transfer so you dont burn up a valve. The same principals apply to wall thicknesses and heat drawn off by the block..its all relevant and there isnt any PAT ANSWER really.

Say someone put a sleeve in and this left 5MM between each cylinder. Yes it works..but is that engine properly transferring heat at an adequate rate? Probably not when caompared to the heat transfer that 10MM will supply. See what i mean?

I'm well aware of what you are saying.
I have never asked "how big can I go". I simply asked "what is the largest sleeve/liner that you have used before breaking through a GS1150 block".
I don't understand why you are being aggressive. I asked a simple question... nothing more ... nothing less.

I have never asked "how big can I go". I simply asked "what is the largest sleeve/liner that you have used before breaking through a GS1150 block".

Then please tell me, ... what's the difference between those two questions? They are asking the same thing, using different words.

(paraphrasing here)
"How big can I go?"

or

"What's the biggest before it breaks?"

OK I give up. I have used the wrong wording.
Semantics ... English is not my first language ...

Instead of asking:
"What is the largest sleeve/liner (OD) that can be installed in a GS1150 block before breaking through the cylinder walls such as what happened in this one?"

I should have asked:

What is the largest sleeve/liner (OD) that you have installed in a GS1150 block before breaking through the cylinder walls such as what happened in this one?

too bad about some of the idiotic responses. lots of big hat no saddle stuff on this site at times

I don't know the answer to your question, so I did not reply.

Your english is fine.

That is funny

[chuck hahn]

Just leave it alone and stay stock.

Thanks derwood!

That's your choice and I respect it.
However that does not mean that I will "leave it alone and stay stock". If that had been my intention, I would have never asked that question.
To each his own!

See Bills answer in post 2. Get that.

See Bills answer in post 2. Get that.

That's if someone wants to use the GS1150 without resleeving.
I will resleeve ...

[storm 64]

Two words... BIG BLOCK. Lol

[quexpress]

Two words... BIG BLOCK. Lol

Would have been too easy!

Max?

Okay, I have some info that may or may not help.
I have 3.290" sleeves in my 1150 block to work with the 1290 pistons.
I believe the absolute biggest is 3.350". The aluminum material between is very thin and don't know exactly how much but with just a very small amount of press will either stretch or just crack.
The bore Centers are 95mm so you could make a very strange twin if you wanted. There is a better solution. Bore out past the air gap and press then weld in aluminum sleeves. Bore those and then press in some larger sleeves if you want a big but not obvious engine. Another is the same trick but forego the iron sleeves and plate the bore instead.
But in the end, may it's best not to break through the alu. into the air gap. Sometimes the oil can seep out.
I think 85mm max for the 1150's. If it helps.

That's EXACTLY the kind of information that I was looking for!

Thank you very much!
