New Cylinders

[midlifecrisis]

I got my cylinders in the mail today, what do you guys think?

 

I was told they were .010 over, but on the top of both pistons it says 1.00mm, doesnt that make them .040 over? Or am I reading too much into it? I was also told that they were coming with a trail or mx port, is that what this looks like? There appears to be filler along the bottoms of the intakes then was smoothed out, does this mean that they have gone thru into the water jacket area? Or is this normal? Its more smooth than a regular casting and has been smoothed out alot.

 

Any input would be appreciated.

 

Also there is a recognizeable M S on the side of the cylinders, anyone we know?

I'm not an expert but wouldn't it be nice to see an intake picture

Here the respnse I got when I posted a shot of the intake

 

"Cant tell shit from looking at the intakes. Lets see a few pics of the transfers and exhaust."

 

Im the one looking for advice, Im the confused one?

 

Hers the intake shot, Im wondring about the filler in the corners?

Took a quick glance at you photobucket page. No idea who MS is and didn't notice the filler you were asking about. I suspect they used an epoxy to smooth the floor transition to the cylinder sleeve on the intake? I would be leary of doing this for fear the epoxy might come loose. The work looks to be fairly clean. However, the exhaust port looks quite wide for the application you were told they were for based on what I could see in the pics. But depending on intended pipes and target RPM peak you need to factor port area as a consideration. Make yourself a wire jig that fits snug accross the widest portion of the exhaust and measure it to get port width. Then get measurements of the cylinder from base to deck to see if they have been decked at all(not including the sleeve protrusion at the bottom). Then measure from the deck down to the roof of the exhaust and the roof of the transfers. Get back to me with these measurements and I can give you a better idea of what to expect. It's very hard to tell much besides port shapes and how clean the work is from pictures. Measurements would be needed. As for the piston size 1.0mm would be .040 over (65mm bore).

Dude,

 

If it wouldnt be too much to ask you to explain that in lamens terms. Im pretty new to this! Just explain a little about what each of those terms are and I can measure accordingly. I get some of it, and will measure right now.

 

My present mods that I know of are Pro circuit platinum exhaust, and a K&N filter

 

My mods to be installed shortly are, these new cylinders and a Vitos head with 22cc domes. I am at 300 ' ASL.

I have to apologize to the guy who sent these to me as I have misread his listing to me, it stated that these were 1 over and not 10 over like I thought.

Here is what I have tell me if something seems stupidly wrong.

exhaust ports o/d 44mm i/d 38mm

base to deck height 113mm

deck to roof of exhaust 31mm

deck to t/o primaries 43mm

deck to t/o secondaries 43mm

deck to t/o boost port 42mm

deck to t/o intakes 76mm

Seems like your exh port hasn't been raised at all, but your transfers and boost have been raised.

Whats that going to transfer into? This was sold to me as a mx port job

[mopar1rules]

well, based off a .017" (.43mm) deck height, and the dimensions you gave, your exhaust port is 179.13* duration, transfers are 122.47* duration, and the boost is 127.87* duration. blow down is 25.63*. pretty low IMO. i would shoot for 30*.
