I just got my SLP "siamesed" runners today. They are only siamesed for like an inch. Has anyone tried knocking down that center wall all the way through to both ends? I am looking for pics, instructions, tips, etc. if anyone has. Any help would be greatly appreciated. Thanks.

 

This isn't my work, heck I don't even own a pair, but here is a pic of some modified slp's I found on this sight a while back:

 

I emailed em bout that and they said not to. just do some mide porting and polishing. I'm gonna go down about 1" on teh end that isn't siamesed.

Those runners look terrible. Looks like someone used some kind of shears to break the pieces out.

 

This is the only picture I have:

I sold the setup to someone on the board. Check Dan Burk's site at www.ws6transam.org I think he has pics there.

 

I thought about doing this myself.
Does anyone know what effect or how this
will change the way power and torque are made?
I imagine it will help the engine make power at
a higher RPM. For the Guys that have done this mod,
what difference did it make on your car?

 

wait until kevin91z puts on his modified slp runners, he is having someone fully siamese the runners from top to bottom. im curious to see what it does to top end.
