jbooker82 Posted April 4, 2014 Report Share Posted April 4, 2014 I am just on my phone and can't seem to see the triple port, nor does it look like the out side of the cylinder has been built up for the triple port. If I was spending the cash for a 7mm motor I would just go with a 10mm since you have to trench the cases ethire way. Quote Link to comment Share on other sites More sharing options...
BANSHEE HP Posted April 4, 2014 Report Share Posted April 4, 2014 I see the triples and its the domes accommodating the stroke not the cylinder Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted April 5, 2014 Report Share Posted April 5, 2014 Meh, surprised they snuck the triples in there with out welding. That's one hell of a tricky thing to do. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted April 5, 2014 Report Share Posted April 5, 2014 Def very tricky and it differs from cast to cast I have experimented on a few sets and only got one perfect with no welding Quote Link to comment Share on other sites More sharing options...
registered user Posted April 5, 2014 Report Share Posted April 5, 2014 if your goin to all the trouble you might as well do it right and make them fukers big as you can. i dont see them being very big just from the thickness of the casting Quote Link to comment Share on other sites More sharing options...
Whitbread Posted April 5, 2014 Report Share Posted April 5, 2014 After doing triples on mine, I don't see how you could do any passage larger than 3/16" to 1/4" TOPS without welding. There just isn't that much meat in there to leave any wall thickness without welding. After doing it, I'm just going to buy triple exhaust cylinders next time unless these run like the best thing since sliced bread. I really want to do a PV motor next time around though. Wonder if twister would do a pv small block.... Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 5, 2014 Report Share Posted April 5, 2014 Why you want a power valve? drag cylinder with more broad power range? 1 Quote Link to comment Share on other sites More sharing options...

Wonder if twister would do a pv small block....Mostly it's only his monster Big Block cylinder that has the PV's. I think his Sniper might get it as well. He may still have old style cyls around though. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 5, 2014 Report Share Posted April 5, 2014 Well how about a super serval. Nice broad power curve(especially the TQ) when ported right. Quote Link to comment Share on other sites More sharing options...
Whitbread Posted April 6, 2014 Report Share Posted April 6, 2014 Why you want a power valve? drag cylinder with more broad power range? Not everyone here is a drag racer, that's why. Mine is setup for woods/open fields/100+ mile trail trips. I want the widest, smoothest powerband possible with the best chance of reliability when I'm 100 miles from home, not the most HP possible or fastest 300' time. A 4mil smallest bore sized twister small block with pv's would be my exact choice if Louie would make it for me. No nicasil to deal with in case of shit happening, no random casting porosity like pv cheetah's have every now and then, and basically the same cost. Should be around 100hp easily with a super wide powerband. I could build it with the compression in alky territory and dial my timing way back to keep knock at bay (can even run knock sensors if I want), then dump in e85 and let microsquirt wake it the hell up in the extremely rare event I end up a drag strip. MS has built in support for a flex fuel sensor and will automatically change timing and fueling maps for those who aren't familiar with it.

RagunCajun Posted April 6, 2014 Report Share Posted April 6, 2014 Well no nikasil means no cp cylinders like a big serval Which is everything you need other wise. Quote Link to comment Share on other sites More sharing options...
special06shee Posted April 6, 2014 Report Share Posted April 6, 2014 What is all this serval drag race talk? You's confused? Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted April 6, 2014 Report Share Posted April 6, 2014 It looks like you are confused. I mentioned it since he isnt looking to drag race. He wanted relible broad power so I mentioned a serval. Quote Link to comment Share on other sites More sharing options...
