Strm Trpr Posted September 28, 2013 Report Share Posted September 28, 2013 Just for future reference, Crankworks DOES make a forged 10mm crank,, not just billets. Ah, thanks for the info! Quote Link to comment Share on other sites More sharing options...
fappy'97 Posted September 28, 2013 Report Share Posted September 28, 2013 Yep, that's why I'm building a 4mil pump gas dune port stk cyl as my Duner and save myself the $800 price tag for aftermarket cylinders. At 64.5-65mm bore it's a 379-385cc 4mil stk cyl. Here's what you get from FAST for a 421 Serval. $1723 + $350 for porting. So ~$2100. http://www.farmandsandtoys.com/partdetail.asp?partid=403 For ~$800 less you can have a 4mil stk cyl making ~80rwhp. But if $$$ is no object, get the 4mil Serval. Do the math again. 80hp on stock cylinders vs 80hp on a serval...... You're not saving $800 Quote Link to comment Share on other sites More sharing options...

You're not saving $800 Oh ya, my bad, you need to run race gas to squeeze out 80rwhp out of a 4mil stk cyl dune port. Quote Link to comment Share on other sites More sharing options...
Pacific Barbarian Posted September 29, 2013 Author Report Share Posted September 29, 2013 Defintitely only pump gas for me. We get very consistent 95 octane. Sent from my GT-P7500 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
