b-nasty Posted February 28, 2009 Report Posted February 28, 2009 Just got my set of 68mm 4 mill cubs. Was wondering if anybody thought it was worth it to get them ported. Quote
kawiking Posted March 1, 2009 Report Posted March 1, 2009 ive heard about 7 hp from drag portin a cub . i had jeff at F.A.S.T. port my 4 mil cub Quote
RadarRacing Posted March 1, 2009 Report Posted March 1, 2009 I know Nate Mccoy at Mccoy's perf and Dan Hull at A/S can get a few more hp out of them. I always heard 3 to 8 hp. For $300 if you are really into draggin it might be worth it but they are pretty stout left alone too. Quote
moneybags Posted March 1, 2009 Report Posted March 1, 2009 If the person doing the porting knows what they are doing you can get some good power... Quote
00tbanshee Posted March 7, 2009 Report Posted March 7, 2009 i ran a set not ported then had kevin herr port them and its like night and day.i'd say port them! Quote
locogato11283 Posted March 7, 2009 Report Posted March 7, 2009 youve come this far, why stop now? have them ported. you arent gonna get 3-8 hp for $300 anywhere else. Quote
dragfan09 Posted March 7, 2009 Report Posted March 7, 2009 Calvin has gotten the cub cylinders real close. Some of the top builders don't do portwork on the cub cylinders anymore. That's why you can buy them ready to bolt on. I know there is a company that is changing $500 to do porting on cub cylinders. Ask around for pricing on portwork. $300 plus is for DM and bigger cylinders. Quote

Not only is there something to be gained from "just" port work, but it will be set up to work in unison with your pipes, combustion, and intake. No builder is going to want put their name on a cylinder without porting it, and I have never heard of a "top" builder saying a cub couldn't use a little work. Quote
flotek Posted March 16, 2009 Report Posted March 16, 2009 no matter how ideal the layout/design is as long as theres casting flaws, no fills ,uneven heights ,and misalignments due to the manufacturing process there will always be something to gain by correct porting and the cheetah cubs are no exception . :cool: Quote
dajogejr Posted March 16, 2009 Report Posted March 16, 2009 Obviously, compared to a stock cylinder with OEM porting vs a very good port job, you will NEVER see that kind of increase. But you can get more ponies out of them...without a doubt. Koolguy made a very good point. It's not just grinding on a cylinder, it's the WHOLE package for the motor, and then the setup to get that power to the ground efficiently. Quote
b-nasty Posted March 17, 2009 Author Report Posted March 17, 2009 Went ahead and sent them out along with my cases to get them done. Hopefully the money is worth it. Quote
