BansheeMxer#45 Posted June 28, 2006 Report Share Posted June 28, 2006 could some one that acually ports motors tell me why it cost so much. i dont see how it can cost so much. thanks, not trying to be rude Quote Link to comment Share on other sites More sharing options...
mike23 Posted June 28, 2006 Report Share Posted June 28, 2006 I'm not an engine builder but your paying for horsepower. A good port job will double or maybe even triple your horsepower. That kind of upgrade doesn't come cheap Quote Link to comment Share on other sites More sharing options...
2003LimitedBanshee Posted June 28, 2006 Report Share Posted June 28, 2006 Knowledge, pure and simple. Not everyone knows what specifications a port job should conform to. How much do you open up the ports? How does that affect flow and flow velocity. How does it change the port timing? Where can you make small alterations and gain 2 HP? I by no means understand even a good deal, compared to the true builders (by profession) on here, but you are paying for the fact that they no the answers to these questions, and most don't. Also, to have the correct tools for 100% proper porting it costs a fair amount. I have to believe though that with a firm mechanical knowledge a person could port close to a good builder, but it will likely take 10 times the time, to make sure that you do it right. I plan on doing my own, with some help from RaceLogic templates, and then some tinkering from there. But you have to have the knowlodge, or take the time to fully understand what most builders already know. Quote Link to comment Share on other sites More sharing options...
BansheeMxer#45 Posted June 28, 2006 Author Report Share Posted June 28, 2006 triple my horse power from a port??? i still dont see how it can cost 300 to 600 to port a motor Quote Link to comment Share on other sites More sharing options...
2003LimitedBanshee Posted June 28, 2006 Report Share Posted June 28, 2006 triple my horse power from a port??? i still dont see how it can cost 300 to 600 to port a motor See above! I don't know that I would claim triple your horsepower, but you could conceivably take a bike from upper 40's to mid 50's into the 70's. Like I said, it isn't that there is $300-600 in physical work. It's called intellectual property. They have knowledge that most don't, and unless you want to go at it blindly yourself, you're going to pay for it.

lowriderb Posted June 28, 2006 Report Share Posted June 28, 2006 like others have said your paying for their knowledge and skill with the type motor. banshee's start out with about 30hp (give or take a little) a decent mild port job (with associated parts) will get you into the 60's pretty good, a specific built motor can a will yeild in the 90's or 100hp range (with the right set up)..

BigRed350x Posted June 28, 2006 Report Share Posted June 28, 2006 Any more you can just buy cylinders that already have the porting from the factory. Like the Cub cylinder. It already has what most builders would charge an arm and a leg for in porting. Yes, there is still work to be done on them, but they are a damn good running setup from the get-go. I've never been on a dyno, but I know mine is pushing around pretty decent power. If you try and teach yourself porting you will start to understand what it is they charge for. Go get some books on static/dynamic flow characteristics, and some porting manuals from the 80's and you will start to see... There is a LOT more than just rooting around in there with a dremel. Why are engineers paid so much? Anyone can slap some shit together, its the knowledge to do it safely and effectively that makes them the big bucks.

RIPPEN Posted June 28, 2006 Report Share Posted June 28, 2006 Well Said BigRed One thing that no one has mentioned is just the time it takes a builder to do it. Some clean-up ports may not take to long but i bet a "600 dollar" one takes some time. Another thing that porting helps with is setting up the power WHEN and WHERE you need it. Any badass bike you see that RIPS either has some sort of porting or a badass designed topend(cubs,trex, ect) RIPPEN Quote Link to comment Share on other sites More sharing options...
Fireman-hott Posted June 28, 2006 Report Share Posted June 28, 2006 Yep, but the reasoning for knowledge is eh given for free. really. Take a race logic and use either a dremel or air grinder and you're looking at 5+ hours not including if they squeeze into the transfers which the 2 year old race logic doesn't but the brand new supposedly(salt yo) does. at 5 hours for $300 your paying a basic labor rate at an auto shop that knows jack shit about 2 strokes. Really though unless you have 10 hours give/take 3, a dremel that just pay someone to do it. If your looking for top of the line drag dont do it yourself PERIOD.

chase@miamiatv.com Posted June 28, 2006 Report Share Posted June 28, 2006 you pay for knowledge and the understanding of a two stroke motor.... Once you see a few of your buddies smoke by you with less upgrades and a better port job you will understand... KNOWLEDGE IS MONEY , AND MONEY IS TIME !

I know it doesn't at mine. Quote Link to comment Share on other sites More sharing options...
chase@miamiatv.com Posted June 28, 2006 Report Share Posted June 28, 2006 You could always spend 200 and get a cleanup port :yankyank: just so you can put into perspective Im having my builder design custom pipes for the port work he is doing and he has a garuntee that he will make me more HP then the grand rivers or the jobs on him and for the price im paying hahahhahahahahah practically free :yelrotflmao: Thanks to stickers Quote Link to comment Share on other sites More sharing options...

I'd try like hell to find a set and run them just to chance getting a free port job. LOL Quote Link to comment Share on other sites More sharing options...
chase@miamiatv.com Posted June 28, 2006 Report Share Posted June 28, 2006 we ran the motor with the grr's and the port job it had , and i dont even want to say the # it was at ( its depressing ) low LOW . So he is garuntee'ing me the numbers i want ... i wouldnt consider the port job free because i have traded alot of work for work........ 10 thousand biz cards , 2 banners , 1 stand alone sign , a hundred stickers . We will just have to wait and see wont we ,Going for tripple digit hp's , lectrons and all. Will post pics when she is done , they are by far the fastest people in FLA. I know'n these people for close to 7 years , they are not just some radom people. We sold the pipes to a shop around here who wants them for a 16mill trex.... Im not worried i been wanting a set of inframes that will perform . will keep ya posted red - chase EDIT : ALL there bikes that they drag on , run there custom pipes. THEY ARE FAST AS SHIT !!!!!!
