snowmanzz13 Posted August 19, 2007 Report Share Posted August 19, 2007 well, i'm looking for some out of frame pipes (because i really like the look and sound), but my motor is basically stock. t5 pipes for now and a k&n filter. i'm lookin to pick up a cool head an run 18cc domes when i run at the track but am i really going to get the power out of oof pipes like cpi's or shearer's with that kind of setup or is it overkill? thanks guys josh Quote Link to comment Share on other sites More sharing options...
375hp banshees Posted August 19, 2007 Report Share Posted August 19, 2007 waist & they wont sound the same either, not enought air flow Quote Link to comment Share on other sites More sharing options...
375hp banshees Posted August 19, 2007 Report Share Posted August 19, 2007 18 's down here are on the verge of mixing gas too, so check your compression after !! Quote Link to comment Share on other sites More sharing options...

zach45 Posted August 19, 2007 Report Share Posted August 19, 2007 (edited) your gunna lose power you put them on a stock motor.. gunna be a waste... Edited August 19, 2007 by zach45 Quote Link to comment Share on other sites More sharing options...
snowmanzz13 Posted August 19, 2007 Author Report Share Posted August 19, 2007 so could i run cpi inframes? i see alot of people running them and i want to be some what a competitor at the local strip, i got murdered buy a 450r an i want to show him whats up lol, but what all would i need to do to be able to run drag pipes? i'm really eyeing a cool head with 18cc domes an maybe some v force 3's in my near future Quote Link to comment Share on other sites More sharing options...
chevy7398 Posted August 19, 2007 Report Share Posted August 19, 2007 porting, reeds, carbs, filters Quote Link to comment Share on other sites More sharing options...
alcoholbanshee Posted August 19, 2007 Report Share Posted August 19, 2007 Honestly for the 4 bills it will cost for a coolhead and v force.... you could spend a little more than that and get a port job, rechamber the head and some good reeds. You will see a much bigger gain from this than you will ever see from a coolhead and v forces. Then buy some out of frames and some bigger carbs and you will beat most 4 strokes!!!

snowmanzz13 Posted August 19, 2007 Author Report Share Posted August 19, 2007 well i just picked up a cool head off of ebay for $140, i'm going to run 18cc domes, i have a set of 34mm pj's out in the garage i might think of throwing on there an maybe a all around port job might be in my future, but i still want to be able to go out and ride in the mud on some weekends and hit the strip the others, i want a very diverse bike because the track near me only allows quads 1 time a month, again any help is appreciated as i basically see whats suggested is a port job an reeds, if i can get a deal on some reeds then cool cool i might dump a little money into a port job, again thanks for your replies and all help is appreciated Quote Link to comment Share on other sites More sharing options...
375hp banshees Posted August 19, 2007 Report Share Posted August 19, 2007 all an eng. is, is an air pump... most mods. let the motor breath (in or out)better.. the more flow through the pipes, the sound will change & most of what you here ( & like the sound of) is larger volume cylinders along w/ higher compression to make that appealing sound. a port job is your best gain period ,even if you don't do anything else (now except pipes which you have) then every thing you bolt on will complement the port as you buy them... you just need to decide what you end goal is before you start, because it all needs to END UP complementing each other (but by then i'm sure you'll want something else & be starting all over again anyway LOL) do your self a favor & check your compression as soon as your done changing to 18cc's!!

snowmanzz13 Posted August 19, 2007 Author Report Share Posted August 19, 2007 yeah i plan on doing a compression test to see what octane i neeed to be running at, i guess my next tear down i'll be getting a port job as thats what is suggested by most lol i def understand that whole changing ideas lol i'm already changing, i first wanted a realiable mudder, now i'm trying for that drag racer/mudder combo it's just fun to change lol thanks so i guess i'll stay away from drag pipes for right now and keep running these t5's Quote Link to comment Share on other sites More sharing options...
jayzx10r Posted August 23, 2007 Report Share Posted August 23, 2007 (edited) well, i'm looking for some out of frame pipes (because i really like the look and sound), but my motor is basically stock. t5 pipes for now and a k&n filter. i'm lookin to pick up a cool head an run 18cc domes when i run at the track but am i really going to get the power out of oof pipes like cpi's or shearer's with that kind of setup or is it overkill? thanks guys josh Here is something I wrote for another member about intake/porting/exhaust: I kind of look at it like this. Understand that I don't know what your level of mechanics is so I'll try it as if you don't have much experience but this is just a generalization of concept. Understand, this is an oversimplification. 1. A motor is basically an air pump. 2. By removing areas of constriction or inefficient shape, you can increase fuel/air (A/F) flow. 3. There are basically 3 areas to look at...carburetors (intake), engine porting, and exhaust. 4. If you restrict flow to 1 of these 3 areas, you end up choking the whole motor, reducing the power output. Generally, more flow = more power. Carburetor: A carburetor is the ultimate expression to result of restriction. As the slide closes, it significantly reduces the power output of the motor by restricting airflow. That same effect can result from any other component of the engine that hinders or restricts the smooth movement of the air/fuel charge. I point this out so you can visualize the result of the effect of restriction. Porting: An oversimplified explanation is that the engine transferrers the A/F to the combustion chamber in the cylinder via Transfer Ports. In stock form, they are restrictive by the nature of their mass produced design. By having your cylinders ported, the mechanic will enlarge these ports, allowing significantly more flow in combination with changing the cylinder timing for improved power delivery characteristics. This work is not unlike dropping in a new cam in a 4-stroke motor. The port job you have done is specific to the type of riding/performance you want as an end result. Exhaust: Pipe design is specific to how you want your power delivered and where you want it relative to RPM. Remember that Flow and RPM are requirements for Power!! Some are tuned for lower RPM use, some shift it higher... The reason I broke this into 3 parts is because you shouldn't only modify one area...you should do all three for best performance. Imagine these 3 components were 3 separate pieces of pipe of different sizes. If you had 1 larger and 2 smaller pipes, you would still have the restriction of the 2 small pipes, regardless of how huge the large one was. Same result with any combination. Picture joining a 2", a 1", and a 1/2" pipe together. It can only flow what the 1/2" pipe can flow. So what you are trying to do is open everything up in balance, even everything up, and get max HP or desired torque curve!! So as you see, just opening up or improving one aspect doesn't give huge gains without improving the other areas. If you are not going to port your motor and just focus on exhaust/jetting, it seems the Toomey T-6s are designed for that level of upgrade. Your current pipes are already a good choice if you plan on doing more to your motor. If you are racing on a track, how will OOF pipes handle a crash? Pipe selection is a balance of performance based on other mods you are doing, so it can be a component complimenting package. If porting is in your future, then list what you are planning on doing, as well as the intended use...MX-trails-duning-asphalt-etc. These particulars will make a difference as to what to buy. :thumbsup: One other thing to consider is the human nature aspect...that being everyone wanting to race you up the hill because you are sporting OOF drag pipes. You had better be able to back up your game!! :geek: Hope this helps....Jay From SanD iego. Edited August 23, 2007 by jayzx750 Quote Link to comment Share on other sites More sharing options...
