If only you guys new what you were missing with running a set of 28mm flatslides instead of those shitty 2 into 1 intake setups.

When you build a low-mid motor, the main idea is not to be concerned with lots of peak hp. Its low-end power, torque backup, and acceleration times. Putting huge carbs on a motor and dynoing it with a low-mid pipe is fudging numbers. It makes more power on paper, but kills acceleration times, and makes it harder than hell to jet in the real world. So, until this R&D takes a turn to resemble a "real world" low-mid setup that is optimal, this whole thing is a joke in my book.

The 4 mill motor has an 188 degree exhaust duration. We have another 4 mill with a 186 degree exhuast duration that peaked those pt mids at 8,600 rpm. We also tested them on a 7 mill cub motor that had been resleeved with the all the exhaust ports lowered and the pt mids on that motor peaked at 8,650 rpm. We use a crank dyno, its a lot more accurate than a rear wheel dyno because it measures hp on the crank. It also has an engine break on it. All these charts you have been showing me where rear wheel dyno charts. Here is your so called trinity low-mid pipe compared to a dynoport pipe. The chart is in a time format. But it shows you the delayed acceleration time on the trinity pipes. They come on roughly a 1,000-1,500 rpm later than the dynoport setup does. They dont have the acceleration curve the dynoport has either. Thats saying something too, the dynoport is a piss poor low-mid pipe at best.

I have charts, but they are all winpep format. I have some printed out, and some jpeg snapshots of them. I dont have a scanner anymore, so I would need to take a picture of them and then load them into photobucket. Im looking at a chart right now for pt mids on a 4mill. We ran pro circuits on it as well. HP peaked at 8,750 rpm at 78hp with about 1500rpm of torque backup. The same motor with pro circuits made 82 hp at 8,750 rpm with 1500 rpm of torque backup. The curve leading up beat out the pt mids with by at least 2hp all the way from the bottom to the top. Trinity developed the Stage IV pipes around the Stage IV port work. They are a mid-top pipe as is the port work. They rev up-wards of 10,000rpm on a Stage IV motor. Pro circuits are a low-mid pipe designed around trail riding and mx racing. They peak at about 8,750rpm.

So what does that prove? You have two dyno charts off of a rear wheel dyno? I think all you know about pipes is charts you look at on the internet.

I think your high as a kite. Pro circuits come on even sooner than pt mids, make more power everywhere, and then sign off at a lower rpm than the pt mids do. So do you believe the 2 into 1 pipes is a low-mid pipe?

I have a hard time believing you know what bottom end is with a setup like the one listed in your sig.

No I dont, I have dyno sheets for both and they are very different pipes. The trinity pipes are a mid-top pipe, and a shitty one at that. There are better mid-top pipes out there than Stage IV pipes.

from about 6400 rpm down the 2 into 1 carb setup makes about .50 more ft lbs of torque than duals. At 6500 it jumps to a 1.7 ft lb difference in favor of the 2 into 1 still. At 6900 rpm the duals have the 2 into 1 beat out on torque by .25 ft lbs.

I know they work with the intake boots, I dont know about the airbox boots. I run them, and I am pretty happy with them. When you get them, they have to be setup for a banshee with the right needle/seat, slide cutout, nozzles, main jets, pilot jets, and needles.

Do you know how banshee hill became an established trail?

Getting rid of the 2 into 1 intake will get you 5hp from mid-top with pc's. You will only give up 1.2 hp on the bottom end.

Pro circuits are nothing like T5's. I imagine its the same because of the amount of fuel and air your moving through the motor (airbox inlet cfm amount). I imagine the mid-top pipes were the ones that just needed 1 size larger compared to the low-mids.

which plug came from which side?

I cut down a tree with an AR15 today, so your not gonna get much compassion from me with this topic. I will ride in the area where I am supposed to, and I will follow the rules. There isn't anything in the rules that says you cant blaze your own trails in bounds.

what ocatne and type of fuel?

I hope its not .080"

They are a pretty reputable snowmobile exhaust company. They are not the same company that does car exhaust.

I think blaster pistons work.

So I had someone tell me SLP Banshee pipes make a ton of lower end hp. Then I went to their website and saw this. http://www.startinglineproducts.com/catalog.cfm?pageID=detail&catalogID=1&catID=49&productID=887 Discuss.

spacers help if your running somethin bigger than the stock sized overbores, or if your running a stroker setup. Its only a midrange gain also.

Matt already has numbers off of it with dyno time. It works better than the other single pipes out there, but its still not near the peak hp that low-mid twins can achieve. It does however sound like the bottom half of the power range is quite competitive, maybe even better than what the low-mid twins can do. It sounds like for a pure trail bike, it could be the way to go if the motor is setup around it properly. This pipe is not meant to be for a drag setup, or necessarily for what MOST people consider a dune setup. It is meant for a trail setup, on a trail motor, in a trail bike. I talked to him today for about 80 minutes, and I have a good grasp around what he made the pipe for and what he envisions it being able to do. It sounds like he has got some more testing to do still though. Honestly guys if someone just posts dyno runs, the majority of you are probably not going to be impressed by it. The pipe has to be ran against something comparable, and the setups would have to be analyzed to see where each one makes a differece comparitively. Not to mention they both have to be setup around a low-mid trail type setup motor.

It wont make a difference on that motor.

I am completely baffled as to why you hadn't answered any of the questions that anyone has asked. Instead you keep popping in and out with pretty much useless banter. I keep asking for answers to the questions I asked (which is all I am interested in), but you keep telling us your not a salesman for Matt Shearer and your working on setups for the pipe. So the only thing so far you have answered was that the pipe cleared the pod filters on 38mm pwk's. Again like I said before. You made this look like this is in direct conjunction with Matt Shearer, as you used his logo on your video. It wasn't till last night that you made it evident Matt had no association with this, so obviously I have had no chance to call him yet.
