Trinity Pipes

[SLORYDER]

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.

 

I don't believe you have enough research o say they peak at 8,700 rpm. You would have to do several tests using several exhaust durations to find out where the peak rpm is and what the hp number is at that rpm.

 

That was their peak on that particular motor..

On a stocker it would've been over 1,000 rpm sooner.

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.

best discussion I have read on this board with out turning into a pissing contest. I saw some good points both ways.

[SLORYDER]

I could be wrong but something does not seem right about that trinity pipe dyno run.

Also look at the average hp once both pipes are "on"

Very very broad power with good rev out..

[Snopczynski]

That was an acceleration time run sheet, and that trinity pipe lost compared to a dynoport pipe. Thats pathetic, because Dynoport 2 into 1 pipes suck. Not to mention the supposed low-mid trinity pipe made only 2 more hp and 4 more ft lbs of torque compared to the dynoport. Like I said the pro circuits already smashed that hp number, the torque number, and they accelerated faster than the dynoport pipe did.

 

So now I put up the chart and it has something wrong with it right! Jesus!

Are you autistic or something guy? Chill bro before you hurt yourself.

 

A couple of things I noticed:

 

1. The bike with the dynoport pipe appears to be more modded; the Trinity run shows only pipes and filter, as opposed to the former having porting timing carb ect.

 

2. That's just a weird power curve it appears the engine is not calibrated to the pipes.

 

3.The trinity pipe provides roughly double the average horsepower than the dynoport pipe.

The bike with the trinity pipes would be much much quicker than the dynoport bike.

I am actually impressed with the trinity pipe now.

 

Thanks!

ok, i'll add my 2,000,000 cents now, lol......the key word on that chart is TIME. it shows that the dynoport came on real quick, pulled, and dropped of, as to be expected from any 2-1 pipe. then the trinity took it's sweet ass 3seconds to come on, and pull for 2 seconds. once again, forget about the hp and look at what the torque curve looks like. still peaky, even though it's hard for you to visuallize by looking at a time curve, not rpm curve. for all we know, it could have been pulling near same rpm's for a second

Edit: I see your point.

I think your example is very exaggerated, though.

i wouldnt compare dynoport pipes to anything but STOCK.. pro circuits with a real exhasut like around 198* and 128* transfers hae something a lot of other trail pipes DONT overrev!! they will hold rpm's far longer after the HP peak.. and sometime not having to shift at the end is what makes it all worth it..

 

i just bought a bike with a 421cc stock cylinder motor in it it has trinity inframe pipes and honestly they run really good. BUT the bike has hours of dyno time and custom mapped ignition, it made around 80hp and 50ft+ of tq... ( more tq that a 4 poke HA) its fun to ride but almost too fast.. its kinda hard to jump the acceleration is almost too quick in the hands of a "pro rider" i think it could be very lethal. but they would have to have a LOT of stamina..

 

as far as betting a guy that you can race him if you have any doubts better use extra money..

But theoredically, when looking at an RPM based dyno graph who's to say it doesn't stay at 1 rpm for a second or two?

 

I believe my assumption about the trinities having 4x the range of the dynoport6s was accurate.

[KlotzBanshee]

Despite what some of you say I really like my Trinity pipes. Agreed, they aren't for every situation or riding condition. But, they pull very hard on my bike and do very well in the dunes, open tails, and fire roads I have ridden. I don't know or care about dyno numbers on each pipe, but I do know I have passed by more than a few banshees with FMF's, PC's, Pt's and T5's. Could my banshee have been set up better or have more mods? Sure...but I didn't slow down to ask them.

 

I will say I do not like Trinity as a company. They are over priced and their service sucks, but their pipes aren't as bad as you paint them to be. There is also something to be said about being the only stainless steele pipes around. You can have the chipping chrome and rust issues you get with the others.

well, that's just it- a dyno run based on rpm will disregaurd that 1 second hold and not progress the chart, if that were to happen.....the computor factors it all.

[SLORYDER]

 

AK Heathen:

If the engine is not accelerating, how will the time based grap post a horsepower number?

The graph shows the engine PUTTING DOWN an average of 42ish horsepower for over 2 seconds.

Now, if the engine was not accelerating-that is if it were at 8000 rpm say for 1 second, then the graph would drop off and would show zero hp.

What you read on that graph is the amount of hp(acceleration) at any particular moment.

Where the graph drops off, then goes up again, is where the acceleration slows, but is still accelerating. Like I said a lack of acceleration would be a vertical line.

 

If it were at 8000 rpm for one second there would be no horsepower shown.

If bike (a) puts an average of 30 hp to the ground, from now until 5 seconds from now, and bike ( puts down 40 horsepower in the same time period, bike ( will have covered a lot more ground, gearing being the same;

 

horsepower = acceleration.

I am in love with my Trinity's... and will never get rid of them. They pulled hard on a stock stroke, stock ported bike.

 

Then they pulled hard on a HJR stock stroke ported bike with 33mm PWK's.

 

And they are hauling ass and kicking ass on my 421 4 mil HJR ported cub, with 35mm PWK's.

 

They are good pipes. Maybe I got a good set? I don't know. But they kick ass IMO.
