2-2 exhausts tend toward torque, 2-1 and 2-1-2 exhausts tend toward horsepower. This motor is engineered for big torque so it's hard to overcome with bolt-on mods.

Consider Ivan's ECU.

In the end, rider skill and even luck play a big part. Your mods give you advantage but you cannot judge based on one casual street race.

 

Not arguing with you, but I thought that I've read differently on that. Actually, the opposite. The 2-2, being more open and free flowing, tend towards HP, while the 2-1 and 2-1-2 tend towards torque.

 

^--- what he said

so, you both have Warriors and will win the crusier game against others. You both have equal penis size, congrats!

 

I don’t know. For discussion fun, let’s say it’s definitely the bikes: It’s neck and neck and then one gently pulls away at 80mph. What might make that difference?

 

Among other things, 2-1 and 2-1-2 motorcycle exhausts advantage scavenging opportunities. It's why the Yamaha Speedstar and the Propipe exist.

I am always open to reading materials that counter this, its counter-intuitive but it's all about the mods, right.

 

I got that completely wrong, brother. I'll blame it on the Rum.
Like you said, it's all about the mods, and I have so many parts at home waiting for me to have time.

 

First off both of the bikes are similar so the outcome will come down to......
Better tune?
Better driver?

You really want to beat your friend learn your power band and the optimal shift points. Learn to speedshift/no lift shift. These 2 things will have you putting bike lengths on your boy.

Now if you go chasing hp then you will have to go with a 2 into 1 exhaust, spot on tune, Ivan's flash, cams to extend the powerband......

 

Yup. And besides pipes and other things, like you mentioned, there’s Ivan’s flash. It’s a good bang for buck performance mod.

 

Also a Barnett's Spring conversion and
A 2 or 3 plate mod....

I knw that doing the Barnett conversion and plate mod really REALLLY help my warrior alot..

I'll definitely have to do some digging on the forum. It was no big deal win or lose, just upsetting in a sense. All fun and games. Ivan's was next on my mod bug list for sure. Not planning on becoming a drag racer by any means, but the power of the Warrior is just too fun not to tool around with every once in awhile.

 

Your exhaust is killing torque a 2X1 = best exhaust for torque.
If you like your pipes tune them for torque, get some cage tailpipe reducers that fit inside the pipes & reduce the outlet size to 1& 5/8 or 1 & 11/16. Sheet metal screws on the backside & bottom of the pipes will hold the reducers in the pipes. The tailpipe reducer is inside the small slash cut pipe.

Suggest a 31 tooth drive pulley.

 

Like the others have mentioned, I'd have Ivan's flash you ECU. Makes the bike a lot smoother and unlocks more power is the best way to put it. Your ECU with Ivan's flash will allow you to go up to 5850 RPM and it removes the governor of 125 mph. It doesn't give the bike any more power but it lets it use its full potential.

 

Awesome insight from everyone. I appreciate it. Ivan's might be my next mod. Churkey I've done a little reading on the 33T pulley, but haven't even thought about the 31T. Maybe I'll have to give that some thought and read up on it in the forums. I do more out of town and highway riding, thanks to living in ND, so the 33T caught my attention.

 

Your Samson Street Sweepers are known for style and sound, not power. I would guess that is your biggest detriment. Get some longer 2-2 or a 2-1 for performance.

I tried the long Samsons, I think Straight Shots??, against my ProPipe. The Samsons looked good, but were deafening, and had less torque than the PP.

The stock Warrior engine doesn't really spin rapidly enough (5200 rpm) to take full advantage of 2-2 pipes. If you were racing, sure, but on the street, I doubt it.

 

Sometimes these terms are not describing what people think. Plus the torque range can fall at different places along the rpm range. And that place can be moved by hardware like for example baffles and exhaust gas flow rate and exhaust scavenging and . . . Of course . . . Motor design.

"Power is the rate of completing work (or applying torque) in a given amount of time.

Mathematically, horsepower equals torque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is the mathmatical constant."
