I can't wait to see these results.

Duncan Fatboy 4. Can you test one of those?

YFZflyer · 12-29-2006, 12:45 PM

If you want to send it to me... PM me and I will tell you where to send it.

Kenneth: All pipe will be jetted when installed, not just slapped on there and dyno'd. I need to see what each pipe will make the best it can on my build, because after all.... I am looking for the best possible pipe for my build. For me I am looking for a pipe that has more bottom and mid range then the RW I have now, and also good top end. Then I would like to see which drag pipe does the best on my build.

Also maybe I can (if I remember) over lay the best HP pipe over the lowest HP pipe.... Peak to Peak
Same for the best HP drag pipe over the lowest HP drag pipe.... Peak to Peak

I want broad power, not just a ski slope to 10,000rpm where it all of a suddens makes good power.

pharit · 12-29-2006, 06:13 PM

i don't have one just hoping you dyno one so i know which one to get. lol

**Terse** · 12-29-2006, 07:12 PM

Just so folks realize that this pipe will be done on my motor. It is considered by some to be highly modded, and not a "bolt on" bike.

High comp 14.1
Ported
Cams
Big carb
Best Intake

(IMO)

etc etc. The results will be different on a piped and filtered cam mod motor.

whylieiride · 12-29-2006, 08:35 PM

So your using a FCI right?

**Terse** · 12-29-2006, 09:14 PM

Alpha HAHA

If I wanted a drag only or top end only set up, I would run the RW ported if it will fit around my rear Elka somehow. But I am looking for more low/ and mid with the least amount of top end decrease as possible.

Yes I am using a FCI, but it is my FCI from my intake test.

i am just kidding if i could afford the down payment i would get the fci, i mean if they offered me a good interest rate

**fatboy** · 12-29-2006, 09:28 PM

Fci will be the most forgiving for all these pipes when tested. The ported Ron woods may work well with one pipe but will do real bad with another. Its do to the tune length. Fci tapered design simulates intake runner length. Thats why you get a better curve and make power faster with the FCI. Sorry didnt mean to distract from the topic.

Corey looking at the graphs, gytr does real well against anything. The Nmotion still out peeked it though. GYTR did have more low to mid though than Nmotion. If you drag I would go Nmotion. Hopefully we will have a stock bike here shortly so i can retest them on a stockbike.

**Terse** · 12-29-2006, 09:50 PM

Fatboy you never distract from topics, add anything any time!

That is dang good info about the gytr having less at peak then the Nmotion but more low to mid

:

: I would not have guessed that. I actually thought it would have been the other way around. Seeing how the Nmotion has a shorter can then the new GYTR.

better velocity in the new gytr, i think that the fci and new gytr would be a great combo for quick low to mid power, but for full drag and topend i dont think that setup would be the best. just my 2cents

Again this is my setup. with my certain cams, degree'd a certain way. Were not talking alot more at peak either, maybe a 1hp at best. The Nmotion is a nice pipe and really works well , to me its old faithful. But as far as sound vs performance gytr is a nice pipe.

What are you running now?

I havent been running anything becuase all my bikes are apart. I havent even tried the gytr out in the real world yet, just on the dyno. On the drag bike il be running a the new Nmotion out of frame pipe. Hopefully! It should be a megaphone design with a core in it. I have three pipes Rossier, Nmotion, and gytr.

mr331 · 12-30-2006, 05:46 PM

All the above talk about Nmotion and the new GYTR. I'm currious how the Sparks Big Core (no silent core)will fare in this mix? Simply power numbers, never mind noise.

I will have at least 1 sparks big core SHORTY no silent core or SA to test. The Sparks shorty runs around a 9" can.... just like the Nmotion 9".... sounds fair to me

I am not testing for noise or DB or SA or anything. Just power. Smooth power and peak power.

Anyone have a new GYTR for me to test? I do not think that I will be able to buy and get in time for the test a GYTR.

I now return you to your normally scheduled program

Dyno pipe testing on a raptor makes no difference for a yfz. The raptor gains way more HP then a yfz will, as the raptor is corked up more then the yfz is stock for stock.

This is a yfz test with my mods, not a raptor test.
