124" build...I'll let the cat out of the bag

[AllanW]

I'm interested in hearing what pipe it would take to help Rays motor. I always thought the zilla was a good choice on big motors. What are its limits? Is the collector to far from the port? Collector diameter? Head pipe length to long or short?
I'm all ears to this topic because exhaust tuning has had my attention for quite some time now but I can't seem to figure out how to approach wave tuning, over exhausting, etc.   

It doesn't help that I have this same pipe/cam combo on my 117. Haven't had it tuned or even on a dyno with this combo.

me too...I'm all ears

Why don't you try the 5" trapp can?

[strokerjlk]

Took some doing but I got the fang 3.05 muffler on the zilla headpipe .
I have seen enough to tell , it will take the dip out for the dip police .
It will sacrifice the peak tq a few . With a little tuning  it would pick the hp up on the big end another 2-3 . Not worth the time /effort / money .
The trapp ain't gonna make anymore hp . And probably lose tq .
I can de-tune it a little and make the graph real smooth though . It would make a pretty 138/138  sheet .

looks like it's falling on it's face @ 4500 for some reason 

Looks like it's pulling fine from here.  You'll never feel it in the pants.  The HP keeps climbing just fine.

I agree, Jim should have let him ride it before he ever saw the sheet, All I can say Ray, is you better hang on!!! I highly recommend a riders back rest...

[HighLiner]

I don't know if would apply but I think Drago's offers a money back guarantee if his pipe doesn't make more power.

This isn't about that .
It's easy to see the ZILLA headpipe with FANG muffler will make more hp than the zilla exhaust .
So yes a fang would make a couple more HP on rays bike . Is it worth the price ? Hell no .

[strokerjlk]

I just rode the bike . WOW it's a azz load of fun. Ray you can pick it up next week.
Your gonna have to Velcro your azz to the solo seat now .
I ain't kidding ... To launch the is thing in the first 2 gears , there is no way to let it eat all the way and stay on the seat.
You need to do your seat like this

[Admiral Akbar]

I thought the Fang pipe baffle was louvered and the zilla was perforated..

[NCTURBOS]

Even on Dan's (TXCHOP) 117" powerhouse they modified the Wegner exhaust to max out it's potential.  It's all part of the game, you just need to decide when it's time to call the final play and make the score final...

well men...it is basically a 142 square motor off the drum. It will fulfill my needs for now...for sure. If I need more than that on the street...I must be 8-up...wait a minute...I already am   
Thanks for another excellent tune Jim...I'll bring you another case of your favorite beverage along with me to drop off when I pick the bike up tomorrow.
I'm thinking that this motor just fell a little short in the compression department for what I originally sat out for. I wanted 11.32:1 and I think I'm right @ 11.11:1 now. I said in the beginning that all the figures were done on the Big Boyz calculator. Either the pistons are not cc'ing out...or the heads. I'm leaning more towards the pistons. Larry said he got the heads where I wanted them...so I would have to believe him. I had to open up the valve pockets a little on the pistons intakes for clearance...which according to the B/B calculator, it says I must of lost 2 cc's on them to get me at the 200 ccp's that Jim is showing.
I'll have to investigate into the possibilities of getting a set of domed CP pistons for this motor later on if I need to get more 8-up with it.
Or maybe a set of S&S B2's with their domed piston to match 
Right now...142 SAE hp/tq and 200 ccp's sounds like a nice everyday rider to me.     

[Jaycee1964]

Now you gotta put it on the bottle...   

[IronMike113]

He isn't going to need a bottle, first he is going to have to get used to it on the bottom end first Strokerjlk isn't bull chitin when he tells you about the first couple of gears,they hit hard and fast,I was think maybe a harness if you get it hooked up,PWmorris said it best practice,practice,practice, than look out boys there might be a Boss in town

you are correct

dont get caught up in the 2-3 hp game!

you have a very nice build and tuned bike.it will be a handful for sure.

forget about the sheet.

its hard to do,i know every time i dyno something and it falls short(which is normal for me)
i just get all caught up in the # game!!! happens every time.

the #s are only a small equation to the entire tune and build.

you made just a tad more power with a cam swap but gained less motor noise and a better behaving bike.WIN WIN.

i hope you enjoy your bike and stay positive.

Travis 

[strokerjlk]

Actually he lost 3 hp and gained 8 tq
He moved this power band way to the left . And didn't lose anything below 5250

The green is the 117er disregard

[Durwood]

I wouldn't disregaurd the 117'er, he picked up 14 torque and 9 horse over it, and only spent $1200 to get there after selling the other engine...Nice gain

I know guys that have spent more for less..Good on ya Ray

Now send me the tool box keys again

[Ohio HD]

Looks really good Ray!

If you do look for some custom CP domes this winter, I'd be so curious to see how the Feuling 630's would run at 12:1 compression.

[Tattoo]

  I would like to see that as well. I got my 120" project set at 11:5.1 with the 662-2 cams. I hope its not to much.

[cruzmisl]

Yeah but like me after two weeks you'll be looking for more

ok Darren....       but what if...  ahh never mind   

[HD/Wrench]

I would like to see that as well. I got my 120" project set at 11:5.1 with the 662-2 cams. I hope its not to much.

yep same here ohh wait my is set at 12.3 and running 266, 640 673 cams lots of 6's there getting old  no sexy pipe with money back warranty just a beat up zilla test pipe and will give the mega zilla a run or two as well.

I think once you ride it, you will enjoy this set up for everyday use and for whatever else you want to do with it.         I know I do.

it'll go more 

[FXDRYDR]

Damn nice job - hat's off to all involved. 

You have a potent ride Ray - a couple more here or there isn't going to be noticed or worth the cost, IMHO.  Compression is reasonable, runs strong - you can go anywhere, anytime and not sweat the load.  Resist the urge and enjoy the ride... (for a while anyway!!)    

[bulldog]

Jim, if a person is running a 120", would you recommend a Zilla or Fang?
