Hans Snorkel Undisputed Test
Can somebody run a stock zx12r and do 5 top speed runs at maxton...Then bolt on the Hans Snorkel with no other changes and do 5 top speed runs within a 30 minute window of the first 5 runs..Make an average of all the runs and see which one comes out on top..
Fearsome K always seems to be in the minority but he sure does back his SHIT up!! Ever since I received my letter from Keith Parnell I'm sold on whatever he says...

Question: How many cfm's do the 46mm throttle bodies flow? How many cfm's do the ram air intake runners flow? Is there a variance in these numbers?

What's your point? What if told you that the inlet valves flowed less than either one? Would you still care?

I thought I remembered that blais cycles said that the throttle bodies flowed more cfm's than the runners themselves.. I could be wrong.. Im talking about air flowing through throtttle bodies not the intake valves themselves..
Another question: Kawasaki quotes from the silver book that if they "didn't have noise restrictions they could probably bump it to 210hp".. what noise are they talking about intake noise or exhaust noise? Just a question..
Thanks,

Of necessity, when the throttle bodies are connected to the runners and intake valves, the same amount of air flows through each.
The question is whether the restriction of the throttle bodies is significant relative to the restriction of the latter, and then if so, how significant.
I believe if you do a search on the Monster Snorkle, while won't find the exact good test that you propose, you will find sufficient reason to give it no credibility.
EDIT: Psycho already bumped it for you.

If you provide the intake I will do it at the April meet.

Of course Trenace, if they are all in the flow path. But, the maximum flow is determined by the most restrictive part of the path........
What do you think that would be?

What is the fix for the leaky chambers? Do you seal it with marine grade (GOOP) glue, epoxy mix, gas weld, other? TY

Thanks fish, I have plenty tubes of 56k. I rather use a glob of V.92 though. It dries faster.

Doug,
If you are implying bigger valves on the 12 give better performance, you are "flying in the face of conventional wisdom"(even on a built 12) 
Most experts seem to say that the 12 (and the Busa) have perfectly sized stock valves for NA motors, even for my 1427 NA 15:1 motor.
I have NOT increased my valve size based on this expert/conventional wisom, but if you have thoughts in this direction, i'd sure like to hear 'em, yep.
On a related note, I went from stock 46mm to 48mm TB's and definitely got 3-4hp; did a sequence of dyno pulls over 2 weeks, same fuel, same motor, pretty close to same weather.
1. 46's, pulls,
2. put on 48's, pulls, gained 3-4 hp
3. went back to 46's, pulls, lost 3-4 hp
4. re-installed 48's, pulls, got back my 3-4hp

The intake valves on a zx12r are 33.4mm HUGE forget it

Gained 3-4 hp.
Is that "peak"? How did it affect power "under peak"??

3-4 hp very nice, would be interesting to see that curve.

I don't have the curves in front of me, but from my log:
9-Sep-05: dyno, Tejas dynojet 250: 213hp STD max w/48's , will try w/46mm TB's, 11 pulls
13-Sep-05: dyno, back to Tejas w/46mm's; lost 6hp peak wrt 48's (207 STD vs 213 STD), 8 pulls
30-Sep-05: dyno, SPAZ's mobil dynojet 250i @ Memphis Prostar; 48's back on, but was way rich, made 217 STD after a bit of tuning; est 20 pulls total
The question I always wonder about is just what is the difference at speed; 1/4 mi mph tells all, but various gremlins have prevented this test.
I am convinced there is benefit for my motor so i'm running the 48's (thx MM!), no more tests w/46's; i am not gonna screw with em no mo'.
I will however run a test of Hans vs OEM this spring (at the track)

Still showing "Peak" #'s there entropy... and VERY nice BTW!
How about some #'s at 6,000 or so?
I agree, 1/4 mi tells all!

The Texas Mile would be a good place to test the big snorkel also. Heard
a rumor Entropy might be attending in October. Bet if some one bought
Entropy the snorkel he would not mind testing it for us all.

Entropy,
No, that wasn't my point at all. I've been pretty vocal about bigger valves being a waste of time. We're in total agreement on that. As for the bigger TB's, no problem there, either especially on a big 'un like yours. My comments were to point out the futility of this mod on a stock size engine with stock cams at stock available rpm.

Doug,
ahhhh, that's what i thought you'd said much earlier about valve size. I's hell being old and not remembering who said what
