54/44---silver spring results

"I simply deal in real world results, not just a peice of paper telling me how much power I have."

just got off the phone w/ jabber800. said both he & valin have tested w/ the bender round srx can. found no loss or gain on the radar gun. he also stated that if he could run it in stock class he would. sounds like the radar gun agrees w/ the piece of paper!!

So with this, you have now confirmed:

1.) the "dyno" results of 4-5 hp midrange and 2-3hp gain on top dont make any differance because the sled runs the same mph!

2.) your "HUGE" sprung weight loss also made no differance in results

so again, we find ourselves holding a peice of paper, $200 less in our wallet with no gain in performance and our buddy just ran the same mph with his stock muffler.

but you get to sound cool!
 
I have no reason not to believe Bob's statement on the performance of the Bender silencer.. I have seen first hand some of the work he has been involved with at dyno tech.
We did not see any difference when we ran the silencer on our 700, but I didn't expect to see one either. The gains are very small and alone will be very hard to read in what you are calling the real world testing. As for the statement on not seeing the results of the 2-3hp gain and the reduction in weight. I can't imagine seeing that on the track!! My 700 with my son on it at over 220lbs with gear always ran within 2 to 3 mph of the same sled with a 140lb driver.(2 to 3 mph with an 80lb difference) How are we ever going to see a gain in speed with a drop in weight of only 8 lbs?
I like the box it makes for the sweetest sounding tripples around and that alone is worth having it..
 
ya but Dan , if a maufacturer , advertizes a hp increase of 3 hp , its because they engine dynoed it , correct ? If they were to track dyno the same item and have 0 increase or field test it and say no jetting or clutchng required cause " you wont notice the power increase" then thats what they would have to advetize as a sales pitch and it would not be very successfull to say the least , there is no question that the information given is accurate but simply that it has been manipulated by mfg.

The avg sledder buys these products , and then beleives he has added hp, and given the opportunity will want to fist fight to defend his purchase cause thats what he was told by the product distributor ..

Aaen claims his pipes make 8hp , do you think they would say such thing and be suseptible to false advertizing ? no thell just tell us we dont know how to make them work ...or we need reeds or this or that to complete the project ... cause there dyno sheet says it does

On the same token , i port an engine for you and say , it will make 8hp more , but you wont notice it or , need to clutch , .....i already know what you would tell me

But they sound is SO SWEET. I'm thinkin of pickin a used one up just for a little fun every now and then.
 
Many variables with putting the power down Vince. My point is if the box made 3 hp or lost 3 do you think we would see it in a radar run? Likely not. You know how much work it takes to be 2 or 3 mph faster that the next sled. Just changing the stock box for a Bender can is going to be very hard to see any difference.. I have just had really good results with the Bender can and have many test runs to back it up..
 
I TOTALLY RESPECT EVERY ONE OF YOU GUYS, AND OPINIONS ARE LIKE YOU KNOW WHAT, SO HERE IS MINE ONCE AGAIN. THE STOCK CAN ON THE SRX IS THE BEST IF YA WANT TO HAVE YOUR BEST PERFORMANCE. ESPECIALLY AGIANST A FAST F-CAT. IF YA WANT TO BE COOL, CLOSE TRAILS, GRAB ATTENTION TO THE COPS, AND LOOSE TO THAT F-7, RUN A AFTERMARKET CAN. 3:16 (yammie tony)

Vince forgot the cylinder today.. I will get it for you tomorrow morning.. I have to finish a set of cases in the morning before driving to SSM so I will be at the house.
 
I now (finally) have 8DN's with 4.5 grams in both, Y-S-Y spring, 54/44, silver at 6/2 and from a 10 mph roll it absolutely rocks all the way till the speedo is burried and the 03 F7 is behind me! From a 50 roll it isnt exactly a dog but far from perfect. The back shift was not good from 50-70 but it was over 30 degrees too. The next day it was high 30's and the snow was really crusty and heavy and I couldnt turn over 8300 and it was a total dog (at times). Overall Im pleased especially considering it was in the weather and my 0-60 greatly improved compared to the stock primary (8Dn's and stock spring).

Day 1--Rpm's are 8500 right on the nose. Rick Hacker said keep it at 8300 but it feels faster at 8500...

Bach shift is suffering some but you can't have the best of both worlds,you need to tune the sled the way you ride 90% of the time.

80 is a good wrap,83 to 85 is golden,run 'er!!!! and spank more ditch pickels
 
or is there too much weight from going to the 4.5 grams in the inner hole on the weights... did you have same springs in before, but with the 3.8? how did it feel then? crisper?

Yes before it did have better back shift and was crisper but the acceleration wasnt even close to now with the inner 8DN hole at 4.5 and the ysy spring. Before that same F7 would jump me and pull away by 3 sleds and it took miles for me to catch aand eventually pass him. Now were either side by side or 8 out 10 times I would get out by half a sled and stay there and then after 100 I would easily walk away. Whats odd is now my engagement is crazy low but my low end is much stronger. It feels and sounds totally different with the ysy and 4.5 inner rivets. The engine and pipes have different (deeper) tone now. If I make any other moves, it might be a diff prim spring but otherwise I like this set-up. ;)!

Also my belt and clutches are barely warm but........................even with the speedo pegged and beating a fast F7, Im still 1/4" from the top of the primary???
 
belt doesn't ride to the exact top of primary. it will always stop about where you're seeing it, unless you machine primary for overdrive. also, the reason your engagement is soo low now w/the y/s/y, is cause of 35kg preload, instead of 45kg like w/stock y/w/y.
 
Like mopar said thats about right where it rides, if your a light guy run the ysy if your a heavy guy run the www difference is around 500 rpms.

a srx needs all the help it can get off the line with out spinning and plant power i like running a lower engagement to help with that issue.

i would leave your set up alone.

I agree! It actually launches harder--a lot less track spin. Im 195 undressed so Im not 145 light but not 340 heavy either I guess...

The 50 -70 backshift might be an issue the way we ride but otherwise below freezing on cold days and low humidity, this set-up rocks. Above freezing on warm days it just cant pull it.
