I was finding info on new chains and my options surrounding the situation. Of course D.I.D. is very popular. I also found a product called 'Driven Racing'. The products looked really nice...

www.drivenracing.com

Maybe a 520 conversion w/ a black, yellow, red chain + sprocket.
BTW my bike is a Yellow 04 Svs w/ black accents, and red SS lines.

What do you guys think?

i did a little bit of research into chains with my mates at crescent and they said that for a bike making as much power as the sv, theres no point in getting a 520 conversion as the weight you save wont make any difference, they're desinged for the gsxr's/r1's/blades/etc etc.

changing the colour of the chain doesnt make any difference so you might as well go with your favorite colour or whatever you think looks best on your bike.

if you get a new rear sproket make sure you change the chain and front sproket as well (ideally you want to change all three if you change any one - that make sense?) as otherwise you will be working worn metal and new metal together and they will wear out super fast. manufacturers i would recomend for sprokets are renthal and talon (possible afam but maybe not)

chain manufacturers are DID or DC chains

on the subject of brakes, if you want to uprate your brakes a bit, rather than getting ss lines that are only going to strengthen, not improve, your existing brakes, i would spend a little more and get a new master cylinder as it will push more fluid down the hoses and make you stop faster, the brembo cylinders are nice. order i would go would be, new cylinder, new calipers/pads, new lines, new rotors (then more new pads for new rotors)

this is just what i would probably do and which manufacturers i would choose, but ultimately its up to you

hope it helps

Trick ;)

Thanks for the info trick. I already have the SS lines, so I think I'm gunna keep them ;), but I see what your saying.

Untrue.... Doing the 520 conversion yielded 5 mph and 4 tenths quicker through the 1/4 mile for me. At the same time of the conv. I went from 14/45, to 15/47 (yes, i know my sig says 15/48, but that changed just recently) which is a steeper ratio, and I still did better.

With the original conversion I did, I saved 1 pound over stock. With the setup I have now, it's a couple ounces lighter than that (new rear sprocket is lighter than the original 520 rear sprocket).

Saying that it won't help, is like saying some ultra light carbon fiber wheels wouldn't help. Lighter weight, especially in anything rotating, is the same thing as increases in HP.

edit: You can say the quicker ET through the 1/4 was due to me becoming a better rider at the drag strip. However, the increased MPH has very little to do with that. Increased MPH means increased HP (usually).

TRaGiK, what brand did you use for your conversion?

Also, did you happen to take a look at that Driven.com website?

Not saying I don't believe you, but It'd be cool if you could say your 1/4 times and top speed were increased without the gearing change. the gearing change will affect both of those.

actually...isn't a 14/45 damn near the same gearing as 15/47? why the change?

14/45 is 3.21 ratio, and 15/47 is 3.13. It doesn't sound like much I know. This is not enough difference to warrant the 5 mph increase. In fact, unless the gearing is TERRIBLY off, changing the gearing does little for trap speed...and I've never seen it make 5 mph worth of difference (most of my expereince is with cars, but it's the same principle).

Also, I went to the drag strip last nite. With my current 15/48 setup (3.20 ratio - nearly identical to 14/45), I went 12.57 @ ~106. 1 tenth slower than with 15/47 (was my own fault for going slower - crummy launches).

To offer more proof that less weight = more hp:

My buddy had a 97 Mustang GT which had 17x9 Cobra R wheels on it...VERY heavy wheels meant for road racing or bling. With the car setup like this, it went a 14.5x @ ~95 mph. The ONLY changes we made to the car was installing 15 inch rims (15x8 on back, 15x4 on front) and changed the oil to synthetic. Back to the drag strip, the car ran a 13.7x @ ~102. Think the oil made it faster? (sarcasm) The new wheel/tire combo on the car saved right around 60 or so pounds (if my memory serves me correctly).

Less weight is more HP....period. If you don't know this, you don't know anything about racing/performance (this remark is NOT intended torwards anyone in particular - just a general statement).

Correct me if I'm wrong, but are you implying that a 1 lb. weight loss gained you a .4 second and 5mph gain in the quarter mile?


Seriously, man. That's absurd. Unless that 1 lb loss was all distributed at the outer circumference of your rear wheel (and it's not), which would maximize the loss in your wheel's rotational inertia between the 525 and the 520, there's no way in hell that a .4s quicker quarter-mile is attributable to the weight loss from a 520 conversion. You'd net a bigger straight-line performance gain by skipping breakfast, wearing lighter underwear, and making sure you take a piss before getting on the bike. And your illustation about the mustang doesn't help much. A 60 lb. difference in unsprung rotating mass is a big deal; a 1lb. difference, being ~.25 percent of your bike's mass, is utterly negligible.

How about this. Pay attention and READ THE WHOLE POST DUMBASS. I said, the .4 MAY have been due to me becoming a better drag racer, but what the hell does that have to do with FIVE MILE PER HOUR? Little to nothing. If you don't already know this, then you know very little about drag racing.

Ughh....I'm sick of this shit. Mods - take me off the userlist. I'm done here. All I see is the same crap over and over. People flaming ppl for asking a question, when proof is offered it's not proof (and the person with proof gets flamed), etc etc. This place used to be such a good place for info (and still is somewhat). People used to be more than happy to answer your questions, try to figure out what's wrong with your ride, etc. Now, it's not. FUCK IT! I'M DONE.

something big has been left outof the equasion in this arguement, it's not a big thing with cars at the drag strip, but it is with bikes

a car has for the most part fixed areodynamics (although I remeber a product that used to be on the market several years ago maybe it still is called ET wax, guaranteed to lower your ET by .01 second

a bike has variable areodynamics depending on ho wou sit/tuck in on your bike, it makes a much bigger difference han a few pounds of weight loss

Oh, I read the whole post. It included such gems as "Doing the 520 conversion yielded 5 mph and 4 tenths quicker through the 1/4 mile for me". Also, the assertion that rider improvement could have improved your ET, but the final MPH must have been a result of horsepower (as if somehow ET and MPH weren't related at all), that was entertaining. You may think you know a lot about drag racing, but I think maybe you could use a refresher on physics.

Also, I don't think leaving a board requires mods to remove you - not logging on is usually sufficient to avoid accidentally coming back.



Cheers.

The SVRaceShop is a Driven supplier. We stock SV kits. Nothing like getting a little performance increase when you swap out chain & sprockets. How much it actually is is debatable but it can't hurt to go 520, lighter weight overall, less spinning and lower unsprung weight! Not a bad deal at all.

but they wear out quicker, what's the gain on the street?

Where did you find that info?

Interesting to know, I've never heard of Driven before a couple of days ago. Where have they been hiding?

Its generaly known the 520 sprockets wear out quicker, well, the rear, cause for some reason steel 520 rear sprockets don't exist, they are all aluminum. If you can find a 520 steel, please tell me.

How about Sprocket Specialists' Titan Tough sprocket?
Better but still not like steel. For example, I took off my steel sprockets at 12k, very minor wear on them. My Afam aluminum hard anodized blah blah rear sprocket lasted about 6-7k before NEEDING replacement. Hence the reason I'm going back to steel,.
