Any idea how much your R1 rims weight? What kind of mods you needed to make them fit? Thanks in advance!This is exactly why I switched to Yamaha R1 sportbike wheels so in the future I can just bolt up and go some 17" carbons. Get them and you wont regret it!!! ( your wallet will hate you though)
Thanks! I think that El Pozzinator made a good point, the weight difference definitely makes improvements on ET at the track but probably won't show much at the dyno. In my case I think any wheel I swap will help since I for what I've read the reactors are the heaviest factory wheels for a V.Not sure on the wieght but theyre waaaaayyy lighter than the stockers. It was a good amount of work to fit them but well worth it. Search around you should be able to find the thread. The bike looks much different now though ill try to get some pics up
http://www.golenengineservice.com/html/calculators.htmlThe other questions would be
A) how much improvement or what is the correlation between ET vs. pounds
reduced? (example: after shedding 20 pounds from the bike the ET improves by 'x' seconds, etc).
B) what's the improvement on ET after
a particular wheel swap, etc? :hidesbeh:
Here are several calculators that help project the effects on a race, these results are smoothed or averaged, real race conditions yield different results.
Using the Destroyer as an example minimum racing weight 770 pounds and spec horsepower at 165 yields projected 1/4 mile time of 9.73415 seconds
If all other factors remain consistent except weight which we run at 790 pounds, the run would take approx 9.81771 seconds.
The extra 20 pounds cost 0.08356 seconds huge effects. Which reminds me the diet starts NOW. :soapbox: I need to get myself to about 190 to 200 pounds. :spank:
weight is incredibly important at the drag strip,, prostock bikes don`t run more than about 3lbs over the weight limit because any more would loose too much performance.. i got pretty heavy when drag racing my kawasaki and went on a diet .. 60lbs made about .7 in the 1/4 mile.. went from 9.6`s to 8.9`sThanks a lot! I will take a look at it.
LOL about the diet, there I may be able to help you! I did lost some 60 pounds in about 1 1/2 years, it can take you LOT less time, but I didn't wanted to push myself too far and then dropping out... I'm not a racer but an opera singer and nowadays there is no " 'till the fat lady/man sings" thing, they all want Barbies and Kens on the stage! :bs: (yeah, even if some of them sing like crap, the looks has taken precedence over the voice...) :banghead: fftopic:
All you need is what ALL of us know already, eat less and better AND do some kind of exercise! (WOW, what a discovery!) First thing is starting any kind of exercise progressively, in my case I've always prefered weight lifting over aerobics, which helps BUILD muscle that eats up fat faster (even while you sleep and after quitting doing exercise) instead of LOOSING muscle along with fat with just diet and aerobics. As an aside, as a professional racer you should think also that bigger muscles protects you from (God protects you!) any accident you may have, it's not uncommon to see well built people (in a healthy way) getting less harmed and recovering faster than "normal" people.
Anyways, another thing is food portions. My wife got a gastric bypass 2 years ago and from her post-surgery process I realized you can happily live and survive (LOL!) with only 3 ounces of food and plenty of liquids. Even though that's an extreme, she started eating bigger portions subsequently, so each time we were eating out, we would share the same entree and all of a sudden I started realizing I REALLY didn't needed all the food I was used to eat (believe me, I'm a PIG when it comes to eating!) That's all I did, exercise at a normal, bearable pace and CONTROL what I ate without starving myself. It takes TIME but it happens if you are consistent, so you have tamed your bike to be consistent and now it's your turn, haha! Good luck and sorry for all the :blahblah: :blahblah: :blahblah:!
thant reminds me I've gained like 8 pound in the last 2 months for eating crap when I'm away from home....:lamer:
You got that right, with the new Destroyer class rule running weight of 715#,weight is incredibly important at the drag strip,, prostock bikes don`t run more than about 3lbs over the weight limit because any more would loose too much performance.. i got pretty heavy when drag racing my kawasaki and went on a diet .. 60lbs made about .7 in the 1/4 mile.. went from 9.6`s to 8.9`s
