Well I am at 156 hp right now I thought the came out the box with that I have a graves ss cat-elimator exhaust,bmc race filter, -1 counter sprocket, and pc3 usb with a custom map.... The exhaust and custom map gave me around a 10hp increase... I would really love to be up in the 170-180's....

 

Is that uncorrected or corrected hp#'s? Also... is that with the ram air effect? If not then you have to take that into consideration, and not all dyno's are the same just like car dyno's.

 

tired to add my dyno chart in the link but it wasnt working :rant

 

cool i saw one on youtube that dynoed that 180 + but wanted to hear from you guys that have one but if i have to port the head and add cams i will and will the yec do anything also if so ill do that also

 

yes i know that dynos are not the same and that was with out ram air affect dont know if it was corrected

 

and are the 07 r1s close to the gsxr1000 and zx10

 

I'm not really to sure but the consensus is that the new 08 ZX10 is suppose to be putting out some good numbers. From this video I'm posting I'm kinda curious if it's all hype but you will have to judge for yourself. In the video they are testing a new 08 ZX10, but at the end they run it against an 07 R1. The R1 gets a bike length advantage at first, but it looks like to me that the R1 pulls further away from the ZX10 regardless of the bike length that it gets. :fork

GvilleR1 - we going to see you racing points at the track this year? They started last Sat for 1/4 and this Sat for 1/8th. I will be there with my Black Busa - come say HI sometime...

 

180+ rwhp from an 07-08 R1?? I highly doubt it.


I believe an '07-08 will put down mid to upper 150s stock (on a dynojet). with all the goodies and a good tune, figure mid to upper 160s, maybe 170. I really don't think 180+ is achievable without internal engine work.

but in any event, I would never pick a newer R1 ('04+) as a drag bike. They don't have the low/mid range of the other liter bikes. And they eat a lot of clutches. I'm hoping to get one more season out of mine before buying something else for the track. I've just had it with these clutches.

 

Surely to God there is someone out there that makes a good reliable clutch for the 04 + R1's for drag racing. :dunno I personally like the way the R1 has good top end power. Hell.... in the import car world Honda's were notoriously bad for low end torque and mid range but they proved they could run some damn good numbers without alot of bottom end. Alot of all motor Honda civics have already busted tens and nines. I could see maybe the 1/8 mile being a little weak on the 04+ R1's but the big end is where they should shine at in the 1/4 mile. Some spray or boost should solve all the torque problems IMO. That's if the clutch problem can be worked out. What is, or who has the fastest record time for an 04+ R1 in the 1/4 anybody know?? :fork

 

If you can keep the rpms where the motor makes power, and if that rpm range is long enough, then in theory it doesn't matter too much if its a high strung motor, or if it makes the power in lower/mid rpms. I'm not a fan of putting a 10k rpm motor powered by hamsters into a tin can, and calling it a car. But each to his own, it comes down to power:weight ratio, suspension setup, and the ability to keep the motor in the rpm range where it makes power.


But to do that with an '04+ R1, you're talking about 10k rpm launching. You're talking about eating clutch after clutch. Check out the prices of yammaha clutches, they've gone up a ton in the last couple years. I use to be able to get the steels for under $2/each. And now they are $6ish. OUCH. not to mention the fibers that without question need be replaced all the time (even if you manage to keep the steels from warping).


Well, thats my two cents. Dont' get me wrong, I love my R1, and its a great all around bike. And its certainly a little more unique, as there are far fewer R1s at the drag.

 

Yeah can I see what your saying but I have just come from the import sport car drag racing scene where I use to have a 450 to 500hp Eclipse turbo, and the clutches out there were limitless for it. I mean they weren't cheap but there were plenty of companies like Exedy, ACT, Clutchmasters, Centerforce just to name a few, but I guess Superbikes are different.

This is the first bike I've had since my last Yamaha Fazer 700, Nighthawk 700S, and last but not least a GS700ES Suzuki. So you know it's been awhile since I've been in the scene, and so now I'm trying to learn about the newer more high tech bikes. Besides it's a hellava lot cheaper to get into the 10's and 9's with a bike than it is with a car even though I still love my 03 WRX. LOL

Anyway... I'm just having a hard time fathoming that there's no company out there that can, or will make some good strong clutches for the R1. What about www.tobefast.com don't they make any clutches worth a damn?

I thought I saw on there site something about a oil line that you have to drill for to help extend the life of the clutch, and I also believe that there was some type of Barnett carbon fibre type clutch on there, are those clutches any good?

 

tobefast doesn't really make anything. they mostly just sell other people's stuff. but there are a couple places to get steels and fibers from. however, most people will agree the yamaha stuff is just as good, or better in many cases. and typically cheaper too. there just isn't a big need for drag specific parts for these bikes. its not as common of a platform to drag, when compared to suzuki and kawi. a lot more people road race the R1, and the clutch options are suited more towards that type of use.


the oil line is a bunch of hooplah in my humble opinion, but some people seem to like it. your mileage may vary.


any liter bike from the last 5 years is a 9 second bike with few to no mods. certainly a different world compared to cars. welcome to a whole lot of fun :-D

 

Thanks bro!!

 

oil line to me is not hooplah. i went from going thru 100 plates (steels) a year, and this past year, i put in 18 plates. 9 to start year, and in october i changed steels for first time since february. thats tons better than before. and yes prices went up on steels. i dont go thru fibers at all.. just 1 set a year. the steels were problem and now my method saves plates. its not secret. just cool down time and oil line kit, and fan on cover with oil cap off between passes. if u want something to back to back pass.. get different bike, R1 wont do it period.

 

heh. I think we've had this oil line debate before. :-D I ran part of the '06 season with an oil line. I wish it helped, but unfortunately it made absolutely no difference what so ever. But I do agree, hot lapping is out of the question if you expect to get more than a half dozen passes out of the clutch pack. It doesn't help that I'm still short wheel base, and not geared. I probably went through metals at a 2:1 ratio to fibers. I seemed to eat a fair number of fibers compared to you and a few others I talked to.

I'll see this year... I have no oil line, and the billet basket actually has no holes in the side to allow oil in anyways. so my only "clutch mod" being the enlarged oil feed holes in the tranny input shaft.


one of these days I'll have to take some picture of my box-o-plates. Its pretty funny (almost sad) how many clutches I went through in the two seasons.

 

well i know it took a while to get the clutch thing right on my 2000 r1 but stay away from ebc they are junk and killed one motor and it still has a funny sound that i cant find still but im going to try the new 07 -08 r1 is there must diffrence in the 07 - 08 as far as upgrades its for my wife she wants a r1 for drag racing so thats what she wants shell get lol

 

The R1 is a good drag bike, not as big a drag racing aftermarket as the others but can still be done no problem. I love having the underdog bike, its been great so far taking down the gixxers and busas. Ive have had good luck with my cluthes this last year have only gone through one set, and im pulling plenty of 1.50 60s and 6.01/8 times, i guess im lucky up to this point.

 

yea short WB and not geared wont help clutches. its just hard on them and they cant take heat. but try ur best to let them cool, take oil cap off and i put zip tie on clutch lever pulled in after each pass to let them pull apart and get oil that clutch line has fed to them. if pressed together, they wont loose heat, and no oil will soak in.. it will just follow least resistance and drip down. key really, is cool down regardless of oil line/no oil line.

 

Those are some good pointers on cooling the cluth down, ill have to give that a try this year.

 

well i got her an 07 r1 now looking for a side winder exhaust and going to get the chromemolly swing arm made and the correct loering links then off to the drag stripand c what she can do then ill start dyno tunning and c the difference and progress
