    Exactly my thought and besides i know several Single Turbo Supra guys that race these bikes all day long and a Supra with less then 600 RWHP doesn't even stand a chance against these bikes.Please don't take my wrong but any bike over 600 cc be a very tough to beat in your RUF if your car has 450 hp.

    no problem yasir and point is well taken. i said in my post that r-1's gixxer 1k's are too fast...for anything w/ exception to a pro street drag car.

    having said that though, 600's are fair game as are lots of 750's. lots of times if i get the jump and can get into the boost, its over pretty quickly.
    on the other hand if the bike is sitting in a good gear and is waiting at about 10k rpm's...a gixxer 750 will get away but a good race w/ and r-6.

    i know there a re lots of avid two wheelers here (i am one also...too many toys and not enough time!) but my comments were not to flame but to point out how quick these cars have become over the years. it's crazy that w/ engine managment where it is today, there are some porsches that are making as much hp as the kremer k-3's that rocketed down the mulsanne...only now they are running out on the street!

    Did I see you Beverly Hills 90210??

    I think that was you..


    Glad to see another POrsche continued on..They are amazing car...I just love the RUF 930's.....They are just something everyone should have the opportunity to experience. Now if I can just get people to stop calling them "ruff"...It's "roof" as in shingles, dog bark, and "raise the roof"

    Hi Yasir.........

    My brother road races bikes, and he can explain better than I; however, I am somewhat familiar with this topic. This car has never been pulled by any bike yet above 80 mph and up. Now, my bro tells me that there are some new stock bikes that run under 10 second quarter mile times at about 140mph, and that if I come upon one of these, the RUF will lose. The guys that ride these bikes are as surprised as you. Some won't even look at me afterwards, but most are giving thumbs up, or shaking their heads with a grin (one blew me kisses)! The reason, as I understand it, is that my 450 RWHP is much more effective pushing through the wind resistance generated by the higher speeds. Note that (in the one case when we had enough open road to safely stay in the throttle) as speeds increased (up to 150) I increased distance between my car and the pursuing bike. I suspect that even the hottest bikes top out around 185...and these RUFs will keep going (many of them) above 200mph. The CTR will run near 220mph (217, as I recall).

    My brother Steve may wish to weigh in, as he has lots of track experience on (many) bikes. He is much more familiar with them than I. I just know they are fun to play with if we get a safe open road to play on!! I believe that a well-driven 4-wheel high-HP car will turn faster laps at high-speed tracks too.
    Steve???

    BTW....I did used to post to the Rennlist, but these three kids keep me so busy, I can't even get my racing rubber mounted on the racing rims I bought a LONG time ago!! They have slowed me down significantly...but they are worth it!!

    Sheila,
    Lets say your car weighs in at 2800 lbs,although i think it's more like 3000 lbs,any way with 450 rwhp the power to weight ratio is 6.2.The supras on the other hand weighs on an average of 3450 lbs and with 700 rwhp the power to weight is close to 4.9,so on paper a Single turbo Supra seems much stronger & yet they find these bikes hand full.
    However it's quite possible that the bikes you are running are much smaller ( under 600 cc ) vs 1000 cc that the Supra guys are running,i don't know ? please don't take me wrong i am not here to brag about the Supras and the only reason i mentioned them is 'coz i am quite familiar with them.
    Btw your car is very nice how about posting some specs and the factory mod list ?

    Trust me........I have roadraced bikes for about 10 years and know how to ride. Sheila's RUF will take my late model R6 from about 50 mph. It is about even until over 70 when she starts to pull away. Most bikes (especially 600's) are quick but not fast. My NSX will take a modern 600 from speeds higher than 110mph. Obviously the new 1000's are quick and fast, and the outcome would be different. The R6 only runs 128 through the 1/4 mile, with a 0-60 in 3.0 seconds, it is obvious the bike is beating a fast car the first 60 mph. My 600 is relatively gutless at 130 mph and only tops out at about 160 so you figure out what is going on here. It takes lots of HP to overcome the wind at high speeds and the small output of 100RWHP on the little 600 can't hang at these higher speeds. You are her typical victom as you under estimate the stupid person in the bright red P-car and fail to respect it. Next thing you know she is gone and you realize it is too late to go for the next lower gear as you would never catch her at this point. I am telling you the car is bike fast........trust me!!

    New R6 puts out about 103RWHP and weighs 365ish dry. Now throw in you average 175 lb rider with his helmet and clothes and oil and fuel and you have a hp/wt ratio of 5.67 lbs/ hp. This is not much better than the hp/wt ratio of her p-car. The difference is the hp it takes at 100 plus mph, the car keeps on pulling and the bike runs out of steam. I have personally raced a new F4 in her car and gave the guy the benefit of the doubt at about 70 mph and let him have the jump. He was in the right gear and in a full tuck and her Ruf pulled 2 full car lenths on him by 100 mph.
    As far as track times go, I am sure that I can run better times than her car on the tighter tracks that I have to compare, as I have seen the fast cars times at Hallett and am running about 5 seconds a lap faster. Road America would probably be a different story on the little 600. Average driver in the Ruf to average rider on the bike, the car wins. The skill it takes to ride the bike to its' potential and the consequences of a mistake, make it hard for an average rider to stay with a fast car. Also, you mentioned Supras to weigh 3400 lbs, (I believe them to weigh more than that) 3400lbs + 175 lbs for driver and even with the 700 (805 crank) RWHP you are claiming, you are looking at 5.12lbs/hp at 3400lbs vs R6 at 365 dry, add fluids with 175 lb rider and 10 lbs for riding gear and you have 5.67 lbs/hp. Again, this will be close out of the hole, but the car will start to pull as wind begins to play a role. I have informed her not to play with new GSXR1000's and ZX-10 etc as they are stupid fast. On the other hand, these are the guys that underestimate her car and don't bother to downshift as many gears as they should, and by the time they realize how fast the car is (or was) they need a ways to recover the momentum . A well driven high hp race car with AERO will absolutely destroy ANY (including MOTO GP) motorcycle on the track.
    I am sure this has been discussed many times and don't get me wrong, (I LOVE BIKES) I am not slamming the 2-wheelers but rather trying to put into perspective how fast these cars really are. I did not understand until I rode in the RUF the first time. I got out and told my race mate......."man, that thing is BIKE FAST!!"

    Some years ago, Car&Driver had the standard car vs. bike test. FZR1000 vs. Viper GTS IIRC.

    They discovered that the car did actually accelerate faster up top than the bike, just as you guys have seen. The bike's pwr/weight ratio was better but its pwr/drag ratio was worse.

    Nice Porsche, BTW. My brother-in-law has a 400rwhp '88 911 Turbo. What a beast.

    Wow, its very interesting to see this thread. u may wonder why...well... currently, my mechanic, Mike Holman, was Steve Beddors mechanic when Steve and the family picked up their 4 Ruf's... yes, 4 of them..one for each family member...along with all the extra parts from Ruf. they were shipped to Pikes Peak run (i think) via Fedex...talk about having a lot of money! the Beddor family, being the lead printer press holders in the state of MN, are wealthy group and well deserving!

    secondly, i had the pleasure of riding along in one of those beast, the yellow one of the brother to Steve (Dave i think) while at exotics day up at our local track here in MN, Brainerd International Raceway. man, that car was absolutley sick...i was scared how fast that thing was!!! just jaw dropping power and performance. though, the multiple wipe outs on the course made me uneasy.... lol...

    lastly, all this talk about bikes beating these cars...well, heres my opinion. i have 4 bikes. a harley for cruising. a 93 CBR F2 which i bought junked, and rebuilt to work perfectly. this was more of a project bike so i can learn how a motorcycle works. and old 81' yamaha to learn on, and lastly, an 01' Gixxer 750. farily well modded. it does 131 rwhp, yet still not completely tuned. i can keep up with Liter bikes all day long. so after driving all of different types of bikes, i'll say that the 600/750/1000 are all quick, uptill about 100 mph.. after that, it really depends on what motor u have. my 750 will pull hard still at 150, i can't imagine what a 1000 would do.. so if ur shiela, if ur porsche is beating bikes left and right, they must be older, if not, early 2000 model 600's? correct? i could imagine u beating them especially in the higher mph range. the 750 and up, i don't think u have a chance. most poeple who buy bikes, don't leave them stock...the mod bug will always hit ya! LOL...u know this right... LOL

    soo..yea, just my thoughts...

    heres a pic of mine...

    Frank Beddor was instrumental in the Virginia City Hill Climb. He also prints like 40% of the country's junk mail...deserving...I dunno about that one.

    Sheila, Saw your car with OK plates at the Ruf opening. Beautiful. I loved the cab. Do you know what HP the "stock" Ruf slant-nose's made at the wheels?

    Keep the faith. I love the slant nose cars, but my wife thinks they are ugly. (sigh)

    I believe the Stock BTR was rated at 380 hp. I do not know how they rated the car except for the fact it was rated with the boost adjustment turned all the way down. I think Ruf tends to under rate the HP #'s on most of their cars. I am sure the 380 hp rating would have been produced at the wheels with the boost turned down to about 15 PSI. The CTR was rated at 490 and ran over 215mph. These numbers do not add up! Must be some ponies they forgot to include unless they are RWHP #'s from the factory with the boost controllers turned to Minimum.
