very true
300 can be done with mainly stock internals with ease
but railing yes but not at the wheelbase i was at lol
but yes on stock wheelbase yes it can be done
The clutch won't hold!

O.k. I talked to someone who I know builds 300+ hp bikes for a living, he thinks that none of you guys with a stock back tourque limiter have ever dumped the clutch at 7-8k on a vht covered dragstrip. Another mechanic that I know said 3 outings at the strip with the stock clutch will end up totaling the cost of 2 lock ups in repairs. Both of these guys build bikes that run 7 sec. 190mph 1/4 mile times so, they might have had a few trial and error runs with the stock clutches.
I'm considering a 2 stage lock up. The welded clutch has worked fine since 2006, I just have too many miles and passes in the plates.
Brendanp if anyone can ride dragrace a bike,prove it to a girl that I know with a stock motor gixxer 1k. Im not calling you an idiot, but there is a reason that Chip Ellis, Todd and Ryan Schnitz, the Gadsons, Mike Slowe, and Jeremy Teasley are in the mags and ride sponsored bikes. dragracing and roadracing are two different forms of racing.Real riding is whatever type of riding that satsfies your taste. Both require a development in skill to consistantly win. "Real riders" respect the many disciplines of riding, Lee shierts is a fine examlpe of that. His road racing background and engine building skills did not "give" his 7.9 sec 1k the win light in a 1k grudge race. I have been riding motorcycles over half of my 32 years of life and that includes twisties, stunting, and jumping dirt bikes.

welp listen to whoever you please. I stated the facts I have encountered. I have dumped a few clutches in my time and I have also owned bikes that put out more than 300 hp.
You aren't running 7 seconds on a 277 rwhp busa regardless of your setup.
And as said, if drag racing is your main objective...definitely spend the cash and go with something like a lock up.

Way to much HP to RAIL in the twisties my friend! Ride in the twisties "Yes", rail in the twisties "Not a chance", you'll end up dead! 300 Hp with a Lockup clutch is a sure recipe for disaster.
As Brendan said, great fun for straight up riding but you get her laid over on her lips and tweak the throttle, 300 HP will put you in the bushes!

I've put knee down on 300+ hp bikes...When their power is linear it isn't too bad. Not a ton different than a big bore.
I have a turbo gixxer....I'll rail with anyone local once the roads clear up. Let me know.

All depends on how you ride and what you are doing with the bike, by taking the above mentioned racers advice I would assume you want to turn your bike into a prostreet bike?
If not the stock clutch setup will last longer on the street as the more load you put on the engine the more the inner hub pulls on the clutch springs increasing the pressure on your clutch plates. You can get away with the welded hub as well, but I would recommend the APE HD clutch springs as they will hold upwards of 400hp. If you are running at the drag strip a fair bit a lockup clutch with a welded hub is what you will want to use.
Biggest decision with this sort of thing is deciding what type of riding you want to build the bike for, as anyone in the industry knows, its extremely difficult to use a bike for multiple purposes,

well as richard said it truely depends on your goal for the bike
yes the welded will hold for a short time but not real long and trashing clutches is hard on a motor but when you junk a crank youll see (because you didnt get all the fibers out and some clogged the pickup)
there is more around here who have built 300+ hp motors
and to be honest that can be done on stock internal
i am in the process of buildint a prostreet bike (which will be capable of 550-600 hp)
it truely depends on what your goal for the bike is but youll have to try and stick to one or the other as both isnt as easy as they say it is
My bike is not a prostreet bike, but I do like to grudge race and you better bring to run with a grudge bike. It makes more than 300 hp now and when I race it I run it hard. Those guys that I mentioned did all of the work on my bike, I just want to keep their names out of this. What is it that makes the popping noise in the stock clutch? Why does the stock clutch not prodoce the same 60ft times as the modified clutch?

the stock clutch has a ratchet system that when you release the clutch it will ratchet tighter and this will cause the snap (no the stock wont 60 as well as a welded but it will hold the higher power, but at the same time it will break parts when it snaps together this i know ive tried it but then again your limited to power and how long the clutches last)
but IMHO i recommend a lockup and what wheelbase are you?
I've been 1.44 on a stock shock 66" with a 2 stage lockup

I think your definition of railing and mine are two entirely seperate things. Bring your high HP bikes out to the road track and you'll get your buns spanked like a little school girl.
You can coast through the corners and put your knee down. It's brakes and throttle that make you quick. You can take this to the bank my friend, if you try to go fast on a big HP bike it will quickly put the fear of God in you or it will spit you off like a rag doll.
But, if you are sincere, bring your big HP bike and your wallet to the road track!

I guess in your logic then people can't rail on a busa or a 1000 then either

I have no idea where you came up with that? You said you could rail with 300+ HP and was willing to rail against anybody. I was simply pointing out that your experience level at "Railing" is somewhat limited or you are suffering with a serious hangover this morning and your mind is still a little foggy?
Either way, you are no serious competition to anybody while sporting 300+ ponies, gixxer or busa, makes no difference.

So you come to the board, ask a question, ask it again to some "people that did the work to your bike". 7 second bikes arent nameless, so either your BULL**** or your BULL****. With all your years of riding expirience i would think you might have a little knowledge about whats what. Asking what makes noise on a clutch?? Keep your showboat on the grudge scene or go home and learn something.

The seven second are not nameless a well known prostar racer has won 2 events on my mechanics turbo zx14.So, the welded clutch won't hold the power and the stock clutch will hold it, but, destroys more stuff when it does let go. Sounds like the lockup is the best thing for my bike. Who makes a lockup that doesn't require $1000 in other billet parts to make it work.
Get in touch with the site sponsors here. They can easily be found here on the forum. They will most likely make you a good deal and point you in the right direction. GPW, Goldenchild, ect. 2wicked isn't a sponsor, but he knows a little bit about turbos and clutches....maybe....just a tad! All of them can get you in touch with a good clutch. There are others, I just haven't looked.

mre, mtc, rpm
these are a few to start off with
all have a 2 stage system that wont take 1000's of dollars to make work
they are simple to setup
they are also very affordable (the cover would be the part youd need to decide on either get a quick access that cost money or get a cover spacer or your stock one modified (the cheapest would be the spacer or the stock one modified))
but i hate to tell you that wouldnt compete with the other style clutches that are out there for grudge
slider, gann, hays, gen II mtc are a step above when it comes to lockups
good luck with the setup and i hope you find the application that best fits your needs
