Nice numbers man looks like 248hp

Couldn't read it but they say in the video 251
First thing very nice
Second what gearing do you have if its stock you need to go up one on the front or down 3-4 on the rear
Put some race fuel in it and up the boost and hit 300 on that thing that would be even more insane.
I can do 300hp if I would like to, I can boost up to 1,3bar (on pump gas). But i dont want to.
On the dyno print out, it says 210kpa. When you say you can go to 1.3bar for 300hp, does that mean that the 2bar on the print out is really only 1bar minus atmospheric pressure? (1bar for atmospheric pressure + 1.1bar boost pressure above atmospheric = 210kpa?)
So your 1.3bar would be about 230kpa on the dyno? Have i read all that correct? I know that atmospheric is 1bar=100kpa=14.7psi but i'm just confused, but I don't want to second guess you, i'm just confused - but excited for your success at the same time!
Correct.
100kps is atm
I had a pressure of 210kpa (110kpa boost)
And if you do the theoretical calc, 1 bar of overboost means the double of horsepower.
137hp original + 1,1 bar is 287hp.
137hp ........ + 1,3 bar is 315hp
1,1bar is 16psi (bad unit)
But last week my frame broke on the right side. And I have seen that many had it. The weld is completly opened so I have some work to do.
Thanks Alex. Sorry to hear about your frame.
Have you spoke to a Yamaha dealer about it yet. There have been a few people in the USA that have had the frames fixed or replaced free of charge by Yamaha. It might be worth a phone call to find out.
Anyone else like to fill Alex in on the frame cracking history?
You may still get it repaired (welded) with Yamaha paying for it.
Have a read thru some of these for some history/others experiences if you like:

Mate that is just an outstanding job on the turbo, great engineering. The frame is just crap, why Yamaha was not FORCED to have product safety recall on 06 and early 07 bikes is beyond me. They have known about it since 06 and it is a dramatic terminal failure. Yamaha have recalled a lot of bikes for less serious problems, perhaps we should contact the authorities in our respective countries and see if they are aware of Yamaha's failure to recall these bikes ?

Its a known issue you will probably get a replacement. I would remove the turbo stuff first.
I think it was Ballmead who had the same crack. I don't recall if Yamaha replaced it or not. You may want to drop him a PM.

I have imported the bike from Germany to Sweden so im not sure that they will replace me with a new one.
But I have an idea how to make it stronger in that joining so I thinking of welding and pouder paint the frame.
Hi Mr Helmut, Im not surprised your frame broke on the weld. Thats one of the FZ1 weak points. It was probably on the cards runing 286hp. Good luck with your reweld and put some doubling plates on the inside to beef up that area up so it can handle that nice hp you have. They wont give a new frame after a turbo was fitted, better to just get on with it and fix it yourself.:frown:
