Rolling road nerves...
The Fury is all loaded up to go for a rolling road tuning session tomorrow.
The new engine is still an 06 R1 but a bit fettled. Lightned/balanced crank and rods, ported and polished head (slight skim as well) and pretty hot
cam. It came from (originally) Virgin Yamaha BSB team and is built to run to 18000rpm, so should be safe at stock 13750. Trouble is it's stood
in the corner of my workshop for 2 years and was a bit tight when I put it in, so the RR could be a nervous day.
It runs/starts great and goes like poo off a shovel when you boot it but coughs a splutters on light throttle/low revs and stalls when you pull up.
Hopefully we'll get it ironed out. In full race spec' it (allegedly) made over 210bhp on the engine dyno but its a bit downgraded now
(not got the silly-expensive charging system that only works over 6000rpm for instance) but the biggest change is the rev range. The guy I got it from
claimed 190+ from it in current trim. I'll be happy if I get that... or more if possible with the bigger exhaust and PC ignition unit.
If it all goes tits-up I'll just have to pull it out in bits and refit the old one in time for Stoneleigh.

I've just booked to take mine to Dale at Bailey Performance to get the V6 running on Microsquirt. I too am a bit nervous as its not turned a
wheel in anger apart from a slow cruise on the drive!
Good luck!

mines booked in on the 23rd and I've never had a car on the dyno before so I have similar nerves!
Where are you having it done?

18k!!! If it is all good to 13750 then I'd say keep going. Did you see a dyno graph of it revving that far? Would sound epic and give you about
100mph in first or something daft (certainly would if still in the bike!)
Good luck in any case Adi!

That sounds very like an engine that I looked at once.
Good Luck.

Sounds like a nice engine but none of the BSB engines were revving anyway near 18k!! Thats motogp stuff. Whats the history of the enigne.

I did think that sounded a little high. And realistically even if it did how many races would it last? Although I suppose it's a double edged
sword as if you constrain the revs too much then you won't see as much of the additional power it was built to produce.

Just to add i'm not knocking it at all but just be wary

Well it's still running. First power run makes me wince but love to hear it going full chat after that.
A bit disappointed though... there's a huge 1.2bhp missing from what was predicted.
Made just shy of 190bhp at 188.8. Did 1/2 dozen power runs at the end and they all came out consistent, over 188. The old engine made 170. Yamaha
claim 181 standard but inc' 10 from ram air (and it seems a +10 fiddle factor, as 160 seems to be a common bike dyno resut)
Torque was 125Nm. Standard is claimed at 100Nm (inc fiddle factor?) so well happy with that.
I suspect the exhaust and air box are holding it back a bit and it was set to run on normal unleaded (don't want the hassle of searching for
v-power) so there may be a bit there.
Sorry, no video. I couldn't find my camera last night but it turned up today in the car... with a flat battery.
but... It's still running. Just need to book a track day and see if I can break it there.

Yeah, very happy with that torque; Getting toward BUSA territory. Also explains the spinning wheels when I test drove it last week.
The torque starts to peak at 8000 and holds virtually flat from there to 10000 where the power is starting to peak and holds to 13500.
Track day booked to see how it drives on the 21st at Blyton. Just got to refit the floor and a couple of other bits.

Is that at the wheels or calculated at the crank?
