Local to me so would be rude not to come along really. Will try and make sunday.

Ahh, makes sense. I'll tap a few injectors in the bottom of the air box for low down power gains.
Just need to find some unicorn fuel.
-
Can I add some unicorn power to my horse power or are they not compatible?
I only want unicorn power in first at low rpm but I'm worried it might mix with horse power and become horsicorn power which I believe is nearly useless.
Im not ready to go full unicorn just yet.

@Leblowski I think my cam figures were based on your experience.
It should have plenty of fuel through 4 650cc injectors.
John who's mapping it comes highly recommended and has loads of experience so I can only assume he's damn good at what he does.
Seems a bit cheeky to ask someone else to look it over...

@Arttu they're aome good numbers, I should definitely be getting more then.
Read back on the build threads and checked a few details.
I have a 1.3mm squish band and a static comp ratio of 9.17:1 not the 8.1:1 I said in the OP
Cam timings are
Intake LC 108 degrees ATDC
Exhaust LC 109.5 degrees BTDC
Overlap 16 degrees
Assuming I've measured them correct are they about right?
I'll probably get a mate to check them over just to be sure anyway.

Fried the alternator on my 1100W blow through EFI turbo setup. Discovered that the stock alternator is not up to the task for sustained low rpm's. Adapted a 40 amp alternator from a Triumph . . . charging problems solved
170 bhp/100 ft.lbs . . . I can get that out of 1145 normally aspirated, so something is definitely wrong with your setup.
Thats what I'm thinking, I have one with oversized high comp pistons thats at 145bhp so I was expecting more but its a start I guess and its running sweet so could be a lot worse.
-
Thats the ball park I was expecting to be honest. I think 200 should be achievable.
I'll have to go over a few things once its back.

Update time again!
List of failed parts over the last few weeks are
Alternator
MAP sensor
Boost control bleed valve
Not looking forward to the bill!
It is running and fully mapped now though so close to bringing it back home.
Intake temps are high at 65 degrees but guess thats a draw through setup.
Running around 170bhp with 100ft/lbs torque @ 12 psi boost.
I think there's more to be had but I need to bring the intake temps down a bit.
I'll bring it back and get it on the road, get a few miles on it and finish the water injection and air shifter.
Hopefully some fun miles ahead!

The other 1100w makes 146bhp and thats with 1mm (or 1.5mm?) oversized 12:1 comp pistons, akra and air filter.
That along with the info above makes me think there's something holding it back.
Maybe high intake temps, cam timing or possibly too big a turbo?
I'll get it back and on the road first and see how it goes.

Interested to know what others are running in terms of engine work and components compared to what boost you're running with and draw/blow through.
Power output is maybe irrelevant as the engines will differ but maybe throw it in if you know it.
Intake temps would be good if you know them too.
Reason I'm asking is I finally have some figures back from my build and its on the lower side of what I was expecting, its not bad at all but I think there's room for improvement.
So I'm 1100w
MTC turbo pistons, dished
Corillo rods
Balanced crank, rods and pistons.
Standard sized valves (kpmi)
8.1:1 comp ratio
~170bhp 100ft/lbs torque @ 12psi
Intake temps around 65 degrees
Draw through fuel injected.

Yea it was a good looking stand, well done to all involved.
Hopefully have a bike to put on there soon.
Put a few faces to names too which is always good.
Cheers everyone

Looking good, I'll wonder over later.
There better be Rocky bars...

The RF9 has a pink wire that cuts power in the lower gears. It can be disconnected for more power in 1st.
Its not on any other water boiler though and I'm sure if it was on the oil cooled it would be known on here.
Serious answer over, back to the piss taking!

Haha, yea the Overclockers thread is the complete build so I bet its quite a read.
Got the k2 clocks working fine I think, even got the fuel light to work with the slingy tank sender.
Just didn't like the look too much.

Small update, bike is running well with just some final full throttle mapping to do.
However, the voltage is dropping to 10v whilst running. John has double checked the wiring over and is sure it the alternator.
Its a problem as the fuel pump slows when the voltage drops causing it to go lean.
I've pulled the alternator off the other gsxr and its currently on its way to him.
Just another small annoying problem.

That'll do nicely @Pedda, thanks.
Think the front tank mounts are different on my frame as the coils mount there. Easily sorted I think.
-
Cheers Rene, got a close up of the rear tank mount now and looked at diagrams on Alpha Sports of the headstock.
Could just do with a pic of the headlight frame mounted to the frame if anyones got one.
Cheers
-
Anyone got some pics of a kat frame?
Preferably around the rear tank mount and how the headlight subframe mounts to the frame.
Does it use the same front tank mounts as the ET?
Thanks

The rads are ally.
I'll probably have some spare pipes if you need them though.

There doesn't have to be a logic, thats just the way it is...

At least I'm helping your day Kid! You could always catch up on the old site if you wanted and hour out...
Still making progress Ash, John messaged me the other day, mapping continued without fault, little smoke but nothing bad.
Gone for 12psi boost pressure, think that'll do nicely.

Cheers, looking forward to it finished and some nice weather.
Dropped it back yesterday, its all good. Will be fully mapped and finished with everything mounted correctly etc.
Just hope that breather has sorted the turbo problem and it doesn't come back at higher rpm.

Also forgot to add my 'finished' pics!

Quick update, bike is now home but its not all good news (story of this bike)
Wiring and ecu install is done, mapping is done and highest power run was 180bhp. Quick shifter is fitted and working so no clutch needed above 4k rpm.
Starts on the button from cold, hot, warm etc.
Clutch cover breathers are welded in nicely.
Now the not so good news. Turbos fucked.
Got some serious play in the exhaust wheel, not touched the housing yet but theres a cleaner line in the carbon where it runs so its close!
Could be a reason for a few lost horses and probably won't help the running too much.
Will be having a chat with Owen Developments tomorrow and see about getting it rebuilt to suit the bike.
I don't know what spec it was built for but compressor wheels suited to the bike should make the most of it.
The ecu loom is stand alone so my original loom now has a few redundant wires, will pull that apart and slim it down now as its only doing lights etc.
Stu has a long wait for milling so going to see if I can pull in a favour from a mate and get some clip ons made up quicker.
