Project; Turbo GSXR Slingshot

So John at Track Electronics has spec'd an ecu and given me a price for supplying, fitting and dyno tuning.

I've cried, looked at my bank balance and cried some more!

Things should be moving forward though and hopefully John will work his magic and I'll be picking up a running bike soon.
 
This needs an update!

Ecu is fitted, its been to Specialist Conponents (ecu maker) where they've made a new trigger wheel to suit the ecu and configured the sensors, crank etc.

John has got it running nicely, to a point...

Last week during mapping it started leaking oil from the hose feeding the turbo at 3-4k rpm so that was sorted and mapping continued this week.

Next hold up is that oil is leaking out the exhaust. Not just blue smokey oil, it's literally dripping out the exhaust. Its doing this from tickover.

As it stands its mapped up to 5k and its running real nice, idles smooth with good throttle response, picks up good etc. Just spews oil out.

So its back to wsr where they'll check it over, pull the turbo out, send it off for a rebuild or whatever is needed. Id guess cleaning the turbo out and trying it with the drain disconnected will be a good start but I'm a good 3 hour drive away so I'll leave it to Stu and the boys at wsr.

Did get a quick vid from John with the oiling issue.
Sounds good!

 
Picked the bike up last weekend, was shocked at the mess of wires hanging everywhere considering I'd paid the bill for installing the ecu etc. The other big problem was the breather hose connected to the wastegate, nobody seems to know when it got connected but it sure wasn't connected when I dropped it off.

So I disconnected the breather from the wastegate and*cleaned the turbo and exhaust out. No oil in the up pipe at all so its definitely coming from the turbo.

Ran it up and its still a bit lumpy at low rpm but it runs. Oil spewed out the exhaust again.

Checked the restrictor and its .75mm so thats fine, had a feeling I took it out to 1mm but obviously didn't.

Took the filler cap off and put a bit of hose in it, cleaned the exhaust again and ran it, a lot less smoke and no oil out the turbo.

I'd already bought the bits to get a dash 10 breather on the clutch cover so I've got that fitted.

Runs much better and no oil or smoke


Couple of 'finished' pics that should keep the insurance company happy



 
Its update time again.

Its home now but its had some problems.

List of failed parts over the last few weeks/months are

Alternator - kept dropping voltage and slowing the fuel pump causing the bike to run lean.

MAP sensor - over reading the boost level and pulling ignition timing. Power topped out at about 110bhp

Boost control bleed valve - stuck open so it never allowed the boost level above 6psi.

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.


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 dead.

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.


Should get a few more updates as its back now and progress should speed up a bit.
 
Seriously hope you get this up and running sweet as a nut. With all the time and effort you have put into it, you deserve it. Cant wait to see what it will do on the drag strip :D That long swing arm will come in handy!

Seen one at the Raven Cafe meet the other week running nitrous oxide, without the turbo......Yano.....Just for that extra needed power :D ;)

180bhp? A bit low for a turbo'd engine? What sort of power are you looking at achieving in this project?

Its running on standard engine block pretty much. 180BHP with 100ft/lbs torque @ 12 psi boost is insane. Some cars don't run that.

Your bike for comparison at best:

100ft/lbs when turbo is on boost is hard to control then it hits the 180BHP at redline........

Danm54. You need to mount the intake towards the front of the bike. Right hand side low faring (should bring down intake temp) is what I have seen so far from other people, sadly it looks like you have already made the pipework with the TIG welder. :(

The point I'm trying to make is, you can get a more powerful bike that has no turbo, what's the point of spending money on turbo when you can spend that money and get something faster? There was a GSX-R 1000 with Turbo that had 330bhp and was capable of 450bhp. :D

BTW I'm limited to 47bhp for the next 2 years... :p

Edit Unless this project costed barley any money, than it makes sense if someone loves to do projects like this. ;)

If this gets set up correctly it should make mincemeat of most modern bikes. As you have seen the H2 may look good but its a waste of time. Mass production is no replacement for a specific designed machine.

Not saying it won't. :p

Unfortunately, I would still take it easy even if the laws were different though. Unrestricted SV feels plenty fast for me, no doubt when I gain more experience it'll probably feel like a moped. :p

It was a relief when it ran thats for sure!
Still a long way off running right but thats a job for someone who knows more than me and has the experience of tuning these things.

Got a Buell front end and rear wheel going in. Thats really all thats holding me up now.

Engine wise, everyting has been spec'd for 300bhp or more. Not going to get that much power but the headroom is there and it should hopefully be reliable.
I'll be happy with over 200bhp but 250+ would be nice.

Main thing is it has to be ridable and useable power.

I think it should be making more power than it is but its a good base line to start with. The turbo failing won't have helped matters and if its rebuilt to better suit the engine that might also help.

High intake temps are a side effect of the draw through style setup, but it looks neater and thats important.

The big number mentioned above are common for turbo bikes but you don't know what boost they're running or the reliability/longevity of the engines. Great for the strip but maybe not ideal on the road. Its easy to want the same power as drag bikes but it always comes at a cost and its not really usable.

The guy thats done the mapping also done Guy Martins Pike Peak bike, I think he knows his stuff.

It'll get there.

Are you sure? Guy spent a lot of time swearing at it because it wouldn't run properly :p

I'm joking of course that was never going to be an easy setup getting it to run right in those conditions.

Looking forward to seeing the final numbers.
