Thread: The Other Ride: 2011 Suzuki Hayabusa Turbo. Yeah. Fast.

2011 bought new with 8 miles (2 dealers did the required 4 mile assembly prep and test ride per policy) and put an additional 93 miles on it before going up for the winter for the build.

First phase was:

Custom fabbed "Stage 1" kit by Noisy Toys Racing
Billet Plenum
Stainless valves and new springs
.080 base spacer
.080 cam chain tensioner spacer
APE Cylinder studs
Cometic head gasket
Bosch 044 pump (300lph)
62lb Secondary Injectors
Billet fuel rail
1:1 regulator
All 6AN lines for everything fuel related
GM 3 bar MAP
Woolich Racing LogBox ECU flasher & datalogger
ECU Boost Controller
19/45 gearing
stock wheelbase
tons more im forgetting

Total Invested counting cost of bike: Roughly $19,600 with the bike being $12,200 of that.



Now this lasted all of about 48hrs because of a simple screwup on plumbing the wastegate. Turns out the boost reference was routed incorrectly so instead of forcing the gate open from the bottom it was coming in the TOP to help keep it shut. Whoops. The bike saw 24psi on 3 separate runs resulting in this damage:



that's a pic of pistons 1 & 3. holes on both in identical spots. 3 failed leakdown almost instantly. bike still ran gorgeous when we brought it into the shop for inspection after scanning the ECU and discovering the actual boost encountered. you can imagine what the rods look like. it wasn't pretty.

Phase 2 consists of:

Custom proprietary machine work for high HP reliability and oiling mods
Machined for 1/2" cylinder studs
Main studs
Wossner forged Turbo Pistons
Wossner Forged Rods
New Cometic head gasket to match studs
no base spacer or cam tensioner spacer
Installation and testing of ECU boost control
E85 fueling
dual mapping for low/high boost
All engine controls, boost control and mapping are being done through the stock ECU.

Estimated total invested: $22,500

Estimated whp: The E85 will max the kit out. ~425whp in stage one configuration. motor is built for and capable of 700whp.

Future mods: Larger head unit. Insane amounts of boost. extended swingarm. Coffin.

Yeah, cuz hayabusa's need to be any faster....lol. jk sick bike man!!

It didn't NEED to be any faster...but i wanted it to be faster...

It's actually very streetable up until about the 6 to 8psi mark. after that it just gets flat out retarded on stock wheelbase.

On one of the accidental 24psi runs my local shop owner/tech/mechanic took it out and in 6th gear at 140 he snapped the throttle wide open and he said the bike stood right up on it's ass. I took it out later that night when it got down to about 45 degrees and ran it up through the gears myself and it starts to build boost as low as 5 to 6k and it broke up real bad by about 10k where it was seeing that 24psi. i dunno if i wasn't hooking up cause it never really pulled the tire up for me but it literally feels like you're the coyote strapped to the acme rocket or sitting on the nose of the space shuttle during launch...it's that damn fast...

I can't wait to get back to work in the field so i can get it finished off with a larger head unit. 400 and 600hp on a streetbike are equally worthless on the street so i might as well have the bragging rights too...

Thats crazy fast! Im not trusted on a bike, but id like one. Lol

Holy porkchop!

it's just a shame that it's a busa. ugly bikes.

otherwise i love it.

You see one turbo busa... you seen em all.

But props for the work man!

I've seen a Turbo Haya in action. You freakin' nuts to do something like that...in a good way. LOL

It is relatively overdone...but It's got the most aftermarket and is one of the most capable platforms to start with. Sort of a smart move...unlike a GP

I hope not. I'm located in Bradford, PA and although a fan of Pawn Stars i have no desire to meet those toolboxes in real life.

I was told several times im gonna die and i was flat out crazy for doing this. I'm still around so far. People tend to forget the bike is only as fast as your right wrist is twisty and it goes without saying a bike of this caliber demands the utmost respect when behind the bars.

thanks for all the compliments though. I'll have more build photos up once i sort through them. Hopefully it will be running about April/May this year and there will be video of the dyno session.

Very nice, can't wait to see where this goes. I want a video of it in action at some point.

this. is nuts. HELL YEAH.

It's a nice build but I've never seen a hayabusa and thought to myself "wow that looks good." Just my opinion though, it's yours and you obviously enjoy it.

My friend Eric bought a Busa for his first bike. It had a turbo within the first month. He let me ride it once and asked "What boost setting do you want? Low boost or high boost?" It's a god damn Busa, I don't need any boost to scare the **** out of myself, so the bastard puts it on high boost just to watch me shake when I returned. Fastest ride of my life.

you ain't ****tin no one...haha

Im guessing low was 6psi. that's good for 240whp all day everyday. sometimes more.

with a good boost controller, built motor and the right sized turbo...high boost could be anything. i'm stopping wherever the kit stops for right now but i know it'll make at least 24psi

you have a good friend...haha

He put down 355whp on it.

sounds about right. usually takes a much larger head unit than a "stage 1" kit offers to get much more than that. most are good til right around 400 to 425hp and then it starts taking a lot more effort to squeeze out anymore power...but it's there...

355hp was pretty fun for all of 3 passes. I wasn't shaking but i was pretty amazed the bike could possibly get any faster.
