USPS Arrived!!

Well USPS arrived with a huge box of goodies for the bike, i’ll start listing them out as i go through all the pictures.

We start with the turbo itself, It’s an externally wastegated turbo designed by precision, made by garrett. Not that ratings on turbo’s mean to much but it’s capable of flowing enough for 630hp. We will be cranking it up to around 35PSI of boost in race trim.

To help us achieve this amount of boost we need to lower the compression, this is done by a set of Forged JE turbo pistons and an .080″ base gasket.

We are running cometic gaskets throughout as they are proven to hold together in this motor at high horsepower, two head gaskets just in case we pop the first while tuning.

Obviously the stock rods are not up to the task so i snatched a set of carrillo’s finest H-Beam rods and bolts

For the top end we needed some stronger valve springs as the stockers are only rated at about 35lbs, if you do the maths, stock springs + 35psi of boost means the valves would be constantly open, well for a split second until the piston pushes them shut… Titanium retainers help hold the valve springs in place while adjustable cam gears and a manual cam chain tensioner keep the valve timing spot on. All of this gear comes from APE

Getting down to the bottom of the motor we will be running genuine suzuki bearings with the bottom end all held together with after market APE studs, both crank and cylinder head wont be going anywhere.

Now everyone seems to love this piece, Busa’s have an issue with snapping the output shaft above a certain level of horsepower so the motor gets a Robinson Billet Output shaft.

Getting all this power through a stock clutch would be a joke so i grabbed an MTC multistage lockup clutch, Basically you tune in slip up until a certain speed and then the arms start to apply pressure to the clutch plates to lock it up, It’s tunable in three places which should be a good learning exercise. It comes with a new cover so you can fit it all in, a billet inner basket and pressure plate machined with contact points for when the arms start to clamp down.

Yes that’s a big front sprocket, 20 tooth to be exact. gearing the bike for 400+ km/h and factoring in slip is hard but this sprocket helps us get there.
