Turbo Sizes

[shade]

Forget what rev limiter is set to but those runs are maxed out at 11.2k
Tuner was specifically told don't rev the poop out of the bike to get a max number or you'll be punched in the face.
Bike makes max power at about 10k.
On the 410 pull its a mixture of 91 and 100 to get 94-95 octane. Could I have run straight pump gas...eh maybe.... but I'm not taking chances.
Plugs then pulled to check for lean conditions along with using a scope to look at the top of the pistons. All is well.
Leak down was done to make sure the rings were fully set. Came back perfect.

Yes I went with the ARP studs as well. Great reviews on them.
Also 65lb valve springs and stainless valves

Ok, just sounded that way. Super safe moves with the scope and leakdowns. Very smart. I was told "no" about stainless valves. OEM only. Particular these artists are.

While the risk is low with the titanium valves (OEM) - stainless has been used in many boosted busas with good success. OEM valves just havent seemed to really be the norm with turbo builds(from my research), though I havent seen/read about OEM valves failing in a build.

 

[Kevin Jones]

I couldn't and probably wont get the equation but he was babbling about stainless coating coming off and you know how they do. I was willing to spend big bucks on a set $25 a valve and he said something about kibblewhite and on and on. His canvas. It wasn't easy to find a set of OEM valves though. Luckily a guy in Indy stockpiles them.

yea I'm aware plenty have had no issues but I did a lot of research over at Psychobike with high dollar motor builds and I know exactly wat their builds were and how fast they going and they ALL said the same thing get Carrillo and leave the Wossner rods out of ur motor. They all agreed that the pistons were top notch so it wasn't just my experience it was the experience of numerous others who were lookn to make big power and many did and many had failures.

My builder has them in his motor and he has had no issues. I wasn't chancing a $10,000 motor on them again.

and no offense but I was looking to make almost double what ur making in that video so can you really say that u have tested them to the limit? kool video tho. bike looks badass

An alternative view on the wossner rods. Not to point fingers Brett, I have read your story on the rods, but there's so many variables to say the rods suck, that's just a blanket statement.
You cite many others but again you don't know their setup, tune, who built it, etc.
I'm sure Powerhouse built your motor, if so I would say its not a build problem. Powerhouse is good stuff
Carillo's have also been documented to fail.
I am no dealer for any brand I just want to use the best for my application.

My bike has seen light street use and several hard pulls on the dyno at 350 all the way up to 410@ 20lbs. Several at above 400.

Gen2
Wossner rods/pistons
ARP head studs
65lb valve springs/Stainless Valves
RCC Stage 2 with Comp 5558 turbo
RCC intercooler
65lb injectors

Little dyno porn

They've been tested at over 400 plenty. I think they would be fine @ 500 which I may do some day.
Not sure anyone knows the limit of any rod though especially if you are looking to go 700+?? Do I have that right?
Sorry but no rod should be EXPECTED to hold at that high hp levels.
Appreciate the comments.

Had Wossner rods at 700hp no issues, also many customers had them in for 4-5 years of racing & no issues. Cylinder stresses are hugely exacerbated by misfiring problems.

 

[GoldenChild]

I honestly think cylinder detonation at 350 hp is enough to twist a rod well before the rod itself fails, or contact happens and start the downside of the roller coaster. throw gas on a fire at 0 hp and look at the flash back in a open space imagine the pressure of detonation in a small cylinder space. This not for argument,but from being on the dyno and hearing it start to detonate and cutting throttle.. lots of pressure in there something will fail and that is whatever is impacted the most be a piston or rod. most force is on the end item and reverbed back to the next item.. i use all types of stuff in motors and must say wossner has proven itself to me enough that we stock lots of it,.....

Its hard to make a Busa det at 350hp especially on the dyno unless its needing huge boost to make that. I often found its the 'other' things that can cause issues. Weak spark (very common with plug in coil quickshifter connectors or non gapped plugs) or excessively rich A/F that wont burn, iridium plugs, wrong injector currents, weak spark voltages, duff charging system etc etc that sort of stuff. Soon as that cylinder misfires a couple of times it whams the cylinder pressure into orbit. Twisting a rod though ? One of my guys is 23 stone & he puts in 30+psi on a 7" slick & had the same Wossners for 5 years & he whams the rev limiter every other pass. They are still good & go back in with fresh bolts.

Damn big cc thats great news about the rods you have out there in the field. The feed back is great, same thing GoldenChild, thanks.

 

[GNBRETT]

they have worked for many for sure but wen they fail at 350 hp their jus not for me. sure many things cud go wrong no doubt but I had ZERO detonation with a perfect A/F rating so they jus don't give me that warm and fuzzy feeling so I will never use Wossner rods again.

u will probably have no issues with them but wen a rod lets go it tends to cause catostrophic damage! like I said my builder has them in his and he had had no issues and his bike makes about the same hp as mine give or take.

and I agree 100% if ur pushing ur motor to 700 whp then yea I think ur playing with fire and u may get burned and if u do its more acceptable. but not at 350 whp.

They've been tested at over 400 plenty. I think they would be fine @ 500 which I may do some day.
