18 front 40 in the rear most of the time (good for about a true 212mph). 39 from time to time. Which is god for a true 217mph.

Tis the season, let's play nice boy's !

Actually here at Suzuki-Bikes, none of our members ever ride above 60 mph. We are a sensible bunch that obey all trafic laws.

Yeah Right !

Hell if I wanted to, I could make a video of my wife's Corolla going 200mph in our driveway. Speedo's are so easy to tamper with that they can not be used as an accurate mesure of the speed someone is traveling at on a video.

Do you have any idea how much more power a bike needs to go from 180mph to 200 mph?.

I'm very glad that the 200 mph members do take what they're doing seriously and do it under controled situations.

As for mounting a video cam on a tank and blasting around on public roads, well the biggest question shouldn't be how to go faster but rather am I going kill someone.

Thank you Uncle Bob,

Most people including myself try to keep the speed in perspective. As you would see from the record holders they are at Bonniville and Maxon, not on the roads. I do not think any of us that are capable of 200mph go above the posted speed limits on the open roads.

:twisted:

Your point is well taken though for many riders that think it is easy. It can be very fool hardy if you don't know what you are doing.

what size is the turbo? what trim is the wheel? what size is the piping? when does the boost come in? what rpm? how much?

well i'm getting a velocity racing stage 2 turbo from USA, should be here for jan :mrgreen:
oh,ive got a 2002 hayabusa
if i can't find monies for engine work in 2004 then i'll limit turbo to 270 rwbhp
else i'll be going to around 400-430

what size is the turbo how many m/m, and how many boost are you riding

something about that dyno doesn't sit well with me. in order to make that much power, it requires a larger size turbo. larger turbo means turbo lag which would mean that the dyno would be somewhat flat initially then once the turbine gets going, there will be a jump in the power. this dyno is too linear for that effect to happen.

even looking at the Velocity Racing website (http://www.velocityracing.com/) and looking at their stage 2 kit, they state best you can do is...

The standard kit has a 6lb spring in the waste gate. This kit has a starting boost level of 6lbs - 230 hp, then the second stage of boost is safe on pump fuel to 300 hp at 11.5 lbs of boost.
(second stage of boost is adjustable with the included boost controller) Then it's maximum performance (if you choose to use it) is 360 hp at 20 lbs of boost with water injection.

As far as engine modifications; only thing required is to lower the compression by means of base spacer plate (included in kit)

If you want to make as much as 430 hp then we upgrade you to the dual ball bearing turbo that takes you from the 360 hp to the 400 hp

And to achieve the low 200 hp boost levels we offer a 4 lb spring for the Tail wastegate.

so at 430 hp on a GT25 turbo at probably about 25psi, it still doesn't match up with your spects on that dyno. so can you please give details on the specs of what ever turbo it is you are running.

btw, that same GT25 turbo is used on lots of sport compact cars in stage one kits and generally is good up to about 250 maybe 300 whp before it falls outside its effeciency range.

Not so on the bike set up. MotorHead can give his own specs (I am not going to talk for him), but on my baby Turbo Busa with a lot of Mods injectors fuel rails etc. I push 310hp on 14lbs of boost with a small turbo. It is very smooth all the way up. On the dyno I have pushed 331hp with the boost at about 17psi. I keep it around 310hp now. The MotorHead has been doing this for a long long time, including my very first tune (I have done a lot since) on my Hahn Turbo. I am amazed at the figures that he has come up with, he has actually pushed even more hp then what he has shown. You are right about one thing though you can show a smooth line on any Dyno. The Dyno can be set smooth or show every hickup. I like to see the hickups some don't.

IT'S A T66 WITH AN S COMPRESSOR HOUSING CERAMIC DUAL BALL BEARINGS WITH A STAGE 5 TURBINE WHEEL
ITS NOT OUT OF AIR
ACTUALLY IT WAS OUT OF FUEL IN THOSE GRAPHS I WAS MAPPING IT IN
THATS WHY I SHUT IT DOWN EARLY
ONLY HAD 500 CC SECONDARIES IN IT
STUFFED SOME 720S IN IT ANS A RESISTOR PACK SJOULD BE READY TO DYNO
WELL WHENEVER I GET BACK TO MONTANA AND DYNOJETS HEADQUARTERS TO MAP IT

SEE I WAS WORKING AT GETTING THIS RICH DIP OUT (I DID)
AND YOU CAN SEE WHERE IT BEGINS TO RUN OUT OF FUEL
SINCE FUEL FLOWS A GIVEN AMOUNT in a given time frame
THE SHORTER THE TIME(rpm)
the less is flowed out of that size injector even if its at max dutycyle

This is Keith
- A T66 is a big ass turbo. Can you provide pictures of your set up? I'm not doubting the power you could be laying down but there are lots of things being left out. I don't even think (I could be wrong however) that a T66 requires alot more exhaust gas to get spooled up and would even then would have a good amont of turbo lag.
Here's a link to a picture of a T66 installed in a mkiv toyota supra

Keith again,
this is a dyno from a T66 powered mkiv supra. of course this is from a I6 2.6L engine. notice the initial lag then the huge spike that is nonexistant on your dyno.

sheesh the supra is 3.0 liter!
and it is also peaking at 1/2 the rpms :roll:
needless to say they are similar if ya read it propperly
half the size motor trice the ropm for same size turbo
but my turbine side is smaller than his
its an 063
all i do every day 7 days a week is turbo bikes
i know what i got i know what works
just not whats the perfect setup yet :wink:

THEMOTORHEAD

· #38 · Dec 27, 2003

turbine sides too large on that supra for that hp level
still has yet to peak before redline.
poor powercurve only because you are never in it (redline)
pull it down 1 a/r if you are going to stay at that hp level.
nice hp though :wink:
