This is why a Seca turbo is so responsive at highway speeds

Not my bike BTW.

 

Sweet curve, little on the high speed side. Hey, there is always Montana!

 

Yeah.. typical turbo curve.
Should see what it's like at 18PSI not just 7psi.
Other reality is it's mainly useless. Hell it's mostly useless inna Turbo Car.
Me old Saab can pull as strongly as a Ferrari from 80 to 150 mph... but unfortunately that has proven not overly usefull in real life.
As direct evidence of this, witness the abundance of Turbo Bikes

 

It's interesting to see that curve... pretty impressive!

What gear was that? I'm assuming top gear... with some good math you can get the torque curve.

Also remember you get the good turbo wack at lower speeds when you're in lower gears

Woot.

Exactly woot. As long as you keep the turbo spooled up, it'll have plenty of power. Yes, if you leave it in 5th and whack it, it's gonna have some lag. Drop it back down to 3rd and whack it, and it's a whole different story.

And I'm definetly gonna have to disagree with turbo cars being "useless". I build 2.4L Nissan turbo motors all day long, they make an easy 400+whp on pump gas, start building boost by 1500rpms, and are at full boost by 3000-3200 rpms. It's all in how the setup is built, if everything is matched up and running correctly, it's impossible to beat a good turbo setup.

 

Wait'll hyperdrive is invented...

Sorry Mate. I claim "bullshit" I've been doing this Turbo thing For 20 long years. Almost NO turbo will biuild full boost by 1500 and frankly the Datsun 2.4 lumps/engines simply are not engineered adequately to produce that level of go.. reliably.unless using one of those worthless Dynajet things to 'measure' output.
Turbo .. even the word, sadly, brings on all manner of unsubstantiated claims. Basic rule of thumb: 1 psi = 5hp. in 22 years I've not seen any evidence to prove that rule significantly wrong... wish it weren't true , as life would be a LOT easier if it was

 

If you could find a way to reduce the exhaust venturie at the spool. It should make better power at the lower end. Been doing this to diesels for years. The triuck is not to reduce it too much as to cause more back pressure than it is worth. Try and not build too much backpressure. It can be done though.
I dont have a turbo bike or I would try it this winter. Worked on my dodge well. 40 more horses and 3 more MPG. for close to nothing.
