hmmm, i'd like to have one.

I'm sure it's been under a lot of R&D, i mean, they made car transmissions that take huge amounts of pressure and force......


Now, the fun begins when they design a manual gearbox thats operated with a eletronic relay or relay/hydraulic system to change boost

 

[gotxqss]

What about running a boost controller/ecu setup that just changes boost as per gear your in? They already have that and alot of guys use it for the drag stuff.. Would be nice to have like 10 through 1-2 and then like 25 in 3rd when itll hook up..

i think the MS miata changes boost dependign on gear..IIRC likw 1 and 2 get 4-5psi.... gotta love eletronic wastegates...

But i got a M45 so i get what i get depending on the pulley lol

My Mazdaspeed Protege makes 0psi in 1st gear.

My WRX only does about 6-7 psi in first and second gear, at third is when it pulls 13.7 psi.

I don't really know how I've got my dual stage boost controller set up, but appearantly one full turn of the adjustment knob is good for 1 psi of boost. Which makes sense because I peak out at 5 psi of boost @ 4K RPM and I have the first knob turned three full turns and the second knob turned 2 full turns.

my apexi avc-r is set to a gear dependent boost setting. great product but way over priced.

do you mean 6-7 psi at WOT? because you should do 13.5 psi (max boost) in every gear.

In cab supercharger boost controler comming soon. :wink:
If you look at some pics I have posted you should be able to figure it out.

Centrifical SC tranny...what's the point, buy a freaking turbo.

It's freaking large as hell...buy a roots.

 

[renesisdrms]

i'd like to see it actually happen on cars. like to know what significant advantages it can bring to the force induction side of automotive. will it end s/c place on being motor driven???
whats to be of the outcome?

 

[Braineack]

it's a sh*tty turbo. think about it. it uses a turbo compressor and housing.....but it's belt driven. The disadvantage it had before was the fact that the wheel could only spin as fast as the motor spins. so you have no low-end.

with the "tranny" the wheel can have a better gearing based on the load, so you can build boost and torque faster....but then....why not buy a turbo? the turbo will ALWAYS make more torque than a supercharger. It's easy as hell, and think about the working parts that can fail.

 

[renesisdrms]

yea... i have to agree in simply likin plain turbochargers over this new one.
one thought- anyone here know about porsche's new 2 stage turbo technology? i believe the fins on the compressor side expands at a higher spooling rpm. works like if centrifugal gorce spreads and locks two fins forming a large one or something ike that.

not a engineering breakthru if u ask me. someone was bound to apply that old technology which bears a large similarity to the points and vacuum advance of the old schoolers.

sorry to veer of topic.

 

[Braineack]

They tried that in the Aerodyne turbos....they all failed eventually.

posted pics where? are you controlling the SC bypass with a servo motor, or dumping air? Opening the idle control motor @ full boost will shed 2lbs.

but then....why not buy a turbo? the turbo will ALWAYS make more torque than a supercharger

well, not always.. lets say always above 3000 rpm..

 

[renesisdrms]

so i guess porsche turbos has it down. anyone recalls what its called? specs...like size, a/r trim

I can not tell you the info has not been relesed by the builder. But if you look real hard at the pic you can figure it out. :wink: PS hint; I will be able to change my boost anywere from 0psi to 15 psi.

Ohh, Cool, I've been waiting ages to see that Richard, thanks.

Well then here is a more updated one for you.

 

[giryan]

Thanks.
Now with a belt.

So what does it sound like?
Do you get turbo style BOV noises from it?
