Interesting Turbo Possibility??
So today I was told Honda might have a turbo for the turbo so that it would spool up faster at low RPM's and then of course the larger turbo would take care of the big speed numbers.
How bogus does this sound to you guys??

Sounds like a common twin turbo set up. very possible!!!

Yea, very possible. That is called a sequential setup. A lot of people though, ie supra owners, mod away from the sequential setup when using stock turbo stuff to produce bigger numbers.

If I'm not mistaken isn't the new 6.4 diesel in the Fords setup like this?
It isn't a uncommon setup though...But as Chris said...usually once people really start modding for more power it's one of the first things to go (as it's hard to tune for)...It would be like having to tune for 2 entirely independant fuel curves and then having to also tune a nice transition (3 custom intertwined tunes vs one for everything)...

Sounds like exactly the reason Honda would do it too. Make a nice solid craft that performs "okay" but is a bear to mod.

i just toss the whole turbo in the trash and install one that's about 3X larger..
that's why a Nitro Stg1 kit is required first to control it.

Hmnnnn. I guess I'm just way behind on this turbo stuff.
nitro, wouldn't running a HUGE turbo still leave the public with turbo lag?
Leading complaint with the Honda that I'm aware of.
So small turbo to get things going fast and then large turbo for higher RPM's?
But isn't turbo lag due to the wait time for the exhaust gasses to turn the turbine in the turbo? If so how does a smaller turbo help with that issue?
Still "turbo" lost.

not enough balls in a 1.2L to warrant twin sequentials.
a variable vane turbo would be nice tho, from the factory.
Going aftermarket would mean just going with the nitro kit..it's safe and all the hard work (tuning) is done by a guy with 30yrs turbo bike racing /tuning/engine building experience.

A large single with a 2 step system of sorts could work maybe. Have a button to push and hold while you got WOT. The ski wouldn't move, just spool the turbo, then when you let go of the button you take off while in boost.

or just use the standard ALS (anti-lag)that is part of the Stg1 system.
