does it really have to open to the big turbo, or is it always open at once there's enough flow then if just starts moving the compressor?


btw, wouldn't a Boxter/flat 4 be like an V4...just at 180degrees?

im still waiting for someone to answer my Q tongue.gif

and Boxter/Flat/Horizontally Opposed should all be same
Boxter is to Subi when getting tech. is Horiz. Opp.
Flat...hmm, i just caused a brain tumor, come back, something isn't clicking
Boxters are also what Porche calls theirs, i think the dif names are like technical name differences from car junkied names, and then the Engineer name tongue.gif

a while back and i found a page about twin turbo kits for the 3sgte on MR2 turbo.... the kits i think was running about 2-3k or even more. The kits estimates hp about 320 stocks. The kits was installed in a MR2twin turbo mr2

If I right, a Boxster is like a I4, just on its side.

Boxster is like flat or H engine.

Small turbo on a stock 2JZ-GTE is a CT20 (not related to what everyone calls a CT20b), not a CT26. The MKIII Supras used one turbo and that was a CT26. Just makin sure to get that bit in there.

if Boxsters are what subaru uses, def not inline four.
they sound sick compared to anything else, a shame their supposed to be hard to work on because they just sound so amazing.

either way, does the larger turbo in a twin turbo really need to "open" up, or does is it always running, just does spool till later

boxster engine, flat engines are defintly not a inline 4

this is a boxster engine

user posted image

those little cylenders are the pistons and the square thing in the middle is the crankcase.


i believe a H engine is just like this only 4 cylenders

Look what happens when you get a bunch of people trying to answer questions they themselves know little about... rolleyes.gif

First off... no... no matter how bad you want it... you cannot twin turbo a 7AFE or 5SFE. These engines are simply too small and don't push enough exhaust gases to spin 2 turbos. The only way it MIGHT work, if you're spinning two LITTLE ASS turbos, or if you're spinning one at a time, in turn, sequential, however, that's not a simple thing either. The sequential twin turbos are designed to preserve low-end torque with a small fast spooling turbo and then a high-end kicker. It'll be COMPLETELY pointless on a small engine because there is no point in spinning the later turbo just because typical small turbos used in these set-ups are more than efficient enough to boost a 7AFE or 5SFE and make good top-end. Supra twins won't work. It's not a matter of having two exhaust manifolds either... or being flat (horizontally opposed), V, W, or inline. It's a matter of physics...

Look at it this way... if people are afraid of boost lag from running a single big turbo... what the hell makes you think it's gonna make it better to run TWO turbos?

ok...even though no1 tried to answer my question, i think Kwanza did smile.gif
there are twin-turbos out there that just work normal...like, ...well i dont want to get into it

then there's sequential which has some kind of valve to open the larger turbo after a certain RPM.
crazy shiat. if it weren't for the smaller one having to keep spinning(right?) i'd say that is the best set-up ever, make a 10K revver...4-7mid-turbo 7-10 INSANE Water Mover

Here read this on a turbo forum:

QUOTE

actually, twins dont reduce turbo lag. also there are 2 types of twin turbos, REAL twin turbos, and SEQUENTIAL twin turbos.

the "real" twin turbos, aka full-time twin turbos, is that both turbos are spooled up at the same time. the advantage of this is that both turbos will be giving u power all the time. the disadvantage is that if u know that turbos work on exhaust gases, well, instead of having the pressure of all the exhaust gases powering just one turbo, u have to use half and half, so spool time aint that great.

sequential twin turbos work differently. mostly, its one small turbo and one bigger turbo working. the key difference is that the smaller turbo will be the one doing all the work at a certain RPM level, and then the bigger one kicks in. ill sure the MK4 Supra as an example. all the way up until 3,000RPM, the small turbo will be the only one giving the car power, and then once 3,000rpms has been reached, the big turbo will kick in cuz the exhaust gas pressure is strong enough to spool it up fast, so in other words, the small turbo spools up the bigger turbo. the disadvantage is that, well, u dont have both turbos working full time, so one of them is just dead weight when they are not operational.


this is where single turbo set ups come in. while a single turbo will have the initial turbo lag of a full-time twin turbo (though the smaller the turbo is, the less lag it will have, get a really small one and u will barely notice the lag). turbos are efficient as long as they can work correctly with the torque band of the car. this means, that it can keep giving nice boost all the way up to the peak torque of the car. remember, torque is turning force (by definition). a single turbo will always be operational, and if u have the money, u can even get a lightweight one to save even more on weight. one bigger decent turbo can outlast 2 smaller ones due to the rotational speeds of the turbine blades (the bigger they are, the less rpms they have to go about in order to create the same amount of power).

full-time twin turbo cars are just the answer to big single turbos, but they are of no advantage just cuz they pretty much require the same force to spool up as just one big turbo, but they have more weight on them so no big deal (double the equipment is needed to run double the crap). then as for sequentials, well, just read the dead weight part above. single turbos dont have any dead weight since they are always in use.

No.

Ok, fine

TTs work any way your mind can imagine them- no I'm serious. There's a TT setup for almost any config. You can have the smaller turbo be the only one working at low RPMs, and then switch off to a seperate, larger turbo for the higher RPMs.

You can have the smaller turbo spool up the larger turbo.

You can have a supercharger that spins freely (does not suck out hp) when the larger turbo kicks in.

You can have two seperate manifolds; one always spinnign the smaller turbo (and always sucking up air) and one always spinning the larger turbo (which doesn't suck up air til higher rpms)


Use your imagination! AND LET THIS TOPIC DIEEE

ok, i'll let it die now...knowing that there CAN be a valve of some-sort to shut down one turbo while another takes over, rather than HAVING to have both run
