Anyone see the issue of Modified magazine with the dual FI tc? It had a TRD SC and a custom turbo kit..... I think they were running a Garret turbo. The article said that it was only pushing like 220whp and 191wtq. Doesnt that sound like the biggest waste of money and time. Ive been searching all over and I cant find any other info on it. Anyone ever hear about this?

i've heard about twin charging being done on tC's b4. its pretty pointless. the s/c MIGHT be able to add SUM power b4 the turbo is spooled but as soon as it IS spooled the s/c becomes drag. its not the best plan. just looks cool. non of the twincharged setups i've heard of or seen on the tC are making much power. but then alot of them are on "show" ****** so they are prolly tuned mad rich sol that nothin blows and the cars themselves will probably NEVER see the track. waste of money IMO. how bout you spend that money to buy me a tank of gas or 3 instead...ya know?

its called Gojira... it has the s/c and turbo
really nice paintjob though.

Old news -- He has been trying to sell it on this site for quite awhile now.

VERY old news... as far as I know it never ran right... is technically sequentially charged, not twin charged.. but people nowaday use the terms wrong everywhere... so sematics dont mean much it seems And as mentioned, mostly pointless with the type of SC that is being used.

it looks nice tho i was parked right next to it at scion vip

the reason the #s were so low is b/c it had a stock clutch when on teh dyno and they were scared to blow it. and i believe it put down a bit more than 220whp a little less than 245whp is more like what it was.

but all in all its a pointless upgrade and waste of $$ u can spend less on just a turbo and make way more power and save money, and the tuning on a s/c turbo tc is rediculously challenging.

the s/c turbo tc is a show car.

It wasnt just the clutch. The point of a sequentially charged car is to use a larger turbo with more lag, but more boost, and a more linear SC (like a roots blower) that will fill in the gap on the low end so you have the best of both worlds.

The setup mentioned here takes a ridiculous amount of fabrication, tuning and setup to make a farily low amount of power with a gap at the bottom since they are using a centrifugal unit.

So, as Crayolas last point said, it is a show car.

Since finding a roots blower that will fit on our engine is going to be pretty tough, you would be better off (only if you wanted to make very large amounts of power) using a small turbo for quick spool in line with a big **** unit for the top end power. But in any case, especially on a FWD car, you are better off just finding a properly sized turbo with a moderate boost range.

the new VW engine called TSI is only 1.4 and 170 bhp and it's twincharged

The point isnt how much power it makes or the size of the engine, it is what types of chargers are used. Using a centrifugal SC with a turbo really isnt hitting the point of doing this.

it's also known to some automobile manufacturers as Bi-charging. Mostly used in turbo charged cars. it's usualy called bi turbo.

and as far as a twincharged TSI motor. i don't think there is. i do belive in my line of work i'd know about it. and i've yet to hear anything along those lines.

They do have a sequentially (they call it twin) charged setup with a supercharger in front of a turbo. However, I really dont know if it is on the production vehicles yet.. I dont keep up with VW very much honestly.

The sequential/twin interchange of words has been out for a long time.. although I (since it just makes sense if you pay attention to the words) find it a bit strange. Twin charging makes sense when you have a V motor with identical units, one on each bank (hence the word twin). Sequential makes sense with two units running...... sequentially

I guess it is just like "intercooler", since they are actually aftercoolers.. unless of course one is placed in between stages of a multistage system, which is where "intercooler" came from


ahhh the semantics!
