Correct me if i'm wrong but weren't Jez (jezzaG60) and Si @ RK Rngineering doing this?

The easiest entry into this would be to drolp a TSI engine in I would have thought... there are bound to be some second hand ones soon as they've been on the roads over 6 months...

Sod that, if they are making a 2l TSI then that would be the one to use!

 

Good platform for some serious power, just need someone to produce uprated roots chargers to completment a bigger turbo.

Nah, twin turbos 8)

Nah, twin turbos 8)

 

Interesting plan, small one on the front and a big one on the back, bet it would be really crap until the first turbo spooled up though!

Thats the hole point of twin turbos the small one will spool straight away and when that puffs out the bigger one will take over.

So you have no lag :twisted:

um... Guys, that's not a twin turbo setup... :roll:

 

Twin turbo setups use 2 identical turbos, one each for half of the engine's cylinders (eg one turbo for left bank and one for the right bank on a V engine...)

BI-TURBO setups use 2 different turbos, one for low end, one for high end... ;)

Twin turbo, bi-turbo, sequential turbo - not an exact science in terms of how they are described.

 

The 335i BMW is set-up as Henny describes a bi-turbo but BMW call it sequential turbocharging

[Kevin Bacon 5]

Sequential turbo is one small one and then a bigger one, that's what sequential means, one followed by the next!....so yes, BMW are using the word incorrectly. There's as you say, is a turbo per bank, so twin or bi turbo.

 

I believe the 335d uses sequential turbos though.

 

When have BMW ever made sense though? A 3.0 engine with a 335i badge? Or a 2.3 engine with a 325i badge?

not much point on a 4 pot let alone one without 2 banks of cylinders.

 

The subaru legacy B4 is a TT. 0 point. may as well use one good quality turbo.

[Kevin Bacon 5]

Yeah 2.0 and smaller 4 pots don't really have enough exhaust flow to justify two turbos.

 

A GT3071R works very well with 1.4 litre capacity though, as a good mod is one per bank in a Porsche 911 :lol:

there are tohers here in the states as well, but this one is always easiest to find pictures of...

twin turbo is not a preferred setup, spool over from small to large turbo is a common problem..

ecu / boost controlling 2 turbos is tricky..

 

supra and rx-7 are an example of twin turbos as std, supra or skyline where its a 6 cylinder 1x turbo can service each "bank" of cylinders....etc ...esp where there are space constraints..

 

big power always requires big single turbo
