twin F/I
 

i think it would be intereseting if the rx8 had twin sequential turbos like the rx7.....? has anyone else had this thought?

many people have thought of it but in reality it does not make much sense. Though the 3rd Gen's did offer a TT FI system, many owners chose to take out the TT's and go with one larger snail for better performance.

I believe same would be true with an 8.

NO. SINGLE FAT TURBO.......

what kinda numbers could you expect with those lil baby turbs

nice work looks sick

yet again....

yet again lol

Sequential turbos sound like a great idea in theory, but in practice from what I understand are a huge pain in the ass. Most people modifying the Rx7 as mentioned above ditched the twin-sequential setup for a single big turbo. Getting the changeover from the early turbo to the second one is a pain and reliability suffers. Considering reliability is not something that comes in large amounts with FI rotary engines its probably not a good idea to do anything making them less so.

exhaust flow from a rotary far exceeds the same displacement piston.

3071R can do 400 hp and will spool up under 3,000 rpm. So unless you want to go much higher than 400, I don't see the point besides making your vehicle prone to having issues by complicating the FI setup.

Let's go twin 3071R :aroused:

twin is old school. the new thing is quad turbos.

quad turbo on a quad rotor rotary.

1 turbo per rotor!

the problem with the renesis is that it shares one of exhaust ports between the rotors.

You guys are hilarious. :)

Title says twin fi, maybe he means a supercharged turbo setup :lol:

Been discussed, exoticspeed is supposedly devoping a setup (or was in the past) - search.

nvm, looks like that blue car may indeed be eoticspeed's lol

So....... pretty much what we have happening here is that turbo design and manufacturing progresses and improves and those who don't know/understand this seem to want to reach back in the dustbin of automotive history and apply old technologies/lines of thought to today's cars.

Two turbos? Simply a showcase vehicle.

What about if you have a single turbo with a turbonator? That would be twin FI..

Technically, that is called "compound supercharging".

you REALLY wanna be different?? Go for Twin Pettit Superchargers!!
Yeah, just imagine the possibilities! It's mind bottling. ;)

actually there is such a thing...saw it at formula D at the little car show that goes on...they had a bimmer with a supercharger and a turbo...supercharger kicks in at 1k rpm and goes till about 3k then the turbo kicks in and handles the rest...no worries for boost lag

way to go MM... you are gonna confuse sooo many people :P
