Gtr Twin Turbo Size And Setup

[SKY 34]

hi peeps,

to my understanding there are 3 types of set up you can have for twin turbos,

1) two small turbo running simultaneously producing more power

2) two small turbos, running at different peak boost ( i think I forgot)

3) one small turbo and one large turbo, so that the smaller one helps with reducing turbo lag

I read this long long time ago and can't remmeber which website its from, if someone can refer me to a website.

which one is the GTR? and what turbo size is it running?

cheers peep

You forgot the 4th option... two freakin' massive hairdryers producing loads of serious tire-shredding power!

well, two large turbos will have running simultaneously will have the same setup as option 1. there are only 3 set up I'm quite sure

there is no such thing as option 2 mate. you cannot have 2 turbos running at different boost.

there are 2 types of twin turbo set-ups.

sequential

parallel

sequential set-ups have one small turbo and one larger turbo. the small turbo spools first and once the larger turbo is in it's efficiencey range it comes into play. these set-ups are quite complex and require some tricky valves etc to operate properly. My FD RX-7 has this set-up. when done properly they are quite good. the RX-7 pulls strongly from 2,000rpm, then it starts to taper off at 4500rpm as the small turbo is running out of puff, then at 5,000rpm the big turbo kicks in pulling hard to redline.

parallel set-ups use two equally sized turbos running together. they both run the same boost level. this is the GTR type set-up.
