evening all,
Since I can't find any decent information on the net, I thought I'd ask the question:
(and this is purely because I'm curious and want to know more about turbo's not for any other reason)
what are the pro's / con's for the three main types of turbo setup:
1. twin sequential
2. twin parallel
3. single
Ignore engine / desired use etc.... just an overview would be fantastic.
As I see it (and am happy to be corrected - is what learning is all about):
1. Twin sequential: good all round, small turbo comes on boost early feeds bigger turbo, gives good power across rev range (similar to supercharger setup for power production??) but may run out of puff at higher end of rev range (??)
2. Twin parallel: Suffers from lag down low, but once gets higher in the rev range, produces a more noticable amount of power for mid to high revs...
3. Single: depending on size of turbo suffers from lag down low, but once up making boost would make more power - due to usually being a larger turbo? better for drag racing and the like?
Given the above (and as I said happy to be corrected) that would make the ideal street car - one you don't want a belting of power all at once..but smooth...a sequential setup?
Anyway Cheers for any answers.
I always know I can get some form of answer from toymods
